Abstract

This study examines how cadmium chloride exposure impacts protein content in Lamellidens marginalis across different seasons. Acute toxicity tests (96 h) in monsoon, winter, and summer revealed LC50 values of 8.07, 11.39, and 3.54 mg/L, respectively, with protein levels analyzed in various body parts. Results revealed significant reductions in protein content across all tissues, with the extent of depletion varying by season and duration of exposure. During the monsoon, the protein content showed a non-significant decrease after 24 hours, but this reduction became significant over extended exposure periods, especially in the foot and mantle. In winter, the control group exhibited higher protein levels than in the monsoon, but exposure led to a marked decline, particularly in the gill and hepatopancreas. Summer showed the most significant decreases in protein content, with the gonad and gill being most affected. This study highlights the seasonal variability in cadmium toxicity, emphasizing the importance of considering environmental factors in ecotoxicological assessments

Conclusion

This study demonstrates that cadmium chloride exposure significantly affects the protein content of various body parts in Lamellidens marginalis, with the extent of the impact varying with the seasons and exposure duration. The results indicate that the toxicity of cadmium is exacerbated during the summer season, where higher temperatures likely contribute to increased metabolic stress and greater protein depletion. The findings highlight the critical need for considering seasonal variations when assessing the ecological risks of heavy metal pollution in aquatic environments. Further research is recommended to develop strategies for protecting freshwater ecosystem from metal stress with the help of freshwater bivalve
