Abstract<\/b><\/span><\/span>
Levels of copper (Cu), zinc (Zn), led (Pb), cadmium (Cd) and chromium (Cr) were determined in the waters of a fish farm in Mymensingh district, Bangladesh by Atomic Absorption Spectrophotometer. Metals were found to be present in varied concentrations: Cu (0.02-0.1 mg\/L), Zn (0.055-0.072 mg\/L), Pb (0.039-0.066 mg\/L), Cd (0.014-0.29 mg\/L) and Cr (0.13-0.23 mg\/L). The results signify that levels of Cd slightly exceeded and Cr in water was almost 1 order of magnitude higher than the values stated by ADB (Asian Development Bank, 1994); EPA (Environment Protection Agency, 2002); WHO (World Health Organisation, 1993); WPCL (Water Pollution Control Legislation, 2004) and USPH (United State Public Health). In general, the rank order of heavy metals was Cr > Pb > Cu > Zn > Cd. This suggests that water of the investigated fish ponds is contaminated with metals and in turn, fish of that aquaculture farm could be harmful to human health.<\/span>
