Real-time roadside air quality monitoring

Air Quality & Dust

Jacobs; a global environmental consultancy is using real-time air quality monitors in combination with traffic sensors to help understand the high levels of NO2 on the A132 East Mayne Road in Basildon, Essex. Essex Highways is a Strategic Partnership between Ringway Jacobs and Essex County Council.

Air quality modelling and diffusion tube monitoring of annual mean NO2 concentrations on East Mayne, Basildon indicate that NO2 concentrations are above 40 µg/m3. NO2 concentrations are heavily influenced by NOx emissions from road traffic and therefore it is important to evaluate the correlation between traffic and NO2 concentrations.

The Basildon Air Quality Project

The project aims to reduce exceedances of nitrogen dioxide (NO2) to below the limit values within the shortest possible time, at those locations within Basildon that have been identified both on the national Pollution Climate Map (PCM) and at additional locations that were identified following local modelling. Therefore, the primary objective is to bring NO2 levels into compliance with the EU Limit Value of 40 μg/m3.

Remote Monitoring Solution

Several Aeroqual AQS1 real-time monitors have been installed in the area to monitor NO2 concentrations. The key for this project is to correlate the high-resolution data from the air quality monitors to the traffic sensors.

The information will give an in-depth understanding of the causes of elevated NO2 concentrations on East Mayne. Real-time data from the air quality monitors will be available on Aeroqual Cloud. The web-based platform will allow the project managers to access the real-time data and correlate the readings from all the 7 units.

SiteSens Noise & Dust Monitor with MCERTS

Air Quality & Dust

The brilliant new system from Sonitus is designed to record Noise & Dust measurements at the same time AND PM10 & PM2.5 particulates are recorded simultaneously AND the dust monitor is certified to MCERTS indicative requirements – Impressive !!

Sonitus systems are a high-tech company founded by the acclaimed research department of Trinity College, Dublin. They are dedicated to smart solutions for accurate and highly automated monitoring applications.

The latest product from Sonitus is the DM30. This new monitor uses communication and processing technology from the established EM2030 noise monitor, which is designed from the bottom up as an automated monitor. The DM30 keeps the noise capability and adds dust/particulate monitoring to run in parallel. This dual functionality saves considerable cost, as a single monitor can do the job of two! This means a single cabinet, SIM card/ data subscription and a power connector.

The dust monitor provides accurate data which has been certified to MCERTS indicative requirements for both PM10 and PM2.5 and the system logs these channels simultaneously with PM1 (not MCERTS). The certification range is from 0 to 200 ug/m-3 for both PM2.5 and PM10 – which covers the limit of the construction code of practices. PM10 is the primary channel for construction dust monitoring but PM2.5 is now often asked for by local authorities on large scale projects.

To ensure the sensor and systems measure to the highest standards Sonitus have invested in a state-of-the-art test facility for air quality research, development, and ongoing calibration.

The DM30 has a built-in heater to dry the air sample before it goes through the particle counter. This ensures accurate measurements even in high humidity environments such as fog. Even with the heated inlet, efficient electronics make it possible to run the monitor on a 12v battery pack for a week or more – It also can be powered by solar and hydrogen generating systems.

The system is modular and can be ordered as a dust monitor or as a combined noise and dust monitor, and you can also integrate an anemometer for wind speed and direction. The DM30 automatically sends the data to Sonitus cloud for reporting, alerting and administration of your projects in an easy to manage platform.

Typically, noise and dust monitoring are required at the same location for construction projects and the DM30 saves space, money, and time.

Why you should be monitoring NO2 on construction and demolition sites

Air Quality & Dust

Construction sites can generate many types of pollution. If you asked somebody to describe what they thought were the most common types of waste, they would point to things like noise, vibration, and dust pollution.

However, one of the most common problems people experience on demolition and construction sites is the presence of nitrogen dioxide and fine dust particles, known to many as particulate matter.

With roughly 7% of all NO2 production in London generated by Non-Road Mobile Machinery (NRMM), it’s never been more important to engage in proper dust monitoring and keeping an eye on MO2 levels.

How do construction sites make NO2?

So, the burning of fossil fuels creates oxides of nitrogen. This is what we call NO2, but what we’re actually interested in is NOx. This is a combination of nitric oxide and nitrogen dioxide. NO2 is primarily the concerning element due to the health impact that it has.

However, nitric oxide can convert to NO2 in the air, so if we’re going to manage the concentrations of NO2 properly, we need to control NOx emissions!

What are the health effects of NO2?

So, it is important to recognise that there are short-term consequences of NO2 and long-term consequences. Short-term impacts can include airway inflammation in healthy people and increased respiratory distress in asthmatics.

Studies have also shown that there is a connection between short-term exposure to NO2 and increased admission to hospitals for respiratory illness.

Furthermore, NOx can mix with ammonia, moisture and other compounds in the air to form smaller particles that can easily enter the sensitive parts of the body.

Recent research conducted on the subject shows that children who were exposed to air pollution in London had a poor lung capacity and were at risk of developing lifelong breathing problems.

Thoughts on NO2 measurement

Dust monitoring is a good way of gauging how much NO2 is present in the air.

There are special devices which have an actively pumped airflow which allows them to sample NO2 in the atmosphere to get a proper understanding of how many key pollutants exist on the site.

The data is then stored and uploaded to the cloud, which can be accessed by anybody.

There are also passive systems to consider that collect and store information over the course of a month.

We usually measure NO2 concentrations as something over an hour period, and we use it frequently for construction projects during working hours in this way.

Final thoughts

It’s important to measure NO2 concentrations to gauge how harmful the exposure is to the workers on the construction site. Long-term exposure to this chemical can be dangerous, which is why it is important to keep an eye on it.

It’s often recommended that construction sites get real-time figures on NO2 production, as well as having the passive data gathering for a month. The two working in tandem can help to make a comprehensive analysis and be good for dust monitoring.

Understanding the impact of wood burner emissions: monitoring dust in communities

Air Quality & Dust

Introduction:

In recent years the use of log burners has attracted a lot of attention from Air Quality groups. While the evidence for & against log burners are varied, it is certainly compelling enough to require careful consideration. Local authorities across the UK have undertaken air quality monitoring to see the potential impact in their regions.

How you can benefit from our dust and weather station

Air Quality & Dust

Monitoring weather conditions and dust levels at construction sites is essential for ensuring

AQS station with weather

worker safety, minimising environmental impact, and maintaining compliance with regulations.

Upwind and downwind monitoring is particularly important for managing dust emissions, as it helps identify if the pollution is being generated on-site or blowing into site and can also help reducing the number of monitors required on site.

Upwind and Downwind Monitoring:

  • Upwind Monitoring: Captures baseline dust levels before they reach the site, indicating the quality of incoming air.
  • Downwind Monitoring: Measures dust levels after the air has passed through the site to assess the impact of construction activities.

The additional benefit of the local weather monitoring is to ensure safety of works when working at height. High winds can make working at height hazardous, affecting the stability of scaffolding, cranes, and other equipment, as well as increasing the risk of workers falling or being struck by flying debris.

Here are important considerations and guidelines for managing wind conditions at construction sites: 

Scaffolding

Wind-Related Hazards

Stability of Structures:

High winds can destabilise scaffolding, cranes, and temporary structures, leading to collapse or tipping.

Worker Safety:

Wind can make it difficult for workers to maintain balance, increasing the risk of falls.

Wind-borne debris can strike workers, causing injuries.

Equipment Operation:

Operating cranes and lifts in high winds can be dangerous due to the potential for swinging loads and reduced control.

RAAC in UK schools: the urgency of rebuilding with environmental monitoring

Air Quality & Dust

In recent years, the presence of Reinforced Autoclaved Aerated Concrete (RAAC) in UK schools has raised significant concerns. RAAC, a lightweight form of concrete used extensively from the 1950s to the 1980s, has been found to deteriorate over time, posing structural risks.

As the UK government and educational authorities embark on rebuilding and refurbishing affected schools, incorporating robust environmental monitoring becomes crucial.

The RAAC Crisis in UK Schools

RAAC was initially favoured for its cost-effectiveness and ease of use. However, over decades, the material’s limitations have become apparent. RAAC is prone to moisture ingress, which can significantly weaken its structural integrity. In schools, where the safety of students and staff is paramount, the presence of RAAC has prompted urgent action.

The UK government has recognised the severity of the RAAC issue and launched initiatives to address it. This includes funding for inspections, temporary accommodations, and ultimately, rebuilding or refurbishing affected structures. While immediate safety measures are critical, the long-term solution lies in comprehensive rebuilding programs.

The Role of Environmental Monitoring in Rebuilding

As schools undergo rebuilding, environmental monitoring becomes an essential component of the process. Environmental monitoring involves the continuous assessment of environmental parameters to ensure that construction activities do not adversely affect the health and well-being of students, staff, and the surrounding community.

Key Aspects of Environmental Monitoring:

Noise and Dust Monitor powered by solar energy

Air Quality Monitoring:

  •  Dust and Particulate Matter: Construction activities can generate significant dust, affecting air quality. Using our dust monitors will ensure that dust levels remain within safe limits.
  • Volatile Organic Compounds (VOCs): The use of certain construction materials can release VOCs, which need to be monitored to prevent respiratory issues.

Construction Noise: High noise levels from construction can disrupt the learning environment and impact health. Monitoring helps in implementing noise control measures.

Noise monitor powered by battery

Implementing environmental monitoring during the rebuilding process offers numerous benefits:

  • Health and Safety: Protects the health of students, staff, and the local community by ensuring a safe construction environment.
  • Compliance: Helps schools comply with environmental regulations and standards.
  • Community Confidence: Demonstrates a commitment to environmental responsibility, building trust with the community.
  • Sustainable Practices: Promotes sustainable construction practices, contributing to long-term environmental stewardship.

The presence of RAAC in UK schools necessitates urgent rebuilding efforts to ensure the safety of students and staff. As these rebuilding projects commence, incorporating comprehensive environmental monitoring is not just a regulatory requirement but a moral obligation. By prioritising environmental monitoring, schools can ensure a safe, healthy, and sustainable learning environment for future generations.

The challenge posed by RAAC in UK schools is significant, but with proactive measures and a commitment to environmental monitoring, it is an opportunity to rebuild better and safer educational spaces.

Our range of noise, vibration, dust and air quality monitors are able to assist contractors in maintaining safe practice on projects.

Risks of aspergillus in construction & demolition & how to mitigate them

Air Quality & Dust

Aspergillus is a micro-organism that can be found during demolition and construction works and is a health risk to humans. Aspergillus is a fungus that can cause significant health problems when breathed in during certain construction work.

It is typically 2 – 3.5 μm in size, small enough to enter the airways.

Aspergillus is a mould commonly found in many indoor environments such as old & dilapidated building. Construction/demolition activities on sites such as these can release the fungal spores into the air increasing the exposure. It is possible that Aspergillus can also be found outdoors in damp and garden environments.

It is critical on construction and demolition projects that we control the risks and exposure to workers on site while they work. There are prevent measures which can be carried out to control the exposure to Aspegillus.

First, carry out risk assessments and controls to ensure workers & visitors are protected and a plan is in place.

Secondly, we must ensure the particle doesn’t become airborne by using dust control along with real-time dust monitors to monitor the levels of air particles and sizes throughout the project.

Thirdly, install proper ventilation systems which are maintained, and contamination free.

Workers with damaged lungs or a weakened immune system can get several diseases (called Aspergillosis or farmer’s lung) if they inhale these spores. The symptoms of ASPGILLOSIS are a cough, shortness of breath and wheezing. More symptoms can be found on the NHS website.

Dust particles of 2 – 10  μm can be measured using dust detection analysers. Campbell Associates offer several solutions for this.

Such as our Aeroqual Ranger using a PMX dust monitor module which will measure TSP, PM10, PM4, PM2.5 & PM1. This handheld device allows the operator to walk around the site and establish the level of dust particles in each cubic metre of air as the unit μg/m3.

If continuous monitoring should be carried out then we would deploy our MCERTS Certified (by the Environment Agency) PM10 & PM2.5 dust monitor.

The DustSens DM30 monitor provides real-time data alerts and mean average readings into a cloud platform. SMS & Email alerts are setup when exceedances have been hit, alerting workers on site to take action.

What can I do to stop mould growth in the first place? 

The EniSens DL40 is a low power, automated data logger for measuring temperature and relative humidity. 

Mold thrives in humid, warm environments, typically when relative humidity is over 60% and temperatures are between 20-30°C (68-86°F). By using a logger, you can monitor the conditions and take steps to keep the humidity and temperature within ranges less favourable for mold.

Using a logger enables us to monitor patterns and detect spikes in humidity and temperature, especially in mold-prone areas. By setting threshold limits, such as 60% relative humidity, we can send email or SMS alerts to workers or environmental managers when levels exceed safe limits.

This allows site supervisors to take corrective actions, like increasing dehumidification or improving ventilation, to prevent mold growth. When water suppression is used to control dust levels, it may raise relative humidity and lead to damp areas where mold could develop later.

What is MCERTS and Why do you need a MCERTS approved Dust Monitor?

Air Quality & Dust

MCERTS is the certification scheme created by The Environment Agency for equipment, personnel and organisations. The aim of this scheme is to provide delivery vehicle for compliance with European Directives by regulating industrial emissions, monitoring data, equipment and personnel.

MCERTS certification indicates that the performance of the monitoring equipment has been tested under mixed environmental conditions and ensures that the accuracy, reliability and consistency meet the specifications set by the Environment Agency. 

When using equipment for monitoring  air quality/dust for regulatory purposes, it’s crucial to use equipment with MCERTS.

Dust particles can be spilt it various size categories for monitoring. Currently, the focus is PM10 and PM2.5 sized particles which refers to the size and diameter of the particle.

PM10 = 10 um in diameter

PM2.5 = 2.5 um in diameter.

PM = Particle Matter

What are the effects of breathing in dust (Particle Matter)?

PM10 particles can be inhaled into the lungs and cause adverse health effects.

PM2.5 has been linked to premature death, particularly in people who have chronic heart or lung diseases, and reduced lung function growth in children. They cause lung irritation and can worsen asthma and other related medical conditions. Long term exposure has more severe effects such as lung cancer and chronic bronchitis.

What does limits should I implement on my construction or demolition site?

According to IAQM guidance for construction and demolition sites and a recent report by King’s College that evaluated nine construction sites, a Site Action Level of 190 µg/m³ for PM10, measured as a 1-hour mean, is recommended.

Using MCerts-certified dust monitors focusing on PM10 particles, which are coarse particles measuring 10 µm in diameter and we are measuring dust deemed to cause significant health risks.

How can I measure PM10 & PM2.5?

Campbell Associates offer several solutions for MCERTS dust monitoring.

The DustSens DM30 monitor has MCERTS for both PM10 & PM2.5.  It provides real-time data alerts and mean average readings into a cloud platform. SMS & Email alerts are setup when exceedances have been hit, alerting workers on site to take action.

The Dust Sentry is another real-time monitor which is available in versions, with a MCERTS certificate for PM10 only & PM10/PM2.5. The monitor can also be upgraded to measure gases like NO2 and VOCs. Please get in touch to discuss your project requirements.
