Abstract:
Beneficial effects on human health by consumption
of omega-3 fatty acids may be challenged by the presence
of heavy metals (HMs) in fish. This study focused on
comparing fatty acid composition (FAC) and HMs
in fish lipids (FL) of twenty-seven fish species (N=2)
from Trincomalee and quantitative estimation of the
risk -benefit. FLs were extracted using Bligh and Dyer
method, whereas FAC and HM (As, Cd, Pb & Hg)
contents were determined by gas chromatography
