What are the factors that cause pollution?
Additionally, environmental pollution is triggered by the introduction of harmful materials, such as gaseous pollutants, toxic metals, and particulate matter (PM) into the atmosphere; sewage, industrial effluents, agricultural runoffs, and electronic wastes into water bodies; and activities such as mining.
What are the main factors that cause air pollution?
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires.
What are the causes of human pollution answer?
1) Burning of fossil fuels: Sulfur dioxide released by the burning of fossil fuels like coal, petroleum is the major cause of air pollution. Gases emitted from vehicles including trucks, jeeps, cars, trains, aeroplanes cause an immense amount of pollution.
What is water pollution and its causes and effects?
Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.
What is water pollution explain its causes and effects?
Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste, petroleum, and disease-causing microorganisms.
What are the effects of pollution?
Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Humans are also regularly harmed by pollution. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases.
What is water pollution and its effects?
EFFECTS OF WATER POLLUTION In addition, here are some of the other consequences: Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —. Contamination of the food chain.
What are the harmful effects of water pollution?
Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health. Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain.
What are the harmful effects of water pollution class 9?
Question 6 What are the harmful effects of water pollution?…Human diseases: Pathogens(viruses,bacteria,fungi,protozoa etc)are biological pollutants of water. Removal of desirable substance from water bodies: Effects of thermal pollution or change in temperature: Destruction of useful microorganism:
How does pollution affect human health?
The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. Microscopic pollutants in the air can slip past our body’s defences, penetrating deep into our respiratory and circulatory system, damaging our lungs, heart and brain.
What is water pollution and its control?
Control of water pollution requires appropriate infrastructure and management plans. The infrastructure may include wastewater treatment plants. Sewage treatment plants and industrial wastewater treatment plants are usually required to protect water bodies from untreated wastewater.
What are the causes effects and prevention of water pollution?
Industries also cause thermal pollution by discharging hot water into water bodies such as lakes, rivers and even into the sea. It increases the temperature of the water and adversely affects the stability of the ecosystem. You may know that the solubility of oxygen decreases with the increase of temperature.
What are the controls of pollution?
Specific means of pollution control might include refuse disposal systems such as sanitary landfills, emission control systems for automobiles, sedimentation tanks in sewerage systems, the electrostatic precipitation of impurities from industrial gas, or the practice of recycling.
How can we prevent pollution?
On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:Reduce the number of trips you take in your car.Reduce or eliminate fireplace and wood stove use.Avoid burning leaves, trash, and other materials.Avoid using gas-powered lawn and garden equipment.
