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. g/m 3 ) increment of black carbon is associated with a 12% increase in LADC incidence globally. Black carbon is a pollutant that is classified as under PM 2.5.

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

These are some of the findings of a new health assessment based on the Tropospheric Ozone Assessment Report (TOAR), an effort by the International Global Atmospheric Chemistry Project to create the world’s most comprehensive database of surface ozone observations from all available ozone monitoring stations around the globe.

Study finds pollution emitted near equator has biggest impact on global ozone

Green Car Congress

Since the 1980s, air pollution has increased worldwide, but it has increased at a much faster pace in regions close to the equator. They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane.

Study: ozone levels higher across China than in other countries tracking the air pollutant

Green Car Congress

Many countries regulate ozone because of the damage the pollutant does to plants and people. Since the 1990s, tighter controls on emissions of those ingredients have lessened ozone pollution in many European and US cities. The researchers think the harmful effects of surface ozone pollution are much less recognized.

Team finds high concentrations of combustion- and friction-derived magnetic air pollution nanoparticles in human hearts in Mexico City

Green Car Congress

Solid CFDNPs in air pollution are characterized by the abundant presence of strongly magnetic, iron-rich particles which condense and/or oxidize upon airborne release, often retaining a rounded or spherical shape as they cool. Erythrocytes were identified transferring ‘hitchhiking’ NPs to activated endothelium. Cross, Imad A.M.

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.
