DETERMINATION OF HEAVY METAL IN FRESH WATER FISH

DETERMINATION OF HEAVY METAL IN FRESH WATER FISH

INTRODUCTION

Heavy metals are any metals that are clinically undesirable and pose a potential hazard. Heavy metals in the aquatic environment are a serious problem due to their toxicity to animal life, which disrupts the normal ecological balance (Bhattachary et al., 2008). Excessive concentrations of heavy metals in aquatic ecosystems. Load has become a widespread issue that affects individual existence in an environment (Voegborlo et al, 1999). Toxic heavy metals in the aquatic environment can be traced back to both natural and anthropogenic sources. Anthropogenic activities in the aquatic ecosystem have impacted the aquatic habitat and fish, which are a crucial component of the food chain that leads to humans (Mason, 1996).

Chains of heavy metals and chemical molecules can bioaccumulate. Heavy metals are conservative pollutants in the sense that they degrade over such a lengthy time period that they practically form a permanent contribution to the aquatic ecosystem (Mason, 1996).

Heavy metals in fresh water were discovered to be absorbed over the gill surface or via the gat was well tract.
