Heavy metals: Implications associated to fish consumption

M I Castro-González et al. Environ Toxicol Pharmacol. 2008 Nov.

Abstract

Metals are being utilized of ways in industries and agriculture; particularly heavy metals such as mercury, cadmium, lead and arsenic constitute a significant potential threat to human health because they are associated to many adverse effects on health. The consumption of fish is recommended because it is a good source of omega-3 fatty acids, which have been associated with health benefits due to its cardio-protective effects. However, the content of heavy metals discovered in some fish makes it difficult to establish clearly the role of fish consumption on a healthy diet. Therefore the present mini-review accounts for the recent evidence of the effect of these toxic metals on the human health and their possible implications in fish consumption.
