Wearable particulate and noise measurement instrument for peace of mind in the workplace
Pambry Instruments has further developed its range of wearable environmental monitoring equipment with a new particulate measurement device. The PED 1780 is small and light enough to be attached to your workwear to monitor the user-experienced noise level/dose and particulates present during the working day.
The instrument is calibrated and conforms to international health and safety standards and can be confi gured to use custom levels for specifi c requirements. The PED 1780 measures particulate matter (PM1.0 CO2
to PM10.0 ), noise level, noise dose, , CO, VOCs and ambient temperature/humidity
with a range of optional sensors. The data can be downloaded to a PC, or optional Cloud data analytics, for use in health and safety reporting and record retention, and for early warning of trending issues that may harm your personnel. This device also features Bluetooth connectivity to its mobile app and a klick-fast connector that can be used with a variety of attachments.
Users have the option of a visual or vibrating alarm to warn them of potential hazards. A powerful battery enables multi-day use, with up to 160 hours of usage, or 4 working weeks, depending
on sampling time; this can be charged using a USB C or wireless docking station. This is the latest of Pambry Instruments’ products in their highly reputable range of noise level/dose monitoring, noise alert, and CO2
/NO2 /O3 /VOC alert products.

DustCanary recognise the importance of high-quality dust measurement, particularly where the health and safety of workers is at stake. Airborne dust particles in the workplace pose signifi cant risks to human health, and monitoring their levels is key to helping prevent respiratory issues, allergies, and occupational diseases.
With the introduction of real-time personal dust monitoring to support control measures, the DustCanary Trend 420 provides visibility to changes in dust levels and dust hotspots, evidence of what is happening between periodic air sampling and can empower workers to help manage risk around their dust exposure.
At the heart of the device is a robust, high-quality sensor with 2l/min sampling from the front of the device for representative dust measurement. Compact, lightweight and with no sampling tubes or waist worn pumps as catch hazards, the DustCanary Trend 420 enables convenient, continuous use without interrupting productivity and work patterns. Instant visual and audible alarms alert when workers are exposed to increased respirable dust including respirable crystalline silica (RCS).
Used in conjunction with the DustCanary App, dust exposure profi les are captured and reported securely and conveniently. The data provides valuable insights to help diagnose the source of dust hotspots and monitor the effectiveness of mitigation actions and dust control measures to help reduce workers’ exposure to respirable dust.

Setting a new trend in personal dust monitoring
Chris Whitty: Tyres will soon pose a greater threat than exhausts TALKING POINT
Chief Medical Adviser to the UK government, Sir Chris Whitty, has recently drawn attention to a subtle yet critical source of pollution: car tyres. In his address to the Environmental Audit Committee in early July, Whitty emphasized the urgency of addressing tyre pollution, which, he argues, could potentially worsen in a future dominated by electric vehicles.
Despite being cleaner in terms of emissions, the shift towards electric vehicles does not completely alleviate pollution-related problems. This paradigm shift promises a marked reduction in pollutants such as nitrogen oxides from exhausts, however, it simultaneously highlights an often- overlooked source of environmental pollution: particulates from tyre and brake wear. According to a report by Imperial College London, toxic chemicals are released from tyre wear particles. This includes harmful substances like polyaromatic hydrocarbons, benzothiazoles, zinc, and lead, which either hang in the air or seep into nearby soil and bodies of water. Whitty warns that the heavier weights of electric vehicles might slightly increase tyre-related particle emissions, a concern that requires immediate attention.
There is a growing body of research suggesting that tiny particles produced by tyre wear, together with those from road surfaces and markings, pose a signifi cant health risk, now surpassing the hazards of exhaust emissions. These particulates can be deeply inhaled into the lungs and even infi ltrate the food chain. According to Jonathan Grigg,
a professor of paediatric respiratory and environmental medicine at Queen Mary University of London, further research is needed to understand the health eff ects of these non-combustion particles. Moreover, particles from tyre and brake wear, road abrasions, and their paint markings contributed to about 76% of all small particle pollution from road transport in 2021, as per a UK government data. This fi gure is remarkably higher than the mere 15% from car exhausts, underscoring the urgency of the tyre pollution issue. Experts and policymakers are calling for further research on tyre wear and new solutions to this pressing problem.
This issue has taken on renewed importance in the light of recent tests showing that modern cars generate nearly 2000 times more particle pollution from tyre wear than exhaust emissions. Nick Molden from Emissions Analytics warns that tyre pollution could swiftly become a major regulatory issue, given that tyre particles contain a wide range of toxic organic compounds, including carcinogens. The tests revealed that, with each kilometre driven, tyres produce more than a trillion ultrafi ne particles. These particles, which measure less than 23 nanometres, pose a unique health risk due to their ability to infi ltrate organs through the bloodstream.
Meanwhile, eff orts to reduce tyre emissions are gaining traction. Experimental trials of new tyre designs sponsored by Transport for London found them to emit 35% fewer pollutants. Similarly, the EU is working on legislation to
regulate tyre emissions, with new standards expected to be in place by 2025. Regulatory tools and surveillance measures for tyre wear and chemical content are currently lacking. Given the substantial variation in wear rate and toxic chemical content among diff erent tyre brands, Molden suggests that even low-cost changes could signifi cantly reduce their environmental impact.
The call for urgent action on tyre pollution is echoed by others in the fi eld. The Department of Environment, Food and Rural Aff airs stated that they are “conducting research and supporting the development of international legislation to better understand the scale and impacts of non-exhaust emissions, including automobile tyre and brake wear.”
