"pollutant concentrations" is a correct and usable phrase in written English.
It refers to the levels or amounts of pollutants present in a particular environment or substance. Example: The factory's emissions have caused high pollutant concentrations in the nearby river, resulting in the death of aquatic life.
Air pollution epidemiologic studies use ambient pollutant concentrations as surrogates of personal exposure.
Pollutant concentrations near to the exit portals of road tunnels are often much higher than those alongside surface roads.
The pollutant concentrations are different in different merchandise sections.
Spatial distributions of pollutant concentrations are known in priori.
Meanwhile, in regions exposed to reduced precipitation or snowmelt, water shortages may lead to heightened pollutant concentrations in remaining flows.
Examples include structural reliability, wind speed/flood distributions, pollutant concentrations, surveys and models of vehicle arrivals and other independent events.
The literature has been mixed on whether roadside vegetation reduces nearby pollutant concentrations or whether this feature has no effect or even potentially increases downwind air pollutant concentrations.
National meteorological, air-quality and environmental service providers should calculate health and air-quality indices based on pollutant concentrations, similar to those used in North America and Europe.
Influences of sampling time on pollutant concentrations were investigated as well, which indicates that the increases of sampling time reduce the pollutant concentrations to some extent.
Air pollutant concentrations are addressed as numerical values.
Then the pollutant concentrations decreased, and reached stable values finally (Wang, 2004).
