Abstract

Spheroidal carbonaceous particles (SCPs) are carbonaceous fly ash particles produced solely from industrial fossil fuel combustion. SCPs in sediments can be an indicator of past industrialization. We examined the sedimentary SCP record in Beppu Bay, southern Japan, and compared this record to historical trends of industrial activity and monitoring data for atmospheric pollutions in the region. Beppu Bay has varved sediments in the absence of bioturbation, providing an ideal situation for SCP study. Our results show that the temporal variation of SCP deposition is consistent with the trends of industrial activity and the temporal variation of status of atmospheric pollution. We conclude that undisturbed sediments such as Beppu Bay sediments have SCP records that adequately represent historical trends of industrial activity and atmospheric pollution in detail. These findings support that SCPs are a potential marker for the Anthropocene, characterized by industrialization.

日本南部别府湾沉积球形碳质颗粒(SCPs)记录与工业活动和大气污染历史趋势的比较:SCPs作为人类世工业化标志的进一步证据

球形碳质颗粒(scp)是仅由工业化石燃料燃烧产生的含碳粉煤灰颗粒。沉积物中的scp可以作为过去工业化的一个指标。我们研究了日本南部别府湾的沉积SCP记录，并将该记录与该地区工业活动的历史趋势和大气污染监测数据进行了比较。别府湾的沉积物在没有生物扰动的情况下发生变异，为SCP研究提供了理想的环境。结果表明，SCP沉积的时间变化与工业活动趋势和大气污染状况的时间变化相一致。我们认为，别府湾等未受干扰的沉积物具有SCP记录，可以充分反映工业活动和大气污染的历史趋势。这些发现支持scp是以工业化为特征的人类世的潜在标志。
