| Abstract: |
| As a kind of emerging contaminants, pharmaceuticals and personal care products(PPCPs) have been gradually concerned by people. PPCPs cause serious adverse effects on aquatic organisms in water because of the residual toxicity in the water environment. The experiment was based on carbamazepine(CBZ) as the target compound, the typical PPCPs compound, which studied the influence of CBZ on the ordinary Chlorella growth, chlorophyll content, superoxide dismutase(SOD) activity, catalase(CAT) activity and malondialdehyde(MDA) content. The concentration of 96 h half maximal effect(EC50) of CBZ on Chlorella vulgaris was 154.42 mg·L-1,which have certain toxicity effects on Chlorella and can inhibit the growth of Chlorella. CBZ affected the chlorophyll content of Chlorella. The low concentration(0.1 mg·L-1) of CBZ act as a disincentive to Chlorella chlorophyll a and chlorophyll b content, which decreased to 2.16 mg·L-1 and 0.38 mg·L-1 respectively. The inhibition gradually weakened with the increasing of CBZ concentration. With the increase of CBZ concentration, the activity of SOD in Chlorella showed inhibition after activation first state, and the activity of CAT showed a low concentration of activated state. The influence of CBZ on MDA content was weak, and the MDA content of processing group was in the range of 2.06 to 2.32 nmol·g-1, which was slightly higher than the control group. The redundancy analysis(RDA) showed that the influence of CBZ on CAT, SOD activity and the content of chlorophyll a were more significant. |
