It provides high-level trends on the status of renewables in the wider fossil fuel-dominated energy system in the context of global challenges such as climate change, development goals and the geopolitical landscape. Urgent …
Jaipur: A day after the massive fire broke out in Indian Oil Corporation depot on the outskirts of Jaipur, thick smoke clouds enveloped the nearby areas on Friday posing serious health hazards to people living in the vicinity. While official figures were not available, sources at SMS Hospital said at …
The Delhi Pollution Control Committee (DPCC) has asked for registration of all diesel generators in the city to curb noise pollution. The decision comes seven years after the Ministry of Environment and Forests issued a notification in 2002, seeking diesel gensets to stick to pollution limits. Once implemented, it will …
Pollution from carbon monoxide, nitrogen dioxide, sulphate and suspended particulate matter due to ignition of fireworks during the festival of Diwali is well established. Although surface ozone exhibits high natural variability throughout the year, any short term enhancement in ozone levels coupled with high level of pollutants during Diwali might …
With the increase of motor vehicles, ambient air pollution related to traffic exhaust has become an important environmental issue in China. Because of their fast growth and development, children are more susceptible to ambient air pollution exposure. Many chemicals from traffic exhaust, such as carbon monoxide, nitrogen dioxide, and lead, …
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 …
European environment ministers could agree to tighten up widely flouted acid pollution laws this week after rapid progress in recent negotiations over industrial emissions brought a compromise within reach. "There has been significant progress in recent weeks, and member states are taking a cooperative approach," Jos Delbeke, number two at …
As an engineering student in the 1960s, Takeo Fukui picked the analysis of nitrogen dioxide emissions as his senior thesis with one goal in mind: joining Honda Motor to get a foothold in the world of motor racing. He made the cut but, as luck would have it, Honda pulled …
Traffic pollution is known to cause chronic bronchitis and asthma, killing thousands every year. But that is not all. Simply living beside a busy road has its consequences. Particles in vehicular exhaust can stick to lungs for longer than was known, endanger the health of an unborn child, lead to …
The U.S. government will reverse a Bush administration policy and increase the role of scientists in setting air standards for criteria pollutants harmful to human health, Lisa Jackson, the administrator of the Environmental Protection Agency, said on Thursday. Jackson said the EPA will reinstate the role of a policy document …
President Barack Obama on Tuesday unveiled an aggressive policy initiative to increase U.S. auto fuel efficiency and regulate auto emissions. In a bid to reduce climate-warming greenhouse gasses, countries around the world have adopted a patchwork of ways to regulate emissions from vehicles. These varied approaches carry with them different …
Chronic exposure to traffic-related air pollution (TRAP) may contribute to premature mortality, but few studies to date have addressed this topic. This study assessed the association between TRAP and mortality in Toronto, Ontario, Canada.
Asia's increasing population and economic growth has meant that the energy demand is doubling every 10 years, which is more than twice the world average, resulting in an increased risk of human exposure to higher air pollution from fossil fuel burning. In countries, where more than third of the population …
Poverty is a major determinant of population health, but little is known about its role in modifying air pollution effects. The researchers set out to examine whether people residing in socially deprived communities are at higher mortality risk from ambient air pollution.
Various factors can modify the health effects of outdoor air pollution. Prior findings about modifiers are inconsistent, and most of these studies were conducted in developed countries. The researchers conducted a time-series analysis to examine the modifying effect of season, sex, age, and education on the association between outdoor air …
To assess the relationship between individual-based exposure to traffic-related air pollutants and allergic disease outcomes in a prospective birth cohort study during the first 6 years of life.
Hydroxyl radicals are often called the "detergent" of the atmosphere because they control the atmosphere's capacity to cleanse itself of pollutants. In this article the researchers show that the reaction of electronically excited nitrogen dioxide with water can be an important source of tropospheric hydroxyl radicals.
Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing and terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more bioavailable nitrogen to enter groundwater and surface waters. Large-scale nitrogen budgets show that an average of about 20
Denitrifying bacteria and hungry plants do sterling work in disposing of the nitrates that we pump into rivers and streams. But as the excess influx goes up and up, the efficiency of removal goes down and down.
