Abstract

Brick kiln is a big environmental issue for the agriculture of Bangladesh as it was observed that the agricultural production in the soil close to the brick kiln was lesser than the same soil far from brick kiln. The study was conducted to assess the impact of brick kiln operation to the degradation of topsoil quality at Singair of Kalihati upazila in Tangail, Bangladesh, during the period of July to December 2013. The Soil was collected from areas close to the brick fields and far from the brick fields at a depth of 0-15 cm. The Electrical Conductance (EC) was found almost double in the soil samples close to the brick field than the soil samples far from brick field. The organic mattter content in the soil sample close to the brickfield was significantly lower than that of the far soil sample. The mean values of total N, available P and S were also significantly lower in the soil samples close to the brick kiln, 0.05%, 12.4, and 8.36 ppm respectively in the close soils, while 0.06%, 24.6, and 11.7 ppm respectively in the far soil. There were no significant changes observed in the other elements.

Abstract

With the rate of fast urbanization, the devasting effects of air pollution are spreading across the globe. Due to its connection to people’s health, air quality should be given more importance than other environmental measures. Air pollution is considered a cause of many human diseases. Therefore, this study intends to investigate seasonal variation of air quality and “Air Quality Index (AQI)” in Chittagong city due to its volume, large population density, and importance as a commercial capital city of Bangladesh. Air pollution data on PM10, PM2.5, NO2 , NOx, SOx, CO, and O3 levels have been collected from TV station, Khulshi Continuous Air Monitoring Station (CAMS). Component-specific analyzers have been used to continuously measure trace gases where O3 is observed with a UV photometric analyzer. This study detect the highest peak (PM2.5= 93.5 µg/m3, PM10= 210 µg/m3) in January and the lowest concentrations (PM2.5= 14.6 µg/m3 and PM10= 26.9 µg/m3 ) during July and August. The highest average concentration has been recorded as the value of SO2= 12.8 ppb (monsoon season), NO2= 64.9 ppb (pre-monsoon), CO= 1.2 ppm (monsoon) and lowest SO2= 3.2 ppb (winter season), NO2= 24.4 ppb (monsoon), CO= 0.6 ppm (pre-monsoon) respectively. The AQI values (223.6), (109.5), (194.5), and (317.3) indicate that the air quality during the pre-monsoon, monsoon, post-monsoon, and winter season is very unhealthy, cautious, unhealthy, and extremely unhealthy, respectively.
