With the on-going roll-out of electric vehicles, tyres and their associated emissions are potentially becoming the biggest source of pollution from motor vehicles, but measuring them is hard. It is an important area as tyres have been identified as potentially the largest source of microplastics in the ocean, as a result of run-off into water courses. Emissions Analytics has been leading the development of real-world test methodologies, both for tyre wear rates, but also to profile the chemical composition and potential toxicological effects of the wear on humans and the wider environment. Initial work on potential regulation is underway at the United Nations.Tyre wear is more complex to measure than other emissions, including tailpipe, because tyres are part of an open system, where material abraded from tyre is 'sprayed' into the environment, where it mixes with other material - brake wear, road wear, resuspended dust and pollution from other sources. The challenge, therefore, is to be able to take a sample from on or near a vehicle and being able to estimate with good accuracy the tyre wear material contained in it, separately from the non-tyre components. Each of those pollution sources has a different chemical fingerprint, or contains unique tracers that can help separate them from each other. Without such separation, while we can measure the material lost from a tyre, we cannot fully understand in what form it is shed and where it goes.Emissions Analytics has an existing capability to measure the organic constituents of tyre wear using an in-house state-of-the art chemical analysis, using which it has developed a tyre fingerprinting database for the potentially harmful carbon-containing compounds in tyres. It has also developed a patent-pending system for physically sampling tyre wear material on a vehicle as it drives around in the real world. Therefore, many of the components required are in place to address the problem, but additional analytical expertise in both sampling optimisation and source apportionment data analysis is needed to achieve a high quality, market-ready offering.Therefore, by addressing this sampling and measurement challenge, there is the potential to unlock private sector value together with a public value in addressing current and pre-empting future environmental challenges. For Emissions Analytics, it would form an additional element to its growing suite of tyre analysis services.

随着电动汽车的不断推出，轮胎及其相关排放可能成为机动车最大的污染源，但测量它们是困难的。这是一个重要的领域，因为轮胎已被确定为海洋中微塑料的潜在最大来源，这是径流到水道中的结果。排放分析公司一直在领导开发真实世界的测试方法，不仅用于轮胎磨损率，还用于分析磨损对人类和更广泛环境的化学成分和潜在毒物影响。联合国正在进行潜在监管的初步工作。轮胎磨损的测量比包括尾气排放在内的其他排放更复杂，因为轮胎是开放系统的一部分，轮胎磨损的物质被喷洒到环境中，在环境中与其他材料混合-刹车磨损、道路磨损、再悬浮粉尘和来自其他来源的污染。因此，挑战是能够从车辆上或附近采集样本，并能够高精度地估计其中所含的轮胎磨损材料，而不是非轮胎部件。这些污染源中的每一个都有不同的化学指纹，或者含有独特的示踪剂，可以帮助将它们彼此分开。如果没有这样的分离，虽然我们可以测量轮胎损失的物质，但我们不能完全了解它以什么形式脱落以及它去了哪里。排放分析公司现有的能力使用内部最先进的化学分析来测量轮胎磨损的有机成分，该公司利用该分析开发了轮胎指纹数据库，以确定轮胎中潜在有害的含碳化合物。该公司还开发了一种正在申请专利的系统，用于对车辆在现实世界中行驶时轮胎磨损材料进行物理采样。因此，解决这一问题所需的许多组件已经到位，但还需要在采样优化和来源分配数据分析方面的额外分析专业知识，以实现高质量、随时可供市场使用的产品。因此，通过应对采样和测量挑战，有可能在应对当前和先发制人的未来环境挑战方面释放私营部门价值和公共价值。对于排放分析公司来说，它将成为其日益增长的轮胎分析服务套件的一个额外元素。
