What are the manifestations of occupational poisoning?

Poisoning caused by exposure to productive poisons is called occupational poisoning. Acute poisoning may be caused by large amounts of toxic substances once or a short period of time. Chronic poisoning can be caused by long-term excessive exposure to poisons. Short - term exposure to higher concentrations of toxins can cause subacute poisoning. Due to different characteristics of toxicant action, some poisons only cause chronic poisoning under production conditions, such as lead and manganese poisoning. Some toxins can cause acute poisoning such as methane, carbon monoxide and chlorine. Due to the different toxic characteristics of poisons, their performance is quite different, and there are many kinds of poisons.
The nervous system. Chronic intoxication have early common neurasthenia syndrome and mental symptoms, generally functional changes. After disengaging from contact, it can gradually restore. Lead and manganese poisoning can damage motor nerve, sensory nerve, and cause peripheral neuritis. Brain edema can occur in severe poisoning.
Respiratory system. Inhalation of certain gases can cause asphyxia. Long-term inhalation of irritating gases can cause chronic respiratory inflammation, rhinitis, septal perforation, pharyngitis, bronchitis and other upper respiratory inflammation. Inhaling large amounts of irritating gas can cause serious respiratory diseases such as chemical pulmonary edema and pneumonia.
