Fossil fuel percent of [its] weighted emissions in 1998. Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulfur dioxide, volatile organic compounds and heavy metals. According to Environment Canada: "The electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit
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
