Acid Rain effects on Eco-System

A very bad effect is appeared in the Eco-system because of acid rain. Most of the time Eco- systems turn to one way. Some bad effects are highlighting below:

1. Fish and water Eco-system are affected by Acidic River, Canals, and ponds. So, it’s reducing hatching and the genetic power of fish.
2. Acid Rain reduces the pH of water. It’s causing the abstraction of food chain and destructing the water system. Acid Rain creating a big problem for water system by making a lot of organic stuff in water.
3. Density tolerable limits of heavy metals are crossed due to acid rain.
4. Mostly soils become damage, due to acid rain. If the pH rates of soil decrease, the growth rates of soil also decrease. A lot of necessary micro bacteria and components get dead due to acid rain. So the productive lands become unproductive.
5. Water forests are damage due to acid rain. Water forest are decreasing very fast, it's only because of acid rain. Due to acid rain tree leafs and synthesizes are obstructing.
6. Due to acid rain man’s skin appear to be changed. Acid rain also create problem with environment.

What is Acid Rain?

Acid Rain is a highlighting cause behind endangered Global warming. When the rate of pH in rain water is 1.8-5.5 then its call Acid Rain. The normal rate of pH in rain water is 5.6-6.2; if the rate of acid in the Precipitations like rain, dew and fogs are much so it's call acid rain.

Rain water is also some kind of acid. That contain a little of amount of carbon-dioxide, after mixing with water it make very weak acid like Carbonic Acid.

 With the dissociation of carbonic acid produce H+ and its make rain water slice acid.

  

If the rate of Precipitations is less then 5.0 pH, its call Acid Rain.

Acid Rain is not something new; it was first appeared at 1800Ac in UK. Till 1960 there was no occurrence of acid rain.  But after 1960 many places in the world facing this natural calamity. Now it's occurring frequently in many countries and destructing the balance environment.

So Acid Rain is also playingrole to increase Global warming and it's too threatening our existence.

Causes behind the Acid Rain

Nature and man made things is responsible for acid in rain water. Acid in rain water produce because of the present of Sulfuric and Nitric Acid. Both of that secondary air polluter produces from primary air polluter sulfur-dioxide and Nitrogen Oxide.

Sulfur-dioxide and Nitrogen Oxide thrown from the source, spread way to a vast area. Sulfur-dioxide and Nitrogen Oxide produce Sulfuric; Nitrous and Nitric acid with the touch of vapor. Acid Rain is the mixer of those gases. Sulfur-dioxide, Sulfur-Trioxide and NO2 produce acid with the react of vapor and its call acid rain.

Relevantly Sulfur-dioxide produces from the burning of patrol, metal and sulfur extraction from mineral. On the other hand the source of Nitrogen Oxide is old vehicles, power plant, metal extraction centers and so on.

Naturally acid rain spread thousands of kilometers away. The main reason behind the Global warming is CFC and green house gas and the destruction of ozone layer is known as global air pollution. When air is polluted by acid rain it's know as regional air pollution. Some other example of regional air pollution is polluting by burning, burning of woods, flying ashes, smoke and nuclear precipitation.
