Rubber pollution

Source: Wikipedia, the free encyclopedia.

Rubber pollution, similar to

soil pollution, and in waterways, lakes and the sea.[3]

Causes

See also: Non-exhaust emissions

Tire wear is a major source of rubber pollution.[4][5][6] A concern is that, unlike exhaust emissions, vehicle tire wear pollution is not regulated.[6] Some devices are nonetheless being developed in an effort to reduce the amount of particulates coming from the tire and otherwise ending up in the atmosphere.[7][8][9] Although not immediately visible to the naked eye, tire dust makes up a significant portion of road debris.[10][11]

Other sources can be artificial turf[12] and rubber O-rings and seals.[1]

Classification

Very fine rubber dust particles can depending on the classification be counted among

microplastic (because rubber is just another polymer) or separately (because its constituent monomers, the required additives, and the type of chemical bond mesh is slightly different). In a similar vein, rubber pollution is often implicitly mentioned when plastic pollution
is addressed.

6PPD-quinone, an antiozonant used in rubber tires, has been found to kill salmon when it accumulates into waterways from tire wear pollution.[13]

It is estimated that an average passenger vehicle tyre lasts for 40,000-50,000 km before it is worn out, with approximately 10-30% of its tread rubber emitted into the environment. ... A wide range of chemicals can be found in vehicle tyres, depending on required performance standards and the manufacturing company. It has been reported that a common-sized all season passenger commercial tyre contains approximately 30 kinds of synthetic rubber, 8 kinds of natural rubber, 8 kinds of carbon black, steel cord for belts, polyester and nylon fibre, steel bead wire and 40 different chemicals, waxes, oils, pigments, silica and clays.
