 Mercury is a major contaminant in the seafood market, and consumption leads to increased risk of cardiovascular disease and cognitive impairments.Decreasing the risk of mercury consumption through global policies to regulate mercury pollution can therefore have a large economic benefit by, for instance, saving individuals the cost of medical care over the course of their lifetime.Another study, also published in 2016, calculated the costs of IQ loss from lead emissions from aviation and won the award for Best Environmental Policy Paper from the journal Environmental Science & Technology.
