Acid rain Acid rain Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1970s to reduce the release of sulphur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulphur dioxide
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
