Chemical name: 1,1'-(2,2,2-trichloroethylidene)bis[4-chloro-benzene] Final regulatory action has been taken for the category: Pesticide Final regulatory action: The chemical is Banned Use or uses prohibited by the final regulatory action: the use is banned as agricultural chemical Pesticide use or uses that remain allowed: the use is prohibited as pesticide The final regulatory action was based on a risk or hazard evaluation: Yes Summary of the final regulatory action: Banned by decree of former USSR Ministry of Health The reasons for the final regulatory action were relevant to: Human health and environment Summary of known hazards and risks to human health: DDT can be absorbed by ingestion, by inhalation and to some extent through the skin. Believed to account for 90% of the DDT stored in the general population . DDT has been found in adipose tissue of large proportions of the population in countries of use. The accumulation of residues in humans and the potential oncogenicity of DDT also contributed to health concerns. Expected effect of the final regulatory action in relation to human health: Reduction and stop of hazards and risks to human health and the environment. Summary of known hazards and risks to the environment: characteristics of DDT to persist, especially in temperate climates and to biomagnify in the food chain led to significant reproductive effects in birds, such as the brown pelican, osprey and eagles, because of egg shell thining. Average half-life of DDT is at least 5 years. Preferentially stored in fat with bioconcentration factors up to 50 000 (fich) or 500 000 (mussel). There were concerns about the general environmental contamination of longlived nature and uncertainly about the eventual adverse impacts on man and the environment because of continuing, long term exposure through water, food and other sources. Expected effect of the final regulatory action in relation to the environment: Reduction of hazards and risks to environment and improvement of environmental state.
