Protecting the environment: the role of environmental management systems.

Environmental management and auditing systems are increasingly important. They have significant roles to play in relation to environmental protection, workplace safety and public health. Businesses and non-commercial organisations adopt such systems for a variety of reasons. The extent to which they are used varies very considerably between developed countries. The effectiveness of national regulatory systems seems to be a major factor. In the United Kingdom environmental regulators have traditionally sought the voluntary compliance of businesses. This strategy is closely associated with the near absence of administrative penalties. It seems that a wide range of environmental administrative penalties will be introduced in the near future. This may greatly encourage more firms to introduce environmental management and auditing systems.

Cancer mortality in an area of Campania (Italy) characterized by multiple toxic dumping sites.

Several recent studies have documented that a widespread practice of dumping toxic wastes has taken place for many years in the Provinces of Naples and Caserta. Extensive programs of environmental monitoring are currently ongoing in the area. In this frame, the Department of Civil Defence of the Italian Government has appointed an ad hoc study group in order to assess the health status of the population resident in the area of interest. The first investigation performed by the study group has been a geographic study on cancer mortality and occurrence of malformations in 196 municipalities constituting the two Provinces. The study detected an area located in the southeastern part of the Province of Caserta and in the northwestern part of the Province of Naples, where cancer mortality and congenital malformations show significantly increased rates with respect to expected figures derived from the regional population. The area highlighted by the study is, in general terms, overlapping with the area where most illegal dumping of toxic wastes took place. It is now recommended that mortality studies be extended to take into account other health outcomes, to search for correlations with environmental exposures, and consider possible confounding factors.

Municipal solid waste disposal in Portugal.

In recent years municipal solid waste (MSW) disposal has been one of the most important environmental problems for all of the Portuguese regions. The basic principles of MSW management in Portugal are: (1) prevention or reduction, (2) reuse, (3) recovery (e.g., recycling, incineration with heat recovery), and (4) polluter-pay principle. A brief history of legislative trends in waste management is provided herein as background for current waste management and recycling activities. The paper also presents and discusses the municipal solid waste management in Portugal and is based primarily on a national inquiry carried out in 2003 and directed to the MSW management entities. Additionally, the MSW responsibility and management structure in Portugal is presented, together with the present situation of production, collection, recycling, treatment and elimination of MSW. Results showed that 96% of MSW was collected mixed (4% was separately collected) and that 68% was disposed of in landfill, 21% was incinerated at waste-to-energy plants, 8% was treated at organic waste recovery plants and 3% was delivered to sorting. The average generation rate of MSW was 1.32 kg/capita/day.

Mammalian cell-derived somatropin : a review of its use in the management of HIV-associated wasting.

HIV-associated wasting, characterised by progressive loss of lean body mass and bodyweight, remains a significant problem in the era of highly active antiretroviral therapy (HAART). Loss of body cell mass, a component of lean body mass, is associated with decreased survival. Somatropin (recombinant human growth hormone) derived from mammalian cells (Serostim) is the only US FDA-approved treatment indicated to increase lean body mass, bodyweight and physical endurance in HIV-associated wasting. Somatropin 0.1 mg/kg/day administered subcutaneously for 12 weeks effectively increased work output, bodyweight and lean body mass and improved health-related quality of life (HR-QOL), compared with placebo, and had a generally manageable tolerability profile in a large randomised study in patients with HIV-associated wasting. Potential areas for further research include determination of longer-term efficacy and tolerability, the cost effectiveness of treatment, the optimal somatropin dosage, management of patients after 12 weeks' therapy and whether maintenance strategies might exist to maintain accrued lean body mass with lower doses of somatropin. Nevertheless, indications to date are that somatropin is likely to have an important role in the treatment of patients with HIV-associated wasting.

Parenteral packaging waste reduction.

The consumption of pharmaceutical products generates waste materials which can cause significant environmental impact when incinerated or landfilled. The purpose of this work is to stimulate discussion among hospital pharmacists and purchasing managers relating to the waste management aspects of their purchasing decisions. As a case study example, a number of commercially available "single use" parenterals are evaluated from a waste reduction perspective, for both the product container and for the packaging of these containers. Glass vials are non-incinerable, and are currently non-recyclable due to the higher melting temperatures required for borosilicate glass. However, plastic vials are potentially both incinerable and recyclable. Packaging quantities are considerably lower for plastic vials on a unit container basis, and also vary to a measurable degree between different manufacturers for a given type of container material. From an environmental perspective, waste reduction potential should become an important criterion in the selection of pharmaceutical products for hospital use.

Gray correlation analysis and prediction models of living refuse generation in Shanghai city.

A better understanding of the factors that affect the generation of municipal living refuse (MLF) and the accurate prediction of its generation are crucial for municipal planning projects and city management. Up to now, most of the design efforts have been based on a rough prediction of MLF without any actual support. In this paper, based on published data of socioeconomic variables and MLF generation from 1990 to 2003 in the city of Shanghai, the main factors that affect MLF generation have been quantitatively studied using the method of gray correlation coefficient. Several gray models, such as GM(1,1), GIM(1), GPPM(1) and GLPM(1), have been studied, and predicted results are verified with subsequent residual test. Results show that, among the selected seven factors, consumption of gas, water and electricity are the largest three factors affecting MLF generation, and GLPM(1) is the optimized model to predict MLF generation. Through this model, the predicted MLF generation in 2010 in Shanghai will be 7.65 million tons. The methods and results developed in this paper can provide valuable information for MLF management and related municipal planning projects.

Quantification of sewer leakage: a review.

One of the goals of the APUSS project (assessing infiltration and exfiltration on the performance of urban sewer systems) is to assess sewer exfiltration, in order to support cities and operators to define problem-oriented rehabilitation strategies. In this paper, we review various methods currently used for the estimation of exfiltration and discuss data needs and applicability for rehabilitation planning. Although each approach has its individual advantages and drawbacks, we identified pressure tests and tracer methods to have the highest potential for decision support in rehabilitation planning. With regard to future challenges (e.g., micropollutants) such methods might play a key role in integrated sewer management.

Barriers and solutions in implementing occupational health and safety services at a large nuclear weapons facility.

The Hanford Nuclear Reservation is one of the U.S. Department of Energy's largest nuclear weapons sites. The enormous changes experienced by Hanford over the last several years, as its mission has shifted from weapons production to cleanup, has profoundly affected its occupational health and safety services. Innovative programs and new initiatives hold promise for a safer workplace for the thousands of workers at Hanford and other DOE sites. However, occupational health and safety professionals continue to face multiple organizational, economic, and cultural challenges. A major problem identified during this review was the lack of coordination of onsite services. Because each health and safety program operates independently (albeit with the guidance of the Richland field operations office), many services are duplicative and the health and safety system is fragmented. The fragmentation is compounded by the lack of centralized data repositories for demographic and exposure data. Innovative measures such as a questionnaire-driven Employee Job Task Analysis linked to medical examinations has allowed the site to move from the inefficient and potentially dangerous administrative medical monitoring assignment to defensible risk-based assignments and could serve as a framework for improving centralized data management and service delivery.
