The Government of India has promulgated the Hazardous Waste (Management & Handling) Rules (HW (M&H)) in 1989 through the Ministry of Environment and Forests (MOEF) under the aegis of Environment (Protection) Act [E(P) Act], 1986. Also in order to encourage the effective implementation of these rules, the MOEF has further brought out the Guidelines for HW (M & H) in 1991. However, case studies r...

One of the actual global problems is an issue of waste, its formation, disposal and possible secondary processing. Another closely related issue concerns hazardous waste which represents a potential threat to environment and human health. This paper is focused on an area of waste containing hexavalent chromium arising especially from leather industry. Hexavalent chromium is classified as a carc...

Concern about environmental pollutants has increased; however, it remains unclear whether chronic exposures to toxic chemicals in the environment occur at doses sufficient to produce adverse health effects in humans. To date, community studies have not adequately addressed this question. In this study, the authors linked two existing data bases of the New York State Department of Health to eval...

The public health impacts associated with stack emissions from hazardous waste incinerators have become a major concern in recent years. Most evaluations of incinerator stack emissions have focused on three classes of compounds: metals, semivolatile, and volatile compounds. These investigations have been complicated by the difficulty and expense of analyzing the emissions and the limited amount...

T management of toxic waste has become an increasingly global business. The worldwide generation of hazardous waste is currently around 440 million tons, of which an estimated 10 percent makes its way across international boundaries.1 A variety of industries generate toxic wastes, ranging from chemicals to electronics and from plastics to metal plating. These toxic wastes have adverse affects o...

Ideally, the flue gas resulting from high-temperature oxidation of hydrocarbons (HC) contains CO 2 , H 2 O, N 2 , O 2 and some acceptable levels of oxides of nitrogen (NOx) and oxides of sulfur (SOx). In reality, the flue gas from a combustion process contains CO 2 , H 2 O, N 2 , O 2 and some concentration of carbon monoxide (CO), unburned hydrocarbons (UHC), NOx and SOx .

OBJECTIVES Infected hospital wastes are among hazardous wastes, and special treatment methods are needed for their disposal. Having information about present status of medical waste management systems is of great importance in finding weak, and for future planning. Such studies have not been done for most of the hospitals in Iran. METHODS This paper reports the results of a study on the prese...

The Regional Ground Water Forum is a group of ground-water technical specialists, representing EPA's Regional Offices, organized to exchange up-to-date information related to groundwater remediation at hazardous waste sites. Proper site characterization has been identified by the EPA Regional Ground Water Forum as a major issue of concern for decision-makers at many hazardous waste sites. In or...

Three to 4 million children and adolescents in the United States live within 1 mile of a federally designated Superfund hazardous waste disposal site and are at risk of exposure to chemical toxicants released from these sites into air, groundwater, surface water, and surrounding communities. Because of their patterns of exposure and their biological vulnerability, children are uniquely suscepti...
