This document establishes a general framework and considerations for assessing the environmental fate of tyre tread chemical additives in cured polymer and tyre and road wear particles (TRWP) throughout a tyre lifecycle. This document is applicable to laboratory-generated TRWP from cured tread polymer of known composition.<\/p>\n
Testing strategies are described for assessing the environmental fate and transport of tyre chemicals in the following processes that can occur during the tyre lifecycle:<\/p>\n
transformation of chemical additives in tread during tyre curing;<\/p>\n<\/li>\n
transformation of chemical additives during TRWP generation (tyre use);<\/p>\n<\/li>\n
transformation of chemical additives during TRWP aging and weathering;<\/p>\n<\/li>\n
leaching of chemical additives and transformation products from TRWP to water;<\/p>\n<\/li>\n
availability of chemical additives and transformation products from TRWP in sediment ecosystems.<\/p>\n<\/li>\n<\/ol>\n
Mass concentrations and fractions of chemicals released or available from TRWP for the five lifecycle steps are used to estimate<\/p>\n
cumulative fraction of tread chemical(s) and transformation product(s) released to water, and<\/p>\n<\/li>\n
cumulative fraction tread chemical(s) and transformation products(s) environmentally available.<\/p>\n<\/li>\n<\/ol>\n
