A series of retrofit low-NOx combustion demonstrations supported by EPRI and electric utility companies are intended to establish the technical and economic feasibility of this approach.","PeriodicalId":17188,"journal":{"name":"Journal of the Air Pollution Control Association","volume":"56 1","pages":"1294-1298"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80486915","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 raises the possibility that the 1-nitropyrene in the exhaust is coming from the crankcase oil, having formed or accumulated there. To evaluate this possibility, 1-nitropyrene exhaust emissions from a light-duty diesel vehicle were measured, along with the 1-nitropyrene content of its engine oil and of new oil. Results indicate that new oil did not contain 1-nitropyrene at the detection limit of 0.1 ppm. 1-nitropyrene did collect in oil to a concentration of 0.5 ppm at an oil usage and vehicle travel distance of 9000 km. Even though 1-nitropyrene was found in used diesel engine oil, this 1-nitropyrene does not appear to account for the 1-nitropyrene found in diesel exhaust emissions.","PeriodicalId":17188,"journal":{"name":"Journal of the Air Pollution Control Association","volume":"14 1","pages":"1255-1256"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84640326","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}

During the episode, TSP, RSP and SO2 concentrations were each in the range of 200-250 μg/m3, whereas during the baseline measurements, they were generally below 100 μg/m3. During the episode, pulmonary functions were significantly lower by 3-5 percent compared to the baseline measurements. The decline was still observed 16 days after the episode, but not 25 days after the episode. Differences in pulmonary function technician, pulmonary function test appliance and in the prevalence of colds between baseline and follow-up measurement were not able to explain the findings. These results suggest that an air pollution episode of a few days, with 24-hour average TSP, RSP and SO2 concentrations in the range of 200-250 μg/m3, was associated with a decrease in pulmonary function of primary school children.","PeriodicalId":17188,"journal":{"name":"Journal of the Air Pollution Control Association","volume":"36 11","pages":"1223-7"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00022470.1986.10466168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14911895","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}

However, difficulties in measuring dry deposition of reactive gases and fine particles make routine direct monitoring impractical. An alternate approach is to use the “concentration monitoring” method in which dry deposition flux is estimated as the product of measured concentration and estimated deposition velocity. A sampling system that performs over the period of 6 hours to 7 days, depending on atmospheric concentrations, has been developed. It consists of a Teflon cyclone to exclude particles larger than about 2 μm, selective solid adsorption media for reactive gases—some of which are sampled from a transition flow to avoid possible bias from particle evaporation, a particle filter, and a final gas adsorption filter to collect the remaining trace gas. The sampler Is the first reported application of transition flow mass transfer for the collection and quantitative measurement of trace atmospheric gases.

The data were fit to a simple three-term, steady state model describing the T and RH dependence of CH/sub 2/O concentration in a single compartment with a single CH/sub 2/O emitter. The model incorporates an Arrhenius T dependence and a nonlinear RH dependence of the CH/sub 2/O vapor concentration within the solid CH/sub 2/O emitter. The RH dependence is based on Freundlich's theory of the adsorption of water vapor on solid surfaces. The model is used to estimate potential seasonal variation in CH/sub 2/O concentrations under specified experimental conditions inside the research houses. The modeled results indicate six- to ninefold variation between 18/sup 0/C, 20% RH and 32/sup 0/C, 80% RH, simulating potential winter/summer conditions with minimal indoor climate control. In comparison, indoor conditions ranging from 20/sup 0/C, 30% RH to 26/sup 0/C, 60% RH yielded approximate two- to fourfold fluctuations in CH/sub 2/O concentration.

This paper provides cost information for initiating and operating a HWF program, and outlines the steps required to perform a thorough financial analysis. Falling fuel prices lessen the appeal of HWF programs, and unless the facility is paid to accept the HWF, only very large users (more than 80 × 109 Btu/yr) of energy can consider them.
