ABSTRACT

 

Jodhpur, founded in 1459 by Rao Jodha, is the second largest city of Rajasthan today and has more than 6 lakh registered vehicles and more than 20000 registered industries. Growth in population, industrial and urban activities have resulted in deterioration of air quality. Keeping the above fact in mind the present study was undertaken to quantify particulate matter PM10 and suspended particulate matter (SPM) in different environmental backdrops of Jodhpur. Samples were collected using Respirable dust sampler (Envirotech instruments) model APM460BL, at 8hr cycle monthly from July 2017 to November 2017 belonging to commercial (Shastri Circle) and industrial area (Basni Phase I). Highest PM10 was recorded at Shastri Circle site 150.15?gm/m3 in October 2017 and lowest was observed 73.09?gm/m3 in August 2017. Highest PM10 recorded at Basni Phase I site was 234.74?gm/m3 in September 2017 and lowest was observed 168.58?gm/m3 in November 2017. The SPM was highest 502.23?gm/m3 at Shastri Circle site in September 2017 and lowest was recorded 167.71?gm/m3 at the same site in July 2017. At Basni Phase I site highest SPM recorded was 1045.6 ?gm/m3 in July 2017, while lowest was recorded in October 2017 being 393.08 ?gm/m3. The above findings are nowhere near the Revised National Ambient Air Quality Standards (NAAQS) 2009 given by CPCB, pointing towards the gravity of the situation. Hence there is dire need to take adequate measures otherwise we may land in the situation Delhi is facing today.
