Short-term exposure to air pollution in India kills 33,000 people annually: Study | India News – Times of India

BATHINDA: A new study published in the Lancet Planetary Health finds that even levels of air pollution below current Indian air quality standards lead to increased daily mortality rates in India. The study examines 10 Indian cities (Ahmedabad, Bengaluru, Chennai, Delhi, Hyderabad, Kolkata, Mumbai, Pune, Shimla, and Varanasi) and finds that 33,000 deaths annually are attributable to air pollution levels exceeding WHO guidelines.Notably, significant deaths occurred even in cities not typically associated with high air pollution. The authors analyzed PM2.5 exposure data and daily mortality counts from 2008 to 2019 to reach these conclusions.7.2% of all deaths (~33,000 each year) across all 10 of these cities could be linked to short-term PM2.5 exposure higher than the WHO guideline value o...

Carbon credits protecting forests use flawed calculations: Study – Times of India

PARIS: A new study published on Tuesday renewed concerns about the efficiency of carbon credits, which are bought by polluting industries like airlines to offset their greenhouse gas emissions.The study focused on a controversial type of carbon credit, which is based on protecting forests against any future deforestation.Under this scheme, a business buys one credit for protecting a forest in such a way that one tonne of carbon has been prevented from being emitted into the atmosphere.The peer-reviewed study, published in the journal Global Environmental Change, looked at how these credits are measured.It found that the baseline for the calculations -- one credit for one tonne of carbon dioxide saved -- lacked detail and accuracy, and the parameters were too flexible.As a result, this h...

Air pollution linked to 135 million premature deaths: Study – Times of India

SINGAPORE: Pollution from man-made emissions and other sources like wildfires have been linked to around 135 million premature deaths worldwide between 1980 and 2020, a Singapore university said Monday.Weather phenomena like El Nino and the Indian Ocean Dipole worsened the effects of these pollutants by intensifying their concentration in the air, Singapore's Nanyang Technological University (NTU) said, unveiling the results of a study led by its researchers.The tiny particles called particulate matter 2.5, or "PM 2.5", are harmful to human health when inhaled because they are small enough to enter the bloodstream. They come from vehicle and industrial emissions as well as natural sources like fires and dust storms.The fine particulate matter "was associated with approximately 135 milli...

Longer, intense heatwaves lead to rise in premature births: Study – Times of India

NEW DELHI: The increased frequency and intensity of heatwaves is resulting in preterm and early-term labor, a study has found. According to a new multi-institutional study published JAMA Network Open, premature births are increasing due to hot weather conditions to intense and prolonged heatwaves. The researchers analysed 5.3 crore births across the 50 largest metropolitan areas in the US over a 25-year period (1993-2017) in terms of daily counts of preterm and early-term births.The study—led by researchers from Emory University, University of Nevada Reno, Yale University, University of Utah and the National Center for Atmospheric Research—is the largest to date investigating the association between extreme heat and perinatal health.During a typical 40-week pregnancy, babies born before...

Single dose of Covid-19 vaccine sufficient for already infected people: Study | India News – Times of India

HYDERABAD: A single dose of Covid-19 vaccine is sufficient for an infected person as there was a greater antibody response when compared with those who have had no prior infection, according to a study released by AIG Hospitals on Monday.The city-based AIG Hospitals recently published a study conducted on 260 healthcare workers, who got vaccinated between January 16 and February 5, in the International Journal of Infectious Diseases (a peer-reviewed journal).The study was designed to assess the immunological memory response in all those patients.All patients were given the Covishield vaccine.The study also said Memory T-cell responses elicited by a single dose of vaccine were significantly higher in the previously infected group compared with those who had no prior infection.Commenting ...
