Coming at last, new study to identify sources of pollution, Pg4

Key Highlights:

• The Delhi government will collaborate with IIT Delhi and the Indian Institute of Tropical Meteorology Pune for a new air pollution source study.
• The study aims to pinpoint pollution sources, their extent, and localized characteristics, addressing concerns about outdated data.
• The Commission for Air Quality Management (CAQM) was directed by the Prime Minister’s Office on October 23 to expedite emissions inventory and source-apportionment studies for Delhi-NCR.
• Delhi Police has identified 62 high-traffic pollution hubs, a significant increase from the 13 previously identified pollution hotspots.
• The Delhi Pollution Control Committee (DPCC) will deploy 100 surveyors for a year-long audit of roads and dust-mitigation status.
• Penalties of Rs 7 crore have been imposed on 750 construction sites for violations, with 48 sites ordered to shut down.

Detailed Insights:

• The existing clean-air action plan, which guides anti-pollution measures, has not been updated since 2018, despite a source-apportionment study completed in 2023 that was not accepted by the government.
• The new study will help revise hotspot mapping and identify both city-wide and area-specific pollution patterns, providing a more accurate understanding of pollution sources.
• Deputy Commissioners and Municipal Corporation of Delhi (MCD) Deputy Commissioners have been instructed to conduct a seven-day survey of industrial areas to identify polluting and illegal units.
• Recent enforcement actions include 230 inspections across various departments, resulting in Rs 1 crore in penalties, even for government entities like the MCD, PWD, DDA, DSIIDC, and DMRC.
• Enforcement teams are actively addressing dust and burning violations, with 536 challans issued for dust mitigation failures and 633 for open burning.
• Thousands of heaters have been distributed across 1,407 RWAs to discourage the burning of bonfires by security guards, as part of a larger initiative to distribute 10,000 heaters citywide.

Key Concepts Involved:

• Source Apportionment: Identifying the contribution of different sources to overall pollution levels.
• Emissions Inventory: A comprehensive list of pollutants released into the atmosphere from various sources within a specific area.
• Air Quality Management: Strategies and actions taken to monitor, control, and improve air quality to protect public health and the environment.
