As the name implies, ecological field studies are investigations that take place in the actual area under scrutiny, focusing on the site’s habitats and biota1 (resident organisms) and comparing them with unimpacted conditions. Mercury, particularly methylmercury, can accumulate through food webs and generate high risks for species at higher trophic levels.
