AQE AIR QUALITY & EMISSIONS 32


ENVIRONMENTAL EVENTS LIVE AGAIN IN 2022!


Following last year’s hugely successful virtual events, the organisers of AQE and WWEM are delighted to announce that the 2022 events will take place live at the Telford International Centre on 12th and 13th October. Both events cover regulations, standards, process control, pollution prevention, test methods and monitoring, with AQE, the Air Quality & Emissions show, addressing outdoor and indoor air quality, as well as industrial emissions, and WWEM focusing on Water Wastewater and Environmental Monitoring in both process water and natural water resources.


“We are absolutely delighted to be able to return to live events again,” says organiser Marcus Pattison. “Last year’s virtual events enabled a broader group of people to access the presentations, but the pandemic prevented all of us from exploiting the advantages of face-to-face meetings. As focused events, WWEM and AQE therefore offer everyone the opportunity to meet a lot of key people in a short space of time, whilst accessing an enormous amount of the latest information.”


Both of the AQE and WWEM conferences are supported by a comprehensive range of seminars, and two major international exhibitions featuring most of the world’s leading suppliers of environmental monitoring equipment, analytical testing instrumentation and support services.


Registration for both AQE and WWEM is free and available from www.ilmexhibitions.com. By registering prior to the event, visitors will be entitled to free parking, free refreshments and complementary access to both events.


AQE 2022


The two main components of AQE are air quality (indoor and outdoor), and industrial emissions. The air quality programme has been confi gured by Jim Mills, a well-known fi gure in the sector and now and independent consultant with Scotswolds Ltd. Presentation titles, abstracts and author details are published on the AQE website. However, the main themes of the air quality sessions will cover four key issues, which can be summarised as follows:


AQE – air quality monitoring 1. Regulation and Policy


Speakers from government/regulators will summarise the implications of the Environment Act 2021 with regard to ambient air quality, explaining the targets and timelines that have been specifi ed. For example, the Act establishes a legally binding duty to bring forward at least two new air quality targets in secondary legislation by 31 October 2022. The proposed targets relate to PM2.5 with a 2040 objective, which is a concern for many stakeholders. These issues will be addressed by subsequent speakers from philanthropic organisations which are engaged in air quality matters by funding research, undertaking monitoring and other initiatives, whilst also


lobbying policy makers, seeking to improve environmental legislation and hold the government to account.


The UK’s Air Quality Expert Group (AQEG), provides advice to the UK government, and one of their members will provide an update on current knowledge on air pollution in relation to concentrations, emission sources and the characteristics of air pollutants in the UK.


The fi nal presentation of this session will be given by a speaker from NPL, the UK’s National Physical Laboratory. They will describe a new state-of-the-art facility for testing sensor technologies, and outline the latest work on the standards and methods that underpin air quality science.


2. Measurement technology


This session will provide the latest information on developments in the techniques and technologies employed on the measurement of air pollution. This will include a report from QUANT programme, which has conducted a real-world open and traceable assessment of low-cost sensors and sensor networks, and their calibration, in order to better understand their performance.


One of the speakers will focus on the measurement of Black Carbon; a pollutant which has a signifi cant impact on both air quality and climate change. This presentation will outline the latest advances in small sensor technology for Black Carbon measurements.


During the COP26 Conference a monitoring project was undertaken in Glasgow using small sensor technology including sensors for carbon dioxide. The results of this trial will be presented, with an explanation of how CO2


measurements


can contribute to source attribution and to the calculation of emissions indices.


This section will also include news of a potential game-changing project to host air quality monitoring networks onto existing cellular communications network infrastructure.


3. Joined-up thinking


In the past, there have been concerns that monitoring and modelling have been regarded as almost separate methods for the assessment of air pollution, but in this session, speakers will outline the case for greater integration. Monitoring should be used to calibrate and verify modelling predictions, and recent advances in low-cost sensors mean that greater spatial density of monitors can be deployed to enhance the reliability and granularity of modelling predictions.


In the general media and in the minds of the public, air quality and climate change are frequently represented as the same environmental problem. However, not all air pollutants have a greenhouse gas effect, and greenhouse gases are not usually toxic. Nevertheless, local air quality strategy is often separate to local climate change strategy. This might be because they may have separate budgets in both central government and local authorities, but this session will explain why both strategies should be combined. For local authorities, the greatest impacts on both air quality and climate change come from planning and development, so it is vital that these issues are addressed in the planning process.


4. Indoor Air Quality (IAQ)


Most people spend more time indoors than outdoors, so whilst it is important to tackle outdoor pollution, it is even more important to protect the quality of indoor air. When people meet indoors, carbon dioxide levels increase, and it is well known that this can cause drowsiness and harm the performance of offi ce workers and schoolchildren for example. However, the Covid pandemic further highlighted the importance of ventilation because the concentration of airborne infectious aerosols also increases in populated rooms with inadequate ventilation. Speakers will therefore describe a government pilot study in which CO2


and particulate sensors are being used to monitor ventilation in schools.


With energy costs soaring, the challenge will be to implement effective ventilation, whilst maintaining comfortable temperatures and minimising power consumption. The fi nal presentations will be given by abatement and ventilation specialists who will explain how these IAQ issues can be addressed, as cost-effectively as possible.


AQE – emissions monitoring and control


The regulations, standards and methods relating to the measurement of industrial emissions have been a key feature of all AQE events and the MCERTS events before that. AQE 2022 will continue to address this core issue with an additional focus on the role of monitoring in the fi ght against climate change.


On the fi rst day of AQE 2022, a speaker from the Environment Agency will set the scene with a presentation on relevant regulations, after which the Environmental Services Association (ESA) will outline a strategy for the recycling and waste sector to meet Net Zero. Both of these presentations will be given with particular reference to the monitoring requirements.


One of the speakers will also address the challenges of monitoring biogenic and fossil carbon emissions. Global initiatives are under way to reduce the use of fossil fuels, which has resulted in an increase in the use of fuels of biogenic origin as a replacement. Examples of biogenic carbon emissions include those from: the combustion of biogas from landfi ll, wastewater treatment, or manure management processes; the combustion of the biological fraction of municipal solid waste or biosolids; and emissions derived from the combustion of biological material, including forest-derived and agriculture-derived feedstocks.
