ABSTRACT
Tenofovir disoproxil fumarate (TDF) is a drug used in HIV treatment, and several studies have detected its presence in surface water. Furthermore, more information on its environmental impact is needed in the scientific literature. Thus, due to the lack of data on the impact of this drug, and its presence in different waters of the world, this work aimed to evaluate the potential toxicological effects of TDF on the mollusk Biomphalaria glabrata in vivo and in vitro. For in vitro analysis, hemocytes were exposed to different drug concentrations for 1 h and evaluated for feasibility, and phagocytic and metabolic activity. The in vivo analysis consisted of the exposure of groups of five mollusks, in triplicate, at the same drug concentrations for 72 h and 21 days, evaluating mortality, and mollusk and hemolymph behavior. Although the exposure of the mollusk to TDF did not reduce its survival, however it was toxic to its hemocytes. Even if toxicity was identified on the mollusk and its hemocytes initially, further studies should be conducted to understand the effects of this residue on the environment and different life stages of the mollusk because, per the Globally Harmonized System of Classification and Labeling of Chemicals, for aquatic ecosystems, the results obtained were classified as toxic (EC50% 2.65 [1.98; 5.29] mg/L) and could cause unfeasibility in hemocytes at concentrations below 10 mg/l.
