The most common air pollutants include carbon monoxide, ground level ozone, nitrogen oxides, particulate matter, sulfur oxides, and volatile organic compounds. There are other pollutants that are important both due to their impact on the environment and on public health. We will take a look at two such pollutants, ammonia and hydrogen sulfide.

Monitoring the composition of ambient air is a vital process in maintaining the quality of the air we breathe. The World Health Organisation (WHO) has attributed millions of deaths per year to air pollution and inhalation of industrial particulates emitted by vehicles and industrial plants. New research has underlined the severity of the issue, suggesting that the health impacts associated with polluted air are more severe than previously believed. The European Heart Journal estimates that air pollution reduces the mean life expectancy in Europe by approximately 2.2 years.
Ambient air quality testing is conducted to determine the gaseous or particulate concentration of air that may be released into the environment or breathed by humans. Dry air in the Earth’s atmosphere comprises a dynamic mixture of gases, primarily nitrogen (~78%) and oxygen (~21%). Smaller volumes of argon (~0.9%) and carbon dioxide (~0.04%) are alsoRead More
