Heavy Metal Poisoning :: essays research papers fc

levelheaded Metal PoisoningHeavy metal drunkenness is the toxic accumulation of reasoned metals in the low-key tissues of the body. Heavy metals are chemical elements that have a specific solemness at least five times that of water. The heavy metals most much implicated in human poisoning are lead, mercury, ratsbane, and cadmium. Some heavy metals, such as zinc, copper, chromium, iron, and manganese, are required by the body in small amounts, but these same elements can be toxic in larger quantities.Heavy metals may enter the body in food, water, or air, or by absorption through the skin. Once in the body, they manage with and displace essential minerals such as zinc, copper, magnesium, and calcium, and interfere with organ strategy functions. People may come into contact with heavy metals in industrial work, pharmaceutical manufacturing, and agriculture. Its even possible that children can be poisoned as a result of playing in contaminated soil.     Hea vy metal poisoning may be detected using blood and urine tests, sensory vibrissa and tissue analysis, or x dicks. In childhood, blood lead levels higher up 80 g/dL generally indicate lead poisoning, however, significantly lower levels (>30 g/dL) can cause mental deceleration and other cognitive and behavioral problems in affected children. The Centers for Disease get word and Prevention considers a blood lead level of 10 g/dL or higher in children a cause for concern. In adults, symptoms of lead poisoning are usually seen when blood lead levels fall 80 g/dL for a number of weeks. Another weighty factor is that blood levels containing mercury should not exceed 3.6 g/dL, age urine levels should not exceed 15 g/dL. Symptoms of mercury poisoning may be seen when mercury levels exceed 20 g/dL in blood and 60 g/dL in urine. An elicit way to test for the amount of mercury in someones system, is to test hair a follicle, and record the levels of mercury in order to gauge the co gency of chronic mercury exposure. Furthermore, arsenic is rapidly cleared from the blood. Blood arsenic levels may not be very useful in diagnosis. arsenic in the urine (measured in a 24-hour collection following 48 hours without eating seafood) may exceed 50 g/dL in people with arsenic poisoning. If acute arsenic poisoning is suspected, an x ray may reveal ingested arsenic in the abdomen. It is visible because the arsenic appears whole on an x-ray. Arsenic may also be detected in the hair and nails for months following exposure.
