Effects of Atrazine on the Development of Neural System of Zebrafish, Danio rerio

Figure 4

ATR bidirectionally regulated AChE activity of embryos and larvae exposed to ATR at early embryonic stages. This figure was a trend chart made by the data in Table 1. Before hatching (36 and 48 hpf), the high concentration of ATR could increase the activity of AChE; to the contrary, the activity of AChE was inhibited by the high concentration of ATR after incubation. Figure in the ATR concentration gradient (mg/L): C0, 0 (DMSO); C1, 0.0001; C2, 0.001; C3, 0.01; C4, 0.1; and C5, 1. 30 zebrafish embryos were used for each experimental group (24 hpf, 36 hpf, 48 hpf, and 72 hpf).
