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 ...

Pulp and paper processing involves the use of wood as raw material to produce pulp, paper, cardboard and other cellulose-based products. Typical emissions generated from this type of manufacturing include Nitrogen oxides (NOx) sulfur oxides (SOx), carbon dioxide (CO2) and VOCs. Fine particulate matter (PM2.5) is also generated by this process, consisting of particles 2.5 microns in diameter or less which can penetrate the respiratory system and have a serious effect on health. ...

Particle sensor pm2.5 LD15 is a high-precision particle sensor based on the theory of laser MIE scattering. It can continuously collect and calculate the number of suspended particles with different particle sizes in air per unit volume, that is the concentration distribution of particles, and then convert to mass concentration. And output in the form of universal digital interface. learn ...

Smart homes and campuses are common concepts nowadays. Therefore, Air quality and ambient atmosphere are among the key criteria in choosing a residential area. An average person spends 10-14 hours of his day at home. Hence, it is necessary to ensure that it is clean, dust-free, and healthy. With increased environmental pollution, people are more inclined towards being aware of its impact on their health. Increased urbanization and auto mobilizing have made it prominently essential to keep their outdoor activities ...

In the production of metals from ore or recycled products there are many processes where pollutants form. Smelters require high amount of energy and depending on the source of this energy and where production takes place, energy consumption can also contribute to the amount of pollution in your flue gas. In processes for metals, the metal should be purified from unwanted materials. It is inevitable that these materials as well as small amounts of the metals end up in the flue gas. Our technology is unique in its ...

Students spend more than 25% of their day at School and University campuses. Poor air quality levels at the school campuses put the most vulnerable group at the highest risk. UNICEF and WHO have stated that young lungs are more susceptible to air pollution. Exposure at a young age when the immune system is weaker may lead to permanent respiratory health issues such as asthma and lung cancer. This renders air monitoring essential in and around the school and university ...

Mining and quarrying activities contribute to dust emissions from periodic explosions and heavy transportation vehicles. Subsequently, many industrial processes emit particulate matter mainly mineral, metallic, and wood dust. This phenomenon worsens air quality and increases the cases of respiratory ailments like asthma, bronchitis, etc. Dust measurement on these sites becomes critical as it can affect overall ambient air quality conditions. Construction activities are also one of the major sources of airborne ...

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. ...

Today, many industrial activities have significant environmental aspects. These aspects have environmental impacts that seldom create irreversible damage to mother nature. Lack of process control, irregular maintenance, or over-burdened design considerations give rise to many environmental violations. Air pollution is one key element that is often challenging for the organization to deal with. The absence of real-time air monitoring delays corrective actions and hence, affects the industry’s vision of ...

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 ...
