Particulate matter (PM) comprises solid and liquid particles in the air. PM10 particles have a diameter less than 10 micrometres. Coarse particles (2.5–10 micrometres) can be inhaled – they generally deposit in the upper airways; fine particles (smaller than 2.5 micrometres) can deposit deep in the lungs where air-gas exchange occurs.

Since PM10 is small enough to be inhaled, exposure can cause cardiovascular and respiratory health problems, such as heart attack, stroke, lung cancer, and premature death. It can also aggravate asthma and has been linked with diabetes. Children, the elderly, and people with existing heart or lung issues have a higher risk of health problems from exposure to PM10. These problems include decreased lung function, heart attack, and mortality.

This dataset reports on the annual trends assessed for the period 2011-2020.

Ground-level (tropospheric) ozone (O3) exists at a natural background level but is also produced when nitrogen oxides (NOx) and volatile organic compounds from vehicle emissions, petrol fumes, industrial processes solvents, and other human-made sources react in the presence of heat and sunlight. It is the primary component of photochemical smog. Ozone also occurs naturally in the stratosphere, where it protects us from ultraviolet radiation – this ozone occasionally can mix downwards to ground level.

Ozone is a colourless, odourless gas. Exposure to high concentrations of ozone can cause respiratory health problems and is linked to cardiovascular health problems and increased mortality. Those most at risk include people with asthma, children, older adults, and people who are active outdoors, such as outdoor workers. People with certain genetic characteristics and nutrient deficiencies are also at greater risk from ozone exposure. Ozone can also affect sensitive vegetation and ecosystems and can cause damage during the growing season.
