A new study led by University of Chicago researchers finds an association between exposure to environmental pollution and an increase in the prevalence of neuropsychiatric disorders. Our studies in the United States and Denmark show that living in polluted areas, especially early in life, is predictive of mental disorders.
Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests an analysis by researchers at the US National Institutes of Health (NIH). Short-term exposure to most types of air pollutants may increase the risk for NICU admission.
They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. L/2002 calibration and 6.4 Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L/2004 calibration engines.
A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. Even though the CO 2 enhancements over background were comparable in the two years, about 25 ppm in 2002 and 35 ppm in 2010, the ?CO/?CO2 CO2 ratio for this flight track segment decreased from 24.5
A team from the US National Renewable Energy Laboratory and the Colorado School of Mines has measured gas phase and particle-associated non-regulated pollutant emissions from a heavy-duty engine operating both with and without a catalyzed DPF and operating on biodiesel fuel. Experiments were conducted on a 2002 model year 5.9
Highway vehicles are responsible for a declining share of pollutants in the US, according to data gathered by the US Department of Energy (DOE). More than half of all carbon monoxide (CO) emissions in 2002 were from highway vehicles; by 2016 that fell to 30%.
Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Repeated scans were done for nearly all participants between 2002 and 2005; for a subset of participants between 2005 and 2007; and for half of all participants between 2010 and 2012.
These new SIPs demonstrate that, by 2024, pollution will be reduced to the level needed to attain the 1997 8-hour ozone standard of 0.08 ppm by 2024, NO x will have to be reduced by 75% and VOCs by 25% from 2002 levels. ppm by 2024, NO x will have to be reduced by 90% and VOCs by 52% from 2002 levels. For the SJV to attain 0.08

The complaint filed in Manhattan federal court alleges that from approximately 2005 until at least late 2015, Toyota systematically violated Clean Air Act automobile defect reporting requirements designed to protect public health and the environment from harmful air pollutants. Representations to EPA.
The standards were formerly known as “LEV III” (for the third stage of the Low Emission Vehicle standards) and “Pavley II” (for the second, post-2016 stage of California’s pioneering greenhouse gas standard, established under AB 1493, the 2002 law authored by California state senator Fran Pavley). Earlier post.).
Maritime traffic on the world’s oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic. The number of ships traversing the oceans grew by 60% between 1992 and 2002.
The program is geared to help small California-based fleets replace their older, polluting trucks with newer, cleaner models. Previously, the maximum amount of a voucher was $35,000; Trucks with 2002 and older engines may qualify for a newer truck.
Comparable data on noise exposure in Europe is a prerequisite to set up EU policies to reduce noise pollution, a growing health and economic concern all over Europe. Member States will have to start using the new methods for the next round of EU-wide strategic noise mapping in 2017.
While properly engineered conversion systems can reduce or at least not increase emissions, poorly designed systems can lead to much more pollution.

The 7 Series has get a combined sub-20mpg and has an air pollution index of 6 out of 10. For comparison purposes, the 2002 Toyota RAV4 EV plug-in electric car has a mpg(equivalent) of over 100; and a best possible air pollution index of 10.)
The result, he says, is that the Indian Ocean has had less time than the Atlantic and Pacific to dissipate lead pollution. They found that lead levels began to increase in the mid-1970s, peaking in 2002 and 2003 before beginning to decline—a timeline consistent with the region’s pattern of industrialization and leaded gasoline use. “It
Apart from contaminated sites, the mercury pollution detected today is often found in locations very far away from its original source. UNEP produced its first Global Mercury Assessment in 2002 and a subsequent study in 2007. Use of coal for power generation and industry is increasing, especially in Asia.

A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks.
One altfuel epiphany Pogue blogged in May, 2006 came watching The Amazing Race 9 (CBS) in Brazil, where sugar cane-based ethanol has eliminated petroleum imports and reduced pollution. I invite Mr. Pogue to take a ride "back to the future" in my 2002 Toyota RAV4 EV. Why can't we do something like that, he wondered.
After the UK had begun taxing vehicles according to CO 2 emissions, the share of registered new diesel cars increased from 26% in 2002 to 38% in 2005. The study also focused on climate impacts alone, without comparing with the adverse health impact caused by the air pollution.
The relationships between IVOCs and other pollutants were examined to develop methods for estimating IVOC emissions from existing data. IVOC emissions were also measured from five SOREs used in lawn and garden equipment, including two 2-stroke and three 4-stroke engines manufactured between 2002 and 2006. —Zhao et al.
A new systematic review by The Lancet found that “people living in e-waste exposed regions had significantly elevated levels of heavy metals and persistent organic pollutants,” and it advocated for “novel cost-effective methods for safe recycling operations … to ensure the health and safety of vulnerable populations.”
They collected data using a multi-part online survey, and elicited driving patterns and recharge potential using a plug-in potential diary of driving and parking for a vehicle purchased new (model year 2002 or later) that is driven several times per week by the respondent’s household. the electric range capability—of the PHEV.
In 2002 when she was just a freshman California Assemblywoman, this former school teacher worked with Bluewater Network (which later merged with Friends of the Earth ) to author the Assembly Bill that made California the first state to reduce greenhouse gas emissions in automobiles. See, you really should have been there.

No one wants air pollution in our cities. They will drag their feet for next few years trying to shove their garbage pollution scooters and motorcycles down our throats, while selling compliance EV's in a limited fashion. On Feb 28th 2002, i got a message saying the scooter has left the factory.
But theyve needed definitive proof that PHEVs wont increase pollution. CA, NY, MA and other states have had Zero-Emission Vehicle programs since the early 1990s because battery electric vehicles in those states, taking into account power plants, are far cleaner than gasoline cars in reducing urban air pollution and smog.
Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.
Dont PHEVs just shift pollution from gasoline cars to power plants? But its monumentally less pollution , even on the national (half-coal) grid. And its easier to clean central power plants than millions of vehicles. And utilities are increasingly being mandated to increase their percentage of power from renewable sources.
