Straightforward determination of anhydrosugars in aerosols

Metrohm presents a new method for the sensitive and robust routine determination of the «smoke markers» levoglucosan, mannosan and galactosan in aerosols. The method couples ion chromatography with a highly sensitive pulsed amperometric detector (IC-PAD) and provides a simple and less expensive alternative to GC/MS. As such, it facilitates research into the effects of biomass burning aerosols on ...

ASTM D6552 - 06(2011) standard practice for controlling and characterizing errors in weighing collected aerosols

The weighing of collected aerosol is one of the most common and purportedly simple analytical procedures in both occupational and environmental atmospheric monitoring (for example, Test Method D4532 or D4096). Problems with measurement accuracy occur when the amount of material collected is small, owing both to balance inaccuracy and variation in the weight of that part of the sampling medium ...

Rainfall can release aerosols, study finds

Original story at MIT News Ever notice an earthy smell in the air after a light rain? Now scientists at MIT believe they may have identified the mechanism that releases this aroma, as well as other aerosols, into the environment. Using high-speed cameras, the researchers observed that when a raindrop hits a porous ...

New approach improves accuracy of aerosol measurements on cloudy days

Satellites taking atmospheric measurements might now be able to see blue skies as clearly as optimists do. Researchers have found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases. The result might lead to more accurate estimates of the amount of sunlight penetrating the atmosphere. Because clouds represent one of the ...

PILS-IC-VA: semi-continuous determination of anions, cations & heavy metals in aerosols

Metrohm presents PILS-IC-VA, a new instrumental approach coupling a Particle-Into-Liquid-Sampler (PILS) to a dual-channel ion chromatograph (IC) for measuring aerosol anions and cations and a voltammetric measuring stand (VA) to determine the heavy metals. PILS-IC-VA is a powerful tool to capture the short-term impacts of air pollution as it allows the near real-time determination of the aerosol ...

Indian PTR-MS collects first VOC data from Indo-Gangetic Plain

Prof. Vinayak Sinha lives and does his research in a region called the Indo-Gangetic Plain (IGP). Home of one seventh of the world’s population and as a fertile region, it sustains agricultural food crop production for much of South Asia, yet it remains one of the most under-studied regions of the world in terms of atmospheric composition and chemistry. One of Prof. Sinha’s goals is ...

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 ...

Aerosolv

Having problems getting rid of spent aerosol cans? Did you know that even if you think the can is empty, it is still considered hazardous waste? For safe and quick disposal of aerosol cans, the Aerosolv is the only solution. The Aerosolv punctures the aerosol can and evacuates the contents into a 55-gallon drum. The liquid is collected in the drum ready for disposal, while a ...

Outpacing climate change with atmospheric research collaboration

Tiny particles in air called aerosols create smog, seed clouds, and control how much of the sun's heat makes it through the atmosphere. And yet these particles are the least understood aspect of climate research. Now, two research institutions are working together to tackle the role of aerosols in climate change -- specifically how aerosols from pollution, oceans and wildfires contribute to ...

Tracking down the menace in Mexico City smog

A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in Mexico City may not come from motor vehicles but instead originates with industrial sources – and that the culprit may be garbage incineration. The MILAGRO Campaign (Megacity Initiative: Local and Global Research Observations) monitored air quality in the Mexico ...

Can rain clean the atmosphere?

Original story at MIT News As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, ...

Air pollution cutting China`s `vital` rain

China's increasing air pollution has cut the light rainfall essential to the country's agriculture over the last 50 years, new research suggests. The research, published in the Journal of Geophysical Research last month, is based on rainfall data collected from weather stations across China. The number of light rain days — those with precipitation of less than ten millimetres — in northeast and ...
