Scientists generally speculate that one-third of the sulfur and nitrogen emissions in the United States comes from these natural sources (this is a rough estimate as there is no way to measure natural emissions as opposed to those that are manmade.) The primary anthropogenic (human-caused) contributors to acid rain are SO emissions by source from 1983 to 2002.
Although these are still significant causes, scientists have come to believe that airborne nitrates account for one-fourth of all nitrogen, the second most prevalent cause after fertilizers. Geological Survey (USGS), ammonium levels in precipitation increased throughout the 1990s across most of the country. Several factors contribute to the impact of acid rain on an area.
Scientists also blame ammonia emissions, which come largely from agricultural activities such as manure handling and fertilizing, for contributing to acid rain. Transport systems—primarily the movement of air—distribute acid emissions in definite patterns around the planet.
Whatever its form, acid rain can create dangerously high levels of acidic impurities in water, soil, and plants.
The acidity of any solution is measured on a potential hydrogen (p H) scale numbered from zero to 14, with a p H value of seven considered neutral.
