Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. —Platt et al.

Swiss study finds that studies on air pollution that ignore impact of noise overestimate effects of pollution on heart attacks

Green Car Congress

Air pollution and transportation noise are both associated with an increased risk of heart attacks. However, studies on air pollution which do not take into account traffic noise tend to overestimate the long-term effect of air pollution on heart attacks, according to a study conducted by the Swiss Tropical and Public Health Institute.

Air pollutant emission 2010 limits exceeded in twelve EU Member States; road transport NOx a main factor

Green Car Congress

The directive covers four main air pollutants: sulphur dioxide (SO 2 ), nitrogen oxides (NO x ), non-methane volatile organic compounds (NMVOCs) and ammonia (NH 3 ). These pollutants can cause respiratory problems, contribute to the acidification of soil and surface water, and damage vegetation. —EEA Executive Director Prof.

Study finds significant proportion of childhood asthma cases may be attributable to air pollution

Green Car Congress

Findings of a study led by the Barcelona Institute for Global Health (ISGlobal) and published in the European Respiratory Journal suggest that a significant proportion of childhood asthma cases may be attributable to outdoor air pollution, and that these cases could be prevented. Meeting the minimum air pollution levels for NO 2 (1.5?µg·m

New maps give Europeans close-up picture of air pollution from diffuse sources

Green Car Congress

New online maps published by the European Commission and the European Environment Agency, in close cooperation with the Institute for Environment and Sustainability (IES) of the Joint Research Centre, allow citizens to pinpoint the main diffuse sources of air pollution, such as transport and aviation. NO x emissions from road transport.

Historical trends of (A) ΣPCDD/F, (B) ΣPCB, and (C) ΣDDT in sediment from Lake Oberaar and from low-altitude lakes in Switzerland, normalized relative to their maximum historical peaks. The “second peak” for Lake Oberaar supports the hypothesis of pollutant release from melting. Credit: ACS, Bogdal et al.
