Internal combustion engine the atmosphere by the reaction of and volatile organic compounds in the presence of sunlight. Ground-level ozone is harmful to human health and the environment. Though the same chemical substance, ground-level ozone should not be confused with stratospheric ozone, or the ozone layer, which protects the earth from harmful ultraviolet rays. Carbon fuels contain sulfur and impurities that eventually produce sulfur monoxides (SO) and sulfur dioxide (SO) in the exhaust, which promotes acid rain. In the United States, nitrogen oxides, PM, carbon monoxide, sulphur dioxide, and ozone, are regulated as criteria air pollutants under the Clean Air Act to levels
Nitrogen dioxide poisoning in etiopathogenesis of endometriosis, a disease in which tissue that normally grows inside the uterus grows outside the uterus. Oxidative stress causes defective placentation which is likely to lead to placental hypoxia, shortage of oxygen in the placental as well as reperfusion injury resulting from ischemia which may lead to endothelial cell dysfunction. Over-expression of oxidative stress caused by nitrogen dioxide poisoning may results in ovarian epithelium inflammation and sometime leads to cancer in severe cases. Nitrogen dioxide poisoning Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (). It usually occurs after the inhalation
