Heavy metals are introduced to coastal and marine environments through a variety of sources and activities including sewage and industrial effluents where Black Sea is not different. However, metals behave differently in Black Sea as it an enclosed body. Coastal areas of Turkey face great challenges due to heavy metal contamination caused by rapid urbanization and industrialization. The aim of this study was to investigate the spatial and temporal distributions of total mercury (Hg) in seawater at the mid-Black Sea coast of Samsun, Turkey. The samples were collected from 13 monitoring stations, from the three distances in four seasons during the year 2013. The samples were analyzed for physicochemical parameters along with contamination and enrichment factors. The distribution of Hg is nearly random along the studied coast but obtained values ranges from 0.57 to 12.6 μg/L with an average of 5.24 μg/L were above permissible limits. It was observed that number of samples collected during wet seasons (winter and autumn) with Hg were higher. High enrichment factor 0.331 and contamination factor 25.2 was recorded. Hg present at sampling station M27 was due to point source, a possible ship activity indicated by enrichment factor. The sources responsible for water pollution with Hg are mainly municipal and industrial effluents, leaching, agricultural and pasturage runoff and oil spills. Furthermore, due to unique hydrography of Black Sea, risk of Hg accumulation is high. Interestingly, a direct relation between basicity and Hg concentration was observed. i.e. highest concentration was found on pH 8.33.","PeriodicalId":14606,"journal":{"name":"issue 2","volume":"280 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76790883","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}

Tirunelveli city generates municipal waste of nearly 15 MLD of domestic wastewater and 100 tons of solid waste in a day. The domestic wastewater is treated by waste stabilization pond. The solid waste is dumped in the open yard. These two disposal sites are located in the Ramayanpatti area and their boundaries are at a distance of 500m from each other. Ground water resources are extracted in use for agriculture in the area of Ramayanpatti. Around thirty, locations have been identified in the Ramayanpatti area for sampling, based on the contour and flow direction. The dominant chemical cation species in the majority of the groundwater samples are in the order of Na>Ca>Mg>K and anion species are in the order of HCO3>Cl>SO4>NO3. Gibbs plot shows that the region is dominated by evaporation and dilution phenomenon. Rhode’s plot shows that there is no reduction in the rate of infiltration of soil in the Ramayanpatti region. Dendrogram shows that the leachates infiltration is predominant in the winter season. The study shows that the groundwater quality, nearer and to the southeastern side of the disposal sites are most affected and contaminated by solid waste leachates. The inference with various irrigation plots show that the quality of groundwater in the southeastern region is doubtful for use in irrigation and the groundwater needs to be assessed in order to use in irrigation for agriculture.","PeriodicalId":14606,"journal":{"name":"issue 2","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86393254","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}

In this study, PM1 number concentration, traffic flow, temperature and relative humidity in both a residential underground garage and at the entrance/exit, wind velocity at the entrance/exit were measured between May and June 2012 in Harbin, China. Pearson and partial correlations were employed to quantify the relationship between PM1 number concentration, traffic flow, and the thermal environment. The results show that mean PM1 number concentration in the garage during the measurement was 21,905 particles cm−3, which was approximately 1.54 times higher than the outdoor environment. Mean traffic flow, with a value of 0.2 vehicles min−1, may be the most important factor impacting PM1 pollution levels in the garage. The effects of air temperature inside the garage and wind velocity at the entrance/exit on PM1 pollution may be stronger compared with other environmental parameters. An inverse relationship between air temperature and PM1 number concentration was observed and decrease in wind velocity at the entrance/exit resulted in increased PM1 number concentration. This study provides fundamental reference data for PM1 number concentration levels in a residential underground garage.","PeriodicalId":14606,"journal":{"name":"issue 2","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89526040","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 main objective of this research is to explain spiritual tourism and present elements of marketing mix for attracting spiritual tourists with inclusive attitude. The paper describes spiritual travellers with inclusivity going on journeys for spiritual enhancement and veneration for divine places of other faiths considered as holy sites. Methodology: A qualitative study constructed on face-to-face interviews with tourists qualified as spiritual travellers was managed in selected Australian and Pakistani locations. The discussion notes were screened through theme-based assessment searching for ideas and themes surfacing from interviews aligned with elements of the marketing strategy. Results: This study resulted in acknowledging people, pricing and products as vital elements of tourism marketing complementing the spiritual tourism marketing strategy design and implementation. Conclusions: This study concludes with an inclusive spiritual tourism model indicating people, pricing and products to be embraced by tourism providers to enhance their marketing outcomes. This paper accomplishes by offering the recommendation for Pakistan’s tourism administration to market holy and blessed places linked with different faiths following the branding theme of “spiritual tourism”. Future Direction: Tourism marketing mix based on people, pricing and products, could be analysed by a quantitative research testing inclusivity based behaviour of spiritual travellers. Originality: The unique and primary study handled the threat of disinclination of tourists expressing their personal religious opinions through private meetings and face-to-face discussions.","PeriodicalId":14606,"journal":{"name":"issue 2","volume":"108 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89709603","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}
