Ranchi: People in the big cities of Jharkhand suffer from allergies, runny nose and irritation in the respiratory tract but do not understand the reason.
Medical experts are also not in a position to formally link it with air pollution without scientific data.
The monitor of the air quality index (AQI) monitor near Van Bhavan in Ranchi recorded the PM10 level at 143.61 and PM2.5 at 84.84 on Wednesday around 4pm.
Under medical standards, Aqi in the range of 100-149 is considered unhealthy when classified as very unhealthy in the range of 150-249 followed by “dangerous” in the range 250 and above.
In contrast to the levels recorded on the AQI monitor from the Jharkhand pollution control board, private institutions that monitor level-level to all parameters at a very high level.
According to Accuweather who gathered information from French-based earring laboratories, monitored air quality regularly, Ranchi recorded AQI 215 on Wednesday, categorized “very unhealthy”.
PM2.5 In 191, it was also poor while NOx (nitrogen oxide) and basic level ozone were found in a fair category in the range of 45 and 36 each.
Aqi in Jamshedpur was recorded in 207, while in Bokaro and Dhanbad respectively 193 and 184.
In all four cities, material particulates both in the PM10 category and PM 2.5 are at the temporary level of carbon monoxide levels in the “very good” category.
Ashish Sheetal, Secretary General of Yugantar Bharti, an NGO working in the field of environmental conservation, said the difference in the AQI level was mainly due to the installation of unscientific monitoring equipment.
“Aqi depends on the air samples monitored.
We recommend three monitors placed in triangles to monitor the air from a certain area so that large air samples are monitored instead of a single monitor that can skip real samples if the wind blows from the monitor,” he said.
Asked what explains lower levels of Sox, NOx and Co, mostly associated with vehicle and industrial pollutants but many PM10 and PM2.5 pollutants in the city of Jharkhand, Sheetal said many of which came from construction work and non-paved roads to add air dust .
“Vehicle pollution and industry also add PM2.5 and PM10 pollutants but coal mines and stone crushers are the main causes,” he said.
