Acid Rain Can Cause Health Problems in People Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe.
Acid Rain What is Acid Rain? Acid rain is a result of air pollution.
When any type of fuel is burnt, lots of different chemicals are produced. Power stations, factories and cars all burn fuels and therefore they all produce polluting gases.
Some of these gases especially nitrogen oxides and sulphur dioxide react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain".
How acidic is acid rain? Acidity is measured using a scale called the pH scale. This scale goes from 0 to Something with a pH value of 7, we call neutral, this means that it is neither acidic nor alkaline. Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin.
Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6. When the air becomes more polluted with nitrogen oxides and sulphur dioxide the acidity can increase to a pH value of 4.
Some rain has even been recorded as being pH2.
Vinegar has a pH value of 2. The Effects of Acid Rain Acid rain can be carried great distances in the atmosphere, not just between countries but also from continent to continent. The acid can also take the form of snow, mists and dry dusts.
The rain sometimes falls many miles from the source of pollution but wherever it falls it can have a serious effect on soil, trees, buildings and water. Forests all over the world are dying, fish are dying. In Scandinavia there are dead lakes, which are crystal clear and contain no living creatures or plant life.
This leads to fish-eating birds and animals being affected also. Is acid rain responsible for all this?

|Effects of Acid Rain||This type of precipitation can directly kill some organisms, like trees and fish, devastating ecosystems. While acid rain does not affect humans as dramatically, it can indirectly cause health problems, particularly lung issues.|
|Acid Rain and Sulfur-Eating Microbes||Industrial emissions are a major source of gases that cause acid rain, but volcanic eruptions are also a source of these gases. The gases are mainly sulfur dioxide and nitrogen oxides.|
|Forms of Acid Rain||Simply put, it means rain that is acidic in nature due to the presence of certain pollutants in the air due to cars and industrial processes. It is easily defined as rain, fog, sleet or snow that has been made acidic by pollutants in the air as a result of fossil fuel and industrial combustions that mostly emits Nitrogen Oxides NOx and Sulfur Dioxide SO2.|

Scientists have been doing a lot of research into how acid rain affects the environment. Forests It is thought that acid rain can cause trees to grow more slowly or even to die but scientists have found that it is not the only cause.
The same amount of acid rain seems to have more effect in some areas than it does in others. As acid rain falls on a forest it trickles through the leaves of the trees and runs down into the soil below. Some of it finds its way into streams and then on into rivers and lakes.
Some types of soil can help to neutralise the acid - they have what is called a "buffering capacity". Other soils are already slightly acidic and these are particularly susceptible to the effects of acid rain. Acid rain can effect trees in several different ways, it may: A combination of these effects weakens the trees which means that they can be more easily attacked by diseases and insects or injured by bad weather.
It is not just trees that are affected by acid rain, other plants may also suffer. Lakes and Rivers It is in aquatic habitats that the effects of acid rain are most obvious.
Acid rain runs off the land and ends up in streams, lakes and marshes - the rain also falls directly on these areas. As the acidity of a lake increases, the water becomes clearer and the numbers of fish and other water animals decline.
Some species of plant and animal are better able to survive in acidic water than others. Freshwater shrimps, snails, mussels are the most quickly affected by acidification followed by fish such as minnows, salmon and roach.
The roe and fry eggs and young of the fish are the worst affected, the acidity of the water can cause deformity in young fish and can prevent eggs from hatching properly.
The acidity of the water does not just affect species directly, it also causes toxic substances like aluminium to be released into the water from the soil, harming fish and other aquatic animals. Lakes, rivers and marshes each have their own fragile ecosystem with many different species of plants and animals all depending on one another to survive.
If a species of fish disappears, the animals which feed on it will gradually disappear too. If the extinct fish used to feed on a particular species of large insect, that insect population will start to grow, this in turn will affect the smaller insects or plankton on which the larger insect feeds.
Buildings Every type of material will become eroded sooner or later by the effects of the climate.Understanding Acid Rain NEW YORK STATEConservationistNEW YORK STATE. 2 In this issue: Researchers study acid rain to learn about how it affects the environment and people.

Acid Rain and its Harmful Effects. Category: Environment, Essays, Paragraphs and Articles On March 29, By Rahul Kakkar. Introduction to Acid Rain. In simple words, Acid Rain is acid mixed with rain water. Some acidic gases mixed in air, such as sulphur dioxide, some oxides of nitrogen etc.
The harmful effects of Acid Rain includes the. The health effects that people have to worry about are not caused by the acid rain, but are caused when people breathe in these tiny particles or ozone. Swimming in an acidic lake or walking in an acidic puddle is no more harmful to people than swimming or walking in clean water.
Learning About Acid Rain. United States Environmental Protection Agency better understand the science, cause and effect, and regulatory and citizen action that are part of understanding times make people sick. While the “Acid Rain Teacher’s Guide”.
Effects of Acid Rain After studying the Hubbard Brook Forest and other areas, researchers have found several important impacts of acid deposition on both natural and man-made environments.
Aquatic settings are the most clearly impacted by acid deposition .
