Fine particles trap more heat in atmosphere than previously thought
Fine particles in the air produced by road transport trap more radiation in the earth's atmosphere than previously estimated, and therefore may contribute more to global warming than realised, according to new research. In contrast, the impact of particles from shipping appears to reflect more radiation than previously thought, whilst the effect of particles from aviation is comparatively small. ...

ASTM D6562 - 06(2011) standard test method for determination of gaseous hexamethylene diisocyanate (HDI) in air with 9-(N-methylaminomethyl) anthracene method (MAMA) in the workplace
HDI is mostly used in the preparation of paints. For the last ten years, the use of isocyanates and their industrial needs have been in constant growth. Diisocyanates and polyisocyanates are irritants to skin, eyes, and mucous membranes. They are recognized to cause respiratory allergic sensitization, asthmatic bronchitis, and acute respiratory intoxication (4-7). The American Conference of ...

MARGA Instrument Enables on-Line Monitoring of Atmospheric Inorganic Gases and Aerosols
The Metrohm Monitor for AeRosol and Gases (MARGA) is a dedicated solution for on-line monitoring of atmospheric inorganic gases and aerosols in ambient air. A MARGA instrument was used lately in a large field campaign in the Southeastern US to measure the inorganic composition of aerosols and the key gases (HNO3, NH3, SO2) in equilibrium with each aerosol, enabling elucidation of aerosol ...

ASTM D6561 - 06(2011) standard test method for determination of aerosol monomeric and oligomeric hexamethylene diisocyanate (HDl) in air with (Methoxy-2–phenyl-1) Piperazine (MOPIP) in the workplace
HDI is mostly used in the preparation of paints. For the last ten years, the use of isocyanates and their industrial needs have been in constant growth. Diisocyanates and polyisocyanates are irritants to skin, eyes, and mucous membranes. They are recognized to cause respiratory allergic sensitization, asthmatic bronchitis, and acute respiratory intoxication (3-6). The American Conference of ...
