“…To illustrate the possible effect of not including the minor 204 Pb isotope in the ratios used to identify potential sources of Pb, I have plotted data from a compilation of Northern Hemisphere atmospheric lead data (Bollhöfer & Rosman, 2001) (Fig. 3a) and 206 Pb/ 208 Pb versus 206 Pb/ 207 Pb (Fig.…”

“…In East Asia, China is the primary producer and consumer of coal and metal ores (3)(4)(5). The Pb isotopic distinction between Asian and North American airborne particles was demonstrated by Bollhofer and Rosman in a survey of samples from the northern hemisphere (32). They emphasized the "very distinctive isotopic fingerprint" of Chinese airborne particles due to their higher 208 Pb (as Here we report Pb isotope ratios and elemental concentrations in airborne particles from a pair of sites selected to distinguish trans-Pacific vs. local urban sources: a coastal site near the San Francisco Bay Area (Mt.…”

During the last two decades, expanding industrial activity in east Asia has led to increased production of airborne pollutants that can be transported to North America. Previous efforts to detect this trans-Pacific pollution have relied upon remote sensing and remote sample locations.We tested whether Pb isotope ratios in airborne particles can be used to directly evaluate the Asian contribution to airborne particles of anthropogenic origin in western North America, using a time series of samples from a pair of sites upwind and downwind of the San Francisco Bay Area. Our results for airborne Pb at these sites indicate a median value of 29% Asian origin, based on mixing relations between distinct regional sample groups. This trans-Pacific Pb is present in small quantities but serves as a tracer for airborne particles within the growing Asian industrial plume.We then applied this analysis to archived samples from urban sites in central California. Taken together, our results suggest that the analysis of Pb isotopes can reveal the distribution of airborne particles affected by Asian industrial pollution at urban sites in northern California. Under suitable circumstances, this analysis can improve understanding of the global transport of pollution, independent of transport models.

Size-segregated (PM10) aerosol samples were collected at Ny-Ålesund (Svalbard Islands, Norwegian Arctic) from April to September 2012 and analysed for lead content and isotopic composition (207Pb/206Pb and 208Pb/206Pb), along with other chemical tracers, such as aluminium (crustal marker) and non-sea-salt sulphates (anthropogenic and marine biogenic marker). It was found that most of lead reaching Ny-Ålesund is anthropogenic, with a marked seasonality of both the concentration and isotopic signature. Particularly, average lead concentration in summer was significantly lower than in spring (p=0.003), whereas 208Pb/206Pb decreased from 2.107±0.002 to 2.090±0.005 (mean±95%-confidence level, p=6.0 10-6). A comparison of the measured isotopic ratios to literature data suggests that the atmospheric lead reaching the Arctic during spring can be mainly related to inputs from eastern Eurasia, whereas North America appeared to be the major source during the summer. Experimental results and sampling strategy also indicate that local inputs of crustal and anthropogenic lead play a minor role. The source-receptor relationship was confirmed by a back-trajectory cluster analysis of air-masses reaching the sampling sit
