| 中文摘要 | 溶解态黑碳(DBC)作为黑碳(BC)降解的中间产物,是海洋溶解有机碳碳库的重要组分,涉及全球海洋碳收支并进一步影响全球气候变化;是有色溶解有机质的重要组分,可改变水体光学环境从而对生态系统产生影响;也是一类良好的有机配体,在环境中易与金属离子形成络合物从而影响金属污染物的行为与毒性。鉴于其在气候变化、生态和环境等方面的重要影响,近年来研究者越来越关注DBC,并取得了一些基础性成果。目前,在DBC的定性认识上还存在一些模糊区域,所以DBC还没有一个明确的定义,DBC只是一个术语,特指一类由浓缩稠环母体和亲水性取代基(主要为羧基)组成的复杂有机物。在DBC的来源方面,已有证据证明BC降解能够产生D... |
| 英文摘要 | Dissolved black carbon ( DBC) is a series of intermediate products from black carbon ( BC) degradation．It is an important part of dissolved organic carbon pool which relates to oceanic carbon budget and thereby plays a key role in global climate change． DBC is probably the main component of chromophoric dissolved organic matter，which can absorb solar radiation and change the optical environment of water，and then influences the functions and structures of aquatic ecosystems． It is also an organic coordination center which can easily form complex with metal ions and then influences the fate and toxicity of metal pollutants． For these reasons，DBC has received more and more attentions in recent years and some basic knowledge on DBC is available for us． However，①There is still ambiguity in qualitative DBC so that DBC is a terminology more than a definition specially to describe a series of complicated compounds which consists of condensed aromatics as parent core and substituted with hydrophilic groups ( mainly carboxyl) ． ②BC degradation is not the only source of DBC，other sources are urgently needed to be confirmed． ③The quantification of DBC is a great challenge for the high polarity of DBC and the complex matrices，which are difficult to be separated with DBC． Using benzene polycarboxylic acids ( BPCA) as molecule markers is a prospective method for the measurement of DBC，but there are still some problems that needed to be solved． ④The data on concentrations of DBC are sparse and varied in a wide range，making it difficult to estimate the pool and cycle period of DBC． This article summarizes the research progress in molecular level identification，sources，migration and transformation，measurement methods，concentrations and spatial distributions of DBC． One of the key points is the present status and problems of BPCA method． Finally，some suggestions are provided for further study． |
