Infant Methemoglobinemia in the Transylvania Region of Romania.

The incidence of infant methemoglobinemia reported in three counties of Transylvania, Romania, was evaluated from medical records, field visits, and interviews. Well water was the main source of nitrate for induction of acquired infant methemoglobinemia, which occurred post-breast-feeding when the infants consumed nitrate-contaminated water used in mixing formula. The average age of reported infants with methemoglobinemia was 39 days, supporting earlier observations that infants less than 4 months old are the most susceptible segment of the population. Vitamin C, rather than methylene blue, was the main medical intervention in the Transylvania region. The mean incidence rates of methemoglobinemia in the three counties (Saut-Mare, Mures, and Bistrita-Nasaud) ranged from 24 to 363 per 100,000 live births over a five-year period (1990-1994). These rates are below earlier reported incidence rates of up to 13% (13,000 per 100,000 live births). Three selected case reports are presented to describe hospital/clinic data, well-water data, and infant feeding practices. Recommendations for appropriate intervention programs are described. The significances of possible physical and neuropsychological effects on the development of children following methemoglobinemia are discussed and the need for further investigations is outlined.

ISO 14000: Origin, Structure, and Potential Barriers to Implementation.

The ISO 14000 is likely to become the international standard for environmental management. At present, it is an evolving series of individual voluntary standards and guideline reference documents that provide business management with the structure for managing environmental impacts. These encompass environmental management systems, environmental audits, eco-labeling, environmental performance evaluations, life-cycle assessment, and environmental aspects in product standards. The authors present the rationale for the ISO 14000 and the steps in its evolution so far, as well as its present provisions and their implications and its position with regard to regulatory agencies. Particular attention is paid to the consequences of voluntary disclosure and correction of violations. Hanley & Belfus, Inc. Int J Occup Environ Health 1077-3525 2 2 1996 April/June Perspectives on Rural Environmental Health in Central Europe 125 134 EN Tomas Trnovec Burton C. Kross CIREH-Room 352, International Center, University of Iowa, Iowa City, IA 52242, USA. Emil Ginter Life expectancy is about five to seven years less in Central European countries than in comparable countries in Western Europe. Environmental and occupational health risk factors, along with the socioeconomic and political conditions that have prevailed in this region for the past 40 years, are suspected contributing factors to this condition. The initial impression among observers was that environmental pollution by industry was the primary source of contamination leading to human health effects. Current thinking by the authors recognizes that combinations of personal habits, local environmental emissions (home heating), and occupational risk factors are more likely to be influencing the health of this region, particularly in rural areas. A predictive model for standard mortality rates determined that only three potential risk factors were statistically significant: consumption of alcoholic beverages, consumption of citrus fruits, and consumption of cereals. Additional emphasis should be placed on defining risk factors in rural areas of Central Europe, and designing intervention strategies to address these factors.
