Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body. If arsenic poisoning occurs over a brief period of time symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and : Arsenic. Arsenic is toxic to both plants and animals and inorganic arsenicals are proven carcinogens in humans. The toxicity of arsenic to human health ranges from skin lesions to cancer of the brain, liver, kidney, and stomach (Smith et al., ). A wide range of arsenic toxicity has been determined that depends on arsenic speciation.

Arsenic (As) is found in waters such as seawater, warm springs, groundwater, rivers, and lakes. In aquatic environments, As occurs as a mixture of arsenate and arsenite, with arsenate usually predominating. The unrestricted application of As pesticides, industrial activities, and mining operations has led to the global occurrence of soluble As above permissible levels of mg/L. Continuous. This table contains the most up to date criteria for aquatic life ambient water quality criteria. Aquatic life criteria for toxic chemicals are the highest concentration of specific pollutants or parameters in water that are not expected to pose a significant risk to the majority of species in a given environment or a narrative description of the desired conditions of a water body being "free.   Arsenic poisoning, or arsenicosis, occurs after the ingestion or inhalation of high levels of arsenic. Arsenic is a type of carcinogen that’s gray, silver, or white in color. Arsenic Toxicity: Prevention and Treatment reviews current understanding of arsenic poisoning and the health consequences resulting from exposure. The book paints a vivid picture of the sources of arsenic toxicity including ground water; food such as rice, fruits and vegetables, fish, and chicken as well as occupational exposures from.

  Various aquatic plants have been identified as an efficient arsenic accumulator like Eichhornia crassipesm, Lemna minor, and Spirodela polyrrhiza which may be exploited in removing arsenic from contaminated water individually and by developing a plant-based treatment system. Similarly, arsenic accumulator algal species may be utilized for. pentavalent species. Arsenic may be absorbed by ingestion, inhalation, or through permeation of skin or mucous membranes; cells take up arsenic through an active transport system normally used in phosphate transport. The mechanisms of arsenic toxicity differ greatly among chemical species, although all appear to cause similar signs of poisoning. The Canadian water quality guidelines for arsenic for the protection of aquatic life were developed based on the CCME protocol (CCME ). For more information, see the supporting documents (CCME ; Fletcher et al. ). Freshwater Life Data on the toxicity of arsenic to freshwater biota were available for 21 species of fish, 14 species of.
