On PM 2.5 Filters, Let’s just clear the air between us; ok?

In the area of a former military building complex in the Chaoyang District of Beijing is a unique and thriving artistic community. In the middle of this art district, is a strange 7-meter tall tower shaped like an avant-garde metallic pineapple. Designed by Dutch artist Daan Roosegaarde, it is both an artistic creation and a functional tool meant to test a possible solution for ...

Indoor air quality problems

We have a number of employees in our office who have itchy, watery eyes, nasal congestion, headaches, lethargy and trouble concentrating. Most of the affected folks report they feel better at home and worse after they’ve been in the office for about an hour. We had the office tested for mold but nothing remarkable was found. What’s going on? While exposure to molds can certainly ...

Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

2013: a ‘perfect storm’ in air quality

As many countries fail to meet air quality targets and large numbers of premature deaths still result from air pollution, Jim Mills, a particulate monitoring specialist and Managing Director of Air Monitors, explains why 2013 will be a pivotal year. In November 2011 Janez Potočnik, European Commissioner for the Environment, expressed his determination to make 2013 the ‘Year of ...

Water Quality Monitoring and Testing Using an Environmental Logger

Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

Air quality monitoring and assessment programme for Botswana

An Air Pollution Monitoring and Surveillance Program (BAQMAP) is being developed, installed and tested for Botswana. The project is funded partly by NORAD and partly by the Botswana Government. The project is undertaken in a co-operation between Norwegian Institute for Air Research (NILU) in Norway and Department of Mines (DoM) in Botswana. NILU shall provide professional assistance in the ...

Confronting allegations of air quality non-compliance

A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...

Air quality issues drive vehicle alternatives

Vehicle exhaust systems remain a major source of air pollution in cities, despite the progress being made to reduce emissions from new models. Energy World takes a look at efficiency improvements, and the alternative fuel alternatives to petrol and diesel. In early April, the south of Britain woke to a hazy blanket of smog. A few weeks earlier, Paris had choked and spluttered through its own ...

Multi-Stage Air Quality Monitoring in the Workplace

CAS DataLoggers recently supplied the environmental datalogging solution for a factory with a small series of office rooms experiencing serious air quality issues. Employees reported headaches during the work day, indicating a possible lack of adequate ventilation. These workspaces were located next to the busy factory floor which caused an incidental ...

Ambient Air Quality Analysis of Toxic Gases and Priority

The EPA regional offices who continuously monitor ambient air quality have determined that combustion by-products and automobile exhaust make up the largest source of air pollution throughout the U.S., with more severe conditions existing overseas. Despite concerns about the conditions outdoors, air quality in the workplace and home environment receive even more attention. The EPA’s list of ...

Rough set-based regionalisation in air quality monitoring

Regionalisation is to organise a large set of spatial objects into spatially contiguous regions despite optimising the homogeneity of the derived regions, while representing social and economic geography. To confront this problem, it is necessary to classify the regions to form groups that are homogeneous in air quality attributes. It is to develop a system that applies data mining techniques to ...

The challenges and benefits of local air quality monitoring

A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

Air quality Monitors Track Pollution Hot-Spots

Situated in the south west of Wales, in a largely rural area bordering the Brecon Beacons, Carmarthenshire’s air quality is predominantly good. However, there are areas of concern where major roads pass through some of the County’s larger towns, including Llanelli, Carmarthen and Llandeilo, where air quality is dominated by the effects of road traffic. The County Council is therefore ...

Importance of Air & Water Testing in Indoor Pools

Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

Reporting and exchanging air quality information using e-Reporting

A number of EU legal instruments require EU Member States to monitor and report air quality data. This information is collated, analysed and disseminated by the European Environment Agency (EEA). At present much of the data is reported electronically by countries in data flows required under a specific legal instrument. As a result, reporting on air quality is not always integrated across all ...

Considering ecological formulations for estimating deposition velocity in air quality models

A dry deposition modelling approach that includes surface feedback through photosynthesis relationships was recently developed. A canopy photosynthesis model is dynamically coupled to an atmospheric model with prognostic soil hydrology and surface energy balance. The effective surface resistance is calculated for a realistic and fully interactive estimation of gaseous deposition velocity (Vd). ...
