采用COD比色管测定水样COD,石墨炉原子吸收光谱法测定水样中的镉含量,参照国标法进行镉对鱼类毒性试验。试验结果表明:镉对鲩鱼、鲫鱼、鲶鱼三类鱼的中毒剂量分别为0.005mg/L,0.0055mg/L、0.0065mg/L,安全浓度分别为0.005mg/L,0.007mg/L、0.008mg/L。
採用COD比色管測定水樣COD,石墨爐原子吸收光譜法測定水樣中的鎘含量,參照國標法進行鎘對魚類毒性試驗。試驗結果錶明:鎘對鯇魚、鯽魚、鯰魚三類魚的中毒劑量分彆為0.005mg/L,0.0055mg/L、0.0065mg/L,安全濃度分彆為0.005mg/L,0.007mg/L、0.008mg/L。
