High levels of pollution and haze were seen in the city from 6 to 11 November. Researchers at DU and JNU have reported that there was also a high concentration of mist, PM1.0, due to air humidity and humidity in winter. This type of particulate matter is harmful but sufficient mechanisms are not available in Delhi-NCR to study it.
SK Dhaka of Rajdhani College, University of Delhi, and AP Dimari of the School of Environmental Sciences at Jawaharlal Nehru University found that PM1.0 particles emerged at high densities of up to 250–280 micrograms / m3 over six days.
Such observations are not made by regular measurements of the Delhi Pollution Control Committee and CPCB. The high value of PM1.0 is an urgent issue because it can enter the bloodstream through the lungs and would be dangerous to health. Dhaka asserted that we require to analyze fine-grained data to furnish accurate information about seasonal variability, especially on sub-micron rules, as per DU and JNU report.
Researchers used data at the Dwarka location and examined through the use of purple air sensors – compact and smart pieces of equipment, which furnish data with high exactness and on fine scales in the range of 1 micron.
Dhaka further added, We also wielded the important optical smart sensor as CUPI (Compact and Useful PM2.5 Instrument) formulated by Nagoya University, Japan, and Panasonic. Dhaka said that both detectors showed PM2.5 to be considerably higher, touching 1,000 μm g / m3.
Researchers, nonetheless, contend that the high value of PM1.0 examined during 6–1 November should scrutiny many in medical terms. Such data is not usable in Delhi-NCR, and we need more comments to help medical doctors with our studies, Dhaka said.
