“…Pesticides and veterinary drugs, accumulated in living organisms, can be transferred through different trophic levels across the food chain. In risk analysis the knowledge about the different exposure routes is important, which is obtained by trophic transfer studies [55,63].…”

“…Any impact at low levels of the food chain, such as algae which are primary producers, can exert adverse effects at higher trophic levels, such as fishes [55,64]. In this context, Dionisio et al [55] exposed cultures of the microalgae Raphidocelis subcapitata to sublethal concentrations of the herbicide atrazine encapsulated in zein and poly(epsilon-caprolactone) nanoparticles during eight days of growth to bioconcentrate the nanopesticide in algal cells. These organisms were used to feed zebrafish (Danio rerio) larvae, in which the growth of the body size was evaluated.…”

The quality of the aquatic environment can be compromised by the practice of intensive use of pesticides in agriculture and by the misuse of veterinary drugs. Therefore, organisms that live in aquatic ecosystems may be affected due to the presence of these chemicals, through runoff, leaching and other processes. Exposure of aquatic organisms to these xenobiotics could pose health risks. Consequently, there is a growing interest in predicting the bioaccumulation of these substances in aquatic biota from experiments conducted under laboratory conditions. Studies on fish have been performed due to its importance as human food and their wide distribution in most of the aquatic environment. Thus, this article reviews the concepts on determining the accumulation of pesticides and veterinary drugs in fish. The risk regarding the consumption of fish containing residues of these chemical agents, the acceptable daily intake, the testing protocols and the analytical techniques used to determine the residues of these substances in fish tissues are discussed. An emphasis on studies involving tilapia as the test organism was included because, according to Food and Agricultural Organization (FAO), this species is one of the most cultivated in the world.
