Arsenic is a naturally occurring element widely distributed in the earth’s crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.
Breathing high levels of inorganic arsenic can give you a sore throat or irritated lungs.
Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of “pins and needles” in hands and feet.
Ingesting or breathing low levels of inorganic arsenic for a long time can cause a darkening of the skin and the appearance of small “corns” or “warts” on the palms, soles, and torso.

Associated with various types of cancer such as skin and liver, the intake of arsenic it is also linked to cardiovascular disease and diabetes. According to a long-term research conducted by experts from the Center for Research and Advanced Studies it was determined that this metalloid inhibits enzymes associated with antioxidant protection.
Arsenic poisoning is widespread in Bangladesh, where ground water is contaminated by runoff from the Himalayas.

New evidence indicating that EPA should lower its safe fluoride level goal in public drinking water systems to zero, will be presented by former EPA senior risk assessment scientist, William Hirzy PhD, at the Fluoride Action Network's (FAN) 5th Citizens' Conference and Lobby Day on Fluoride, September 5 – 8, at the Crystal City Hyatt Regency Hotel in Crystal City, VA. A press conference on September 5 will provide a preview (details below).
Inorganic arsenic in rice and rice-based foods poses health concerns in infants and young children, and steps should be taken to minimize exposure, according to a commentary in the Journal of Pediatric Gastroenterology and Nutrition, official journal of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.
Mice exposed to low doses of arsenic in drinking water, similar to what some people might consume, developed lung cancer, researchers at the National Institutes of Health have found.
Infant toenails are a reliable way to estimate arsenic exposure before birth, a Dartmouth College study shows. The findings appear in the Journal of Exposure Science & Environmental Epidemiology. A PDF of the study is available on request.
United Nations University will help pioneer a fresh trail in global health research, exploring links between the planet's health and human health at an institute in Kuala Lumpur generously supported by Malaysia.
The National Science Foundation has awarded nearly $200,000 to two University of Texas at Arlington researchers teaming with a private company to make an affordable, environmentally friendly field analyzer for arsenic levels in water.
Individuals with dyspnea, or shortness of breath, have an increased long-term mortality risk compared with individuals without dyspnea, according to a new study presented at the 2014 American Thoracic Society International Conference.

We know that babies and young children often put non-food items in their mouths, a behaviour that occasionally leads to swallowing of foreign objects. Metallic toys and low-cost jewelry often contain toxic substances such as lead and cadmium.
Researchers at the Prairie Research Institute's Illinois Natural History Survey have found that overall, concentrations of arsenic, selenium, and mercury in bighead and silver carp from the lower Illinois River do not appear to be a health concern for a majority of human consumers.
Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive.
