An analysis of the causes effects and prevention of acid rain
However, the dry depositions also known as gaseous particulates in the air which in this case are nitrogen oxides and sulfur dioxide can cause serious health problems when inhaled.
But it gained public attention mainly in s. Regulating the emissions coming from vehicles and buildings is an important step, according to the EPA.
Acid rain causes and effects pdf
The major biological source of sulfur compounds is dimethyl sulfide. Planet Earth Shares Dead trees line a riverbank near Norilsk, Russia, formerly a major industrial center in Siberia, and one of the most polluted cities in the world, according to National Geographic. Acid deposition is anything below that range. Acid rain tendency of altering pH and aluminum concentrations greatly affects pH concentration levels in surface water, thereby affecting fish as well as other aquatic life-forms. The precipitation is not necessarily wet or liquid; the definition includes dust, gasses, rain, snow, fog and hail. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. These acidic pollutants can be washed away from earth surface by rainstorms. The existing winds blow these acidic compounds over large areas across borders and they fall back to the ground in the form of acid rain or other forms of precipitation. Normal rain is slightly acidic, with a pH of 5. During the s, research continued.
Forest damage due to acid rain is most evident in Eastern Europe — especially Germany, Poland and Switzerland. Trees at high altitudes are also susceptible to problems induced by acidic cloud cover as the moisture in the clouds blankets them.
Acid rain effects on plants
Restoring Damaged Environments Use of limestone or lime, a process called liming, is a practice that people can do to repair the damage caused by acid rain to lakes, rivers and brooks. Save energy in homes. Some species can tolerate acidic waters better than others. In the U. It enlarged a network of monitoring sites to determine how acidic the precipitation actually was, and to determine long-term trends, and established a network for dry deposition. There was a decrease in species diversity, an increase in community dominants, and a decrease in the food web complexity. People can also reduce their use of electricity, which is widely created with fossil fuels, or switch to a solar plan. That is a condition that will dissolve rocks," said study team member John Valley. Catalytic converters are fixed on the exhaust pipe system to reduce NOx emission. Acid rain around the world The countries with the highest levels of acid rain are Asian and European countries, particularly Scandinavia and Germany. Normal rain is slightly acidic, with a pH of 5.
Effects of Acid Rain Acid rain has significant effects on the world environment and public health. Subsequent Reports to Congress have documented chemical changes in soil and freshwater ecosystems, nitrogen saturation, decreases in amounts of nutrients in soil, episodic acidification, regional haze, and damage to historical monuments.
Both gases cause environmental and health concerns because they can spread easily via air pollution and acid rain. Most fish species can't survive a water pH of below 5. Acid rain runoff from catchment areas into rivers and lakes has also reduced biodiversity as rivers and lakes become more acidic.
What causes acid rain
Over a period of time, acids get accumulated in the water and lower the overall pH of the water body. As such, man-made acid deposition began becoming a significant issue during the Industrial Revolution and was first discovered by a Scottish chemist Robert Angus Smith in Solutions to acid rain We cannot control volcanic eruptions but we can fight to significantly reduce air pollutants. Presently, large amounts of acid deposition is witnessed in the southeastern Canada, northeastern United States and most of Europe, including portions of Sweden, Norway, and Germany. When the pH level of rain water falls below this range, it becomes acid rain. Irreplaceable damage can be caused to the old heritage buildings. Additionally, alternative energy sources are gaining more prominence and funding is being put toward the restoration of ecosystems damaged by acid rain worldwide. The effects are commonly seen on statues, old grave stones, historic monuments, and damaged buildings. Add alkaline substances to bodies of water to neutralise the pH level. Natural Sources The major natural causal agent for acid rain is volcanic emissions. China is implementing controls for sulfur dioxide emissions, which have fallen 75 percent since —but India's have increased by half.
