This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC50 values of the respective heavy metals and the susceptibility of fish.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC50 values of the respective heavy metals were studied.
📊
Key Findings & Data:The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC50 values were 1.0, 6.5 and 300.0, ppm, respectively.
💡
Conclusion & Impact:This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC50 values of the respective heavy metals and the susceptibility of fish.

Abstract

The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC50 values of the respective heavy metals were studied. The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC50 values were 1.0, 6.5 and 300.0, ppm, respectively. The general accumulation order of heavy metals and their respective 96-h LC50 values were Hg< Cd< Pb. It was observed that the fish with lowest body concentration of heavy metal showed the lowest 96-h LC50 value of the respective heavy metal and vice versa. This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC50 values of the respective heavy metals and the susceptibility of fish.
