Particles as a Part of Air Quality Monitoring
Join us for a 45-minutes webinar that emphasizes the need for particle number (PN) based counting and sizing solutions complimentary to the widely used particle mass (PM) sensors, especially for the size range of ultrafine particles (UFP < 100 nm). While monitoring different emission sources continuous sampling and transportation of the aerosol size fractions need to be taken into ...

Practical Aerosol Science - A short course in aerosol theory and measurement
A 3-day course in practical aerosol science is being run between 8th and 10th June, at the University of Manchester. The course aims to deliver an introductory understanding of the challenges faced with aerosol measurements. Sampling ambient particles can be extremely challenging and answering a simple question like 'how big is the particle' depends on what instrument was used to measure it. The ...

What are ultrafine particles, and how can you include size distributions and concentrations as part of routine air quality monitoring?
Ultrafine particles (UFP) are particles that are too small to contribute appreciably to mass-based measurements, but are present in ambient air. While regulations focus on PM and neglect ultrafine particle number concentrations, a growing body of research is investigating the ultrafines present in the air we breathe. The findings of this research motivate the measurement of ultrafine particles at ...

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 ...

Modern vehicles vs toxicology
Exhaust emissions — fuel alternatives and toxicology A lot of research followed by industrial innovations and stricter regulations have reduced urban pollution in many European cities. But the last few months have shown us what clean air really means and that we ought to do even better. Regulations, and development due to the regulations, have decreased vehicle emissions remarkably. Still ...

ASTM E2144 - 11 Standard Practice for Personal Sampling and Analysis of Endotoxin in Metalworking Fluid Aerosols in Workplace Atmospheres
Endotoxins in metalworking fluid aerosols present potential respiratory health hazards to workers who inhale them. Therefore, a consensus standard is needed to provide reliable data on workplace airborne endotoxin concentrations where metalworking fluids are used. This practice for measuring airborne endotoxin concentrations in metalworking fluid atmospheres will ...

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 ...

Launch of Metrohm AeRosol Sampler `MARS`
With the intensification of air pollution, the monitoring of the chemical composition of aerosols (particulate matter «PM») is becoming more and more important. However, traditional filter membrane sampling methods are time-consuming and labor-intensive, and the collected samples need manual pretreatment. The usual sampling period is several days, which cannot provide higher temporal ...
