Consequences And Effects Of Acid Rain

Introduction

Acid rain is one of the common pollutants that affect some of the country. Acid rain was recovered first by Robert Angus Smith in 1852 in an article called ‘On the air and rain of Manchester’. Acid rain is more acidic due to presents of SO2, CO2 and NOx, when the pH is greater than 5.5, the atmosphere is alkaline. In contrast when pH is below 5.5, the atmosphere is become acidic and tend to fall an acid rain. Acid deposition is a process of air pollutants that can be deposited from the atmosphere to the earth into wet and dry form. Wet deposition is the deposition on surfaces of dissolved substances and particles formed by any form of precipitation. While, dry deposition is the deposition on surfaces of dry gases or particles in the atmosphere. Acid deposition is specifically describes wet form of acid rain that comes from the rain. An acid can be defined as any precipitation that when dissolved in water dissociates to yield corrosive hydrogen ions. It can cause of natural causes which is volcanic eruptions in particular. It is also can effect human activities, such as the burning of fossil fuels. The geographic pattern of acid rain is changing. Industrial countries are showing signs of increased acid rain. In contrast, some of the countries that have traditionally been associated with acid rain are now seeing signs of technology.

Acid deposition consist of both wet and dry(gaseous) precipitation. There are number of phenomena under acid deposition
