Copper, zinc, cadmium and lead inputs and outputs in the maternity section of a commercial shrimp hatchery

The aim of this work was to determine the amounts of copper, zinc, cadmium and lead which enter the tanks of the maternity section of a Mexican commercial hatchery, and those that are discharged to the environment. The most important inputs of Cu were chemicals for water treatment and disease preven...
