Recently, the BBMP Additional Commissioner for public health, D Randeep, launched a network of 40 air quality monitoring devices that have been installed across the city. This has been seen as a positive move in controlling the city’s increasing air pollution when it comes to accountability with facts. With construction …
JAIPUR: Industrial hub in Alwar district, Bhiwadi was at the fifth place in the list of cities across world with the worst air pollution in 2018, according to a new study by Swiss-based company AirVisual and Greenpeace. Another city of the state, Jodhpur is at the 12 place in the …
A team of researchers including University of New Mexico economics professor Andrew Goodkind is addressing the deadly problem of particulate matter air pollution in the U.S. and how to best mitigate it. Their article, titled "Fine-scale damage estimates of particulate matter air pollution reveal opportunities for location-specific mitigation of emissions," …
Two-year-old Thayi loves the aerosol therapy room at Senegal's Albert Royer Children's Hospital, where she gets to fall asleep on her mother's lap, breathing deeply - something that is usually hard to do. The mask over her face pumps out medicine that soothes her asthmatic lungs, a condition worsened by …
KOLKATA: There has been an alarming rise in asthma and chronic bronchial complications in newborns in Kolkata with no history of these issues in their parents. These can only be attributed to the city’s sharply declining air quality. Worse, mothers inhaling toxic air are impacting the children in their wombs, …
A majority of 39 northern Chinese cities have failed to meet anti-pollution targets over the six-months to end-March, a Reuters study of official data showed, adding to fears the war on smog has lost momentum. Chinese Premier Li Keqiang declared a “war on pollution” in 2014 and the government has …
This paper studies the impact of six main air pollutants on three key dimensions of subjective well-being (SWB) – life satisfaction, hedonic happiness and mental health. Match a nationally representative survey in China with local air quality and rich weather conditions according to the exact date and county of each …
Particulate matter such as PM 2.5, which are less then 2.5 microns in size, are considered especially dangerous as these can penetrate deep into the lungs and enter the bloodstream. In the last five years, the level of particulate matter (PM) 2.5, a pollutant, has crossed the permissible limit in …
PANJIM: Indian Institute of Technology (IIT) Bombay, which is undertaking the Source Apportionment Study of Vasco, with regard to the pollution caused due to handling of coal at Mormugao Port Trust (MPT), has observed that the pollution level of Vasco is “similar” or “many times better” than other towns of …
Deteriorating air quality being a major concern in India, Magneto CleanTech has come up with a product that traps bacteria and germs. The product can be fixed with any type of air-conditioner and costs around ₹40-45 per sq ft. “Now that food is sanitised and water purified, it’s time to …
This study, in collaboration with the International Institute for Applied Systems Analysis (IIASA), examines India’s National Ambient Air Quality Standards (NAAQS), existing policies and emission control measures aimed at curbing air pollution, factors contributing to air pollution across the country, and future pathways towards meeting NAAQS over the coming decades. …
In the state of Punjab in India, burning residue from the annual rice paddy harvest is a practice that dates back decades. Crop waste burning emits particulate matter (both PM10 and PM2.5) and greenhouse gases (GHG), which aggravate the poor air quality in Punjab, Delhi and the National Capital Region …
Fixing Delhi's air quality requires a deep understanding of the sources that contribute to air pollution. Despite multiple source apportionment studies specific to Delhi NCR, policymakers can’t design an effective action plan due to varying estimates. This study brings clarity on the existent discrepancies and attempts to understand the gaps …
NEW DELHI: As Delhi and its neighbours struggled to rein in the monster of pollution for yet another winter, data showed that construction and demolition activity was the biggest source of foul air in the National Capital Region from December 2018 to February 2019. The data was collated from the …
As air quality improves, the invisible chemistry happening in the air around us is changing. Skies should clear up as emissions drop, but recent results suggested that declining nitrogen oxides can create an environment where airborne carbon-containing compounds more easily convert into small particles that harm human health. Regulators can …
Coal is everywhere in Mongolia’s frigid capital. It sits beneath the towering smokestacks of power plants in piles as big as football fields. Drivers haul it through town in the open beds of pickup trucks. Vendors stack yellow bags of the stuff along roadsides, and jagged pieces spill from metal …
Aerosol pH is difficult to measure directly but can be calculated if the chemical composition is known with sufficient accuracy and precision to calculate the aerosol water content and the H+ concentration through ion balance. In practical terms, simultaneous measurements of at least one semi-volatile constitute, e.g. NH3 or HNO3, …
Air pollution could be causing double the number of excess deaths a year in Europe than has been estimated previously, according to a study published in the European Heart Journal [1] today (Tuesday). Using a new method of modelling the effects of various sources of outdoor air pollution on death …
Air pollution is killing more people every year than smoking, according to research published on Tuesday that called for urgent action to stop burning fossil fuels. Researchers in Germany and Cyprus estimated that air pollution caused 8.8 million extra deaths in 2015 - almost double the previously estimated 4.5 million. …
U.S. air pollution is disproportionately caused by white consumers, while African-Americans and Hispanics are burdened most by the emissions, a peer-reviewed study showed on Monday. On average, African-Americans are exposed to about 56 percent more fine particulate matter pollution than is caused by their consumption of goods and services, said …
