Bioconcentration of atrazine, zinc and iron in the blood of Tilapia sparrmanii (Cichlidae).
1. The bioconcentration of atrazine, zinc and iron in the blood of Tilapia sparrmanii has been determined separately in each of six exposure groups. 2. An increased bioconcentration of atrazine in the blood occurred with an increased exposure concentration. 3. With exposure to zinc, there was a gradual decrease in bioconcentration of zinc in the blood of T. sparrmanii with an increased concentration in the water. 4. A similar tendency was observed during iron exposure, except that the decrease in bioconcentration was not significant.
