Atmospheric Occurrence of Organochlorine Pesticides and Inhalation Cancer Risk in Urban Areas at Southeast Brazil.

Organochlorine pesticides (OCPs) have been produced for almost a century and some of them are still used, even after they have been proved to be toxic, persistent, bioaccumulative and prone to long-range transport. Brazil has used and produced pesticides in industrial scales for both agricultural and public health purposes. Urban and industrial regions are of special concern due to their high population density and their increased exposure to chemical pollution, many times enhanced by chemical production, application or irregular dumping.

Prevalence of liver diseases as referred by people living in the Santos and São Vicente Estuary.

The Santos and São Vicente Estuary has suffered extensively over the years from irregular industrial deposits. The present study aimed to evaluate liver disease prevalence and potential associated risk factors in four of the Estuary's areas (Pilões and Água-Fria, Cubatão Center, Continental São Vicente, and Guarujá) and a reference area (Bertioga). This study consisted of a cross-sectional study design, in which a questionnaire was used to collect information in 820 households at each of the study areas.
