Mercury poisoning: What are the possibly effect??

Mercury is a toxic metal which is widely dispersed in nature. Human activities like coal burning and gold mining are currently the main sources mercury being released to the environment.

In the Journal of Natural Medicine Dr. Nan Fuchs states, “Mercury is considered one of the most toxic substances on earth. Mercury poisoning is as a result of exposure to the toxic metal.Mercury poisoning can equally occur as a result of being exposed to water - soluble forms of mercury (like methylmercury), inhaling mercury vapour, or by ingesting any form of mercury. According to Environmental Protection Agency, the most common way people in the US get exposure to mercury is by consuming fishes containing this health hazardous heavy metal. According to the World Health organization, dental fillings are a larger source of mercury exposure to humans than all other sources combined. Mercury research indicates that mercury spreads through the body within 2 weeks according to the International Academy of Oral Medicine. The risks from mercury in fish and shellfish depend on the amount of fish and shellfish eaten and the levels of mercury in the fish and shellfish. Therefore, the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) are advising women who may become pregnant, pregnant women, nursing mothers, and young children to avoid some types of fish and eat fish and shellfish that are lower in mercury. The scientists, based at the Harvard T.H.

Chan School of Public Health, suspect that prenatal exposure to methylmercury, known to have toxic effects on the developing brain and nervous system, may limit the ability of nervous system tissues to grow and develop. Numerous studies show that high exposure to mercury changes and poisons the nervous system, which can result from irritability, fatigue, behavioral changes, tremors, headache, hearing and cognitive loss, hallucination, and even death. "Mercury exposure can also negatively affect the cardio - vascular system, causing high blood pressure in humans and animals." Faculty of Medicine at the University of Calgary stressed that dental mercury damages brain neurons. Cognitive function improves with aerobic exercise, but not for people exposed to high levels of mercury before birth, according to research funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. “…mercury can adversely affect the immune, urinary, cardiac, respiratory and digestive systems, " the International Academy of Oral Medicine pointed out.
