Irritation mercury exposure

Acrodynia, a rare Idiosyncratic reaction to chronic mercury exposure, occurs mainly In children and has the following features pain In the extremities, often accompanied by pinkish discoloration and desquamation ( pink disease ) hypertension profuse sweating anorexia. Insomnia, Irritability, and/or apathy and a mlllarial rash. 

Air-poUutant effects on neural and sensory functions in humans vary widely. Odorous pollutants cause only minor annoyance yet, if persistent, they can lead to irritation, emotional upset, anorexia, and mental depression. Carbon monoxide can cause death secondary to the depression of the respiratory centers of the central nervous system. Short of death, repeated and prolonged exposure to carbon monoxide can alter sensory protection, temporal perception, and higher mental functions. Lipid-soluble aerosols can enter the body and be absorbed in the lipids of the central nervous system. Once there, their effects may persist long after the initial contact has been removed. Examples of agents of long-term chronic effects are organic phosphate pesticides and aerosols carrying the metals lead, mercury, and cadmium. 

Toxicity. Coball, like most oilier metals, is not entirely harmless, although ii is not in any way comparable lo the known toxic metals, such as mercury, cadmium, and lead. Inhalation of fine cobalt dust over long periods can cause an irritation of Ihe respiratory organs, which may result in chronic bronchitis. Complete recovery is usually achieved upon removal from the contaminated atmosphere. Cobalt salts can cause benign dermatoses, either in people new to handling them, or aflci prolonged exposure, usually several years. 

Mercury Fulminate Poisoning has symptoms of mercury poisoning. At low levels causes dermatitis and irritation of the mucous membranes Avoid all routes of exposure. Tolerance level below 0.01 mg/m3... 

Percutaneous exposures can occur either directly through the skin or through injuries to the skin. Some chemicals in gaseous or liquid form (such as methyl mercury or cyanide) can be absorbed directly through the skin. Materials that are soluble in skin perspiration can also be absorbed. Reactions of gases, solids, and liquids with the skin can lead to problems ranging from skin irritation to allergic reactions, and to chemical burns (Sullivan et al., 2001). 

Observe normal precautions appropriate to the circumstances and quantity of material handled. Phenylmercuric acetate may be irritant to the skin, eyes, and mucous membranes. Eye protection, gloves, and a respirator are recommended. Chronic exposure via any route can lead to central nervous system damage. In the UK, the occupational exposure limit for mercury-containing compounds, calculated as mercury, is 0.01 mg/m long-term (8-hour TWA) and 0.03 mg/m shortterm. ... 

Upon significant inhalation exposure to metallic mercury vapors, some people (primarily children) may exhibit a syndrome known as acrodynia, or pink disease. Acrodynia is often characterized by severe leg cramps irritability and erythema and subsequent peeling of the hands, nose, and soles of the feet. 

The observed effects include red and burning eyes, conjunctivitis (Bluhm et al. 1992a Foulds et al. 1987 Karpathios et al. 1991 Schwartz et al. 1992 Sexton et al. 1976), and a yellow haze on the lenses of the eye (Atkinson 1943 Bidstrup et al. 1951 Locket and Nazroo 1952). The yellow haze was associated with long-term occupational exposures. Animal studies were not available to support these findings. However, the evidence suggests that exposure to high levels of mercury vapor may result in ocular irritation.
