Environmental health impact assessment: evaluation of a ten-step model.

"Environmental impact assessment" denotes the attempt to predict and assess the impact of development projects on the environment. A component dealing specifically with human health is often called an "environmental health impact assessment." It is widely held that such impact assessment offers unique opportunities for the protection and promotion of human health. The following components were identified as key elements of an integrated environmental health impact assessment model: project analysis, analysis of status quo (including regional analysis, population analysis, and background situation), prediction of impact (including prognosis of future pollution and prognosis of health impact), assessment of impact, recommendations, communication of results, and evaluation of the overall procedure. The concept was applied to a project of extending a waste disposal facility and to a city bypass highway project. Currently, the coverage of human health aspects in environmental impact assessment still tends to be incomplete, and public health departments often do not participate. Environmental health impact assessment as a tool for health protection and promotion is underutilized. It would be useful to achieve consensus on a comprehensive generic concept. An international initiative to improve the situation seems worth some consideration.

Assessing health impact assessment: multidisciplinary and international perspectives.

Health impact assessment (HIA) seeks to expand evaluation of policy and programmes in all sectors, both private and public, to include their impact on population health. While the idea that the public's health is affected by a broad array of social and economic policies is not new and dates back well over two centuries, what is new is the notion-increasingly adopted by major health institutions, such as the World Health Organisation (WHO) and the United Kingdom National Health Services (NHS)-that health should be an explicit consideration when evaluating all public policies. In this article, it is argued that while HIA has the potential to enhance recognition of societal determinants of health and of intersectoral responsibility for health, its pitfalls warrant critical attention. Greater clarity is required regarding criteria for initiating, conducting, and completing HIA, including rules pertaining to decision making, enforcement, compliance, plus paying for their conduct. Critical debate over the promise, process, and pitfalls of HIA needs to be informed by multiple disciplines and perspectives from diverse people and regions of the world.

A health impact assessment of an environmental management plan: the impacts on physical activity and social cohesion.

ISSUE ADDRESSED: This article describes a prospective health impact assessment (HIA) on a local government environmental management plan, the Shellharbour Foreshore Management Plan (SFM Plan). The health outcomes of interest were physical activity and social cohesion. METHODS: The procedures undertaken include: screening; scoping; assessment of potential health impacts; negotiation; and decision-making. The potential positive and negative health impacts of the SFM Plan were assessed and opportunities to enhance the positive and mitigate the negative were identified. RESULTS: Implementation of the SFM Plan was supported as the HIA showed a potential to benefit the health of local residents and visitors to the Shellharbour Foreshore area by increasing physical activity and social cohesion. CONCLUSION: The HIA provided a useful framework for establishing a collaborative relationship between the local government and health sector. It improved the local government's understanding of the inter-relationship between the environment and physical activity and social cohesion and enabled health authorities to have an impact on a capital works program to maximise health gain.

Long-term health impacts of forced early retirement among steelworkers.

BACKGROUND: Previous studies of the health impacts of retirement have not investigated the effects of forced early retirement following plant closings. METHODS: Using a geriatric database representative of elderly people, the health impacts on employees forced to take early retirement from steel mills in the Youngstown, Ohio, area were assessed. A study group of forced early retirees was compared with two control groups: (1) regular steel industry retirees, and (2) regular retirees from jobs outside the steel industry. Utilizing multivariate analysis techniques, the effects of retirement on a number of different health measures were isolated. RESULTS: Over the long term, the health of forced retirees does not seem adversely affected by sudden job loss and unexpected retirement, at least in the steel industry. CONCLUSIONS: Continuity theories of retirement--that workers do not experience abrupt catastrophic changes in lifestyle and in health--best explain the lack of negative health impacts.

Health impact assessment: a tool to help policy makers understand health beyond health care.

Health impact assessment (HIA)--a combination of methods to examine formally the potential health effects of a proposed policy, program, or project--has received considerable interest over the past decade internationally as a practical mechanism for collaborating with other sectors to address the environmental determinants of health and to achieve more effectively the goals of population health promotion. Demand for HIA in the United States seems to be growing. This review outlines the common principles and methodologies of HIA and compares different approaches to HIA. Lessons learned from the related field of environmental impact assessment and from experience with HIA in other countries are examined. Possible avenues for advancing both the field and the broader goals of population health promotion are outlined.

Including health in transport policy agendas: the role of health impact assessment analyses and procedures in the European experience.

From the mid-1990s, research began to highlight the importance of a wide range of health impacts of transport policy decisions. The Third Ministerial Conference on Environment and Health adopted a Charter on Transport, Environment and Health based on four main components: bringing awareness of the nature, magnitude and costs of the health impacts of transport into intergovernmental processes; strengthening the arguments for integration of health into transport policies by developing in-depth analysis of the evidence; developing national case studies; and engaging ministries of environment, health and transport as well as intergovernmental and nongovernmental organizations. Negotiation of the Charter was based on two converging processes: the political process involved the interaction of stakeholders in transport, health and environment in Europe, which helped to frame the issues and the approaches to respond to them; the scientific process involved an international group of experts who produced state-of- the-art reviews of the health impacts resulting from transportation activities, identifying gaps in existing knowledge and methodological tools, specifying the policy implications of their findings, and suggesting possible targets for health improvements. Health arguments were used to strengthen environmental ones, clarify costs and benefits, and raise issues of health equity. The European experience shows that HIA can fulfil the need for simple procedures to be systematically applied to decisions regarding transport strategies at national, regional and local levels. Gaps were identified concerning models for quantifying health impacts and capacity building on how to use such tools.

Oral health impacts on daily living related to four different treatment protocols for chronic periodontitis.

BACKGROUND: The aims of this study were to evaluate the oral health impacts perceived by patients submitted to different treatments of chronic periodontitis and their association with clinical parameters. METHODS: Sixty patients were assigned to one of the following therapeutic groups: control, treated with full-mouth scaling and root planing (SRP); test 1, treated with SRP and 400 mg systemically administered metronidazole (MET) three times per day for 10 days; test 2, treated with SRP and professional supragingival plaque removal (PP) every week for 3 months; and test 3, treated with SRP and MET plus PP. Clinical periodontal measurements and data regarding patients' oral health impacts (perceived impacts on bleeding gums, gingival recession, sensitivity to cold, packing foods, aesthetics, bad breath, and tooth mobility) were collected at baseline and 3 months after therapy. RESULTS: All groups presented significant improvement in oral health perceived impacts. There was no statistically significant difference in the improvement of oral health impacts among groups subjected to different treatments. The clinical data of percentage of deep probing depth, deep clinical attachment level, and bleeding on probing were found to be correlated significantly with oral health impacts. CONCLUSIONS: Periodontal treatment leads to a significant reduction of self-perceived impacts regardless of the non-surgical treatment protocol employed. Most of the clinical data were associated with oral health impacts.

Conceptual and methodological challenges in predicting the health impacts of climate change.

Describing (not to mention quantifying) the anticipated adverse health impacts of global climate change poses basic challenges to biomedical science. First and foremost, it is beset with uncertainties and complexities; it is necessarily an 'If-Then' exercise, that takes as given climatologists' estimates of the plausible range of greenhouse-induced climate change over the coming century. The health impacts of climate change would generally not occur via the familiar direct-acting mechanisms that characterise local environmentally-induced toxicology or pathophysiology; therefore they would lack the mechanistic directness-of-effect that epidemiological research methods are best equipped to study. Rather, the health impacts would occur on a larger scale, and would result predominantly from perturbations of natural biogeochemical systems that reduce Earth's capacity for life support. Therefore, scientists will need to address the assessment of impacts within an ecological framework, and with an unusually long time horizon. This assessment requires a new capacity for systems-based thinking, predictive modelling, and dealing with uncertainty. Scientists, policy-makers and general public will have to adjust to unfamiliar styles of 'anticipatory' science, with an unusual overlay of uncertainty and provisionality.

Environmental and human health impacts of growing genetically modified herbicide-tolerant sugar beet: a life-cycle assessment.

There is ongoing debate concerning the possible environmental and human health impacts of growing genetically modified (GM) crops. Here, we report the results of a life-cycle assessment (LCA) comparing the environmental and human health impacts of conventional sugar beet growing regimes in the UK and Germany with those that might be expected if GM herbicide-tolerant (to glyphosate) sugar beet is commercialized. The results presented for a number of environmental and human health impact categories suggest that growing the GM herbicide-tolerant crop would be less harmful to the environment and human health than growing the conventional crop, largely due to lower emissions from herbicide manufacture, transport and field operations. Emissions contributing to negative environmental impacts, such as global warming, ozone depletion, ecotoxicity of water and acidification and nutrification of soil and water, were much lower for the herbicide-tolerant crop than for the conventional crop. Emissions contributing to summer smog, toxic particulate matter and carcinogenicity, which have negative human health impacts, were also substantially lower for the herbicide-tolerant crop. The environmental and human health impacts of growing GM crops need to be assessed on a case-by-case basis using a holistic approach. LCA is a valuable technique for helping to undertake such assessments.

[Health impact assessment of building and investment projects].

For regional planning and approval procedures for building projects of a certain order of magnitude and power rating according to the German Federal Act on the Prevention of Emissions with Integrated Environmental Impact Assessment (EIA), the German public health departments, acting as public authorities, increasingly perform health impact assessments (HIA). The amended Act on Environmental Impact Assessment, the Decree on industrial plants which require approval (4th Federal Decree on Emission Prevention) and the Health Service Acts of the Federal States of Germany form the legal basis for the assessment of health issues with regard to approval procedures for building and investment projects. In the framework of the "Action Programme for the Environment and Health", the present article aims at making this process binding and to ensure responsibility and general involvement of the Public Health departments in all German Federal States. Future criteria, basic principles and procedures for single-case testing as well as assessment standards should meet these requirements. The Federal Ministry for the Environment and the Federal Ministry for Health should agree on Health Impact Assessment (HIA ) as well as on the relaxant stipulations in their procedures and general administrative regulations for implementing the Environmental Impact Assessment Act (EIA). Current EIA procedures focus on urban development and road construction, industrial investment projects, intensive animal husbandry plants, waste incineration plants, and wind energy farms. This paper illustrates examples meeting with varying degrees of public acceptance. However, being involved in the regional planning procedure for the project "Extension of the federal motorway A 14 from Magdeburg to Schwerin", the Public Health Service also shares global responsibility for health and climate protection. Demands for shortest routing conflict with objectives of environmental protection which should be given long-term consideration. Assessing the direct impact of projects on human beings should be rank first in the list of priorities. The Hygiene Institute supports the efforts of the Public Health departments by providing professional consultant services to ensure consistency in the application of procedures.

Health impact assessment of air pollution: providing further evidence for public health action.

Many epidemiological studies have demonstrated the importance of air pollution as a risk factor and characterised dose-response relationships between health endpoints and pollutants. The association between particulate matter (PM) and health is generally regarded as causal, and a nonthreshold linear relationship with, for example, mortality and hospital admission has been observed in several settings. The ubiquitous PM air pollution is likely to have a large overall impact on human health, even if risks are relatively small. There have recently been a large number of papers reporting quantitative estimations of the health impact of PM on health, as measured by the proportion of excess events that are attributable to PM exposures in the general population, mainly in industrialised countries. For example, in the eight largest Italian cities it has been estimated that concentrations beyond 30 microg x m(-3) are responsible for about 3,500 extra deaths per year. A similar study has been carried out for France, Austria and Switzerland. These evaluations fill a knowledge gap between the laboratory and clinical studies on the pathophysiological mechanisms, the epidemiological research on the nature and strength of the association at the population level, and the risk management needs for developing appropriate preventive policies. Some limitations in the methodology deserve further research, however health impact assessment type studies are informative and effective tools of communication with the general public and policy makers.

Evaluation as a key part of health impact assessment: the English experience.

Health impact assessment (HIA) is an approach that has experienced increased activity and wide support within England. This is reflected in the large number of HIAs being undertaken at local and regional levels, by the advocacy of HIA in many national policy documents, and by the setting up of specialized HIA posts and centres. To continue this level of support, and to justify any increase, the approach of HIA must show whether and how the HIA approach informs the decision-making process and, in particular, whether it improves health and reduces health inequalities. The first steps in answering these questions have been taken by the partial evaluation of some completed HIAs within England. A description of these evaluations is presented. Work is also progressing on promising practice guidance for practitioners on the topic of evaluating HIAs. The further development of evaluation within HIA is required, at both a practitioner and research level, and provides an exciting opportunity for people and groups to advance the evidence base for HIA, while also proving its place as an effective public health intervention.

Towards health impact assessment of drinking-water privatization--the example of waterborne carcinogens in North Rhine-Westphalia (Germany).

Worldwide there is a tendency towards deregulation in many policy sectors - this, for example, includes liberalization and privatization of drinking-water management. However, concerns about the negative impacts this might have on human health call for prospective health impact assessment (HIA) on the management of drinking-water. On the basis of an established generic 10-step HIA procedure and on risk assessment methodology, this paper aims to produce quantitative estimates concerning health effects from increased exposure to carcinogens in drinking-water. Using data from North Rhine-Westphalia in Germany, probabilistic estimates of excess lifetime cancer risk, as well as estimates of additional cases of cancer from increased carcinogen exposure levels are presented. The results show how exposure to contaminants that are strictly within current limits could increase cancer risks and case-loads substantially. On the basis of the current analysis, we suggest that with uniform increases in pollutant levels, a single chemical (arsenic) is responsible for a large fraction of expected additional risk. The study also illustrates the uncertainty involved in predicting the health impacts of changes in water quality. Future analysis should include additional carcinogens, non-cancer risks including those due to microbial contamination, and the impacts of system failures and of illegal action, which may be increasingly likely to occur under changed management arrangements. If, in spite of concerns, water is privatized, it is particularly important to provide adequate surveillance of water quality.

Public health impact of genetic tests at the end of the 20th century.

PURPOSE: To evaluate genetics tests available for clinical, research, and public health purposes in terms of their public health impact as measured by the number of people who could potentially be tested. METHODS: Genetic tests for the 751 inherited diseases or conditions listed in the GeneTests database as of November 2000, were classified on the basis of their use for population-based testing and the prevalence of the disease or condition being tested. The GeneTests database divides the tests into two groups: those offered for clinical use and those available for research only. RESULTS: Of the 423 clinical tests, 51 had potentially greater impact on public health because of their use in statewide newborn screening programs, other population screening programs, or testing for common diseases with a prevalence over 1 in 2,000 people. Among the 328 tests performed for research purposes only, 18 met the criteria for potentially greater public health impact. CONCLUSIONS: Our classification scheme indicated that fewer than 10% of the genetic tests listed in the GeneTests database at the end of 2000 are highly relevant to public health. The majority of genetic tests are used in diagnosis and/or genetic counseling for rare, single-gene disorders in a limited number of people. However, as more tests are being considered for newborn screening, and associations between genes and common diseases are being discovered, the impact of genetic testing on public health is likely to increase.

A framework for the evidence base to support Health Impact Assessment.

OBJECTIVE: To introduce a conceptual structure that can be used to organise the evidence base for Health Impact Assessment (HIA). BACKGROUND: HIA can be used to judge the potential health effects of a policy, programme or project on a population, and the distribution of those effects. Progress has been made in incorporating HIA into routine practice, especially (in the UK) at local level. However, these advances have mainly been restricted to process issues, including policy engagement and community involvement, while the evidence base has been relatively neglected. RELATING POLICIES TO THEIR IMPACT ON HEALTH: The key distinctive feature of HIA is that determinants of health are not taken as given, but rather as factors that themselves have determinants. Nine ways are distinguished in which evidence on health and its determinants can be related to policy, and examples are given from the literature. The most complete of these is an analysis of health effects in the context of a comparison of options. A simple model, the policy/risk assessment model (PRAM), is introduced as a framework that relates changes in levels of exposures or other risk factors to changes in health status. This approach allows a distinction to be made between the technical process of HIA and the political process of decision making, which involves lines of accountability. Extension of the PRAM model to complex policy areas and its adaptation to non-quantitative examples are discussed. ISSUES FOR THE FUTURE: A sound evidence base is essential to the long term reputation of HIA. Research gaps are discussed, especially the need for evidence connecting policy options with changes in determinants of health. It is proposed that policy options could be considered as "exposure" variables in research. The methodology needs to be developed in the course of work on specific issues, concentrated in policy areas that are relatively tractable. CONCLUSIONS: A system of coordination needs to be established, at national or supranational level, building on existing initiatives. The framework suggested in this paper can be used to collate and evaluate what is already known, both to identify gaps where research is required and to enable an informed judgement to be made about the potential health impacts of policy options. These judgements should be made widely available for policy makers and for those undertaking health impact assessment.

[Outdoor air pollution and its health impacts].

Air pollution is a major blot on our environmental health scorecard. Finding from many epidemiological studies showed that air pollution contributed to many health impact, being harmful to respiratory system, cardiovascular system and immune system, and was associated with declined lung function, increased hospitalization and cardio-respiratory mortality. These health impacts occurred even at exposure levels below those stipulated in current air-quality guidelines. In this paper, some findings from epidemiological studies were reviewed, and some considerations for the future study on this subject were emphasized.
