Is the smell of oil in the working air of Iraqi oil harmful to people?

The smell of petroleum in the harmful air is produced by the gases volatilized from various organic compounds in petroleum, some of which are toxic and irritating, such as benzene, toluene, xylene and aromatic hydrocarbons. Short-term low-concentration contact may cause dizziness, headache, nausea, vomiting and other minor discomfort, but it will not cause serious consequences. Long-term high-concentration exposure may lead to serious harm such as central nervous system injury, abnormal liver and kidney function, suppression of hematopoietic system, respiratory inflammation, skin allergy, and even cancer.
