Arsenic: Health Effects and Exposure For example, chickens may have small amounts of inorganic arsenic-containing pesticides added to their feed to prevent infections, which can be transferred to humans through the environment or through the food supply. Drinking water can also contain small amounts of inorganic arsenic. Arsenic can affect every organ.

- These forms can be very poisonous, even in small doses. Don’t take arsenic supplements. Taking 10 mcg/kg/day over a period of time can produce symptoms of arsenic poisoning. Taking 5 mg of arsenic, or sometimes less, can cause digestive tract symptoms. Higher doses can cause severe poisoning and death. Inorganic arsenic is classified as a human cancer-causing agent. Laws have been made to regulate the amount of arsenic that is allowed in the water supply. The maximum permissible level of arsenic in drinking water is 10 mcg/L.

ChemNote: Arsenic Poisoning The Main Advantages that Arsenic-Containing Poisons Offer a Poisoner are: 1  All Arsenic compounds are HIGHLY TOXIC. (The LD50 of Arsenic Trioxide is 16 mg/Kg). 2  Arsenic is very reactive and can interact in many forms. Arsenic can react in acidic media, in basic media and even form fat-soluble organic compounds.

Arsenic Poisoning Symptoms of arsenic poisoning vary with the type and concentration of the poison. Inorganic arsenic may cause abdominal pains, destruction of red blood cells (hemolysis), shock, and death quickly. Lower concentrations of inorganic arsenic and organic arsenic cause far less severe symptoms.

Arsenic poisoning Symptoms of arsenic poisoning begin with headaches, confusion, severe diarrhea, and drowsiness. As the poisoning develops, convulsions and changes in fingernail pigmentation called leukonychia striata, Mees' lines, or Aldrich-Mees' lines may occur.he dominant basis of arsenic poisoning is from ground water that naturally contains high concentrations of arsenic. A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning from drinking water.

Arsenic Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. Arsenic is a metalloid. It can exist in various allotropes, although only the gray form has important use in industry.rsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however. A few species of bacteria are able to use arsenic compounds as respiratory metabolites.

ChemNote: Arsenic Poisoning Arsenic can penetrate into the body through the skin or the lungs but Arsenic mainly enters via drinking water or food that has been eaten. Most Arsenic compounds are soluble in water to some extent and thus are easily transported in the blood stream and assimilated by the body.
