Indoor Air Pollution and Bio-monitoring Device

The air is primarily polluted due to anthropogenic sources like combustion, sewage and waste disposal, mining, agricultural practices (use of pesticides, fungicides, fertilizers etc.) and vehicular wear and tear. All of these generated pollutants include heavy metals, NO2, CO, SO2 and SO3 etc. These pollutants disrupt the structure of the ecosystem, endanger the health of people and animals and cause plant diseases. The use of bio-monitors, make it simple to study important primary data about diversity, as they are able to detect the quantity and quality of pollutants. Many organisms are used to monitoring air pollution as bio-indicators. Lichen is an excellent bio-indicator for monitoring air pollution. This study investigates the use of lichens as bio-indicator and bio-monitor of air pollution. No chemical testing is necessary in this procedure; the air quality is ascertained solely by physical examination (the size and color intensity of lichens). The monitoring kit makes it simple to measure the indoor air quality. It is important to take preventative steps to keep individuals healthy, especially the elderly and children.
