Cancer-causing benzene from oil refineries escaping into mostly minority and lower income neighborhoods exceeded the federal action level for 13 refineries across the U.S. in 2020, according to data from the U.S. Environmental Protection Agency. More than 530,000 people live within three miles of the 13 refineries in 2020, with …
Over the past two decades the issue of air pollution in the Kathmandu Valley has become of increasing concern as concentrations of ambient air pollution exceed international air quality guidelines and standards. The steady growth in road traffic has resulted in the increasing contribution of vehicle emissions to urban air …
Results of ambient air quality monitoring carried out during 2008 at various monitoring stations under National Air Quality Monitoring Programme by the CPCB. Pollutants found to exceed the standards in many cities are suspended particulate matter and respirable suspended particulate matter. Results of additional pollutants such as benzene and carbon …
Recent evidence has shown that humans metabolize benzene more efficiently at environmental air concentrations than at concentrations > 1 ppm. This led the researchers to speculate that an unidentified metabolic pathway was mainly responsible for benzene metabolism at ambient levels. They statistically tested whether human metabolism of benzene is better …
KOCHI: Is your expensive car or bike running on quality fuel? At a time when the oil PSUs are launching campaigns highlighting the quality of fuels distributed through their outlets, the arrest of four members of a gang involved in selling pilfered benzene to petrol pumps comes as a shocking …
The International Fuel Quality Center recently released a ranking of the top 100 countries based on the lowest benzene limits in gasoline. Colombia was at the top of the ranking with the lowest limit, followed by Canada and Luxembourg.
Draft new EU legislation that would limit harmful vapour emissions from petrol pumps was proposed on 4 December by the European Commission. Petrol vapour contains benzene, which is known to cause cancer, and contributes to the formation of ground-level ozone, one of the air pollutants that is most damaging to …
Cancer is the second leading cause of death among U.S. children with few known risk factors. There is increasing interest in the role of air pollutants, including benzene and 1,3-butadiene, in the etiology of childhood cancers. The goal of this study was to assess whether census tracts with the highest …
Petrochemicals are hydrocarbons, obtained from naturally occurring raw materials viz. petroleum, natural gas, coal etc. Coal was initially the basic raw material for organic chemical industry. However the basic feedstock has changed recently from coal to petroleum. This is attributed to the recent innovation and technological advance in the field …
vehicular pollution is common to most metros. A Kolkata-specific study has highlighted how vehicles in Kolkata emit cancer-causing volatile organic compounds (vocs). The study noted that specific vocs were found in very high concentrations in the city. "Levels of btex
Benzene is a human carcinogen. Exposure to benzene occurs in occupational and environmental settings. The researcher evaluated data from a cohort of 1,845 rubber hydrochloride workers. Benzene exposure
A Kannan has been feeling dizzy with fever for days, his limbs are shaky. He has come to the government hospital in Tamil Nadu's coastal Cuddalore town with others from nearby Kudikadu village with similar complaints. A common scene in a hospital. But the shock comes when one begins counting. …
Benzene exposure from vehicular sources and its health impact are relatively unexplored in India. We have investigated in this study hematology and lymphocyte subsets of 25 petrol pump attendants, 25 automobile service station workers and 35 controls matched for age, sex and socioeconomic conditions. The participants were non-smoking males of …
despite petrol's benzene content being lowered from 3 per cent to 1 per cent in 2000-2001, there has been no significant effect on the current ambient levels of this carcinogenic chemical. Benzene levels in air continue to be high according to two recent studies: Central Pollution Control Board's (cpcb's) Highlights …
the air around us is toxic, full of toxins that cause cancers, along with other serious ailments. The magnitude of air toxics is alarming, especially those emitted by vehicles. These are greater cause for concern because they are inadequately monitored. A recent study, Smoke Screen: Ambient Air Quality in India …
Mobile source air toxics come from four sources. One: some toxics are present in fuel and are emitted into the air when the fuel evaporates or passes through the engine unburned. Benzene, for example, is a component of gasoline. Cars emit small quantities of benzene in unburned fuel, or as …
the strongest acid: The world's strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. It is also one of the least corrosive. Called carborane acid, is the first
long time exposure to benzene has always been considered detrimental to human health, but now researchers from the Kurukshetra University, Haryana, have found that even an occasional exposure to benzene of an hour a day is sufficient to bring about adverse changes in genetic material of humans. Benzene is a …
What is the latest information on adverse health effects of diesel exhaust? Over 200 epidemiological studies conducted in different geographical locations of the world have shown a significant and consistent association between diesel emissions and increased deaths and cardio-respiratory illnesses such as heart attacks and strokes, allergies, asthma, bronchitis and …
living in an environment polluted with even low levels of benzene can cause cancer. While exposure to benzene at work places have been known to cause cancer, a study published recently in the American Journal of Epidemiology shows that exposure to low concentrations of the chemical such as those present …
