In volcanic settings like Stromboli, robust inlet design and uninterrupted sampling are essential to resolving short-lived degassing transients and diffuse CO2 anomalies against a geochemical background.Complementary instruments are deployed to broaden analytical coverage. The portable pQA system provides field-deployable, battery-powered mass spectrometric analysis for on-site ...
From a health and safety point of view, it is therefore important to monitor the HF levels in connection with the production process, but it is also of interest to measure emissions of HF to the environment. Such emissions can occur both via flue gas ducts and in the form of diffuse emissions through the roof ventilation of the ...

Since the first meeting in 1997, the CEM exhibition and conference has established itself as Europe’s leading event for air emission and air quality monitoring. The 16th International CEM meeting will take place from 24th to 26th September in Slovenia's vibrant capital, Ljubljana. Topics of CEM 2025 will include: Air quality networks and sensors Biogenic ...
It is therefore essential to minimize planned emissions to air and to protect humans and the environment around the industries in case of unplanned releases of process gases. ...

Therefore, stainless perforated metal is frequently used for diffusing sound, soundproofing, and reducing acoustic emissions. This performance helps people or workers limit the health effects of noise. 6. ...
While not specifically focussing on the environmental risks associated with methane gas and nitrous oxide emissions from networks, there is no doubt that from an environmental governance perspective the management of fugitive gas emissions from network systems is a significant greenhouse issue. It is over ten years since the Urban Water Security Research ...
LOCATION Pamplona, Spain SOLUTION Industrial perimeter & Odours SECTOR Smart Environment PRODUCT Kunak AIR A10 Challenge For the last few months, we have been collaborating with the management body of the Arazuri wastewater treatment plant (EDAR of the Pamplona District) to implement a system for measuring environmental variables, improve decision-making and reduce the impact that bad ...
Incidents related to olfactory pollution can cause physical discomfort in people. Although some emissions come from natural sources, others are related to specific industries or processes. Establishing an early-warning perimeter system, based on sensors, for leaks and diffuse emissions can help to reduce odoriferous pollution episodes. ...
The CEM events are attended by some of the world’s leading experts in emissions monitoring as well as the operators of European processes looking for the latest help and advice on regulations, standards, methods and technologies. ...
The statistical model MESAW (Matrix Equations for Source Apportionment on Watershed) was used to estimate the diffuse unit-area source emission coefficients of nitrogen in Estonian rivers. ...
Excessive CO2 emissions in the atmosphere from anthropogenic activity can be divided into point sources and diffuse sources. ...

At the latest since the Volkswagen emission scandal and the fine dust alert in Stuttgart, the topic gained presence. It is a fact that the emission of fine dust and nitrogen oxide in exhaust gases is not entirely caused by road transport vehicles. ...
Land-based total nitrogen (N) loadings to Danish coastal waters have been markedly reduced since 2000. This has been achieved by general measures reducing discharges from all point sources and N leaching from farmed land supplemented with more local and targeted mitigation measures such as restoration of wetlands to increase the catchment-specific N retention. In the catchment of River ...
This study aims to identify major diffuse emission sources in the technosphere through a comprehensive substance flow analysis of Ag in Stockholm, Sweden. ...
Keeping the street geometry acceptable in an urban area has become an important task to improve the air quality. Gaseous emissions from vehicles increase the incidence of a variety of human health problems. ...
Emissions of pollutants and nutrients are causing several problems in aquatic ecosystems, and in general an excess of nutrients, specifically nitrogen and phosphorus, is responsible for the eutrophication process in water bodies. In most developed countries, more attention is given to diffuse pollution because problems with point pollution have already been ...
Here are five big reasons we should care about fugitive methane emissions: 1) Emissions Are Still Too High. Methane is a potent greenhouse gas and a key driver of global warming. ...
The SILAM model with built–in isoprene and monoterpene emission module from natural sources was run for May to August 2006 in Baltic Sea region. ...
This study aims at developing and evaluating a model for simulating stormwater flows of two groups of organic pollutants; nonylphenols and phthalates. Sources, emission patterns and environmental fate were examined to create a model framework for the organic contaminants. ...
The objectives of this study were to identify emission sources of phthalates, nonylphenol and its ethoxylates (NP/EOs) in urban stormwater, and to quantify the substance fluxes from the source to the stormwater system, using the methodology of substance flow analysis (SFA). ...
