Abstract
Data on the fate of tyre wear particles (TWPs) within aquatic environments is limited. This study quantified TWPs entering estuaries in stormwater drainage and atmospheric fallout, and once they have reached the marine environment, within surface waters and sediments. TWPs were found at concentrations of 0.4 mg/L, 2.55 mg/m2/d, 0.00063 mg/L, and 0.96 g/kg respectively. Samples were partitioned by size to examine the distribution of TWP mass. 80-90% of TWP mass entering marine systems (stormwater and atmospheric fallout) lay between 31-125 µm. Larger particles preferentially accumulated in sediments where ∼50 % of TWP mass was >250 μm, compared to surface waters where the size class 15-63 μm accounted for ∼80 %. This study provides novel data on the sizes and concentrations of TWP pollution in coastal environments. Such data are of importance in determining biological exposures. Notably, the presence of TWPs in surface waters demonstrates their potential for transport over longer distances.
