Benzene series (BTEX) pollutants which are generated by traffic can deposit (build-up) on urban road surfaces. When they are washed-off by stormwater runoff, BTEX are toxic to ecological and human health if the stormwater is reused. To understand the risk posed by BTEX, it is essential to have an in-depth investigation on BTEX build-up, one of the most important stormwater pollutant processes. This study analysed the relationship between BTEX build-up and BTEX build-up's influential factors. The outcomes confirmed an important role of climatic factors (particularly temperature) on influencing BTEX build-up. This has not been considered in previous stormwater studies although this has been widely focused in atmospheric pollution. BTEX build-up loads were generally higher and the variability was low in dry seasons with low temperature such as winter and spring. Additionally, the influence of temperature on BTEX build-up on urban road surfaces is more important in the case of larger particles (such as >75 μm) than smaller particles. The study also showed that petrol station areas have a potential to export stormwater runoff with high BTEX concentrations, compared to typical urban roads. This is particularly applicable in winter and spring. These outcomes can provide useful guidance to improving stormwater quality modelling approaches, especially relevant to estimation of BTEX concentrations in the stormwater.

表征城市道路上的苯系(BTEX)污染物积累过程:对温度重要性的暗示

交通产生的苯系(BTEX)污染物可能会在城市道路表面沉积(堆积)。当它们被雨水径流冲走时,如果再利用雨水,BTEX对生态和人类健康是有毒的。要了解BTEX带来的风险,有必要对BTEX的形成进行深入研究,BTEX的形成是最重要的雨水污染物过程之一。这项研究分析了BTEX积累与BTEX积累的影响因素之间的关系。结果证实了气候因素(尤其是温度)在影响BTEX积累方面的重要作用。尽管这已经广泛地集中在大气污染上,但以前的雨水研究并未考虑到这一点。在冬季和春季等低温干旱季节,BTEX的堆积负荷通常较高,而变异性较低。此外,在较大颗粒(例如> 75μm)的情况下,温度对城市道路表面BTEX堆积的影响比较小颗粒更为重要。该研究还表明,与典型的城市道路相比,加油站地区有可能出口BTEX浓度较高的雨水径流。这尤其适用于冬季和春季。这些结果可以为改进雨水质量建模方法提供有用的指导,尤其是与估计雨水中BTEX浓度有关。75微米)。该研究还表明,与典型的城市道路相比,加油站地区有可能出口BTEX浓度较高的雨水径流。这尤其适用于冬季和春季。这些结果可以为改进雨水质量建模方法提供有用的指导,尤其是与估计雨水中BTEX浓度有关。75微米)。该研究还表明,与典型的城市道路相比,加油站地区有可能出口BTEX浓度较高的雨水径流。这尤其适用于冬季和春季。这些结果可以为改进雨水质量建模方法提供有用的指导,尤其是与估计雨水中BTEX浓度有关。
