Measurement of Air Concentrations of Particulate Matters, Volatile Organic Compounds and Formaldehyde in Lahore

Abstract

Background and Objective:The volatile organic compounds (VOCs) including formaldehyde (HCHO) are widely concerned due to their harmful impact on human health by productionof photochemical smog and ozone and have great impacton air quality. High air pollution level in urban areas is one of the major concerns therefore, there is need to develop cost-effective devices for measurement of VOCs in the environment. The objective of the study was to quantify the levels of these hazardous chemicals in air in major areas of Lahore.Methods: This study was a cross-sectional descriptive study. A new multi-item pollution monitoring device (Life Basis DM 106 A) was used to carry out the readings. The areas targeted were busy areas of Lahore including Jail Road,

Integrating Passive Biomonitoring and Active Monitoring: Spider Web Silk and Portable Instruments for Air Quality in Urban Areas

“…The Data Darbar in Lahore had the highest levels of volatile organic compounds (VOCs) at 10 mg/m 3 and formaldehyde (HCHO) at 0.99 mg/m 3 , whilst the G.O.R-1 location had the lowest values at 0.004 mg/m 3 and 0.002 mg/m 3 , respectively. There was a strong positive correlation between PM 1.0 and PM 10 , although PM 2.5 also showed a strong negative correlation with relative humidity in the area (p = 0.009) which has been reported by Aslam et al (2020) in urban areas of Lahore. TVOCs are priority atmospheric pollutants because of their adverse impacts on human health and many of the VOCs are humanmade chemicals.…”

“…Indoor sources of TVOCs Paint, paint strippers, Varnishes and finishes, Caulks and sealants, Adhesives, Flooring, carpet, and pressed wood products while outdoor potential origins of this pollutant encompass Gasoline, diesel emissions, wood burning, oil and gas extraction and processing (ALA, 2023), which is very unfortunate that this type of economic strengthens indicator process have lower ratio in Pakistan. Harmless air is defined as having a total VOC level of less than 100g/m3 (Aslam et al, 2020).…”

Critical Review and Comparative Analysis of the Government of Punjab’s ‘Policy on Controlling Smog, 2017’ with Counterpart Strategies in London, Beijing and Los Angeles

“…The major primary and secondary air pollutants in excess across Punjab that demand monitoring include NOx, SOx, PM10, PM2.5, CO and VOCs (Aslam et al, 2020;Colbeck et al, 2010;Haider et al, 2017;Hamid et al, 2019). The Government of Punjab should monitor and report data on the aforementioned pollutants to help inform policy development and track progress on pollution control efforts.…”
