| genotoxicological response of the common carp (cyprinus carpio) exposed to spring water in tlaxcala, méxico. | this study evaluated the genotoxic impact of anthropic activities in huactzinco spring, using cyprinus carpio as a biomonitor. in situ and in vivo experimental designs were compared by means of simultaneous 2-week exposures. the water from the spring generated mean micronuclei frequency values (108.6 ± 32 mn/1,000) and dna fragmentation values (143.4 ± 35 au) which were statistically higher than those for the negative control (10.9 ± 6 mn/1,000 and 67.6 ± 23 au). the in situ and in vivo experime ... | 2014 | 24950945 |
