Previous studies have reported contamination of water and soil by acidic factory discharges laced with hazardous heavy metals and fluoride in Kerio Valley, Kenya. However, there is no data on Fluoride and selected heavy metals in food chain around Fluorspar mining Plant. This formed the motivation behind the study to avail the data on the level of contamination. The experimental design was an entirely randomized design where mutton, caprine, and plant (leaves, grass, corn maize) samples were randomly collected from the three locations (Tumeiyo, Choff, and Kimwarer) in three replicates and Turesia which was selected as the reference or control site. Sample preparations and analyses were done according to recommended methods. Fluoride levels were 6.34±2.45 mg/Kg and 9.58±6.03 mg/Kg in caprine and mutton, respectively. Heavy metals ranged between 0.06±0.02-0.06±0.03 mg/Kg for Pb, 0.06±0.03-0.09±0.06 mg/Kg for Cd, 3.31±1.90-3.66±2.41 mg/Kg for Zn, 0.51±0.32-0.82±0.55 mg/Kg for Fe and 0.44±0.28-0.54±0.33 mg/Kg for Cr. Fluoride levels in vegetation ranged between 4.77±2.52 and 6.27±3.40 mg/Kg, while heavy metal levels ranged between 0.01±0.01- 0.04±0.02 mg/Kg for Pb, 0.02±0.02-0.05±0.03 mg/Kg for Cd, 0.26±0.21-0.48±0.30 mg/Kg for Zn, 0.21±0.15-0.50±0.34 mg/Kg for Fe and 0.19±0.14-0.23±0.18 mg/Kg for Cr. Zn, Fe and Cr levels in meat and fluoride surpassed the WHO/FAO maximum limits while Pb and Cd in all the samples were within allowable limits. Conclusively, meat recorded higher analytes concentrations compared to vegetation. The fact that the levels of key chemical analytes in the assessed samples were availed and the contamination status indicated, presented the primary significance of this research. \u0000  \u0000Keywords: heavy metals; caprine, mutton; food chain; Fluorspar mining Plant","PeriodicalId":12792,"journal":{"name":"Greener Journal of Environmental Management and Public Safety","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82076896","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}

This work was carried out to comprehensively study the leachates from three Soluos dumpsites with a view of establishing correlation matrix for the leachate parameters in each of the dumpsites. The locations of the dumpsites were identified using Global Positioning System (GPS). Four different leachate samples were taken in each of the dumpsites and all the samples were analysed for thirty four leachate parameters according to the America Public Health Association (APHA). The results of the analysis were used to develop correlation matrices using the in-built Pearson product moment correlation coefficient solver tool in Microsoft Excel version 7. The results of the analysis reveal that some parameters such as biochemical oxygen demand, chemical oxygen demand, copper and chromium exceeded the permissible limits of the regulatory bodies. The correlation matrices showed a strong relationship among the leachate parameters and it was therefore recommended that the current practise of waste mix in the dumpsites should be stopped and the dumpsites leachates should be treated. \u0000  \u0000Keywords: Soluos dumpsites, solid waste, leachates, contaminants, correlation matrices.","PeriodicalId":12792,"journal":{"name":"Greener Journal of Environmental Management and Public Safety","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87554354","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}

Microsoft Excel and PAST software were employed to investigate the abundance and diversity of macro-invertebrates. Ephemeroptera was dominated 137(40.53%) followed by Coleoptera 112(33.14%) in the Teletele stream. However, other groups had less distribution. Based on the study sites, Ephemeroptera, Coleoptera and Diptera were the most widely distributed organisms accounted for 69(60%) at site 1, 28(17.1%) at site 2 and 40(67.8%) at site 3 for Ephemeroptera. Coleoptera comprised 22(19.1%) at site 1 and 90(54.87%) at site 2 and Diptera consisted 34(20.7%) at site 2 and 15(25.4%) at site 3. The distributions and compositions of the benthic macro-invertebrates were unequal at the sampling sites and statistically not significant (one way ANOVA, P>0.05). The Shannon diversity indexes were different among the sampling sites and the distribution of benthic organisms strongly associated with water quality parameters. The overall Shannon diversity index was (1.37) it revealed that the abundance and diversity of macro-invertebrate communities were low and therefore showed that poor water quality. At the study sites, several human induced associated impact problems like the existence of exotic Eucalyptus trees, Agricultural lands, waste material disposal and Ambo University’s oxidation pond were identified that resulted less distribution of macro-invertebrates in Teltele stream. The stream is vital for socioeconomic purposes such as drinking (cattle watering), sanitation, recreation, irrigation and others of the communities around the catchment and therefore, watershed management throughout the catchment is vital for proper utilization of the Teltele stream.
