Indoor Air Quality Monitoring in College Campus.

Abstract

The study characterizes the exposure of a typical gaseous co-pollutant like carbon dioxide, carbon monoxide, on students with in college campus, under various microenvironments in Bangalore city. By the aid of Standalone Air Quality Monitor, monitoring was done to determine the concentration of the gases such as CO2, CO. Furthermore, health analysis of the monitoring survey area and comparison of the result with prescribed standards available were also carried out to determine the various ill-health effects caused by it. The results showed during the real time monitoring period, the measurements carried out in different microenvironments were quite stable and hardly any major variation was found, except those at the college canteen and chemistry laboratory. The peak values of CO2 determined in canteen (kitchen) and computer laboratory (without A.C) were reported higher than found in any other microenvironment. The concentration of CO2 and CO in college canteen (kitchen) were found to be exceeding the standards by almost twofold. Health survey conducted revealed problems like headache, dizziness, respiratory discomfort, confusion etc. due to elevated gaseous concentration in various microenvironments can prove to be a promising human health risk assessment measure based on the relative time spent in a particular environment
