Presence of pesticides in atmosphere and risk to human health: a discussion for the Environmental Surveillance.

Brazil is the main consumer of pesticides in the world. Large-scale use of these products is likely to contaminate major environmental compartments and expose more people to their toxic effects. Therefore, this literature review was carried out to seek supporting elements for a qualified discussion about the performance of Environmental Surveillance (HS) within the Brazilian Unified Health System (SUS) related to air contamination by pesticides and health risks. Twelve papers were selected and analyzed in this literature review. Of these, only one was published in a specialized public health journal. Notwithstanding this, two epidemiological studies published in the field of environmental sciences investigated the association between air contaminated by pesticides and specific outcomes such as non-Hodgkin's lymphoma (NHL) and amyotrophic lateral sclerosis (ALS). Our findings reflect the lack of studies addressing such issue by public health. The discussion on air contamination by pesticides and potential risks to human health should be expanded by Brazilian science in order to further increase knowledge on the subject and support the HS performance capacity.
