However, much more metallic mercury is spilled as waste by the chemical industry than is dropped on the floor in the clinic. It is the need to reduce mercury contamination of the environment which should encourage us to cut the usage of metallic mercury. It was this process that led to the Japanese tragedy at Minimata Bay in the late 1950s when over 800 people were poisoned. This can be passed along the food chain and eventually to man. A second danger from metallic mercury is that it is biotransformed into organic mercury, by bacteria at the bottom of lakes. Mercury easily crosses into the brain, and causes tremor, depression, and behavioural disturbances. Dentists are occasionally poisoned this way. It can be vaporised: the vapour pressure at room temperature is about 100 times the safe amount, so poisoning can occur if mercury metal is spilled into crevices or cracks in the floorboards. Organic mercury compounds, which are fat soluble, can cross the blood brain barrier and cause neurological damage. She will be able to tell you if the degree of mercury exposure is a concern, and what to do about it. If you are concerned for your health or your familys as a result of a potential exposure to mercury, get in touch with your health care provider. Inorganic mercury salts are water soluble, irritate the gut, and cause severe kidney damage. The degree of exposure to mercury depends on both the amount and the type of fish eaten. View the Mercury Study Report to Congress EPA has also calculated a reference dose (RfD) level for methylmercury. However, with mercury levels being fairly high in some commercially sold fish, it is possible for a cat to suffer from mercury toxicity after. Mercury is dangerous to both natural ecosystems and. This element is known to bioaccumulate in humans, so bioaccumulation in seafood carries over into human populations, where it can result in mercury poisoning. What does it all mean? There are three forms of mercury from a toxicological point of view: inorganic mercury salts organic mercury compounds and metallic mercury. Volume IV of the report is an assessment of exposure to mercury in the United States. Mercury poisoning in cats is a rare condition. Fish and shellfish concentrate mercury in their bodies, often in the form of methylmercury, a highly toxic organomercury compound. You can be exposed to mercury in a number of ways, and it can be extremely dangerous to your health. Yet you can drink metallic mercury and come to no harm. Mercury poisoning happens as a result of too much exposure to mercury. The new laws have been passed because of worries about mercury poisoning. A ruling by the European Union heralds the demise of those useful clinical instruments, the mercury thermometer and the mercury sphygmomanometer.
