Study links increased black carbon pollution to increase in cases of lung adenocarcinoma worldwide

Green Car Congress

An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. The results of the study were published in the journal Atmospheric Environment. g/m 3 ) increment of black carbon is associated with a 12% increase in LADC incidence globally.

WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO. nitrogen dioxide (NO?)

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon. —Mark Jacobson.

Study: plant roadside hedges rather than trees to combat near-road pollution

Green Car Congress

Urban planners should plant hedges—or a combination of trees with hedges—rather than just relying on roadside trees if they are most effectively to reduce pollution exposure from cars in near-road environments, according to a new study from the University of Surrey.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al. 2c07030

European Environment Agency report finds carbon capture and storage could also impact air pollution

Green Car Congress

Carbon capture and storage (CCS) involves capturing carbon dioxide released by power stations and other industrial sources, and burying it deep underground. The report shows that while CCS may have an overall positive effect on air pollution, emissions of some pollutants may increase.

New iron catalyst helps preferentially reduce NO to hydroxylamine; pollution control and clean energy

Green Car Congress

Researchers from Korea and France have shown that iron–nitrogen-doped carbon is an efficient and durable electrocatalyst for selective nitric oxide reduction into hydroxylamine. Among the major pollutants, nitrogen oxide (NO x ) accumulation can cause severe respiratory diseases and imbalance in the Earth’s nitrogen cycle.
