The first diagnosis of risk of environmental contamination was conducted for an area of intense agricultural activity in the semiarid cearense (Baixo Jaguaribe and Litoral de Aracati area). We verified the use of 201 rural products (pesticides) in the region, comprising 151 active ingredients. Regarding the active ingredients evaluated, 15.9% were associated with sediment and 29.8% were dissolved in surface water. The study showed that 13.2% to 36.4% of the active ingredients evaluated were classified as potential contaminants of groundwater resources. The study also revealed the most abundant pesticides and which environmental compartment must be evaluated.
