VEIGA, Marcelo Motta; SILVA, Dalton Marcondes; VEIGA, Lilian Bechara Elabras  and  FARIA, Mauro Velho de Castro. Pesticide pollution in water systems in a small rural community in Southeast Brazil. Cad. Saúde Pública [online]. 2006, vol.22, n.11, pp.2391-2399. ISSN 1678-4464.

Recent advances in analytical techniques allow identifying pesticide pollution in water systems. In small rural communities, the negative effects of pesticide pollution can be aggravated by the lack of infrastructure and adverse socioeconomic conditions. This study investigated pesticide pollution in potential water supply sources in a tomato growing area in Paty do Alferes, Rio de Janeiro State, Brazil. The study selected 27 points where five monthly samples were collected. Pesticide pollution was determined by analyzing acetyl-cholinesterase inhibition. In 19 of the 27 sample points, some pesticide pollution was detected, and in two points the pesticide pollution was above the permitted limits. The results thus proved the incidence of pesticide pollution in water sources in Paty do Alferes that could jeopardize the local population's health.
