Volatilization (as indicated by PCBs trapped on polyurethane foam filters) resulted in a transport of 0·2–1·0 μg PCBs a week to air. Less chlorinated PCBs, i.e. tetrachlorobiphenyls, were transported to the air to a greater extent than more chlorine-substituted PCBs.Transport of PCBs by jet drops from bursting bubbles (as indicated by the amount of PCBs found on jet drop impactors) was of the same magnitude as volatilization, but the proportion of PCB compounds trapped by the impactor plates was identical with that of sediment and water. The process seems mainly to transfer PCBs containing bulk water and particles to the air.The results suggest that the contaminated sediment of lakes and watercourses may act as a source of PCBs to the atmosphere.</div>","PeriodicalId":100484,"journal":{"name":"Environmental Pollution Series B, Chemical and Physical","volume":"9 2","pages":"Pages 81-94"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-148X(85)90025-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86435378","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}

A λ MnO2 sample had an adsorption capacity of 15 mmol kg−1. Uptake was not influenced by pH over the range 5 to 11, but decreased in the 5 to 3 region due to protonation of sites. The amount adsorbed was reduced in the presence of chloride ions, with the extent, and pH of minimum uptake, being a function of Cl− level. As HgCl2 and Hg(OH)2 are the dominant solution species, and as protons were not released in the adsorption process, it is proposed that the adsorption mechanism involves migration of the Hg(II) species into the internal structure of the Mn(IV) oxide, where they either undergo ligand exchange with surface hydroxyl groups or are transformed into a solid hydroxy phase. The presence of sulphate ions further lowered Hg uptake. Extraction studies showed that adsorbed Hg could be totally released by EDTA, DTPA or 0·5m HCl. Decreasing quantities were displacedby 1m HNO3, Na4P2O7, Na3cit. Equilibration with 0·5m NaCl extracted about half, while 1m NH4NO3 or CH3COONH4 recovered < 5%.

The work presented here is an assessment of the feasibility of using environmental data to develop a plume dispersion model for the prediction of airborne TVP concentrations in the vicinity of an activated sludge sewage treatment plant. The monitoring data used were collected during an epidemiology study of the health of residents in the vicinity of an activated sludge sewage treatment plant located in a suburb of Chicago. Two types of modelling approaches were explored: dispersion modelling such as the Gaussian plume dispersion model and statistical modelling. The results of the statistical model have been reported elsewhere. The Gaussian modelling approach was limited because emission rates and rate of microbial die-off could not be measured, and techniques for their estimation proved inadequate. The die-off rate is normally expressed as a negative rate of change, but only positive coefficients were found. Although microbial growth in air is possible under certain conditions, it is thought that high background TVP concentrations due to many undefined sources of TVP in the study area were chiefly responsible for the positive coefficients. Until a better method is found for estimating the ambient total viable decay rate and defining background concentrations, the Gaussian plume dispersion modelling technique does not appear to provide a more useful approach for estimating TVP concentrations downwind from an activated sludge sewage treatment plant than does statistical modelling. Rather, the modelling process served to identify deficiencies in the application of the Gaussian plume model to ground level source aerobiological emissions when there is a significant background concentration.</div>","PeriodicalId":100484,"journal":{"name":"Environmental Pollution Series B, Chemical and Physical","volume":"9 3","pages":"Pages 215-235"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-148X(85)90034-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83084119","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}

This proposed relationship between soil and dust trace metal composition was investigated in north Wales, in an area where lead mining has caused intensive and extensive heavy metal contamination of agricultural and garden soils, and in a control area. Paired garden and house dust samples were collected from the houses of random samples of 90 subjects and were analysed for Cd, Cu, Pb and Zn. Compared with soils from the control village the contaminated soils were enriched (ratios of geometric means) by factors of Cd = 6·7, Cu = 1·1, Pb = 14·1 and Zn = 3·8. The similar ratios for dust were Cd = 1·2, Cu = 1·1, Pb = 1·9 and Zn = 1·1. Correlation analysis suggested that soil contributes little Cd, Cu or Zn to dust but 27% of the variability in dust Pb could be explained by soil Pb and the gradient of the log-dust Pb/log-soil Pb regression was 0·3. Subsequent resampling in 11 houses demonstrated little change over two months in dust Cd, Cu or Zn concentrations. Pb levels did change and were poorly correlated in the two sample sets, which may be explained by differences in the amounts of contaminated soil carried into the house before the dust was sampled.</div>","PeriodicalId":100484,"journal":{"name":"Environmental Pollution Series B, Chemical and Physical","volume":"9 4","pages":"Pages 255-266"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-148X(85)90002-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78693606","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}
