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.read more

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.

Bioaccumulation of non-essential hazardous heavy metals and metalloids in freshwater fish. Risk to human health
Hazrat Ali,Ezzat Khan +1 more
TL;DR: In this article, the authors present possible routes for uptake of heavy metals and metalloids in fish, and present various indices used to assess risk to human health, such as metal pollution index, health risk index, target hazard quotient and hazard index.

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.

Health risk from heavy metals via consumption of food crops in the vicinity of Dabaoshan mine, South China.
TL;DR: Estimated daily intake (EDI) and THQs for Cd and Pb of rice and vegetables exceeded the FAO/WHO permissible limit and bio-accumulation factors of heavy metals were significantly higher for leafy than for non-leafy vegetable.

TL;DR: In the last decade, a new pattern of Hg pollution has been discerned, mostly in Scandinavia and North America, mostly due to more widespread air pollution and long-range transport of pollutants.

TL;DR: EPA's Integrated Risk Information System (IRIS) is a human health assessment program that evaluates information on health effects that may result from exposure to environmental contaminants.

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.
