DPCC plans expansion of state labs to facilitate real-time water testing

The Delhi Pollution Control Committee (DPCC) has proposed granting 'state' laboratory status to all labs in government colleges and those under the Delhi Jal Board to facilitate real-time water testing across the national capital, officials said on Monday. The proposal was made during the 74th board meeting of the DPCC on February 13, 2025, at the Delhi Secretariat, where critical issues such as recruitment, pollution control measures, and infrastructure improvements were discussed, they said. Currently, Delhi has only one state laboratory for water testing. The proposed move aims to bolster large-scale water quality monitoring and enhance data accuracy, they added. The DPCC is also set to issue a public notice to gauge the willingness of government institutions to participate in the initiative. "In the last meeting held in September 2024, it was directed that more labs, including Delhi Jal Board facilities and those in government colleges, be recognized as state labs to support ..

Indian refiners test FOWE's emulsion tech to clean polluting bunker fuel

Indian oil refineries have initiated tests of fuel emulsion systems from a Monaco-based company to clean highly polluting bunker fuel as they eye significant benefits, including substantial fuel cost savings and a reduction in environmental impact of the high carbon-emitting fuel used in ships. Two state-owned oil firms deployed Fowe Eco Solutions' (FOWE) patented Cavitech devices at their refinery and depot installations to check the result of emulsified fuel oil (bunker fuel), sources aware of the matter said. Trials showed substantial reduction in emissions and better fuel efficiency, they said, adding the refiners are now looking at tests for its commercial use. Requiring very little initial investment and eliminating the need for installation downtime, the FOWE uses a process known as cavitation using its Cavitech device, which allows emulsification of fuel oil, also known as furnace oil, with fresh water. This process, which does not require any additives or further processing

Thane civic body cracks down on developers flouting pollution control rules

The civic authorities in Maharashtra's Thane city have pulled up developers for flouting pollution control guidelines during construction activities and halted work at the sites of seven developers, an official said on Saturday.

Delhi's Bawana plant sparks protests, locals threaten to boycott polls

The proposed waste-to-energy plant in Bawana has taken centre stage ahead of the Delhi Assembly elections with the local residents raising environmental and health concerns and a section threatening to boycott the polls if the project proceeds. The plant has been planned on a 15-acre site near the Treatment, Storage, and Disposal Facility (TSDF) for hazardous waste in DSIDC Sector 5. Speaking to PTI, residents from over 15 nearby villages have claimed that the project will result in the destruction of trees, increased air and water pollution, and long-term health risks, including respiratory ailments as well as neurological disorders. They also argued that emissions from the waste-to-energy (WTE) plant, such as dioxins, furans, particulate matter (PM2.5 and PM10), and even heavy metals like mercury and lead, will not just worsen the air quality but also endanger public health. The toxic emissions from this plant will put our lives at risk. We're already struggling with pollution fr

Russia warns of environmental harm as oil from tankers pollute beaches

Russian officials warned of severe environmental damage Wednesday as thousands of people came out to clean up tonnes of fuel oil that spilled out of two storm-stricken tankers more than two weeks ago in the Kerch Strait, near Moscow-occupied Crimea. More than 10,000 people, largely volunteers, raced to rescue wildlife and remove tons of sand saturated with mazut, a heavy, low-quality oil product, according to Russian news reports. Authorities in Russia's southern Krasnodar region last week announced a region-wide emergency, as the fuel oil continued washing up on the coastline 10 days after one tanker ran aground and the other was left damaged and adrift on December 15. The move came days after Russian President Vladimir Putin called the oil spill an ecological disaster. On Wednesday, New Year's Day, Krasnodar officials said the oil kept on surfacing on the beaches of Anapa, a popular local resort. More than 71,000 tons of contaminated sand and soil had been removed along 56 ...

Residential sector key source of PM2.5 pollution in north India: Study

Pollution in east, north and central Indian cities primarily comes from residential and transportation sectors, while in western India, industry and energy are the main contributors to local PM2.5 pollution, a study has found. Published in the journal Modeling Earth Systems and Environment, the study also found that PM2.5 pollution in cities in south India majorly comes from the industry and residential sectors. Researchers from the Indian Institute of Tropical Meteorology, Maharashtra, and the Indian Institute of Technology Roorkee, analysed pollution levels in 53 cities, having more than a million population during the winter of 2015-2016. Residential emissions -- from burning biomass for cooking and heating -- were found to be the leading contributor to local PM2.5 pollution in Srinagar (68 per cent), Varanasi (37 per cent), Allahabad (34 per cent) and Kanpur (33 per cent). The transportation sector's contribution to local PM2.5 pollution was found to be higher in north Indian .

Man-made products could be storing 8.4 bn tonnes of carbon: Study

About 8.4 billion tonnes of carbon is estimated to have been accumulated and stored in long-lasting products from around the world made by humans, such as plastics and buildings, between 1995 and 2019, according to a study. Researchers at the University of Groningen in the Netherlands said this 'fossil carbon' added to the 'technosphere' -- the sum of all human-made objects, both in use and discarded -- equals around 93 per cent of carbon dioxide emissions from around the world in 2019. They added that the carbon locked up in the 'technosphere' has a huge potential to add to greenhouse gas emissions. Increasing the lifetime of products and recycling rates are two ways to reduce the amount of fossil carbon entering waste streams, the researchers suggested. "Over these 25 years (1995-2019), 8.4 billion tons of fossil carbon have accumulated, with approximately 0.4 billion tons added each year, with a huge potential for further contribution to anthropogenic greenhouse gas emissions,"

No data to establish correlation of disease due to air pollution: Govt

Air pollution is one of the aggravating factors for respiratory diseases, however, there is no conclusive data available in the country to establish a direct correlation between any disease caused exclusively by air pollution, MoS for Health Prataprao Jadhav told the Lok Sabha on Friday. The health effects of air pollution are synergistic manifestations of factors which include food habits, occupational habits, socioeconomic status, medical history, immunity and heredity etc. of the individuals, Jadhav said in a written reply.
