Mercury pollution in the ocean this goal. Proper disposal of mercury containing items such as medicinal packaging and thermometers, using mercury-free bulbs and batteries, buying consumer products with zero or minimum mercury emission to the environment can make a significant difference in recovering world’s ecosystems from mercury pollution leaving minimum legacy of mercury pollution in the ocean for our future generations. Mercury pollution in the ocean Mercury is a toxic heavy metal which cycles through atmosphere, water, and soil in various forms to different parts of the world. Due to this natural cycle, irrespective of which part of the world releases mercury it could affect
Cadmium telluride photovoltaics in Mexico and Sweden. In 1984 astrophysicists identified tellurium as the universe's most abundant element having an atomic number over 40. Certain undersea ridges are rich in tellurium. The manufacture of a CdTe cell includes a thin coating with cadmium chloride () to increase the cell's overall efficiency. Cadmium chloride is toxic, relatively expensive and highly soluble in water, posing a potential environmental threat during manufacture. In 2014 research discovered that abundant and harmless magnesium chloride () performs as well as cadmium chloride. This research may lead to cheaper and safer CdTe cells. By themselves, cadmium and tellurium are toxic
