Glossary

• Acid RainAcid rain is rain or any other form of precipitation that is much more acidic than normal because of air pollutants like sulfur dioxide and nitrogen oxides. This acidic rain can harm plants, animals, and even buildings. For example, if you notice leaves on trees looking damaged or statues eroding over time in polluted areas, it could be due to acid rain.
• Air PollutionAir pollution happens when harmful substances like gases and tiny particles get into the air, making it unhealthy to breathe and damaging the environment. For example, smoke from factories or cars makes the air dirty and can cause breathing problems.
• Carbon FootprintYour carbon footprint is the total amount of greenhouse gases, especially carbon dioxide, that you release into the atmosphere through your daily activities. It's a way to measure your impact on the environment. For example, every time you drive a car, use electricity, or buy new clothes, you add to your carbon footprint.
• EmissionsEmissions are the gases and particles released into the air, often from vehicles, factories, or burning things. These are what cause air pollution. For example, the fumes coming out of a car's exhaust pipe are emissions.
• Fossil FuelsFossil fuels are natural fuels like coal, oil, and natural gas that formed over millions of years from the remains of ancient plants and animals. When we burn them for energy, they release pollutants and greenhouse gases into the air. For example, the petrol used in cars and the coal burned in power plants are both fossil fuels.
• Greenhouse GasesGreenhouse gases are certain gases in the Earth's atmosphere that trap heat, like a blanket, keeping our planet warm. However, too many of these gases, like carbon dioxide from burning fuels, can trap too much heat and lead to climate change. For example, the carbon dioxide released when you burn wood or drive a car is a greenhouse gas.
• Indoor Air PollutionIndoor air pollution is when the air inside buildings becomes unhealthy due to harmful substances. This can come from things like cooking fumes, cleaning products, mold, or smoke. For example, if a room isn't well-ventilated and someone is burning incense or using strong chemical cleaners, the air quality inside can become poor.
• Particulate Matter (PM)Particulate Matter, or PM, refers to tiny solid or liquid particles floating in the air, like dust, soot, or smoke. These particles are so small they can get deep into your lungs and cause health problems. For example, when you see dust motes dancing in a sunbeam, those are larger forms of particulate matter, but much smaller ones are invisible and more dangerous.
• PollutantA pollutant is any harmful substance that makes the air, water, or land dirty and unsafe. For example, the black smoke coming out of a bus exhaust pipe is a pollutant because it contains harmful gases and particles.
• SmogSmog is a type of air pollution that looks like a hazy, yellowish-brown fog, especially common in cities. It forms when sunlight reacts with pollutants from cars and factories. For example, on a busy winter morning in a big city, you might see a thick, hazy layer over buildings, which is smog.

Where this connects to other fields, and why it's worth knowing.

• Perception & Attention Psychology

  On smoggy days, chess players make worse moves and students score lower on tests. The tiny pollution particles called PM2.5 are small enough to slip from your lungs into your blood and reach your brain. Dirty air isn't just bad for your lungs, it's a hidden tax that quietly makes everyone think a little worse.

• Mental Health Health

  The tiniest specks of air pollution are small enough to cross from your lungs into your bloodstream and reach your brain, and they're now linked to depression and even dementia. That flips how we think about smog: dirty air isn't just a lung problem, it's a mental-health problem too, quietly seeping into your mind.

• Norms, Deviance & Control Sociology

  Violent crime rose, then fell, about 20 years after cities added lead to gasoline and then took it out. Lead is a poison that wrecks self-control in growing brains. So a decision about what we put in the air may have quietly shaped whether a whole generation could stop itself from lashing out.

• Environmental Engineering Technology

  Contaminant measurements inform the design and assessment of air-pollution controls.
