Indore: Figures compiled by MP Pollution Control Board (MPPCB) regional office, Indore suggest that presence of respirable suspended particulate (RSPM) in the ambience of Indore has increased by 50% of the permissible limit. The MPPCB collects samples from three locations; Vijay Nagar, Kothari Market and Sanwer Road and of these places, Kothari Market has the highest presence of RSPM.
The presence of this pollutant was 145, 121 and 211 µg/meter3 from January to March in Vijay Nagar area, while the same was 171, 186 and 193 µg/m3 in Kothari Market and 133, 160 and 181 µ g/m3 in Sanwer Road in the same period. The permissible limit of RSPM in the air is 100 µg/m3.
RSPM mainly comprises dust particles of less than 10 microns which can enter the body and cause several respiratory ailments.
“Growing network of cement concrete roads, never ending construction activities and reducing roadside plantation is mostly responsible for higher presence of RSPM in the ambience in the city,” said MPPCB chief chemist Aparna Baapt.
Apart from construction activities, the large number vehicles have aided in the increase of RSPM in the city’s ambience, claimed a scientist from MPPCB Indore who didn’t want not to be named.
The RSPM is small amounts can lead to ailments in lungs, eyes and heart and if the concentration is more, it can enter the blood and cause serious troubles, claimed the scientist. The MPPCB experts however claim that presence of other pollutants like SO2 and NO2 is not so alarming in the city.
