In a study by Han et al, the effects of PM<2.5 micrometers on life history traits and oxidative stress were observed in Tigriopus japonicus. Exposure to particulate matter of less than 2.5 micrometers in diameter led to significant changes in ROS levels, indicating that particulate matter exposure was a causative agent of oxidative stress in ...
In addition, exposure to fine particulate matter (PM2.5) from fossil fuel combustion is associated with respiratory diseases, cardiovascular diseases, and premature mortality. A 2021 study estimated that fossil fuel-related air pollution is responsible for over 10 million premature deaths annually worldwide. [58]
A study by the European Environment Agency estimates that 307,000 people have died prematurely in 2019 due to fine particle pollution in the 27 EU member states. [213] A study in 2000 conducted in the U.S. explored how fine particulate matter may be more harmful than coarse particulate matter. The study was based on six different cities.
Environmental indicator criteria and frameworks have been used to help in their selection and presentation. It can be considered, for example, that there are major subsets of environmental indicators in-line with the Pressure-State-Response model developed by the OECD. One subset of environmental indicators is the collection of ecological indicators which can include physical, biological and ...
(For example, calculation of the ozone AQI requires computation of an 8-hour average and computation of the PM 2.5 or PM 10 AQI requires a 24-hour average.) To accurately reflect the current air quality, the multi-hour average used for the AQI computation should be centered on the current time, but as concentrations of future hours are unknown ...
Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges .

Biomarkers of exposure assessment is a measure of the contaminant or other proportionally related variable in the body. [8] Air sampling measures the contaminant in the air as concentration units of ppmv (parts per million by volume), mg/m 3 (milligrams per cubic meter) or other mass per unit volume of air. Samplers can be worn by workers or ...
Contingent valuation surveys were first proposed in theory by S.V. Ciriacy-Wantrup (1947) as a method for eliciting market valuation of a non-market good.The first practical application of the technique was in 1963 when Robert K. Davis used surveys to estimate the value hunters and tourists placed on a particular wilderness area.
