ACID RAIN

by Ezekiel Peay

WHAT IS ACID RAIN

Acid rain is rain that has been made acidic by certain pollutants in the air

CAUSES

1. Acid rain is causes by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air

2. Also acid rain is caused by reactions in the environment. Normal precipitation such as rain, sleet, hail, and snow react with alkaline chemical(non-acidic) which usually neutralizes natural acids however if precipitation becomes to acidic, the materials may not be able to neutralize all the acids.

What are the effects

Acid rain:

1. Harms forests

Acid rain seeps into the ground and can dissolve nutrients like magnesium and calcium that trees need to be healthy

2.Causes ground level ozone

This leads to respiratory problems, like pneumonia and bronchitis

3.Creates acidic clouds and fog

This strips important nutrients from trees and makes it easier for them to get infections, insects, and cold weather damage killing the natural forest

4.Causes aluminum to be released

This makes it difficult for the trees to take up water a vital nutrient

5. Causes lakes and streams to have a lower ph level.

normal lake sand streams have a PH level of about 6.5

6. Damages buildings and objects

Erodes, strips and discolors objects making them appear to be old and reduces their value

How are we reducing this problem

1.Pollution reducing devices such as scrubbers are being made to clean the gases going into the air.

2. Low sulfur coal is being used and coal is washed to remove the sulfur.
