Marine fog inputs appear to increase methylmercury bioaccumulation in a coastal terrestrial food web. But barely considered during the long deliberations, according to those involved in the treaty process, was the harm that mercury inflicts on wildlife. Unfortunately, the mercury in fish also concentrates in the tissue of any human or wildlife eating the fish.
