作为轮胎磨损碎片和道路灰尘的指标，1989 年和 1993/94 年从东京市区收集的环境样本中检测到了 2-(4-吗啉基)-苯并噻唑 (24MoBT)。 24MoBT 存在于轮胎胎面橡胶、道路灰尘、径流颗粒、河水颗粒、河流沉积物和气溶胶中，浓度差异很大（∼ng g-1 至∼μg g-1）。轮胎胎面中 24MoBT 浓度与环境样品中 24MoBT 浓度的比较表明，轮胎碎片是环境颗粒物的重要组成部分。轮胎碎片对径流的贡献在暴风雨的早期和中期阶段最大。对 1993/1994 年收集的道路灰尘样本和河流样本中 24MoBT 浓度的比较表明，道路灰尘可能包含多达 28-65% 的暴雨河流悬浮颗粒和 5.5-41% 的河流沉积物。
As an indicator of tire wear debris and road dust, 2-(4-morpholinyl)-benzothiazole (24MoBT) was determined in environmental samples collected from urban Tokyo in 1989 and 1993/94. 24MoBT existed in tire tread rubber, road dust, runoff particles, river water particles, river sediment and aerosols in the widely varying concentrations (∼ng g-1to ∼µg g-1). Comparison of 24MoBT concentrations in tire tread with those in environmental samples showed that tire debris were a significant component of ambient particulate matter. The contribution of tire debris to runoff was greatest during the early and middle stages of storms. Comparison of 24MoBT concentrations in road dust samples and river samples collected in 1993/94 showed that road dust may comprise as much as 28-65% of suspended river particles during storm-flow and 5.5-41% of river sediments.
