It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle ...

There can be several purposes for monitoring the air quality in an urban area. If the aim is to assess what the residents are exposed to in the worst case, a so-called street-level monitoring is carried out. If the aim is to monitor the general levels of air pollution and follow up long-term trends, you should instead monitor further away from the busiest roads, for example at roof level. ...

How clean is the ambient air in our cities? A common strategy for monitoring the air quality in a city is to measure at ground level where people actually live and are at risk of exposure to air pollution. Often, there is also a requirement that the measurements are made in a place where you can expect the air pollution to be relatively high, which often means along one of the city's busier streets. Limit values for air quality often apply precisely to these locations. OPSIS offers several monitoring systems for ...

Air pollution at regional and national scales. It is important to monitor air pollution where many people stay, i.e. in cities and especially at street level. In order to better understand where the pollution comes from, a so-called background monitoring may also be needed. Then the monitoring station is placed in the countryside, at a great distance from obvious sources of the ...

Particle size, particle concentration and other physical characterization analyses are critical to many environmental applications. Regulatory agencies in the environmental sphere demand strict compliance to standards and discharge regulations. Physical testing of samples for parameters such as particle size and concentration can give insight to the process control engineer on how effective and compliant a discharge handling system is operating. Particulate loading from both air emissions and waste water discharge ...

Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly ...

SMOG: Smog is a type of air pollution and comes from the words smoke and fog, which refers to smoky fog. This air pollution consists of nitrogen oxides, sulfur oxides, ozone, smoke or dirt particles and even less visible particles. Smog arises from carbon, vehicle and industrial emissions as well as forest fires etc. Today we also know that air pollution can react in the atmosphere with sunlight and form new pollutants sk. photochemical smog. Smog is very toxic and can cause serious illness, shortened life or ...

Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels. Common air monitoring applications include: Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination. Asbestos sampling and analysis ...

The emission challenge is significant to ETG Risorse e Tecnologia. For years it has been engaged in providing instrumentation and support to authorities and companies operating in the environmental sector. Climate change is a scientifically established reality, as is its anthropogenic origin; emissions of pollutants into the atmosphere are one of its leading causes. Their monitoring - in addition to being mandatory - allows their level to be kept under control. ETG fully supports the Green Deal and the European ...

Air quality monitoring may involve measuring particle mass (PM), particle number concentrations (PN), particle size, or collecting particles for later chemical analysis. Air quality monitoring efforts are usually driven by governmental regulation, but may also be motivated by a neighborhood concern or scientific interest. These measurements are performed by researchers in industries or institutions, but they may also be performed by local advocacy groups. When combined with other information (such as weather data, ...
