Composti organoalogenati alifatici e contaminazione delle acque superficiali.

A brief review of the effects of halogenated organic compounds on the fluvial ecosystem is folloed by results from a detailed monitoring of these substances in all the Marches region rivers.The results show generally modest concentrations, except for sporadic peaks for chloroform. Sites revealing significant concentrations of halogenated organic compounds also manifested a worsening of the waters with lessening of E.B.I. Attention is drawn to the negative effects of indiscriminate chlorination of purification plant outputs, as this practice often fails to resolve infective problems and in itself adds toxicity to the watercourses.
