THIS chapter presents the subcommittee's review of the evidence of health effects in humans resulting from ingestion of inorganic arsenic. The source of exposure in the large majority of studies reviewed is drinking water contaminated with inorganic arsenic from natural sources.

For most people, diet is the largest source of arsenic exposure, with usually smaller intakes from drinking water and air.

Among foods, some of the highest levels are found in fish and shelfish; however, this arsenic exists primarily as organic compounds, which are. ARSENIC Arsenic was evaluated in the first and third volumes of Drinking Water and Health (National Research Council, a, pp.

;pp. It was also comprehensively evaluated in by another com- mittee (National Research Council, b). Arsenic can cause serious effects of the neurologic, respiratory, hematologic, cardiovascular, gastrointestinal, and other systems.

Arsenic is a carcinogen in multiple organ systems. Interindividual and population differences in arsenic methylation and nutritional status may be factors in susceptibility to arsenic toxicity. Lead and arsenic, for example, are both odorless and tasteless when mixed in with drinking water.

It's a scary thought that carcinogenic chemicals could be lingering in your water supply going undetected until it's too late. The best thing you can do it is to be alert and test your water as often as possible. This review examines and evaluates the literature on the ability of inorganic arsenic compounds to cause cancer in humans and laboratory animals.

The epidemiological data that supports the position that inorganic arsenical derivatives are carcinogenic in humans is convincing and difficult to deny because of their consistency. These data are from studies of different occupational exposures Cited by:   Arsenic in its inorganic form can contaminate water.

Using such contaminated water for drinking, preparation of food and irrigation can pose considerable threats to our health. Arsenic is carcinogenic. Hence, long-term exposure to arsenic through water and food can cause cancer.

Chronic arsenic exposure is a critical public health issue in many countries. The metabolism of arsenic in vivo is complicated because it can be influenced by many factors. In the present meta-analysis, two researchers independently searched electronic databases, including the Cochrane Library, PubMed, Springer, Embase, and China National Knowledge Infrastructure, to analyze factors.

This is the first report of mono- di- and tri-methylated arsenic species in marine interstitial water.A strong positive correlation between the sum of the methylarsenic compounds (MeAs) and the. Arsenic is a chemical element with the symbol As and atomic number Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental c is a has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.

The primary use of arsenic is in alloys of lead (for example, in car Pronunciation: /ˈɑːrsnɪk/, (ARS-nik), as an adjective:. remobilization of historic sources, such as mine drainage water; mobilization into drinking-water from geological deposits by drilling of tube wells.

Drinking-water. Drinking-water poses the greatest threat to public health from arsenic. Inorganic arsenic is naturally present at high levels in the groundwater of a number of countries, such as.

The PHG is a level of drinking water contaminant at which adverse health effects are not expected to occur from a lifetime of exposure. The California Safe Drinking Water Act of (Health and Safety Code Section ), amendedrequires OEHHA to develop PHGs based exclusively on public health considerations.

Exposure to arsenic in contaminated drinking water is generally thought to be more harmful to human health than exposure to arsenic in contaminated foods.

In the past, people were exposed to arsenic during certain medical treatments and through contact with pesticides. Inorganic arsenic compounds were widely used as pesticides until the mid.

Handbook of Arsenic Toxicology presents the latest findings on arsenic, its chemistry, its sources and its acute and chronic effects on the environment and human health.

The book takes readings systematically through the target organs, before detailing current preventative and counter measures. The Society of Environmental Geochemistry and Health (SEGH) Second International Conference on Arsenic Exposure and Health Effects was held Junein San Diego, California.

The conference was at­ tended by people who heard 41 presentations on all aspects of arsenic research. The speakers represented 14 countries.

On the polder, surface water exceeds the World Health Organization drinking water guideline of 10 μg As/L in 78% of shrimp ponds and 27% of rice paddies, raising concerns that produced shrimp and.

Arsenic and its compounds are considered poisonous and elemental arsenic is toxic and labeled as a group 1 carcinogen. Prolonged or heavy exposure can lead to Arsenicosis (Arsenic poisoning) and the development of malignant tumors of skin and lungs, heart disease, cramps, spasms, and effects on nervous system, such as night blindness.

Arsenic in drinking water: This article discusses the detection of arsenic in drinking water, sources of arsenic in water, arsenic exposure limits, and how to remove arsenic from drinking water. Sources of arsenic in drinking water may be from natural occurrence of arsenic in soils and rock, or in some areas from industrial waste.

The form of arsenic determines whether or not it is charged and how soluble it is in water or lipids (fats). Fat-soluble chemicals tend to get across the stomach and intestinal linings, which act as a barrier for many large or charged compounds, and they can sometimes accumulate in tissues with a high fat content until they reach toxic levels.

Arsenic occurs naturally in soil and minerals and may enter the air, water, and land from wind-blown dust and may get into water from runoff and leaching.

• Arsenic cannot be destroyed in the environment. It can only change its form. • Rain and snow remove arsenic dust particles from the air. • Many common arsenic compounds can dissolve.

A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis, the formation of may be due to the ability to damage the genome or to the disruption of cellular metabolic processes.

Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they.

Arsenic health effects include diseases that can affect the cardiovascular system, kidneys, skin, nervous system, or lead to various forms of. Most arsenic in drinking water comes from natural rock formations. As water flows through these formations, it can dissolve arsenic and carry it into underground aquifers, streams, or rivers that may become drinking water supplies.

Arsenic also can come from human activities, such as mining or smelting ores that contain arsenic. Arsenic is a chemical substance, which is released from the Earth’s crust via natural processes and from certain human activities.
