RESUMO

The IR-spectroscopy results demonstrated that active chlorine in seawater increases the overall toxicity of environment. At low concentrations (up to 0.2 mg/L), this is a result of the formation of organochlorines, and in high concentrations — of peroxide fragments. The threshold concentration of active chlorine for a community of periphyton organisms is 3.0 mg/L; its further growth results in the irreversible oxidative destruction of organic matter of cenosis, and eventually to its death.
