Abstract

Mining is known in releasing of heavy metals and environmental pollutants due to their toxicity, persistence in the environment, and bio-accumulative nature. Leaching activity of mining has a major role in releasing of chemicals which toxify to the mining environment. Such activity contaminates the terrestrial ecosystems with toxic heavy metals that lead to the environmental problem of public health concern. In Ethiopia, even the mining trend is accounted long time, the environmental and social impacts are underestimated and not taken as an issue for a long time. However, these impacts are become very risky and problematic from time to time, since mining companies are not dedicated to their environmental and social impact assessment commitments. Being persistent pollutants, heavy metals accumulate in the environment and consequently contaminate the food chains. Accumulation of potentially toxic heavy metals in biota causes a potential health threat to their consumers including humans. Phytoremediation is more cost-effective than alternative mechanical or chemical methods of removing hazardous compounds from the soil. Vetiver grass is a perennial grass belonging to the Poaceae family with short rhizomes and a massive, finely structured root system. The deep root system makes the vetiver grass extremely drought tolerant and very difficult to dislodge when exposed to strong water flow. The main purpose of this study is to review the ecological impacts of mining in releasing leached wastes/drainages/ and the possible and effective techniques of treatment via Phytoremediation technology.

Abstract

The aim of the present study was to evaluate the Chemical composition and bioactivity of Anthocleista schweinfurthii Gilg (Gentianaceae) fruits, leaves, root bark and stem bark extracts against Sickle cell disease (SCD) and associated bacteria. The antisickling and antibacterial activities were carried out using Emmel and micro-dilution methods respectively. The results revealed that the fruits, leaves, root bark and stem bark extracts  of A. schweinfurthii contains various secondary metabolites such as the alkaloids, saponins, total polyphenols, flavonoids, tannins, anthocyanis, leuco-anthocyanins and quinones.  The ethyl acetate and methanol extracts displayed antisickling activity. While, the antibacterial activity of different plant extracts tested was weak toward tested bacterial strains (CMI ≥125μg/mL). The antibacterial activity can be improved by bio-guided fractionation of the n-hexane, ethyl acetate or methanol soluble fraction. This study provides for the first time a scientific basis for the in vitro antisickling activity of A. schweinfurthii.

Abstract

The aim of this research was to investigate the vegetation characteristics to determine the dominant species because the selected study area never has been ecologically studied before. The study was carried out in the period from April to the end of May 2018 two trips per week. To achieve the study, two methods were used Quadrat Method and Lines-transect Method. 19 lines-transect were randomly distributed with a length of 50 meters in the study area. A total of 92 quadrats 4 m2 selected for perennial plants and 60 quadrats 1 m2 for annual plants (grasses) were distributed to the Line-transect; all plant species and their numbers that appeared in the quadrat were recorded. Vegetation characteristics (density, frequency, and abundance) and their relative values of each plant species were calculated from quadrat, whereas cover and the relative cover was calculated from Line-transect. The results showed that the highest density in annual plants was 32.1 plant / m2 for Stipacapensis followed by Scabiosaarenaria with 15.6 plants /m2, while in perennial plants was found (14.7 plant / m2) for Plantagoalbicans followed by Helianthemumlippii  density with (3.26 plant / m2). The obtained results also showed that S.Arenaria has the highest frequency 80%, then S. capensis with 78.30% in annual plants, in perennial plantsP. albicans  has the highest frequency (97.8%) followed by H. lippii  with (70.6%). It appears from results obtained that the highest cover recorded was (15.8%) for S. capensis followed by P. albicans (12.4%).  From the results, the annual plants have the highest value were 187.92 for plant species S. capensis followed by S. arenaria with 148.8. Through the results obtained, the plantcommunity of the study area is Stipa capensis - Scabiosa arenaria Community.
