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
Exposure assessment and 'exposure analysis' are often used as synonyms in many practical contexts. Risk is a function of exposure and hazard. For example, even for an extremely toxic (high hazard) substance, the risk of an adverse outcome is unlikely if exposures are near zero. Conversely, a moderately toxic substance may present substantial risk if an individual or a population is highly exposed. Quantitative measures of exposure are used: in risk assessment, together with inputs from toxicology, to determine risk from substances released to the environment, to establish protective standards, in epidemiology, to distinguish between exposed and control groups, and to protect
