Arthur T Knackerbracket has found the following story:

A major UK government-funded research study suggests particles released from vehicle tyres could be a significant and previously largely unrecorded source of microplastics in the marine environment.

The study is one of the first worldwide to identify tyre particles as a major and additional source of microplastics. Scientists have previously discovered microplastics, originating from microbeads in cosmetics and the degradation of larger items such as carrier bags and plastic bottles, in marine environments globally—from the deep seas to the Arctic.

Following the government's ban on rinse off microbeads, which is one of the toughest in the world, the Defra-funded study [Defra - Dept for the Environment, Food, and Rural Affairs] led by the University of Plymouth now reveals vital new information that will improve our scientific understanding of how tiny particles from tyres, synthetic fibres from clothing and maritime gear also enter the ocean.

[...] The study shows the tyre particles can be transported directly to the ocean through the atmosphere, or carried by rainwater into rivers and sewers, where they can pass through the water treatment process. Researchers estimate this could place around 100million m² of the UK's river network—and more than 50million m² of estuarine and coastal waters—at risk of contamination by tyre particles.

Its findings also highlight some of the optimal places for intervention, for example, that fitting filters to washing machines could be less effective than changing fabric designs to reduce fibre loss, with another study at the University having recently shown that normal wear and tear when wearing clothes is just as significant a source of microplastic pollution as release from laundering.

[...] "What this study also does is provide further evidence of the complex problems posed by microplastic pollution. We have looked at three pathways and shown that all of them are substantive pathways to the environment. As we work to understand their potential distribution and impacts it is important to also work together with industry and policy makers to identify potential solutions which may include changes in behaviour, changes in product design and waste management."

    Dioxins can be used to efficiently bond lead to rubber microparticles. The cyanide produced can be absorbed by bubbling it through mercury until it's saturated, and then that can be disposed of in the nearest body of natural water, or the drain, depending on which is closer.
