- Heavy metal accumulation across different growth stages of Perna viridis, cultured in a natural habitat and human health risk assessment. Vidyalakshmi, D Yesudas, Aneena Sivan, Gopika Prakash, E Akhil Priyaja, P Metals, Heavy Water Pollutants, Chemical Risk Assessment Animals Environmental Monitoring Humans Perna Ecosystem The green mussel, Perna viridis is renowned for its nutritional profile and as an effective bio-accumulator, making it a valuable indicator of pollution. This study examined the bioaccumulation of heavy metals in P. viridis from spat to adult stage over one year period in a natural mussel bed. Monthly analysis of metals such as Cu, Ni, Mn, Zn, Pb, Cd, Cr, Co, As, and Se was conducted in water, sediment and different body parts (gut, gill, soft tissue, byssus thread and shell) of P. viridis. The impact of monsoonal influence on the uptake of heavy metals and risk assessments were also conducted. Metals like Zn, Cu, Mn, Ni, and Cr were detected throughout the culture period. The concentration of the metals increased from the spat to the adult stage. The gut tissues exhibited the highest concentrations followed by the gills and soft tissues. The shell and byssus thread showed lower concentrations compared to soft tissues. All metals exhibited peak concentrations during the pre-monsoon period, decreased during the monsoon and again increased during the post-monsoon season highlighting a strong seasonal influence. The human risk assessment indicated that the heavy metal concentrations were within safe limits, posing minimal risk of lethal effects.
