Pollutants are high concentrations of toxic chemicals found in the environment. They are generally introduced into the ecosystem through the air, water or soil, and they have the ability to cause great harm to the environment and people’s health.Know More
There are multiple types of pollutants in the environment. Air pollutants are a toxic blend of many different solid particles and gases. This type of pollution is related to a variety of respiratory and reproductive disorders in humans. Carbon monoxide and nitrogen oxide fumes emitted by vehicles are among the main causes of air pollution.
Water pollutants are toxins that build up in lakes, oceans and rivers due to the excessive dumping of toxic waste. Industrial waste disposal and mining activities contribute to water pollution, as does street litter, which can wash into storm drains and waterways, ultimately ending up in the ocean.
Water pollution can cause long-term health problems in humans who regularly consume the water, and wildlife and marine life can die from ongoing exposure to water toxins as well. Watering plants with polluted water is also hazardous to human health. Toxic water can contaminate soil, and plants that are grown in contaminated soil have hazardous substances in their roots. When humans or animals ingest these plants, they can get sick.Learn more about Pollution
Coal mining affects the environment in several ways: underground coal mining introduces toxins such as methane gas into waterways and the atmosphere, and surface coal mining contributes to deforestation and erosion. Coal mining displaces large amounts of water, which in turn alters local water tables. This change affects organisms in surrounding ecosystems, changing the flow rate and volume of water in streams and lakesand impacting the health and growth rates of fish, plants and aquatic species.Full Answer >
The measure of a person's impact on the environment is a simple way to define carbon footprint to children. A more in-depth explanation is that it is the amount of carbon produced by all of a person's activities.Full Answer >
Industrial pollution is the contamination of the environment by businesses, particularly plants and factories, that dump waste products into the air and water. Industrial waste is one of the largest contributors to the global pollution problem endangering people and the environment.Full Answer >
A variety of science fair projects can be done on acid rain, including the effects of acid rain on buildings or the effects of acid rain on the environment. To conduct this type of experiment, acid rain needs to be replicated by combining two tablespoons of vinegar with two cups of water. After the solution is mixed, the pH should be around 4 for the experiment.Full Answer >
