Radon is harmful to health and increases the risk of lung cancer. It is a radioactive, colorless, odorless, and tasteless noble gas. Scientists and medical experts have studied radon to understand its effects on health.
All types of asbestos fibers can cause serious health problems in people. The most common illnesses linked to long-term exposure to asbestos are asbestosis and mesothelioma. Amosite and crocidolite are the most dangerous types of asbestos fibers.
Benzene is an organic chemical with the molecular formula C₆H₆. The benzene molecule has six carbon atoms arranged in a flat, six-sided ring, with one hydrogen atom attached to each carbon. Since it contains only carbon and hydrogen atoms, benzene is a hydrocarbon.
Carbon monoxide poisoning happens when people breathe in too much carbon monoxide (CO). Symptoms are often similar to the flu and may include headache, dizziness, weakness, vomiting, chest pain, and confusion. Very high levels of CO can cause loss of consciousness, irregular heartbeats, seizures, or death.
Sulfur dioxide, also known as sulphur dioxide in some regions, is a chemical compound with the formula SO₂. It is a colorless gas with a strong, sharp smell, similar to the scent of burnt matches. This gas is naturally released during volcanic eruptions and is also created as a by-product during processes like refining metals and burning fuels that contain sulfur.
Nitrogen dioxide poisoning is a health condition caused by breathing in nitrogen dioxide (NO₂) gas beyond safe levels. This gas is reddish-brown and has a strong, unpleasant smell at high concentrations. At lower concentrations, it may be colorless but still has a harsh odor.
Particulate matter (PM), also called particulates, refers to tiny solid or liquid particles that float in the air. An aerosol is a mix of these particles and air, but it is different from the particulate matter itself. Particulate matter can come from natural sources or human activities.
Air pollution happens when harmful substances are in the air. These substances can be gases, such as ozone or nitrogen oxides, or tiny particles like soot and dust. Both outdoor and indoor air can be polluted.
Sentinel-5 Precursor (Sentinel-5P) is an Earth observation satellite created by ESA as part of the Copernicus Programme. It was launched in October 2017 and is built to last for 7 years. The satellite uses the TROPOspheric Monitoring Instrument (Tropomi), which helps track methane emissions in great detail.
