The study was based on understanding the community's perceptions on the presence of heavy metals in their surroundings. At Lugelweni, Mt Ayliff there are abandoned copper mines located at Intsizwa Mountain which might be a potential source of metal contamination to Lugelweni community. The participants at Lugelweni village in Mount Ayliff were randomly selected and a questionnaire was distributed for assessing their awareness on the presence of the mines. The results showed that the participants do not know exactly when the process of mining started at Lugelweni and most of the participants were living in the area when the mining process was abandoned. Many participants agreed that there is water found at the mining area and do not know if the water is clean or not. About 60 % of the participants do not know if the metals from the mines might be harmful to the environment or not. More than 80 % of participants disagree that the metals leaching from the mines can be found in their agricultural soils. The results are an indication that the community members from Lugelweni Mt Ayliff are aware of the presence of the abandoned mines at Intsizwa Mountain. They are not aware of the effects that the metals from the abandoned mines might have on humans, agricultural soils, water, plants, and animals. There is a need for the South African Department of Environmental Affairs to conduct awareness campaigns in the areas where the abandoned mines are located.
Escherichia coli is a Gram-negative bacterium also found in the human. Bacillus subtilis is a Gram-positive, non-pathogenic, endospore-forming bacterium. The spores can survive the heat and B. subtilis to cause food poisoning. The study hypothesized that the extracts from B. pilosa would inhibit the growth of E. coli and B. subtilis. The seeds of B. pilosa were purchased from the seed company. The seeds were dried, ground, and shaken in acetone, ethanol, methanol, and water for 72 hours. Solvents were evaporated and the crude extracts were used for antibacterial activity using a modified Kirby-Bauer disc method. The results revealed that the growth of E. coli was inhibited by the extracts using ethanol. The zones of inhibition were 13 mm. The extracts that were extracted using acetone and water were not effective in inhibiting the growth of E. coli. The growth of B. subtilis was inhibited by the extracts from acetone and methanol. The zones of inhibition were 13 mm. The results revealed that the extracts from ethanol and water were not effective in inhibiting the growth of B. subtilis. Seeds of B. pilosa have the potential to be used as antimicrobials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
