Segmentation Analysis

By Pollutant

Chemical Segment to Dominate Market Due to Rising Need for Systems to Identify and Quantify Various Harmful Chemicals

Based on the pollutant, the market is classified into chemical, physical, and biological.

The chemical segment is anticipated to dominate the outdoor air quality monitoring system market share. The growth of the segment can be linked to the rising need for systems that can identify and quantify various harmful chemicals present in the air. These pollutants can lead to significant health problems. Government and environmental organizations enforce stringent regulations to oversee and manage air quality. This regulatory pressure and heightened public awareness regarding the health risks associated with air pollution are encouraging both public and private entities to invest in sophisticated air quality monitoring systems to detect chemical pollutants.

Physical pollutants, mainly Particulate Matter (PM), specifically PM2.5 and PM10, are minuscule particles or droplets that can be breathed in and result in significant health problems, including respiratory infections, heart disease, and lung cancer. The growth of urbanization and industrial activities has resulted in elevated levels of these pollutants, particularly in heavily populated cities. As a result, there is an increased need for air quality monitoring systems that can detect and quantify the presence of particulate matter.
