HighlightsHeavy metal levels in fish feedstuffs, fish and also in organs of fish-treated Swiss albino mice were studied.For Cu and Pb, the mean values in the feed sample were lower than the respective maximum tolerable value.Some elements for example Cr, Zn and in different parts of the A. testudineus fish samples exceeded the respective limits.The highest level of Cr was observed in most of the fish samples, Cr and Pb were found above their respective threshold limits in the liver.
This study was designed to examine the effect of commercially available poultry feedstuff on the broiler, subsequently, its impact on the experimental animal. The proximate composition as well as concentrations of Pb, Ni, Mn, As and Zn in broiler feed and meat were determined using energy dispersive X-ray fluorescence (EDXRF) spectrometry. Higher levels of Cr, Mn, Zn, Cu, Ni were observed in broiler feed, broiler meat and in the liver of the experimental mice Swiss albino treated with BB1 and BB2. The concentration of these (Cr, Pb and As) metal were 0.182, 0.18, 0.163 µg/g and 0.233, 0.08, 0.158 µg/g, respectively. The blood cholesterol and LDL were significantly higher in the broiler meat treated experimental mice. Remarkable degeneration observed in the liver and kidney of broiler meat-treated mice. It is concluded that although broiler has nutritional benefits the quality of this meat may be compromised as a consequence of contamination through various anthropogenic activities and the presence of toxic metals in commercial poultry feed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
