An overview of causes effects and cost of acid rain on the environment

  • The more acid that is introduced to the ecosystem, the more aluminum is released;
  • If something harms one part of an ecosystem — one species of plant or animal, the soil or the water — it can have an impact on everything else.

Human Health The Effects of Acid Rain on Ecosystems This figure illustrates the pH level at which key organisms may be lost as their environment becomes more acidic. Not all fish, shellfish, or the insects that they eat can tolerate the same amount of acid.

An ecosystem is a community of plants, animals and other organisms along with their environment including the air, water and soil.

Effects of Acid Rain

Everything in an ecosystem is connected. If something harms one part of an ecosystem — one species of plant or animal, the soil or the water — it can have an impact on everything else. Effects of Acid Rain on Fish and Wildlife The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife.

ADDITIONAL MEDIA

As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released. Some types of plants and animals are able to tolerate acidic waters and moderate amounts of aluminum.

Others, however, are acid-sensitive and will be lost as the pH declines. Generally, the young of most species are more sensitive to environmental conditions than adults.

At pH 5, most fish eggs cannot hatch. At lower pH levels, some adult fish die. Some acidic lakes have no fish.

  1. At pH 5, most fish eggs cannot hatch.
  2. Even if a species of fish or animal can tolerate moderately acidic water, the animals or plants it eats might not. Acid rain also contains nitrogen, and this can have an impact on some ecosystems.
  3. Everything in an ecosystem is connected. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere.

Even if a species of fish or animal can tolerate moderately acidic water, the animals or plants it eats might not. For example, frogs have a critical pH around 4, but the mayflies they eat are more sensitive and may not survive pH below 5.

Effects of Acid Rain on Plants and Trees Dead or dying trees are a common sight in areas effected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

  • Even if a species of fish or animal can tolerate moderately acidic water, the animals or plants it eats might not.

The trees are then less able to absorb sunlight, which makes them weak and less able to withstand freezing temperatures.

This capacity depends on the thickness and composition of the soil and the type of bedrock underneath it. In areas such as mountainous parts of the Northeast United States, the soil is thin and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.

Episodic Acidification Melting snow and heavy rain downpours can result in what is known as episodic acidification.

This short duration of higher acidity i. Acid rain also contains nitrogen, and this can have an impact on some ecosystems.

For example, nitrogen pollution in our coastal waters is partially responsible for declining fish and shellfish populations in some areas. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere.
