OSU researchers find small particles from tires inhibit growth of organisms in freshwater, coastal estuaries

Green Car Congress

These findings led the researchers to conclude that even at current environmental levels of tire-related pollution, which are expected to increase, aquatic ecosystems may be experiencing negative impacts. Exposure to nano tire particles enhanced toxicity in comparison to leachate alone. Credit: John Dickens. Resources. Siddiqui, J.M.

Study found highly elevated PM2.5 in pre-COVID-19 subway air in NE US; NYC the worst

Green Car Congress

Our findings add to evidence that subways expose millions of commuters and transit employees to air pollutants at levels known to pose serious health risks over time. By comparison, aboveground air concentrations for all measured cities averaged just 16 ?g/m g/m 3 ), followed by the MTA New York at 251 ?g/m

Setback distances should be revisited to address temporal variability and pollution controls in vent emissions. By comparison, the California Air Pollution Control Officers Association (CAPCOA) used an estimate of 0.11 The research is supported by a grant from the National Institutes of Health (ES009089). pounds and 1.7

German OEMs to upgrade emissions control on 5.3M Euro 5 and 6 diesels, contribute to €500M Sustainable Mobility fund

Green Car Congress

With respect to the emissions updates, the OEMs must also provide proof that the changes do not negatively impact any other parameters relevant for type approval—such as pollutant and CO 2 emissions, fuel consumption, noise and engine power. Excessively high pollution affects air quality in many German cities.

European Court of Auditors finds 2/3 of EU-funded transportation projects underutilized

Green Car Congress

This also implies underperformance in terms of economic and social benefits, such as reduction of pollution levels and congestion. Meanwhile, European cities need to enhance mobility and to reduce congestion, accidents and pollution through local mobility policies.
