The data collected in this study, conducted on a 550-m mountain near the common border of New Jersey, New York, and Pennsylvania, show that daily maximum ozone concentrations and mid-day concentrations are similar at different altitudes but the ozone dosages increase with height. The lower the site, the more time the site is below the nocturnal inversion layer where the ozone is rapidly depleted. A site located at 500 m received an average ozone dose 32 percent greater than at the 300-m level and 72 percent greater than at the 140-m level.","PeriodicalId":17188,"journal":{"name":"Journal of the Air Pollution Control Association","volume":" 80","pages":"45-48"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91415512","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}

The ensuing transient condition, caused by the rapid devolatilization of waste materials, can momentarily deplete or displace local levels of excess oxygen in the kiln, resulting in heavy transient loadings of unburned gaseous and particulate hydrocarbons (here denoted as \"puffs\") leaving the kUn. This system upset must then be handled by an afterburner and subsequent air pollution control devices downstream. Such an overcharging or transient condition may even result in unacceptably low destruction of principal organic hazardous constituents (POHC) and the formation of products of incomplete combustion (PIC). A 73-kW (250,000-Btu/h) rotary kiln simulator was designed and constructed to provide engineering insight into the chemical and physical parameters associated with failure mode conditions.

Sulfate in soils may occur as water-soluble salts, adsorbed by soil colloids, or as insoluble forms. Considerable seasonal fluctuations in the concentration of soluble SO4 2− in surface soils occur as a result of interaction of seasonal conditions on the mineralization of organic S, leaching, and uptake by plants. Soils vary widely in their capacity to adsorb SO4 2− . Sulfate adsorption is readily reversible and the amount of SO4 2− adsorbed is concentration and temperature dependent. The capacity of soil to adsorb SO4 2− depends upon clay content, nature of clay minerals, pH, associated cation, and the amount of hydrous Al and Fe oxides. The mechanisms of SO4 2− retention by soils involve coordination with hydrous oxides, exchange on edges of silicate clays, incorporation in mineral structures, and molecular adsorption. For acid soils, SO4 2...","PeriodicalId":17188,"journal":{"name":"Journal of the Air Pollution Control Association","volume":"11 1","pages":"34-38"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89658574","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}

The program involved periodic accuracy audits and a review of available calibration drift data for selected CEMS. Accuracy audit results show that both SO2 and NOx CEMS are capable of providing accurate data on a long-term basis. However, frequent audits are necessary in order to verify the performance of an individual CEMS. The results of the calibration drift data evaluation show that despite infrequent occurrences of excessive drift, CEMS operated with a significant bias for extended time periods simply because corrective action was not taken in a timely manner.","PeriodicalId":17188,"journal":{"name":"Journal of the Air Pollution Control Association","volume":"82 1","pages":"27-33"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74855194","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}

It is directed mainly to incinerator operators, those who may conduct the actual sampling and analysis and those who must interpret trial burn results, but it will also be useful for regulatory personnel and others who need to understand trial burns. Potential trouble spots that have been encountered are: (1) trial burns frequently take more time and effort than an operator anticipates and (2) failure to meet the trial burn requirements.

The major advantages of this technique are that no other measurement methods can be used to determine the generated organic concentrations in lieu of Method 25; and that the cartridge can easily be taken to the field for evaluation. The organic compounds generated in test runs are collected and analyzed using the Method 25 procedure. The generation of organics is quantitative and recoveries were found to be 100 ± 10%.
