However, phosphorous from vehicular sources has been given little consideration as a possible roadside contaminant. This paper examines the potential contamination of surface water (via runoff to storm drains and discharge to waterbodies) and groundwater (via roadside soil infiltration) by the phosphorous deposited onto pavement and road shoulders in the city of Waterloo, Ontario, Canada. Total and soluble reactive phosphorous concentrations in roadside soil and runoff samples were determined for two study sites. Subsequently, the results were statistically analyzed. Following comparison to other sources of urban runoff, it was concluded that roadways are a significant source of phosphorous in urban runoff, with high potential to impact surface water. Conversely, results of this work indicate that vehicular-sourced phosphorous does not pose a significant threat to groundwater.","PeriodicalId":45615,"journal":{"name":"Cogent Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23311843.2020.1794702","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47051646","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 the current study, the heavy metal content of water and edible muscles of a piscivorous fish (Protopterus annectens) as well as bioaccumulation of the heavy metals in fish tissues were evaluated. Samples of water (n = 6) and fish (n = 6) were taken from Kirinda bridge and Ruliba station on Nyabarongo river and analyzed by UV spectroscopy and atomic absorption spectrometry, respectively. The heavy metal concentrations in water were: iron (0.63 ± 0.02 and 1.61 ± 0.03 mg/kg), manganese (0.53 ± 0.002 mg/kg at Ruliba station), chromium (0.06 ± 0.002 mg/kg at Kirinda bridge), cadmium (0.106 ± 0.002 mg/kg at Ruliba station) and lead (0.75 ± 0.02 and 0.051 ± 0.01 mg/kg).

Most of the heavy metal contents were above the recommended levels. Bioaccumulation factors recorded in Protopterus annectens ranged from 403.2 to 15,130 L/kg, implying that consumption of this fish could pose deleterious health risks.

The current decontamination option is soil washing with chemicals whose efficiency is limited owing to high cost of reagents. This prompted the need for an environmentally friendly approach to remediate the contaminated soil. Therefore, the potential of Ganoderma lucidum to remediate heavy metals from an abandoned battery slag was investigated in this study. The heavy metals absorbed fungi were immobilised in bricks. The battery slag contaminated and control soil samples were analysed for HM concentrations before and after incubation with G. lucidium for 1–3 months. The harvested rice straw and mycelia were processed and analysed for HMs concentrations. For immobilizing heavy metals absorbed in mycelia, 5 to 30 g of pulverized mycelia were homogenized with a virgin soil, extruded into moulds and fired in a tunnel kiln for making bricks. The leachability of HMs from the bricks was carried out using TLCP. The concentrations (mg/kg) of Pb(4490 ± 14), Zn(147 ± 11), Ni(27.7 ± 0.2), Cu(19.4 ± 0.1) and Cd(2.18 ± 0.06) in dumpsite soil were significantly higher than the corresponding concentrations in the control soil samples. The G. lucidum inoculated on contaminated soil accumulated 138, 29.8, 3.48, 3069 and 1.01 mg/kg of Pb, Zn, Ni, Cu and Cd, respectively. This reveals the strong affinity of G. lucidum for toxic metals. The Pb, Zn, Ni, Cu and Cd immobilised after leaching procedure ranged from 45.3 to 98.10%. Immobilisation of toxic metals hosted by G. lucidum in red bricks can reduce environmental contamination by metals.","PeriodicalId":45615,"journal":{"name":"Cogent Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23311843.2020.1847400","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46915789","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}

Although these woodlands contain less carbon than humid forests, they are important for having large coverage and thus potentially important for national REDD+ carbon accounting. These woodlands are highly susceptible to forest degradation due to anthropogenic activities. Degradation activities are difficult to assess through remote sensing techniques alone. Alternatively, they can be estimated by using proxy variables such as infrastructure and settlements. This study is focused on the assessment of spatial patterns of forest degradation in Miombo woodland in Southern Tanzania. Diameter of stumps was collected through inventory of circular plots of 15 m radius in 25 transects at 500 m, 2500 m and 3500 m distance from the forest border. Group discussions and interviews with key informants provided additional information about local degradation activities. The spatial relationship between forest degradation and the proxy variables: major roads, settlements and forest edge were assessed with logistic and mixed linear regression analysis. Among all, the distance to settlement was found to be the best predictor for degradation in the study area.","PeriodicalId":45615,"journal":{"name":"Cogent Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23311843.2020.1801218","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41522325","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}

Surface water is becoming highly susceptible to pollution, and the trend of production of groundwater for various purposes has been increased from time to time. Groundwater will also be vulnerable to contamination by natural processes and anthropogenic disturbances and, thus, deserves appropriate attention and action. In the present study, spring water samples were collected from the Ankober district in low-, middle- and high-altitude areas in dry, semi-dry and wet seasons in 2015. Bacteriological (total coliform [TC] and fecal coliform [FC]) and physicochemical parameters such as temperature, pH, electrical conductivity, total dissolved solids, dissolved oxygen, salinity, total alkalinity (TA), total hardness (TH), Na+, K+, Ca2+, Mg2+, Fe2+, Mn2+, Cl−, SO4 2−, CO3 2−, HCO3 −, NO3 − and F− were analyzed to assess its suitability for domestic purposes. The results of the study showed that most of the parameters were found to be within the safe limit values of the WHO and Ethiopian standards for drinking water except some values at the lowest attitude area: TC/FC (147/1 per 100 ml) and F− (1.68 mg/L) in the dry season, Mg2+ (52.1 mg/L) in the semi-dry season and K+ (1.59–51.15 mg/L) in all three seasons. Furthermore, the values of Fe2+ (0.448–1.005 mg/L) were above the limit in most of the samples. Generally, spring water in the assessed areas is safe for domestic applications with slight variability in the low-altitude area. For sustainable use, vulnerability mapping and awareness creation are strongly recommended.","PeriodicalId":45615,"journal":{"name":"Cogent Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23311843.2020.1791461","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47369649","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}

Twelve key informant interviews and six focus group discussions were conducted in three selected communities within Nawalparasi District. This was further complemented by six expert interviews. The analytic hierarchy process (AHP) was employed to rank within and between groups of developed factors and their criteria. Users’ identified increased forest products (58%), community development (55%), employment opportunities (65%), and intense silviculture management (51%) as the dominant factors linked to the ecological, social, economic, and technical criteria, respectively. For between groups, economic (52%) and social (33%) criteria got the highest ranking. The findings suggest that the long-term success of this modality cannot be achieved if the users largely view it as economically and socially profitable.

This study used LANDSAT data to spatially assess the extent of urban expansion and its effect on land surface temperature within Kumasi, Ghana. Subsequently, the results showed significant changes in the land cover, which had an effect on the observed land surface temperatures from 1986 to 2015. Generally, there was an overall increase in the built-up areas by 24.13% (55.81 km2) from 1986 to 2015, with a corresponding increase in the mean land surface temperature by 4.16°C. As such, there is the need for the adoption of sustainable urban planning strategies with green vegetation conservation initiatives for modern city planners. This would help reduce urban land surface temperatures while promoting clean air circulation within the city.","PeriodicalId":45615,"journal":{"name":"Cogent Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23311843.2020.1787738","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48690843","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}
