Applicability of UV absorbance as an indicator of Atrazine presence into risk management of water supply watersheds

The type of hazards and hazardous events in watersheds, depend on land uses around them. Atrazine is an organic pollutant widely applied as a pesticide it potential chemical hazard present water sources, which cause pollution negative effects aquatic life human health, due to its high solubility persistence soil. However, for developing countries, monitoring quantification atrazine can be complex costly; thus, contribute establishing strategies risk assessment supply was evaluated the use easy, rapid low-cost technique such ultraviolet (UV) absorbance identify presence atrazine. It conformed distilled surface samples doped with Atrazine, there were correlated UV typical spectrum indicator material (wavelength λ: 200 - 300 nm). optimal λ range 203 223 nm this substance at levels possible found being UV223 more adequate than UV254, used natural matter, shows that complementary tool drinking systems.
