This article presents the results of a heath risk assessment in Cidade dos Meninos, an area contaminated with organochlorine pesticide residues located in the county (municipality) of Duque de Caxias, Rio de Janeiro State, Brazil. The Agency for Toxic Substances and Disease Registry (ATSDR) risk assessment methodology was applied. The following organochlorine compounds exceeded the established limits and were considered target pollutants: HCH and its isomers (in eggs, milk, and soil); DDT and its metabolites; trichlorobenzenes; trichlorophenols; dioxins and furans (eggs and soil). For all the substances studied (with the exception of trichlorophenols), the estimated doses exceeded the minimum risk levels for chronically exposed children and adults. According to the ATSDR classification, the area was considered an "urgent public health hazard" because of its high and serious exposure to substances that are dangerous to human health.

Abstract Study was carried out to determine the concentration and bioaccumulation of pesticide residues in edible fish from river Ganga, India, to assess human health risk via consumption of fish. Two commonly edible fish species bagrid catfish and common carp were collected. The n-hexane extract of the muscle tissues were characterized by gas chromatography coupled to mass spectrometry and quantified by electron capture detector for pesticide residues. Bioaccumulation factors (BAFs) in common carp of pesticides were found to be higher than those in bagrid fish. Daily exposures of pesticides for consumers via fish consumption were determined by calculating and comparing estimated daily intake (EDI) with ADI values. The EDI results in our study were insignificantly high from ADI values. Non-carcinogenic and carcinogenic risks were evaluated by Target hazard quotient (THQ) and risk ratio (R), respectively. Hazard quotients (THQ) were found to be lower than the set 1.0, inferring non-carcinogenic risk by consumption of fish from the river. Regard to contaminants carcinogenic affects the total risk ratio (R) value of pesticides were found lower than threshold of tolerable risk except of heptachlor indicating carcinogenic risk via consumption of fish. The results demonstrate that due to increased pollution in the ecosystem required more attention.
