Weathering release occurs of Ca and other ions into surface waters. Rainfall is acidic because atmospheric carbon dioxide dissolves in the rainwater producing weak carbonic acid. In unpolluted environments, the rainfall pH is around 5.6. Acid rain occurs when gases such as sulfur dioxide and nitrogen oxides are present in the atmosphere. These oxides react in the rain water to produce stronger acids and can lower the pH to 4.5 or even 3.0. Sulfur dioxide, SO, comes from volcanic eruptions or from fossil fuels, can become sulfuric acid within rainwater, which can cause solution weathering to the rocks on which it
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
