Assessment of Air Quality and Noise Level in Chattogram City, Bangladesh
This study evaluated air quality and noise parameters in the city of Chattogram, Bangladesh. Public health studies are associated with both air pollution and noise pollution in terms of general health consequences due to the severity of pollution, including increased blood pressure, heart disease and other respiratory illnesses. In the urban areas, air pollution and noise pollution from various causes such as transportation, industry and construction activities are gradually and surprisingly increasing. The purpose of this study was to analyze air pollution and noise pollution in 15 different locations classified into industrial, commercial, and institutional areas. The evaluation was carried out for 6 weeks in the dry season. Noise levels, suspended particulate matter (PM2.5, PM10), formaldehyde (HCHO), carbon monoxide (CO), carbon dioxide (CO2), total volatile organic carbon (TVOC), temperature, light, wind velocity, and relative humidity were measured. Measurements were collected in 15 specific locations within Chattogram city for both daytime and nighttime periods during the dry season (November–December 2021). These locations were chosen to represent three distinct types of land use. Average concentrations of PM2.5, PM10, CO, CO2, HCHO and TVOC in the air of Chattogram city are 99, 115 μg/m3, 46, 479, 16 and 1.47 mg/m3, respectively. On the other hand, the noise levels in different locations shows significant variation (55–87 dB). Suspended particulate matter and gaseous pollutants (TVOC, HCHO, CO, CO2) were found in greater concentration during the evening period than the day period respectively. Meteorological parameters (Temperature, Relative Humidity) were found hostile during the day period. The equivalent noise level (Leq) was found to exceed the permissible limit. The maximum average concentration of gaseous pollutants exceeded acceptable limits, which poses environmental and health concerns for local residents. The air quality in those areas was poor and should be monitored on a regular basis. Therefore, regulatory agencies need to enforce environmental standards.
