Percentage of DNA damage in Carassius auratus kidney cells exposed to 5% and 10% of 96h-LC₅₀ Cr (VI) for four weeks.

Notes: The percentages of DNA damage in control group were 1.4% ± 1.0%, 2.5% ± 1.0%, 1.8% ± 1.0%, and 2.3% ± 1.0%; in 5% of 96h-LC₅₀ exposed fish were 38.2% ± 12.0%, 21.8% ± 8.0%, 15.4% ± 6.0%, and 5.5% ± 3.0%; and in 10% of 96h-LC_50-exposed fish were 40.0% ± 15.0%, 32.8% ± 9.0%, 14.0% ± 6.0%, and 2.4% ± 4.0%, for Weeks 1, 2, 3, and 4, respectively. Both 5% and 10% of 96h-LC₅₀ concentrations induced significantly more DNA damage during the week 1 and 2. Each point represents a mean value and standard deviation of three replicates. *indicates significantly different from the control according to DUNNETT’s multiple comparison test.
