摘要
黑碳(black carbon,BC)作为典型的颗粒污染物,具有复杂的组成,能够对空气质量、生态环境甚至人体健康产生深远的影响.深入探究BC的赋存、分布特征和迁移转化过程,对深刻理解其对气候变化、大气污染控制、健康效应的影响具有重要意义.BC来源于自然和人为活动,并可在水-气-固三相间跨介质传输,增加了其溯源解析研究的难度.BC的时空分布受诸多种因素影响,包括地理、气象和排放源等,其研究极具挑战性.本综述分析了 BC的源与汇,归纳了其在不同环境介质中赋存、时空分布特征及迁移转化,总结了其分布规律与关键影响因素,可为更好的理解"碳循环"及实施"双碳战略"提供基础理论支撑.
Abstract
Black Carbon(BC),a common particulate pollutant,has a complex composition that profoundly impacts air quality,the ecological environment,and even human health.Delving into its occurrence,distribution,and transformation processes is crucial for a deep understanding of its effects on climate change,air pollution control,and health implications.BC arises from both natural and anthropogenic sources and undergoes cross-media transmission among water,air,and soil phases,complicating its source tracing studies.Its spatiotemporal distribution is influenced by various factors,including geography,meteorology,and emission sources,making its study challenging.This review focused on the sources and sinks of BC,its presence,spatiotemporal distribution,and transformation in different environmental media,the distribution patterns and key influencing factors,which provided theoretical support for better understanding of the"carbon cycle"and the implementation of"dual carbon strategy".
