This paper examines the socio-economic and environmental impacts of stone mining in Shivpuri district. A large number of people are dependent on stone mining activities for carrying their livelihoods as stone mining is one of the most economic activities after agricultural practices in Shivpuri district. A high quality stone belt is spread around 100 km area from west to east. Meanwhile, about 60% stone mines are located in the Madhav National Park and other forest areas of the district. Due to large-scale extraction of stones from the forest area, depletion of biodiversity resources was enormous. And as a result, the mining practices were banned and this led to worst socio-economic conditions of the poor rural people. This study also attempts to penetrate the exclusive solutions that support both mining activities for carrying livelihoods and environmental restoration through large-scale plantation campaign. It reveals that if appropriate measures are taken place, mining practices and environmental restoration can go parallel. This study was conducted through collection of data from the primary sources. A case study of the five villages through household level survey was conducted during the years 2009-2011.

In the recent decades, flax fibres can be used as laminate reinforcements with polymer matrix materials to form natural composites, providing outstanding environmental benefits and other characteristics such as reduced cost and light weight. The composite properties are limited by the poor natural fibre/polymer matrix adhesion, which could be improved by chemical modifications. The fibre properties, such as thermal and mechanical properties, after the treatments have a direct effect on the composite behaviors. In order to investigate the effect of treatments on fibre properties, non-woven flax fibre mats were subjected to alkali, esterification and silane treatment. Fourier transformation infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and tensile tests were conducted on the virgin and treated flax fibres. It was found that all the treatments resulted in the removal of pectin and lignin component within the primary cell wall as evidenced by the characteristic IR peak change. The results showed that the thermal stability of non-cellulose part of flax fibres was highly improved by esterification modifications. However, the decrease (20-30%) in fibre tensile properties after the treatments was possibly offset by the improvement in fibre/matrix adhesion.

DOI: 10.9734/JSRR/2015/12884

The aim of the study was to assess occupational noise levels in a plastic manufacturing industry in Zimbabwe between April 2014 and July 2014. The research followed an experimental design set up. Three sites were selected (1, 2 and 3) and each site had three sampling points randomly selected where the measurements were done. One out of two workers per site (three sites in total) was chosen and occupational noise levels were measured using a sound level meter which was calibrated. Measurements were done at hourly intervals for 8 hours. These were done for five days a week during the three weeks per month for a total period of three months. In order to determine the Time Weighted Average (TWA), a formula was used for the calculations. Results showed that the average noise levels ranged from 89–96 dBA among the study sites. Results from ANOVA showed that there was no significant difference in the TWAs among the sites (F=1.67; df=2 and 126; P=.19), among the workers (F=.17; df=2 and 126; P=.54) and the interaction of site and worker (F=1.67; df=4 and 126; P=.16). The one sample t-test for comparison of the 8hr TWA noise levels with the national and International standards showed that the mean TWA was significantly higher than the Zimbabwean standard by a mean difference of 3 dBA (t=15,79; df= 134; P<.0001). The mean TWA was also significantly higher than the International standard by 8 dBA (t=41.53; df= 134; P<.0001). The present findings suggest that the noise levels in the plastic manufacturing industry under study were high in all the three sites. Workers are exposed to noise levels which are above the international legislated occupational level.

Aim: To determine the level and distribution of Zn, Cu, Ni, Cr, Pb, Hg and V from soils in the vicinities of Kakuri industrial area of Kaduna state, Nigeria.
Study Design: To compare the soil heavy metal concentrations with regulatory standard values permitted by the Nigerian environmental guideline as well as international standards and also subject the data to descriptive analysis to determine the Geo-accumulation index (Igeo) and contamination factor (Cf).
Place and Duration of Study: Department of Chemistry, Ahmadu Bello University Zaria between February 2012 and July 2013.
Methodology: Twenty six soil samples at 0 to 10cm and 10 to 20cm depths from twelve (12) sample locations and two control samples was collected on the same day at Kakuri industrial area of Kaduna, Nigeria. The total concentrations of Cu, Zn, Pb, Cd Ni, Hg and V was determined using XRF spectrophotometer. Organic matter content (OM), pH, calcium carbonate and particle size distribution of the soil samples were also determined.
Results: The mean concentrations (in mgkg-1) of Zn, Cu, Ni, Cr, Pb, Hg and V are 100.5±19.82, 60.02±3 .60, 26.25±6.44, 42.42±5.21, 32.00±1.68, 28.80±9.35 and 73.08±3.52 respectively. The metal concentrations (in mgkg-1) ranged: Zn, 20-420; Cu, 26-110; Ni, 9-72; Cr, 22-157; Pb, 27-34; Hg, 10-60 and V, 47-120. Zn and Cu correlated positively with pH with values +0.41643 and +0.64447 respectively. Zn and Cu (+0.6142) and also Zn and Hg (+0.6377) had strong correlation which signifies the same source(s) in the soil. The contamination factor Cf values 1.31, 1.40 and 1.70 for Zn, Cu and Pb respectively falls under the classification 1 ≤ Cf Ë‚ 3 indicates the soil is considerably contaminated but the Igeo ≤ 1 for all sample locations with the exception of KGW with 1Ë‚ Igeo ≤ 2.
Conclusion: Significant spatial variation in concentrations was observed for all metals across the locations and the degree of pollution varies with the level of industrial activities but were all within tolerable limit. The contamination factor C and Igeo index confirms the soil is uncontaminated.
