The author wishes to correct the errors. Abstract The present work investigated the effect of common gaseous pollutants on silver artifacts. The study was carried out on coupons made of a silver alloy (91 silver and 9% copper) with chemical composition similar to ancient Egyptian silver artifacts. These coupons were exposed to gaseous pollutants such as sulfur dioxide, nitrogen dioxide, carbon dioxide, hydrogen sulfide and chlorine, each gas separately. The exposure period was four weeks inside a climate chamber with 10 PPM concentration of each gas. After each test, examinations by SEM and PM were used to evaluate the effect of each gas and observe the formed tarnish layers. The results revealed that all gases reacted with the surface except carbon dioxide. The formed tarnish layers varied in coverage and density rate, and the heaviest layer was of H 2 S coupons. The tested coupons were analyzed by XRD and the results revealed Ag 2 S, AgCl, Ag 2 SO 4 , Ag(NO 3 ) 3 (NO) 3 , AgO and Ag 2 O as corrosion products.","PeriodicalId":93802,"journal":{"name":"Open journal of air pollution","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70572225","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}

Human activities release a large number of \u0000pollutants into the atmosphere which has a \u0000direct impact on plant health and leads to \u0000ecosystem degradation. The objective of this study is to contribute to a better \u0000evaluation of the impact of the air quality of the city of Togo on biological \u0000resources. The determination of pollutants was done on samples of plant species \u0000with a strong link with the source of pollution. The determination of Sulfur dioxide \u0000(SO2) was done by the ripper method. The determination of carbon and \u0000estimation of CO2 and CO by the colorimetric method. The \u0000determination of nitrogen was done by the \u0000Kjeldhal method. The results showed that at the industrial level the amount of CO2 in Alternanthera repens is high with a value of 53.3911 mg/ml. \u0000On the other hand, the quantity of CO in Senna occidentalis is 44.3619 mg/ml. In Pithecellobium dulce, the \u0000quantity of SO2 and NO2 are evaluated respectively to 0.1588 \u0000mg/ml and 0.3696 mg/ml. Regarding to the dumps, the quantity of CO2 in Newbouldia laevis is very high with a value of 65.8508 mg/ml. On the other hand the amount \u0000of CO in Senna occidentalis is \u000051.6106 mg/ml. The quantity of SO2 in Newbouldia laevis is 0.2101 mg/ml and NO2 in Ocimum canum is 0.2744 mg/ml. At the level of roads, the quantities of CO2 and CO in Eragrostis tenella are very high with values respectively equal to \u000074.4092 mg/ml and 62.2654 mg/ml. On the other hand, the \u0000amount of NO2 in Amaranthus sp is 0.2304 mg/ml and that of SO2 in Eragrostis Tenella is 0.1691 mg/ml. The use of a plant bioindicator sensitive to \u0000pollutants, allowed concluding that the air of the city of Lome is polluted. \u0000The concentration of carbon dioxide and \u0000carbon monoxide is much more evident in return when the health \u0000of plant species is threatened.","PeriodicalId":93802,"journal":{"name":"Open journal of air pollution","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43188731","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}

Air quality monitoring at CGQA deals with \u0000mainly six pollutants: carbon monoxide (CO), nitrogen oxides (NOx) \u0000(with nitrogen dioxide (NO2) and nitrogen monoxide (NO)), sulfur dioxide (SO2), \u0000ground-level ozone (O3), Benzene-Toluene-Xylenes (BTX), and \u0000particulate matters (PM) with diameters less than 10 μm (PM10) and \u00002.5 μm (PM2.5).

Several studies showed that Traffic-related air pollution (TRAP) \u0000is one of the main sources of urban air pollution and has serious consequences on \u0000respiratory health. As no systematic review focused on the traffic-related air pollution \u0000and respiratory health in the target population of individuals working in a shop \u0000or in an office or individuals living along the trunk road, the authors conducted \u0000the current study to try to fill this gap. Methods: A systematic review search \u0000was conducted using MEDLINE (PubMed), Scientific Research Publishing: SCIRP, Web \u0000of Science, Google scholar. Studies were included if they meet the following selection \u0000criteria: 1) focus \u0000on population working or living along a major/trunk road; 2) studies had reported clearly at least on the exposure \u0000variables related to TRAP; 3) the association between TRAP \u0000and development of respiratory symptoms or respiratory diseases was established. Results: 13 articles were selected on the 192 articles that were retrieved \u0000in the initial research. Exposure to traffic-related air pollution was determined \u0000by using distance to road, traffic intensity and pollutants measured. The main respiratory \u0000health problems found were cough, wheeze, asthma and bronchitis. No article discussed \u0000about roundabouts in characterizing exposure to traffic-related air pollution. Conclusion: Distance to road, traffic density and pollutants measured are the usual methods \u0000to characterize the exposure to traffic-related air pollution and its consequences \u0000on respiratory health. Regarding the context of area occupations in African cities, \u0000it is necessary to focus on population around roundabouts and see if they are not \u0000more exposed to TRAP.","PeriodicalId":93802,"journal":{"name":"Open journal of air pollution","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47874027","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}
