Air Pollution: Learn to talk like a scientist about it. (1) Air pollution: let’s analyse, clean, and deliver. (1) Can living walls reduce air pollution? BBC News investigates at Middlesex University. National Clean Air Day 2020 – National Awareness Days Events Calendar 2020 – UK & US. The World Health Organisation and the UK Government recognise that air pollution is the largest environmental health risk we face today.
It causes heart and lung diseases, is linked to low birth weight and children’s lung development and may even contribute to mental health issues. Every year, air pollution causes up to 36,000 deaths in the UK. Clean Air Day is the UK’s largest air pollution campaign, engaging thousands of people at hundreds of events, and reaching millions more through the media. Clean Air Day normally takes place on the third Thursday in June. This year, due to COVID-19, Clean Air Day is taking place on 8 October 2020. Coordinated by Global Action Plan, Clean Air Day brings together communities, businesses, education and the health sector: (1) Six ways to reduce air pollution. What Causes Air Pollution? The Short Answer: 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. The solid and liquid particles suspended in our air are called aerosols. Credit: NASA/JPL-Caltech Air pollution happens when solid and liquid particles—called aerosols—and certain gases end up in our air. Where do aerosols come from? Any particle that gets picked up into the air or is formed from chemical reactions in the air can be an aerosol. Aerosols can come from other places, too, such as ash from an erupting volcano. This animation uses NASA data to show how ash from a volcano in Chile travels around the world in our atmosphere.
Air Pollution. How Do We Cause Air Pollution?
We cause air pollution directly through our use of electricity, fuels, and transportation. We also cause air pollution indirectly, when we buy goods and services that use energy in their production and delivery. Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result. Using carbon dioxide as an example, the average family in the United States causes air pollution in the following ways: Air pollution - A simple introduction to its causes and effects.

Last updated: November 17, 2018. Photo: Air pollution is obvious when it pours from a smokestack (chimney), but it's not always so easy to spot. This is an old photo of the kind of smoke that used to come from coal-fired power plants and, apart from soot (unburned carbon particles), its pollutants include sulfur dioxide and the greenhouse gas carbon dioxide. Thanks to tougher pollution controls, modern power plants produce only a fraction as much pollution. Toxic Vehicle Emissions Lead To Four Million Asthma Cases in Children Every Year. Children in huge number i.e. about four million every year are developing asthma from air pollution caused by vehicles like cars and trucks.
A landmark study also disclosed that it is equivalent to 11,000 new asthma cases every day occurring worldwide because of toxic air from traffic. The places with pollution levels below the limit set by the World Health Organization are witnessing most of the new cases which mean toxic air is even more harmful than we thought. Children health is deteriorating not only in countries with high pollution levels like China and India but the traffic pollution is also the reason of one-quarter of all new childhood asthma cases in UK and US cities as per the researchers.
Out of the 194 nations analyzed to examine the rate of new traffic-related asthma cases, Canada ranked third highest. The Los Angeles and New York City are in the list of top 10 worst cities out of the assessment of 125 cities. Arindom Ghosh Latest posts by Arindom Ghosh (see all) Sources and Effects of Six Common Air Pollutants. Air pollution is a growing problem around the world, with individuals and nations alike pumping enormous volumes of harmful pollutants into the atmosphere every day.
These pollutants are not only dangerous to the health and wellbeing of plants, animals, and people, but they are also a major contributor to recent climate shifts observed across the globe. Cutting down on the volume of pollutants produced is a crucial step in managing our negative effect on the climate. How can this be achieved? National Geographic. Causes, Effects and Solutions of Air Pollution. Pollution is now a common place term, that our ears are attuned to.
We hear about the various forms of pollution and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals and humans to survive as the air becomes dirty. Save Smog City 2! - Smog City 2.
