Challenge: availability and quality of water;

Environmental changes are modifying how contaminants behave

on the environment;

Drugs adverse effects on biota and humans.

How much are in human supply reservoirs?

What are their ecotoxicological effects?

How climate change can influence the behavior of drugs on the

environment?

Investigate the presence and ecotoxicological consequences of

drugs in Brazilian aquatic ecosystems.
