Rice, MD, MPH, a pulmonary and critical care physician at BIDMC. We suspected that these exposures would also be associated with pediatric asthma.
Studies have shown that air pollution can have negative effects on cardiovascular health and life expectancy. Information on the relationship between air pollution and kidney disease is very scarce. Air pollution levels were also assessed using space-borne sensors from NASA satellites. 2017030253.
Some of the current research into using autonomous vehicles to smooth traffic was inspired by a simple experiment done by Japanese researchers 10 years ago in which about 20 human drivers were instructed to drive in a ring at 20 mph. You have stop-and-go oscillation within less than a minute. —Marta Gonzalez.
In a paper published in the American Journal of Respiratory and Critical Care , researchers report that children exposed to higher levels of air pollution—even if relatively low—including fine particulate matter (PM 2.5 ) and soot (black carbon), had worse lung function than those living in less polluted areas. mL; -43.9,

Affordable and low polluting cabs are within our grasp and I urge manufacturers to accelerate efforts to produce them. Powered by a 100 kW (peak), 55 kW (continuous) motor, the cab is capable of achieving a top speed of 81 mph (130 km/h) and has a range of more than 250 miles (402 km) on a full tank of hydrogen.
Ford in Europe is introducing on the all-new Mondeo ( earlier post ) a new air filtration system that blocks up to 99% of pollen, almost all nitrogen dioxide—a key trigger of asthma—as well as gaseous pollutants and odors. Sneezing at a speed of 95 km/h (60 mph) can result in the driver “driving blind” for up to 20 meters.
The Mule M150 can carry a max load of 7 tons and is able to travel at a speed of up to 55 mph (89 km/h). While electric delivery trucks with a 7 ton capacity are new to inner city delivery applications, we believe they show significant potential in improving performance and environmental pollution. Earlier post.).
50 of BYD’s e6, five-seat crossover vehicles, each with a range of more than 160 miles (300 km) and a top speed of 88 mph (140 km/h), have been in service at Shenzhen-based Pengcheng Electric Taxi Company since 29 April 2010. kg) of carbon-dioxide pollution saved by this fleet in the first year. million kg) of carbon-dioxide.
We can eliminate environmental pollution from ships. The group drew up conceptual specifications: a 150-passenger commuter ferry that would travel four 50-mile round-trip routes each day at a top speed of 35 knots (~39 mph) about 60% of the time. Zero greenhouse gas and criteria pollutants during operation. —Tom Escher.
Most of the immediate project benefits will accrue in the San Joaquin Valley, an economically disadvantaged area with some of the highest pollution burdens in the country, as evidenced by CalEnviroScreen scores within the worst five percent in the state.
The bus utilizes alternative propulsion to address urban air pollution challenges and features a high-efficiency, zero-emission Dearman Engine ( earlier post ), powered by liquid nitrogen, alongside a conventional diesel engine. The hybrid system enables the bus to reduce noxious tail-pipe emissions, improving local air quality.
Maximum speed is 80 km/h (50 mph). During operation, the vehicle does not emit carbon dioxide, said to be a cause of global warming, or any other atmospheric pollutant such as nitrogen oxide; it is both highly energy-efficient and very quiet.
The City of London Corporation—the municipal governing body of the City of London—has banned the purchase of diesel vehicles for its business, in a drive to reduce public exposure to air pollution.
Air pollution from diesel engines may worsen allergy-induced lung impairment more when tiny particles are filtered from the exhaust than when they are not, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.

Even small amounts of PM 2.5
But the truth is it only addresses the local pollution issue; it neither addresses the congestion problems nor the parking issue most cities face today. Top speed is 45 km/h (28 mph). The current EV market is a fleet market, a B2B market, not a B2C market. A lot of people think the EV is the perfect car for the city. hp) and 17.0

mph) at full payload, with the added benefit of 100% starting torque. Electrification of all powertrain elements of the trucks and the mechanical elements for collecting refuse bins allow for significantly reduced noise pollution, zero local emissions and no idling during inactive periods. —Michel Bouton, CEO of PVI.
These are some of the hardest emissions to clean up due to the high cost of retrofitting the large number of trucks on the road today (around 1 million) with more advanced diesel engines or pollution controls, Quallion notes. Maximum voltage is 208V, with average voltage of 187.2V. Opportunities in the automotive market.
The truck easily maintained 55 mph up the 8% grade through the Altamont Pass. By utilizing battery-electric trucks, companies such as GSC can lower their operating costs while significantly improving air quality through the elimination of pollution caused by diesel trucks. It then picked up a return load back to the Port.
Up to a reference mass of 2380 kg, the complete vehicle has its emission characteristics tested on a chassis dynamometer, with the result being shown in pollutants per km. Above a reference mass of 2840 kg, the engine is tested on an engine dynamometer, with the result being indicated in pollutant emissions per kW of output.
If just 14 percent of journeys in central London were cycled, emissions there of the greatest vehicle pollutant, NO x , would fall by almost a third and over the years literally thousands of lives could be saved. It means more seats on the Tube, less competition for a parking place and fewer cars in front of yours at the lights.
The City of Madrid recently enforced tough temporary measures to tackle pollution, including limiting speed limits and banning passenger car access to the city center if NO x levels exceed acceptable levels. The new Class II specification Scania Citywide can be operated at speeds of up to 100 km/h (62 mph). meter 4x2 buses and 17 14.8-meter
