2018/09/19: Nine out of ten people live in places where outdoor air pollution exceeds guidelines set by the World Health Organization (WHO). Hotspots are congested urban areas in low- and middle-income countries such as India, Nigeria and China. In some megacities — Mexico City, for example — authorities have begun to adopt cleaner vehicle standards. But fine particulate matter and nitrogen dioxide from vehicular traffic, energy production, industry and heating remain a serious public-health risk in most built-up areas.
Even many cities in wealthy Europe fail to meet the WHO standards.
as air-quality concerns continue to grow, the forum must liaise more with city leaders and health specialists to make sure they get the tools and data they need.
The results of this environmental science should be shared with countries worldwide. The situation is bad in rich countries: the WHO says that about half of city dwellers in developed nations are exposed to air that does not meet its guidelines. In cities of more than 100,000 people in the developing world, that figure rises to include almost everybody (97%). India alone has nine of the world’s ten most-polluted cities. Air is a shared resource. Research and tools to make it safe to breathe should be shared as well.
Starting off with updates on the two and three-wheeler inventory and baseline study being carried out, Clean Air Asia Transport Specialist Joemier Pontawe said data from the Land Transportation Office (LTO) showed that of the 5 million vehicles registered in 2002, two and three-wheelers accounted for 43 percent, rising to 60 percent of the total 10 million motor vehicles registered in 2017.
“This reveals a surge in two and three-wheelers within a decade, and it is important to note we only have information on gasoline-powered two and three-wheelers and none yet on electric units that have entered the market,”
2018/09/16: there is a massive association between air pollution a mother breathes in and the effect it has on the foetus.
This study suggests [these] children have worse life chances when it comes to their education and their future jobs.
children with early onset and persistent asthma fared far less well in education than those without the condition.
children with asthma were three and half times more likely to leave school at the age of 16 with only basic education and were also twice as likely to drop out of university courses.
Our results provide the first evidence that inhaled pollution particles can move from the lungs into the circulation and then to the placenta.
We do not know whether the particles we found could also move across into the foetus, but our evidence suggests that this is indeed possible.
The evidence suggests that an increased risk of low birthweight can happen even at levels of pollution that are lower than the European Union recommended annual limit.
This new research suggests a possible mechanism of how babies are affected by pollution while being theoretically protected in the womb.
We need stricter policies for cleaner air to reduce the impact of pollution on health worldwide because we are already seeing a new population of young adults with health issues.
The difference between emission levels across the sites was more correlated with the number of large trucks on the road rather than number of cars.
Researchers found that air pollution levels right beside a major trucking route within a city were close to levels seen beside Highway 401, despite the road carrying less than one-tenth of the vehicle traffic. “This was in part due to differences in wind and proximity to the road but, surprisingly, the number of vehicles didn’t make that much of a difference,” said Evans.
The data also revealed a significant drop in emissions on the 401 on the weekends, when personal vehicle traffic is still very high, but the volume of large truck traffic is low.
2018/09/04: While others were addressing the public health issues of the thick air pollution, Peters’ co-worker Andre Nobre from Cleantech Energy Corp., whose field is also solar energy, wondered about what impact such hazes might have on the output of solar panels in the area. The findings show that these effects are indeed substantial. In some cases it can mean the difference between a successful solar power installation and one that ends up failing to meet expected production levels - and possibly operates at a loss.
air quality in India is bad and is becoming a serious public health issue with serious repercussions on the quality of life and the economy.
The database shows that air pollution is a global problem nine out of ten people breathe highly polluted air and about 80% of the people living in cities have to breathe in poor air that exceeds health standards.
Unlike China, governing air pollution has proved to be much more difficult in India with multiple layers of government and differences between the state and the central government. In India, there is a gap in air pollution policy that restricts its implementation. Moreover, outrage over deteriorating air quality has been restricted.
Chinese miners dug up 3.87 billion tonnes of coal last year, leaving the country grappling with major environmental problems from crippling air pollution to dried-up riverbeds
China's recent move to limit imports of the dirtiest coal from 2015 onwards is a scary prospect for Australian miners. The proposed restrictions will ban the burning of coal with high levels of ash or
The National Climate Assessment, recently released by the Obama administration, makes clear that climate change is deadly, and Americans are already dying from it.
Get a load of this: It's not poor people whose nostrils get the dirtiest air. It's people of color -- even wealthy ones.
