The primary aim of this study was to understand the potential of the non-steady state dissolution of silicate minerals in treatment of acid and metalliferous drainage (AMD) resulting predominantly from pyrite oxidation. To this end, flow-through dissolution cell experiments were carried out using selected silicate minerals (biotite, chlorite, olivine and K-feldspar), all commonly found in AMD environments, under various pH and flow rate conditions, for comparison to pyrite dissolution carried out under the same conditions. Both acid generation rate (pyrite) and steady-state and non-steady state acid neutralisation rates (silicates) were calculated and compared. Results showed that the non-steady state acid neutralisation rates due to silicate dissolution were greater than the steady-state neutralisation rates and that all silicate minerals investigated in this study, except K-feldspar, can provide acid neutralisation rates to match the acid generation rate due to pyrite dissolution under certain conditions.","PeriodicalId":177098,"journal":{"name":"Journal of Environmental Science and Engineering Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134017304","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 early stages of biofilm formation near a naphthalene crystal that was deposited on a glass coverslip were assayed qualitatively by growing the biofilms in batch bioreactors using either a rich carbon medium or a medium which contained naphthalene as a lone carbon source. Our results demonstrated that the biofilm selectively grew immediately adjacent to the edge of the PAH crystal, leading to a biofilm that facilitated the PAH degradation. Moreover, because PAH compounds are often found in capillary spaces in the subsurface, quantitative capillary-experiments were executed to evaluate the ability of P. naphthalenovorans biofilms in the degradation of a capillary-bound PAH contaminant. These capillary-experiments demonstrated that a biofilm forms at the pore’s opening, and that, when compared to a diffusion process in a liquid medium, this biofilm substantially increased the rate at which the PAH is cleared from the pore. These results provide an enhanced understanding of the means of biofilm adhesion and development in a presence of the model PAH compound investigated. Moreover, the work presented here demonstrates approaches not used before for monitoring biofilm formation.

The highest elemental concentrations were found at industrial sites and generally a decreasing trend with distance was observed. For most of the crustal elements, contamination factors (CF, element concentration in polluted area/element concentration in background area) were low (< 2). For Bi, Cr, Pb, Sn, and Zn, the Iskenderun region was classified as seriously contaminated (8 < < 27), while for several elements, including Cd, Ag, Cr, As, Fe, Mn, Sn, Mo, Se, Pb, Ni, Sb and Zn the region was classified as moderately contaminated (3.5 < < 8). Sources of trace elements in Iskenderun industrial region were investigated using Principal Component Analysis (PCA). PCA have identified four factors as crustal-resuspended particulate matter, iron-steel plant emissions, marine aerosol, and accumulation of nutrient elements on plants. Spatial variations of anthropogenic-based trace elements supported the finding that iron-steel facilities are their major sources in the Iskenderun industrial region. Results of this study confirmed that tree components and litter can be used as passive samplers to explore the geographical distribution of atmospheric pollution.","PeriodicalId":177098,"journal":{"name":"Journal of Environmental Science and Engineering Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133730341","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 emissions were calculated by using emission factors for three vehicle types; the passenger boats, the ferries carrying on-road vehicles and passengers, and the ships used for freight transport. The data of vehicle types and numbers, engine specifications for each vehicle type, fuel consumptions, passenger numbers, freight amounts, etc. for maritime traffic in Izmir Bay were collected. Emissions of NOx, CO, VOC and PM were estimated using the data collected and the emission factors from EMEP/CORINAIR database. The emissions emitted by the vehicles used for public transport were estimated as 12 tons/year for particulate matter (PM), 112 tons/year for nitrogen oxides (NOx); 60 tons/year for carbon monoxide (CO) and 29 tons/year for volatile organic compounds (VOCs). The emissions emitted by the ships coming to Izmir Harbour for trading were estimated as 24 tons/year for PM, 314 tons/year for NOx, 65 tons/year for CO and 30 tons/year for VOCs. Total emission in the bay were found 36 tons/year for PM, 426 tons/year for NOx, 125 tons/year for CO and 59 tons/year for VOC. The maritime emissions of PM and NOx in the bay are about 58 and 70 times lower, respectively than road transport emissions in the city.

A study was therefore conducted to assess the quality of effluent discharged into a stream, water in the stream and in the soil in the surrounding fields. Both the effluent and the water at selected points in the stream were analyzed for some parameters in the dry and rainy seasons. In the soil, pH, phosphorus, organic matter, soil respiration, electrical conductivity and nitrogen were analyzed only in the dry season. The results showed that the effluent and the water at all points sampled were slightly acidic in both the dry season and wet season. The dissolved oxygen was low in dry season but was relatively high in rainy season. The electrical conductivity and total dissolved solids had high concentrations in both seasons. Phosphate was high in the effluent in both seasons. The water upstream had higher levels of dissolved oxygen than at all points down the stream in both seasons.
