Seasonal Dynamics of Heavy Metal Concentrations in Water and Fish from Hakaluki Haor of Bangladesh

Food safety is currently a serious concern due to the health risks associated with food intake, particularly heavy metal contamination. Therefore, present study was conducted investigate metals concentration in water and fishes collected from Hakaluki haor, Bangladesh. Three important fish species, Labeo rohita, Cirrhinus cirrhosis, calbasu, together samples, were analyzed for (Pb, Cr, Cd), respectively. Considering four seasons, namely monsoon, post-monsoon, winter, pre-monsoon, total of 72 samples three fishing stations June 2017 May 2018. The results showed that mean (mg L?1) found be order Pb (0.125 ± 0.058) > Cr (0.026 0.012) Cd (0.001 0.0002) within maximum permissible limits set by EU WHO, except concentrations. Similarly, concentrations (µg g?1) L. rohita (0.388 0.291) cirrhosus (0.334 0.236) calbasu (0.251 0.117) greater than (0.3 µg FIQC, calbasu. However, below FAO quantity contamination this haor indicates situation worrying region’s biota residents. protect public reduce environmental risk, appropriate authorities should oversee monitor it strong hands.
