Methaemoglobinemia is characterized by reduced ability of the blood to carry oxygen because of reduced levels of normal haemoglobin. In the body nitrates are converted to nitrites. The nitrites react with haemoglobin in the red blood cells to form methaemoglobin. Infants are most often affected, and show signs of blueness around the mouth, hands, and feet, hence the common name blue baby syndrome. These children may also have trouble breathing as well as vomiting and diarrhoea.
Coal workers' pneumoconiosis, also known as black lung disease is caused by long exposure to coal dust. It is a common in coal miners and others who work with coal.
