MCERTS for Praxis/Urban Air Quality Monitor
South Coast Science’s Praxis/Urban has now been awarded MCERTS for indicative measurement of dust in ambient air (PM2.5 and PM10). You can see the list of certified devices on the CSA website here, you can also view our certificate which includes notes on the product and its usage. The certification process is also underway for the Praxis/Cube and it’s anticipated that full MCERTS ...

Different types of urban air quality monitoring locations
The 2008/50/EC Directive’s sampling point requirement introduces and examines the main question of when air pollutants should be measured. The Directive further examines different types of urban air quality monitoring locations: where should these monitoring stations be located and what is the requirement of the monitoring locations? Read on more to learn about the different monitoring ...

Near-field geometry effects on urban street canyon measurements for model validation
Selection of numerical urban pollution dispersion models for regulatory purposes entails reliable prior validation against either physical modelling or field measurements. It is shown that an asymmetric geometry of the urban street canyon, in which measurement takes place, induces persistent gradients in pollution dispersion within it, irrespective of the wind vector meandering above the roofs. ...

Variability of PM10 concentrations dependent on meteorological conditions
The influence of atmospheric exchange conditions on near-surface PM10 concentrations is analysed for four cities in the South-West of Germany in the period from 2001 to 2005. For each city, the PM10 data originates from roadside stations and Urban Background (UB) stations, that is, two types of official urban air quality monitoring stations characterised by different emission situations. The ...

Urban air quality monitoring at Kars, Turkey - Case Study
Overview Kars Smart City monitored the urban air quality and environmental health by installing Oizom Polludrone – Online Pollution Monitoring System. In addition to Air Quality monitoring, the Polludrone also monitored the city’s urban weather conditions like temperature and humidity. The real-time data was dispersed to the mass audience through visual messaging ...

An inverse modelling approach for estimating vehicular emissions in urban coastal areas of the Messina Strait
The CALPUFF modelling system was used to predict dispersion of contaminants emitted from industrial, naval and vehicular sources in the Strait of Messina area (Italy). This region is of particular interest in that it relates to the construction of the Messina Bridge, the road infrastructure linking the Italian mainland and Sicily. The domain includes two cities, i.e., Messina and Reggio Calabria, ...

An ambient air quality monitoring network for Buenos Aires city
This paper proposes an objective methodology for designing a multi-pollutant urban air-quality monitoring network to detect concentrations greater than reference concentration levels (CL). The network design includes both air quality simulation and an objective analysis based on monitoring tasks. The proposed methodology is applied to the city of Buenos Aires. Pollutants of concern are nitrogen ...

Urban air quality sensors: More information, better quality of life in cities
The city of Donostia-San Sebastián seeks to make the most of all the advantages derived from ICT technologies. From an air quality perspective, the periods of high pollution are unusual, since its coastal location facilitates the dispersion of pollutants. This city holds a network of 6 monitoring stations which belong to the Basque Government Air Quality Network, which ...

Analysis of an anomalous case of high air pollution concentration in Turin after a foehn event
A case of unusually high concentrations of some urban air pollutants (CO, NO, SO2) in Turin (Northwestern Italy) is presented. This episode occurred during the late afternoon of 7 November 1995. This day was characterised by a strong northern foehn event in the morning, which followed the passage of a cold front. The analysis has been carried out by means of data derived from the urban and ...

Hybrid Air Quality Monitoring Network – The future of urban monitoring
Rapid urbanization, industrialization, and a rise in vehicular pollution have severely affected air quality in cities. With growing concerns about air pollution and cascading effects across the population, air pollution is emerging as a significant problem. Vehicular pollution, road dust, construction, and industrial pollution are some of the major sources responsible for air pollution in Indian ...

Developing a public information and engagement portal of urban waterways with real-time monitoring and modeling
Waterways can contribute to the beauty and livelihood of urban areas, but maintaining their hydro-ecosystem health is challenging because they are often recipients of contaminated water from stormwater runoff and other discharges. Public awareness of local waterways’ health and community impacts to these waterways is usually poor due to of lack of easily available information. To improve ...

Receiving water body quality assessment: an integrated mathematical approach applied to an Italian case study
This study presents a basin-scale approach to the analysis of receiving water body quality considering both point and non-point pollution sources. In particular, this paper describes an extensive data gathering campaign carried out in the Nocella catchment, which is an agricultural and semi-urbanised basin located in Sicily, Italy. Two sewer systems, two wastewater treatment plants and a river ...

Analysis of local concentration gradients in complex built environments: implications for Air Quality Management Areas
This paper reviews the existing guidance on placement of permanent air quality monitoring stations within urban areas and suggests the principles for a new, performance-based guidance. An integrated air quality model has been developed and validated for the designated Air Quality Management Area (AQMA) located in Glasgow City Centre to analyse the importance of local concentration gradients on ...

Air Quality Monitor in Brighton picked up PM1 plume from French Wildfires
Back at the end of July, two South Coast Science Praxis monitors picked up some unusual data. The monitors are installed at Preston Circus, Brighton and the data dashboard for each shows a diffuse and slowly shifting plume of particulate matter (PM1) in the evening on 20th and morning of 21st July. It wasn’t until one of the team put this together with a distinct smell of damp wood smoke ...

Spatial and temporal differences of Particulate Matter in Berlin
Particulate Matter (PM) is still a problem in urban areas. The concentration of PM in Berlin and its variability is the subject of this study based on data of six official PM10 monitoring stations and a measuring program carried out by the Institute of Geography covering PM2.5 and coarse PM measurements at 19 sites, distinguished between traffic related and urban background sites. The impact of ...

Automatic, semi-automatic and manual validation of urban drainage data
Advances in sensor technology and the possibility of automated long distance data transmission have made continuous measurements the preferable way of monitoring urban drainage processes. Usually, the collected data have to be processed by an expert in order to detect and mark the wrong data, remove them and replace them with interpolated data. In general, the first step in detecting the wrong, ...

A comparative assessment of institutional frameworks for managing drinking water quality
The global burden of disease attributable to contaminated drinking water calls for effective strategies for ensuring drinking water quality. To characterize institutional and policy approaches towards water quality management, we compared national and sub-national institutional frameworks for drinking water provision and management in nine developing countries, focusing on roles, responsibilities ...
