Investigating the effects of accumulation of lead and cadmium metals in fish and its impact on human health

Abstract

The spread of various types of pollution, including heavy metals in water sources, has caused many marine and freshwater ecosystems and their living organisms, especially fish, to be negatively affected. Heavy metals are naturally found in very low concentrations in the water environment, but their concentration has increased due to human activities. Heavy metal poisoning can have many effects on human health and damage the functioning of organs such as the brain, kidneys, lungs, liver, and blood. The toxicity of heavy metals such as lead and cadmium can have acute or chronic effects, since the fishing industry provides part of the food needs of society, the transfer of various pollutants such as heavy metals through the food chain to the human body can be a threat to health.be considered a human society.
