Days with positive anomalies are frequent during winter/spring and early autumn, however, the autumn anomalies rarely represent pollution episodes. The meteorological analysis selects quasi-stationary, extratropical flow systems on the planetary scale, creating extended meridional exchange of air. Two indices are applied to the 500 hPa flow; a meridional index created by wave numbers 1, 2, 3 and 4, and a zonal index. The agreement between the values of the indices and Arctic ground level air pollution, on the annual as well as the episodic time scale, strongly suggests that the occurrence of quasi-stationary, atmospheric flow systems on the planetary scale is the major cause of long range transport of polluted air to the Arctic.</p></div>","PeriodicalId":100138,"journal":{"name":"Atmospheric Environment (1967)","volume":"23 11","pages":"Pages 2451-2462"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0004-6981(89)90256-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52834767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weekly samples of atmospheric aerosols were collected at three locations in the Canadian Arctic from mid-1983 to mid-1984. They were analyzed for elemental composition and stable lead isotope ratios (Pb <span><math><mtext>206</mtext><mtext>207</mtext></math></span>). High crustal enrichment factors confirmed that the majority of samples contained lead of anthropogenic origin. Pb <span><math><mtext>206</mtext><mtext>207</mtext></math></span> ratios were very uniform over time and between sites, suggesting a common origin of lead pollution in the Canadian Arctic. The mean isotope ratios at the Alert and Mould Bay stations were 1.160±0.010 and 1.161±0.006, respectively (samples from a third site at Igloolik were evidently contaminated by local sources). A small number of samples from Spitsbergen, taken during flow predominantly out of the northern U.S.S.R., were found to have a similar mean Pb <span><math><mtext>206</mtext><mtext>207</mtext></math></span> ratio of 1.154 ±0.006. From published lead isotope analyses of Soviet lead-bearing ores, we would expect a mean isotope ratio in industrial and vehicular emissions in the U.S.S.R. of around 1.158. Contributions to Arctic lead pollution from the U.S. and western Canadian sources can probably be ruled out, as they have significantly higher Pb <span><math><mtext>206</mtext><mtext>207</mtext></math></span> ratios. Similarly, emissions from northern Canadian and Kola Peninsula smelters can be disregarded, as they appear to have low isotope ratios. Eastern Canadian automotive lead aerosol contained only marginally lower Pb <span><math><mtext>206</mtext><mtext>207</mtext></math></span>ratios than in the Arctic, but meteorological studies argue against this region being a major source area for Arctic pollution. Scant European data suggest that European Pb emissions generally have lower isotope ratios than the Arctic samples. However, more data in Eurasia are needed before apportionments of Arctic Pb between sources within the region can be made.</p></div>","PeriodicalId":100138,"journal":{"name":"Atmospheric Environment (1967)","volume":"23 11","pages":"Pages 2513-2519"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0004-6981(89)90263-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52834850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These seven statistically significant modes of variability, which together accounted for 74.2% of the total variance, corresponded well with major SO_x emission patterns. Examination of the time series associated with each subregion revealed a general seasonality in which periods of high concentrations are more likely during the summer, while periods of low concentration are more likely during the winter. This seasonal cycle, however, was more prevalent in those subregions which contained few major emissions, and was less prevalent and often obscured by perturbations in those subregions which contained major emissions.</p></div>","PeriodicalId":100138,"journal":{"name":"Atmospheric Environment (1967)","volume":"23 12","pages":"Pages 2739-2750"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0004-6981(89)90554-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52836551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
