Study estimates the composition of non-exhaust atmospheric particulate matter from traffic

Green Car Congress

A study by a team of researchers in the UK has estimated the contributions of brake dust, tire dust, and resuspended dust to non-exhaust traffic particles as. However, these reductions in combustion emissions have not been accompanied by similar reductions in nonexhaust emissions—i.e. 90% by the end of this decade.

MAN Engines showcasing D3876 diesel engine for EU Stage V locomotives without exhaust after-treatment systems

Green Car Congress

One of its outstanding features is the in-line six, which meets the EU Stage V emission standard for locomotives without the need for an exhaust after-treatment system (EATS). This means that a single technical solution equally covers emission requirements for all currently recognised emissions threshold values up to EU Stage V.

These deteriorated structures are unsafe for their intended purposes; rapid deterioration reduces the expected lifespan of structures, thereby increasing the costs for maintenance or replacement. The features that lead to deterioration include cracks, disaggregation (breakdown into fine white powder) and delamination (separation into layers).

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.
