sb amounts of arsenic may enter the body through the skin, but this is not usually an important consideration. Most arsenic that is absorbed into the body is converted by the liver to a less-toxic form that is efficiently excreted in the urine. Consequently, arsenic does not have a strong tendency to accumulate in the body except at high exposure levels. 4- The OSHA PEL is listed as 0.01 mg/m' for inorganic forms of arsenic and O.S ---} mg/m' for organic forms. 4- The CaVOSHA PEL is listed as 0.01 mg/m' for inorganic forms of arsenic and 0.2 mg/m' for organic forms. } m4 The TLV is listed as 0.01 mg/m' for arsenic and inorganic arsenic compounds. -' Inorganic arsenic has been recognized as a human poison since ancient times, and large doses can produce death. Lower levels of exposure may produce injury in a number of rt different body tissues or systems [i.e., systemic effects]. When taken by mouth, a common effect is irritation of the digestive tract, leading to pain, nausea, vomiting, and diarrhea. Other effects include decreased production of red and white blood cells, abnormal heart function, blood vessel damage, liver and/or kidney injury, and impaired nerve function causing a "pins-and-needles" feeling in the feet and hands. Inhalation exposure to inorganic arsenic dusts or fumes sometimes produces a pattern of skin abnormalities including the appearance of dark and light spots on the skin, and small --} ..corns" on the palms, soles and trunk. Some of these corns may ultimately progress to skin cancer. In addition, arsenic ingestion has been reported to increase the risk of cancer inside the body, especially in the liver, bladder, kidney and lung. However, of much grater concern is the ability of inhaled arsenic to increase the risk of lung cancer. ' Direct dermal contact with arsenic compounds, frequently from inorganic arsenic dusts > in air, may result in mild to severe irritation of the skin, eyes, or throat. WARNING: Arsenic is known to the State of California to cause cancer. - WARNING: Arsenic is known to the State of California to cause birth defects or J other reproductive harm. Cadmium Cadmium is a bluish-white metal used in electroplating, in nickel-cadmuim storage batteries, as a coating for other metals, in bearing and low-melting alloys, and as control rods in nuclear reactors. Cadmium compounds have numerous applications, including dyeing and printing textiles, as TV phosphors, as pigments and enamels, and J in semiconductors and solar cells. There are several reports of cadmium poisoning _a and human death. Cadmium can enter the body in inhalation of its dusts or fumes, or by ingestion. In humans the acute toxic symptoms are nausea, vomiting, diarrhea, _j headache, abdominal pain, muscular ache, salivation and shock. In addition, inhalation of its fumes or dusts can cause cough, tightness of chest, respiratory distress, sb Environmental Services,LLC© October,2003 California Integrated Waste Management Board - Site Specific Health and Safety Plan Page 11 of 62 Tracy Tire Fire Remediation Project J,
