· Cadmium may produce irritation of the lungs and influenza like symptoms. If cadmium is inhaled, ingested or enters the body, it can accumulate and eventually damage the liver and kidneys. Accumulation of cadmium in the bones may cause a disease called "Itai-Itai" that can make bones brittle leading to fractures. It is also a potential human carcinogen.
· Lead may affect the hematological profile of a person including the central nervous system and inhibits brain function. Exposure may also lead to developmental delays, growth retardation, behavioral effects and learning delays.
· Chromium may cause skin damage and hypersensitivity, nasal mucosa ulceration and nasal septum perforation. Long term exposures may lead to lung cancer.
· Aluminum has been noted to cause impaired memory, dementia and convulsions.
· Magnesium dust and fumes when inhaled may irritate mucous membranes or upper respiratory tract and cause mental fume fever and deterioration of the central nervous system.
· Nitrates, Nitrite, Phosphates and Sulfates may cause dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness and convulsion. Small repeated doses may lead to weakness, general depression, headache and mental impairment. Phosphates may produce an acute effect on the liver and can cause severe eye damage and may eventually affect the central nervous system. Sulfates are skin and mucous membrane irritant and corrosive; it may cause edema of the lungs and can produce respiratory paralysis.
· Carbon Monoxide (colorless, odorless gass) may cause euphoria, headache, eye irritation, narcosis, coma, may be rapidly fatal after formulation leads to anoxia of brain, nervous system and heart.
· Copper dust fumes when inhaled may cause irritation in the respiratory tract.
· Manganese dioxide fumes cause lung irritation, pneumonia, with possible Parkinsonian symptoms, rigidity, muscular pains and tremor.
· Potassium irritation may lead to chemical pneumonitis and pulmonary edema. It may cause severe irritation of upper respiratory tract with cough, burns and breathing difficulty.
· Sodium may cause irritation of the mucous membranes of the nose, throat and respiratory tract.
· Zinc oxide fumes on lungs may cause mental fume fever symptoms like influenza, chills, fever, sweating and muscular weakness.
· Oxides of nitrogen and sulfur may reduce pulmonary function and mucosal irritation. Powerful irritants may cause respiratory damage.
