In this paper, it is analyzed the temporal variation of organochlorine pesticides (OCPs) in water and sediments from a river influenced by the activity in an agricultural field in a tropical country during the period 2013-2016. The novelty consists of increasing the studies of concentrations of OCPs in water and sediments of rivers for contributing to establish thresholds of concentrations that allow to protect the biota in soils and waters. The mean values of the OCPs dissolved in water and sorbed on sediments varied as follows: p.p'-DDT (0.001 – 0.022 μg.L-1), (0.1 – 8.24 μg.kg-1), o.p'-DDT (0.001-0.021 μg.L-1), (0.51 – 5.76 μg.kg-1), p.p'-DDD (0.001-0.01 μg.L-1), (0.14 – 1.96 μg.kg-1), p.p'-DDE (0.001-0.027 μg.L-1), (0.52 – 7.32 μg.kg-1), o.p'-DDE (0.001-0.041 μg.L-1), (0.2 – 5.52 μg.kg-1), Aldrin (0.004-0.053 μg.L-1), (0.23 – 8.22 μg.kg-1), Dieldrin (0.001-0.032 μg.L-1), (1.13 – 6.82 μg.kg-1) and Endrin (0.001-0.008 μg.L-1), (1.16 – 7.60 μg.kg-1). The management of OCPs by the activity in the agricultural field is being controlled.
