PPT-If we test to see if terrestrial organisms or aquatic organisms have more mercury then

methylation Methylation is how mercury changes into organic forms and this happens under water Introduction The information our group researched is important because it tells us whether terrestrial or aquatic organisms have more mercury Mercury can also kill many people According to the EPA mercury can be found in air water and soil Mercury is everywhere and it gets there by emissions from vehicles and emissions from factories but the main ways are through .
