“…The above finding is consistent with the results of Nagafuchi et al (2009), who reported that most of the SCPs in a mountain lake in Japan originated from Japanese industrial activity. Although Rose et al (2004) reported that SCPs are largely deposited within 70-100 km of their source, Bindler et al (2001) discovered SCPs derived from Europe in lake sediments within Greenland, indicating the long-distance transportation (several thousand kilometers) of SCPs.…”

“…Although both SCPs and IASs are largely deposited within 70-100 km of their sources (e.g., Boyle et al 1999;Rose et al 2002Rose et al , 2004Larsen 2003), they are able to travel thousands of kilometers in air streams and their presence has been recorded in lake sediments at remote locations such as Greenland, Antarctica, and the Tibetan Plateau (Nagafuchi et al 2009 and references therein). Furthermore, the generally smaller size range of IASs (0.05-10 lm) has resulted in their identification in the midocean air samples (Parkin et al 1970), deep-sea marine sediments (Fredriksson and Martin 1963), high-latitude ice deposits in Greenland (Hodge et al 1963;Bindler et al 2001) and Antarctica (Hodge et al 1967), and in rime ice and lake sediment in alpine areas (Nagafuchi et al 1995(Nagafuchi et al , 2009).…”

SCPs are generally larger than IASs, with particle sizes of [10 lm being dominant (Rose et al 2002;Larsen 2003); consequently, their transportation distance is less than that of IASs.…”

The spatial and temporal distributions of spheroidal carbonaceous particles from sediment core samples from industrial cities in Japan and China

et al. 2011

Spheroidal carbonaceous particles (SCPs) are produced by the high-temperature combustion of fossil fuels and emitted in to the atmosphere. The distribution and concentration of SCPs in sediments have been used as a proxy for the distribution of pollutants emitted to the atmosphere. However, the effect on the distribution of SCPs due to industrial activity at nearby industrial cities is yet to be quantified. To clarify the origin of SCPs of *20 lm in size that are preserved in sediments, we evaluated the abundance, surface morphology, and chemical composition of SCPs in sediment core samples recovered from industrial cities in Japan (Tokyo, Osaka, and Nagasaki) and China (Beijing), with the cities being located at least *500 km away from each other. Vertical profiles of SCP concentration in sediment cores from the Japanese cities and Beijing are different, reflecting the contrasting industrial histories of the two countries. The SCPs from different cities show contrasting morphological and chemical characteristics, suggesting that *20 lm SCPs in sediments from the industrial cities could represent the local combustion history in detail, as the influx of local SCPs is dominant at such sites.

Guo et al (2004), Song et al (2008), and van Donkelaar et al (2010) reported on the general transport of industrial aerosols across northern China, and there are several reports specifically on the long-range transport of industrial lead aerosols in that area Cheng et al, 2005;2007a;Han et al, 2007b;Hao et al, 2007;Zhao et al, 2007b).…”

Lead contamination in China has been extensively documented by scientists in China and elsewhere over the past two decades, as summarized in this review of articles published in peer-reviewed scientific journals. Sources of that contamination include (a) deposits from previous emissions of leaded gasoline, which was finally eliminated in the past decade; (b) previous and continuing emissions from fossil fuel combustion, which are increasing markedly with the rapid industrialization of China; (c) previous and continuing emissions from other industrial activities, including mining, smelting and municipal waste incineration; and (d) previous and continuing additions of contaminated fertilizers, sewage, and untreated wastewater to agricultural fields. Lead concentrations of some Chinese agricultural produce are also elevated by acid rain and acidic fertilizers, which increase the solubility and bioavailability of both natural and contaminant lead in soil. In addition, some Chinese products are contaminated with lead during their production, processing, packaging, and transport. As a consequence of the long-range transport of industrial lead emissions from China and the global market for its products, the problem of lead pollution in China is a global problem.

Spheroidal carbonaceous particles (SCPs) are one of the types of fly ash particles produced by industrial fossil-fuel combustion. These SCPs are mainly composed of carbon, which enables them to be preserved in sediments for a long time; this preservation means that sedimentary SCPs have been used to study the distribution and history of environmental pollution. SCPs are used as a proxy for temporal and spatial atmospheric pollution, as a marker for sediment core dating, and as a proxy for the evaluation of transboundary pollution (i.e., the identification of the source of pollutants originating in one country but deposited in another country). The concentrations of sedimentary SCPs and their characteristics, such as morphology, size and chemical composition, provide useful information on past and present atmospheric pollution. This review provides a summary of the technique and its application, principally in Japan during the past decade.
