Abstract [English]

Air pollution has become one of the most serious environmental issues that have an impact on human health and ecosystem stability. This paper revolves around observing and explaining the ambience of the major pollutants like PM₂.₅, PM₁₀, SO₂, NO₂, CO and O₃, in some urban and semi urban locations within the Bilaspur district. The sources used to gather data varied between various sites during a set amount of time. The concentrations were examined by standardised approach documented by IS, APHA and CPCB. A variety of instruments which include analytical balances, spectrophotometers, atomic absorption spectrometers and gas chromatographs were used in order to get accurate assessment. The research aids in defining areas of local pollution as well as determining whether the allowable levels are being adhered to and this finally leads to improved air quality management policies.
