鸟类可以作为空气污染的有效生物监测器，但很少有研究量化鸟类羽毛上的外部颗粒物积累。由于元素碳是颗粒物的一种组成部分，对空气质量和人体健康具有不利影响，因此对空气中元素碳（EC）进行生物监测具有重要意义。为了评估其有效性，用于EC监测，我们比较了EC积累在两个站点，不同的车辆交通量在城市环境中的达拉斯-沃斯堡大都市区，美国的鸟类羽毛。在两个城市的微环境中，1.5公里远的交通量不同-邻近州际公路和大学校园的公共汽车站，实验暴露于环境EC污染5天，从国内鸡发霉的飞羽。高速公路附近的羽毛平均积累的EC（307 ± 34 μg m-2 day-1）大约是公交车站附近羽毛（40 ± 9 μg m-2 day-1）的八倍。这些研究结果表明，EC的羽毛上的积累在短距离内城市地区和鸟类羽毛可能可用于生物监测空气中的EC。
Birds can serve as effective biomonitors of air pollution, yet few studies have quantified external particulate matter accumulation on bird feathers. Biomonitoring of airborne elemental carbon (EC) is of critical significance because EC is a component of particulate matter with adverse effects on air quality and human health. To assess their effectiveness for use in EC monitoring, we compared EC accumulation on bird feathers at two sites that differed in vehicular traffic volume in an urban environment within the Dallas-Fort Worth Metropolitan Area, USA. Moulted flight feathers from domestic chickens were experimentally exposed to ambient EC pollution for 5 days in two urban microenvironments 1.5 km distant from each other that differed in traffic volume––adjacent to an interstate highway and a university campus bus stop. Feathers near the highway accumulated approximately eight times more EC (307 ± 34 μg m−2day−1), on average, than feathers near the bus stop (40 ± 9 μg m−2day−1). These findings indicate that EC accumulation on feathers varies over short distances within urban areas and that bird feathers potentially can be used for biomonitoring airborne EC.
