摘要

Three short-term assays (the SOS chromotes the Ames-fluctuation test and the newt mieronucleus lest) were carried out to evaluate the gunotqxicity of five chlorinated propanones identified in several chlorinated waters (monochloropropanone, 1,1-dichloropropanonc, 1,3-dichloropropanorie, 1,1,1-trichloropropanone and 1,1,3-trichloropropanone). In the SOS chromotest, all the compounds except monochloropropanone. ware found to induce primary DNA damage in Escherichia coli. With the fluctuation test, allfive ehloropropanones showed rnutagcnic activity on Salmonella typhimurium strain TA100. The newt micronucleus assay detected a clastogcnic effect on the peripheral blood erythrocytes of Pleumdetes waltl larvae only for 1,3-dichloropropanone and 1,1,3-lrichloropropan-one. Moreover, two structure-activity relationships are noticeable: (1) chloropropanones with chlorinc substituents on both carbon positions (1,3-DCP and 1,1,3-TCP) are by far more genotoxic than chloropropanones substituted only on one carbon position (1,1-DCP and 1,1,1-TCP); (2) the increase of the number of chlorine subslituents decreases the mutagenic activity (fluctuation test) of the chlorinated propanones studied.
