Every additional μg/m3 of lead in air increased assault rates 21 years later (163 per 100K) — accounting for 29.8 % of the variance in assault rates 21 years later (compared to 5% for proportion of youth or finishing high school)

For every additional μg/m3 of lead in air, assault rates 21 years later increased by 163 per 100,000 population (see Table 3). Lead in air was the strongest predictor in the model, accounting for 29.8 % of the variance in assault rates 21 years later. By comparison, the proportion of the population aged 15–24 accounted for 5.4 % of the variance, and the proportion of …

Link between air pollution and anti-social behavior – raises crime rates 6-8% in spring and summer in Chicago study

The University of Chicago’s Crime Lab has been evaluating risk factors associated with crime include gender, age, race, economic status, exposure to violence, and community instability — now extending to a  recent study on how environmental factors may also affect crime. The study found a significant relationship between air pollution and criminal behavior. The researchers were able to attribute $1.8 million annually in extra crime-related …

Low Emission Zones & bans of high emitting vehicles, to reduce air pollutants

Local Emissions Zones (LEZ) can be an effective way of reducing PM10 and soot emissions. An increasing number of cities are implementing LEZs, either for all vehicles or for heavy goods vehicles (HGVs) only. The LEZs which are for heavy goods vehicles only were graded lower than the LEZs for all vehicles. Also these zones should be introduced early, should …

What do wind development trends mean for health, jobs, cities and transportation?

The Wind Vision Report  takes America’s current installed wind power capacity across all facets of wind energy (land-based, offshore, and distributed) as its baseline—a capacity that has tripled since the 2008 release of the Energy Department’s 20% Wind Energy by 2030report—and assesses the potential economic, environmental, and social benefits of a scenario where U.S. wind power supplies 10% of the …

“In the future, it will be necessary to transport goods in urban environments…with the lowest possible emissions and noise,” Mercedes said in a press release. “By now large cities such as London or Paris are considering a ban on internal combustion engines in city centers in the future. That means: there will be fully electric trucks”

Mercedes-Benz has unveiled the world’s first big rig that drives without a drop of fuel. The Mercedes-Benz Urban eTruckMercedes Benz The new Mercedes-Benz Urban eTruck has an electrically driven rear axle and is powered by three lithium-ion battery modules. The zero-emission vehicle has an admissible total weight of up to 26 tonnes with a range of 200 kilometers (124 miles). …

Vancouver proceeds toward 100% renewable energy – including transport and heating – by 2050. Here’s how they are doing it!
