Ecological risk assessment of heavy metals in sediment and human health risk assessment of heavy metals in fishes in the middle and lower reaches of the Yangtze River basin

Distribution and bioaccumulation of heavy metals in aquatic organisms of different trophic levels and potential health risk assessment from Taihu lake, China.

Studies on seasonal pollution of heavy metals in water, sediment, fish and oyster from the Meiliang Bay of Taihu Lake in China

In the present study, 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. The results showed that the Cr, Cu, Cd and Pb content in the edible parts of the two fish species were much lower than Chinese Food Health Criterion (1994). However, the results showed marked differences in the four analyzed metal content between the two species and different tissues as well as significant variations. Pb content were the highest in the liver of fishes, Cd contents were almost the same in all organs of fishes, Cr contents mainly enriched in the kidney and liver, Cu contents were the highest in gills, However, the total metal bioaccumulation were greatest in the liver, gills and the lowest in the muscle. Although the total accumulations were highest in P. fluvidraco compare then C.carpio. This investigation indicated that fish products in Meiliang Bay, Taihu Lake were still safe for human consumption, but the amount consumed should be controlled under the Chinese Food Health Criterion to avoid excessive intake of Pb. Further, this is the first report on seasonal distribution of heavy metals and proximate compositions of commercialized important edible fishes from Meiliang Bay, Taihu Lake, China.

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

Assessment of heavy metals in tilapia fish (Oreochromis niloticus) from the Langat River and Engineering Lake in Bangi, Malaysia, and evaluation of the health risk from tilapia consumption.

Cr， Zn， Cu， Cd， Pb 内容在 Cyprinus carpio Linnaeus， Carassius auratus Linnaeus， Hypophthalmichthys molitrix 和 Aristichthys nobilis 被决定，它从 Meiliang 海湾被抓住，泰胡·莱克，中国的一个大、浅、发育营养正常促进剂的湖。结果显示出那：(1 ) Cr， Cu， Pb，在四鱼种的可食的部分的 Cd 内容比中国食物健康低得多标准(1994 ) ，而是 Zn 内容比标准高；( 2 ) Cd 内容在鱼的肝是最高的， Pb 内容是几乎在鱼的所有机关的一样，主要在皮肤和性腺充实的 Cr 内容， Zn 内容在性腺是最高的(♀)，并且 Cu 内容在肝是最高的；(3 ) 全部的金属累积在肝是最大的并且在肌肉最低。全部的金属累积在 C 是最高的。auratus L。这调查显示在泰胡·莱克的鱼产品为人的消费仍然是安全的，但是消费的数量应该在中国食物健康标准下面被控制避免 Zn 的过多的吸入。
