DPCC launches dust control portal for construction projects in Delhi

The Delhi Pollution Control Committee (DPCC) has launched a "Dust Pollution Control Self-Assessment" portal mandating all construction and demolition projects in the national capital to register on it and upload regular dust control audits. In line with the directives issued by the Commission for Air Quality Management (CAQM) on December 20, 2021, the DPCC now mandates that all construction and demolition (C&D) projects occupying a plot area of 500 square metre or more must register on a newly-developed web portal, the pollution control authority said in a notice. The portal is designed to facilitate online self-assessment and remote monitoring, ensuring that dust control measures are properly implemented across construction sites. It requires project proponents to conduct regular self-audits of dust control practices and submit fortnightly self-declarations, the notice said. Additionally, sites within the municipal areas of the National Capital Region (NCR) with plot sizes of 500

Greenpeace India warns of poor air quality in Bengaluru, Mangaluru, Mysuru

Three major cities in Karnataka -- Bengaluru, Mangaluru, and Mysuru -- have registered deteriorating air quality as the air pollution is on the rise, said a Greenpeace India report on Saturday. The report, 'Spare the Air 2' flags serious health concerns as the average PM 2.5 and PM10 levels soar in 10 major cities of southern India, significantly exceeding the air quality guidelines set by the World Health Organization (WHO). PM2.5, or fine particulate matter, is a type of air pollution that consists of tiny particles that are 2.5 micrometers or less in diameter. PM10 is an air quality term for particulate matter that is 10 micrometers. The report has analysed the air quality standards of Hyderabad, Chennai, Visakhapatnam, Kochi, Mangaluru, Amravati, Vijayawada, Visakhapatnam, Bengaluru, Mysuru and Puducherry. The lead researcher of the report Akanksha Singh said, "Clean air is fundamental to our health, yet this report reveals that particulate matter levels in all cities have ...

Delhi breathes clean air for 128 days in first half of 2024: Report

The national capital breathed clean air for 128 days of the first half of 2024, according to a Delhi government report. The report by the Delhi Pollution Control Committee (DPCC) said that the "Good days' (good/satisfactory/moderate days together) during the January-July, 2024, period was 128.

Wildfires growing under climate change, smoke threatens farmworkers: Study

As wildfires scorched swaths of land in the wine country of Sonoma County in 2020, sending ash flying and choking the air with smoke, Maria Salinas harvested grapes. Her saliva turned black from inhaling the toxins, until one day she had so much trouble breathing she was rushed to the emergency room. When she felt better, she went right back to work as the fires raged on. What forces us to work is necessity, Salinas said. We always expose ourselves to danger out of necessity, whether by fire or disaster, when the weather changes, when it's hot or cold. As climate change increases the frequency and intensity of wildfires around the world, a new study shows that farmworkers are paying a heavy price by being exposed to high levels of air pollution. And in Sonoma County, the focus of the work, researchers found that a program aimed at determining when it was safe to work during wildfires did not adequately protect farmworkers. They recommended a series of steps to safeguard the worker

CAQM issues advisory to curb open waste burning, cites poor GRAP compliance

The Centre's air quality panel has issued a new advisory to curb the open burning of municipal solid waste and biomass, including wood, dried leaves and other organic matter, in Delhi, stating that despite previous advisories, compliance with the Graded Response Action Plan (GRAP) Stage-II has been "far from satisfactory". In a bid to address the worsening air quality in Delhi during the winter months, the Commission for Air Quality Management in National Capital Region and Adjoining Areas issued an advisory and directed the additional chief secretary of the Directorate of Urban Local Bodies and the Municipal Corporation of Delhi (MCD) commissioner to ensure that resident welfare associations (RWAs) provide electric heaters to their security staff and other service workers. This measure is intended to prevent them from resorting to open burning of biomass for warmth, which is a common practice during the winter months. The commission highlighted that despite previous advisories, ...

Congress slams govt over rapidly deteriorating air quality across nation

The Congress on Thursday slammed the Centre over the issue of "deteriorating air quality", alleging that this government denies there is a real problem, underfunds programmes targeted at mitigating pollution and fails to utilise the resources that it allocates. Congress general secretary in-charge communications Jairam Ramesh said that among the lesser-known tragedies of "the non-biological PM's reign is the rapidly deteriorating air quality nationally" and the policy chaos that has characterised the government's response to it. In the last five years, the Central Pollution Control Board (CPCB) has left more than 75 percent of the Environment Protection Charge (EPC) and Environmental Compensation (EC) funds unspent, the former environment minister said on X. In total, Rs 665.75 crores have been left unutilised, he claimed. "Earlier this week in the Rajya Sabha, a Union Minister of State claimed that 'There are no conclusive data available in the country to establish direct correlat

Air pollution-related terminologies awareness low among urban poor: Study

Awareness about air pollution-related terminologies such as air quality index and particulate matter is "significantly" low among the urban poor in Delhi-NCR, according to a survey. The study conducted from December 2023 to January 2024 covered 500 people in Delhi and National Capital Region (NCR) cities of Noida, Ghaziabad, Faridabad and Gurugram. For the survey, they were divided into two groups -- residents of informal settlements and slums, and formal middle-class settlements. "Awareness of air pollution-related terminology was significantly lower among the urban poor. Only 10 per cent of people were aware of air pollution terms like AQI (air quality index) and PM 2.5, while 71 per cent of middle-class settlements were aware," the survey "Saaf Saans" conducted by NGO Chintan Environmental Research and Action Group said. PM 2.5 levels are fine particles that have a diameter less than 2.5 micrometers, more than 100 times thinner than a human hair and remain suspended in the air fo
