Heavy Metal Bioaccumulation and Health Hazard Assessment for Three Fish Species from Nansi Lake, China

TLDR
Health hazard assessment showed no health risk from exposure to Pb, As, Cd, and Hg by consuming fish from this lake, but Hg concentration was higher, suggesting that heavy metal pollution problem in fish from Nansi Lake still exists.
Abstract
Metal accumulation in fish is a global public health concern, because the consumption of contaminated fish accounts for the primary exposure of humans to toxic metals. In this study, the concentrations of arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in Crucian carp (Carassius auratus),Yellow catfish (Pelteobagrus fulvidraco), and Bighead carp (Hypophthalmichthys nobilis) from Nansi Lake of China were evaluated, and compared with the corresponding historical values in 2001 when the government started to govern water environment effectively. Bioaccumulation of heavy metal was highest in P.fulvidraco, followed by C.auratus and H.nobilis. The concentrations of Pb, As, Cd were much lower than the historical values, but Hg concentration was higher, suggesting that heavy metal pollution problem in fish from Nansi Lake still exists. Health hazard assessment showed no health risk from exposure to Pb, As, Cd, and Hg by consuming fish from this lake.

Bioaccumulation of heavy metals in fish species from the Meiliang Bay, Taihu Lake, China

TL;DR: In this paper, the bioaccumulation of heavy metals (Cr, Cu, Cd, Pb) content were determined in freshwater edible fishes Cyprinus carpio Linnaeus and Pelteobagrus fluvidraco, which were caught from the Meiliang Bay, Taihu Lake, a large, shallow and eutrophic lake of China.

Studies on biomarkers of oxidative stress and associated genotoxicity and histopathology in Channa punctatus from heavy metal polluted canal

TL;DR: It can be concluded that the sugar mill effluent has the potential to cause oxidative stress, DNA damage and histopathology in C. punctatus exposed to effluents and the consumers may suffer adverse health effects like that in indicator organism.

- 01 Nov 2000 - 
TL;DR: The results of this study indicated that a general absence of serious pollution in the Atatürk Dam Lake is due to heavy metals, where as the concentrations of elements found could mainly be attributed to geological sources.
