Walking in Delhi is a direct threat to lungs, this research report on pollution is really scary.

New Delhi: A joint study by the Physical Research Laboratory, Ahmedabad, and Delhi Technological University has examined the presence and effect of airborne nanoparticles (PM1 or smaller particles) on the respiratory system of pedestrians in Delhi. This study showed that the concentration of these particles on roadsides is 30% higher than in areas away from traffic. Residents of Delhi are exposed to around 10-18 million nanoparticles every day while walking on the road. Due to their microscopic size, these particles are more dangerous to health than PM2.5 or PM10.

Roadside air is 30% poisonous

This study was conducted in Rohini, North Delhi. In this, the effect of atmospheric nanoparticles on the human respiratory system was analyzed in all seasons. The study found that ultrafine particles contribute about 60-80% of the total particle number concentration in Delhi. The report said, ‘The number of respirable particulate matter concentrations in Delhi varies between 0.5 to 1 billion over the year…Particulate matter concentrations in Delhi range from 0.43-0.26 g/min over the year. The concentration of particles along urban roadsides is approximately 30% higher than in off-road environments. ‘These results are important for initiating mitigation measures to improve air quality and public health.’

Elsevier published this research report titled ‘Seasonal variation of particle number concentration in a busy urban street with exposure assessment and deposition in the human respiratory tract’. Published from. The research was conducted by a team of researchers including Rajiv Kumar Mishra, associate professor, Department of Environmental Engineering, Delhi Technological University, S Ramachandran, senior professor, Physical Research Laboratory, Ahmedabad, and Kanagaraj Rajagopal, research scholar, Advanced Air and Acoustics Research Laboratory, Delhi Technological University. .

The research report is scary

The study used a computerized model to find that more nanoparticles accumulate in the alveolar regions of human lungs. The report notes that ‘because these nanoparticles are approximately 500 times smaller than the size of a human hair, they penetrate deep into the lungs’ and ‘have the ability to enter our bloodstream’ and into various parts of the body, including the brain. May accumulate in parts. It was also found that concentrations of nanoparticles were higher near sources such as roadsides, where most of the population is exposed to these particles.

Rajeev Kumar Mishra, an author of the report, said, ‘Therefore, for a city like Delhi, people living in residential areas adjacent to roads will be more exposed to these particles. People working or living near roads, such as policemen, street vendors, drivers, motorcyclists, delivery personnel and the urban poor living near roads, are more sensitive to nanoparticles. The study also suggests that there is a need for policy formulation regarding concentrations of these particles to reduce nanoparticle emissions from engine sources to reduce the impact of these particles on the environment and human health.

bad condition of delhi

Overall, the microscopic nanoparticles present in Delhi’s air, which are 500 times smaller than a human hair, can reach our lungs and other body organs and cause serious health problems. People living along roadsides, such as traffic police, street vendors and delivery workers, are most at risk from these particles. Therefore, the government needs to make policies to reduce the emissions of these particles so that the air of Delhi can be made clean and safe. This study reminds us that clean air is our right, and we have to work together to achieve it.
