Notes:
The environmentally hazardous organic substances in the waste water from the manufacture of chlorophenoxyalkanoic acids have been identified and semiquantified before and after passing through a biological treatment plant for municipal sewage, the secondary effluent of which is discharged into a marine ecosystem. The organics belong to three groups: (i) chlorophenols; (ii) chlorophenoxyalkanoic acids; and (iii) chlorinated neutrals. The removal of chlorophenols and phenoxyalkanoic acids was shown to be good, with a 90% overall reduction of chlorinated substances in the sewage passing through the treatment plant. The lowest reduction occurred for the polychlorinated compounds. Two chlorobenzofurans among the chlorinated neutrals were preliminarily identified.
