Levels of organochlorine contaminants in natural bovine milk marketed in Mojuí dos Campos and Belterra, Brazil
Analyzing the organochlorine pesticide (OCP) content in milk is relevant because it helps evaluate the quality of milk that reaches the consumer's table and also helps identify the geographical areas where there is a high possibility of contamination. Accordingly, this pilot project was aimed a...

| Resumo: | Analyzing the organochlorine pesticide (OCP) content in milk is relevant because it helps evaluate the quality of milk that reaches the consumer's table and also helps identify the geographical areas where there is a high possibility of contamination. Accordingly, this pilot project was aimed at determining the extent of contamination by OCP residues and their metabolites in fresh cow's milk in Mojuí dos Campos and Belterra, Pará, using solid-phase extraction (SPE) and gas chromatography coupled with electron capture detection (GC-ECD). The OCPs evaluated in this study were dichlorodiphenyltrichloroethane (DDT) and its metabolites (dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD)), hexachlorocyclohexane (HCH) (α, β, γ, and δ), endosulfanα and β, and endosulfansulfate. None of the thirty bovine milk samples analyzed showed any contamination with OCPs. The OCP content was within the limit of quantification of the method. The results of this study add to the existing knowledge on the quality of bovine milk produced in these locations. However, further research on other environmental matrices is required to confirm the results obtained in this study |
