Ecotoxicological and genotoxic evaluation of Buenos Aires city (Argentina) hospital wastewater
Hospital wastewater (HWW) constitutes a potential risk to the ecosystems and human health due to the presence of toxic and genotoxic chemical compounds. In the present work we investigated toxicity and genotoxicity of wastewaters from the public hospital of Buenos Aires (Argentina). The effluent fro...
