Table 2. DNA damage in Daphnia magna in response to phosmet.

	Damage frequency (%)	Arbitrary unit (AU)	Genetic damage index (GDI)
Control	37.33 ± 0.88a	75.00 ± 6.65a	0.75 ± 0.06a
0.01 µM	53.33 ± 0.87b	127.33 ± 3.17b	1.27 ± 0.03b
0.1 µM	63.67 ± 0.81c	140.00 ± 2.64b	1.40 ± 0.02b
p value	***	***	***

Notes:

DF, Damage frequency; AU, Arbitrary Units; GDI, Genetic Damage Index (mean value ± sd). The differences between groups were considered statistically significant if the p value was <0.05.

^***p < 0.001

Groups with different letters are significantly different from each other.
