Interdisciplinary research at the University of Leicester has explored the impact of black carbon on bacteria in the respiratory tract

Governor Nyesom Wike has constituted a panel to investigate emergence of black carbon that recently took over the atmosphere across Port-Harcourt and its environs.

High vehicular emission levels have created pollution hotspots in city

People with low income often experience higher exposures to air pollutants.We compared the exposure to particulate matter (PM1, PM2.5 and PM10), Black Carbon (BC) and ultrafine particles (PNCs; 0.02–1 μm) for typical commutes by car, bus and underground from 4 London areas with different levels of income deprivation (G1 to G4, from most to least deprived). The highest BC and PM concentrations were found in G1 while the highest PNC in G3. Lowest concentrations for all pollutants were observed in G2.

Backward trajectories of individual Asian dust storm (ADS) events were calculated using the hybrid single particle Lagrangian integrated trajectory (HYSPLIT) at four representative stations in Korea. A total of 743 ADS events and associated 2229 (endings of altitudes at 1000 m, 1500 m, and 2000 m per ADS event) backward trajectories from four stations were traced from January 2003 to August 2015. Regardless of the locations of the observed stations and the threshold time divide, recent increase of ADS occurrence rate was statistically significant in 99.9 % confidence limit.

The impact of black carbon emissions on human health and climate are of global interest. Despite this, black carbon emission factors for marine engines and fuels are uncertain because of the challenges of measuring black carbon emissions.

Although many time-series studies have established associations of daily pollution variations with daily deaths, there are fewer at low concentrations, or focused on locally generated pollution, which is becoming more important as regulations reduce regional transport. Causal modeling approaches are also lacking. Researchers used causal modeling to estimate the impact of local air pollution on mortality at low concentrations.

Diesel engines power the dominant share of goods movement, construction equipment, and public transport vehicles in the global economy. This report presents a global strategy to reduce fine particulate (PM2.5) and black carbon emissions from the global fleet of on-road diesel vehicles. The strategy identifies 36 countries for immediate action.
