TAILIEUCHUNG - RE-EVALUATION OF SOME ORGANIC CHEMICALS, HYDRAZINE AND HYDROGEN PEROXIDE

The objective of waste water treatment is to prevent large quantities of substances to reach and impact the environment in high doses and concentrations. Areas of high population densitiy naturally are areas were production of sewage sludge is high (see Figure 1-1). Presently about 8 million t of sewage sludges (MAGOAROU 2000) are produced each year in the EU member states (Table 1-1). Its high content of organic materials, of nitrogen and phosphorous suggest their use as soil conditioner and fertilizer in agriculture. Consequently it is one of the EU policies to enhance sludge use in agriculture (MARMO 2000). . | WORLD HEALTH ORGANIZATION INTERNATIONAL AGENCY FOR RESEARCH ON CANCER IARC MONOGRAPHS ON THE EVALUATION OF CARCINOGENIC RISKS TO HUMANS VOLUME 71 RE-EVALUATION OF SOME ORGANIC CHEMICALS HYDRAZINE AND HYDROGEN PEROXIDE 1999 I A R C LYON FRANCE WORLD HEALTH ORGANIZATION INTERNATIONAL AGENCY FOR RESEARCH ON CANCER IARC MONOGRAPHS ON THE EVALUATION OF CARCINOGENIC RISKS TO HUMANS Re-evaluation of Some Organic Chemicals Hydrazine and Hydrogen Peroxide VOLUME 71 This publication represents the views and expert opinions of an IARC Working Group on the Evaluation of Carcinogenic Risks to Humans which met in Lyon 17-24 February 1998 1999 IARC MONOGRAPHS In 1969 the International Agency for Research on Cancer IARC initiated a programme on the evaluation of the carcinogenic risk of chemicals to humans involving the production of critically evaluated monographs on individual chemicals. The programme was subsequently expanded to include evaluations of carcinogenic risks associated with exposures to complex mixtures life-style factors and biological agents as well as those in specific occupations. The objective of the programme is to elaborate and publish in the form of monographs critical reviews of data on carcinogenicity for agents to which humans are known to be exposed and on specific exposure situations to evaluate these data in terms of human risk with the help of international working groups of experts in chemical carcinogenesis and related fields and to indicate where additional research efforts are needed. The lists of IARC evaluations are regularly updated and are available on Internet http . This project has been supported by Cooperative Agreement 5 UO1 CA33193 awarded by the United States National Cancer Institute Department of Health and Human Services. Additional support has been provided since 1986 by the European Commission since 1993 by the United States National Institute of Environmental Health Sciences and since 1995 by the United States .
