In recent years, Hg release into the environment has increased due to human activities. Burning industrial or domestic wastes containing mercury, for instance, causes mercury emissions in the atmosphere. Another possible source is the mining industry, which can contaminate rivers and soils.
Once released into the environment, mercury is accumulated in some marine species, such as fish and other marine invertibrates, in the form of methyl mercury. Further to the damage caused to these species, from there mercury is then introduced into the food chain, causing problems for other animals and/or humans.
