Air quality at COP27: novel insights and the challenges of urbanisation TALKING POINT


At COP27, hosted by Egypt in Sharm El-Sheikh, an expansive technical programme will explore the multifarious challenges posed by the climate crisis, bringing together expertise and state authority from all around the world. As always, the Conference will place an emphasis on the fi nancial, legal and regulatory structures necessary for the restriction of global warming to temperatures less than 2°C above pre-industrial levels in an attempt to build broad-based institutional momentum.


One of the focusses will be developments in air monitoring as part of the fi ght against climate change – and there are some highly novel perspectives. For instance, during COP27’s Science Day, which focusses on new measurement and conceptual approaches, there will be a session entitled ‘Dust Particles as Regulators of the Climate System’, which will stress the need for more accurate real-time observations of dust properties and for understanding dust triggering mechanisms, seasonal variabilities, and transport dynamics. The session proposes that such developments would assist in the mitigation of consequences from wind-blown dust, which impacts human health, weather, solar and wind energy systems, aviation, highway safety and urban development. As with all of the measures discussed at COP27, questions of funding, for both the private and public sectors, will be foregrounded.


Elsewhere, the dangers to air quality posed by urbanisation are discussed – in fact, it appears that much of COP27’s approach to the problem of climate change involves a reconsideration of urban development, perhaps stemming from the fact that Egypt remains a developing economy


at a tremendously complicated time to develop. It’s no surprise then to discover a session entitled ‘The Road from COP27 to the WUF12’ on the agenda, as the latter acronym denotes the 12th Session of the World Urban Forum. This event aims to synergise communities engaged in climate and urban action, to coordinate the implementation of multi-level strategies, and to raise the ambitions of Nationally Determined Contributions (formalised programmes for climate action by signatories to the Paris Agreement). It’s clear that COP27 is pushing for a broad-scale change to urban management, which will include lowering targets for ambient air as well as infrastructural changes.


With regards to the latter, other sessions will focus on rethinking urban mobility and the development of sustainable transport in the interest of actualising not only a carbon-neutral urbanism but one with public health at its core. In these sessions, innovative technologies that are low-carbon, aff ordable and non-polluting will be showcased, many of which have already been trialled in the Global South.


Analysis and quantifi cation of VOCs and sVOCs from plastic samples Bottled water


consumption has been growing up the last decades and is often perceived as pure and safe. Nevertheless, the Natural Resources Defense Council has shown that one third of the bottled water contained chemical pollutants such as chloroform or benzene in levels that exceed the regulatory limits. Therefore, there is a need for an industrial


monitoring system that can


analyse plastic samples before it is used for making bottles.


Chromatotec has designed a turnkey solution for the measurement of VOCs and sVOCs in plastic. The samples are heated at high temperature (typically between 200 and 300°C) to release the VOCs and sVOCs from the plastic. The emitted compounds are fi rst collected in a pre-concentrator and then injected in a chromatograph equipped with Flame Ionization Detector and a Mass Spectrometer. The results from both detectors are automatically processed with Vistachrom Software and provide automatically complete characterisation of the sample.


This analytical solution is perfectly suited for complete characterisation of plastics but also for analysis of VOCs and sVOCs emitted from any solid samples such as rubber or soil samples.

A perfect tool for direct continuous mercury determination


RA-915AM monitors are designed for continuous mercury measurements in ambient and indoor air, in hydrocarbon and process gases.


Monitors operation is based on differential Zeeman Atomic Absorption Spectrometry. Ideal for permanent installation at air monitoring stations, RA-915AM monitors allow ultra-sensitive determination of background Hg concentration. Optional multiplexer enables sampling from 2 to 16 points.


RA-915AM monitors can be used both for stationary measurement and for continuous surveys with automobile, ship or helicopter as carriers. Lumex Instruments’ monitors are optimised for long-term (months) measurements without the need for the frequent maintenance and recalibration. They operate in fully hands-off mode, including automatic zero drift and span drift correction, automatic recalculation to standard conditions, self-diagnostic, preventive maintenance functions, autorun function after power supply failure.


The use of the instruments allows cutting down operation costs as the analyser requires no argon cylinders for operation and no consumables. More information online: ilmt.co/PL/VEmm For More Info, email:
