  • Abstract

    This study was conducted in Cote d’Ivoire as part of a three steps study to assessing the environmental impacts of fish production in extensive farming using rice bran feedings, through a life cycle analysis. The feeding results indicated that processed rice bran feeds did not show better yield compared to the non-processed rice bran. Using the nutritional balance method, the rate of N and P uptake by fish were 8.5% - 18% and 21.5% while it was 14.5%-18% and 3%-4.5% using the nutritional balance method. The most important environment potential impacts were non-renewable energies use (84.80 – 119.55%), global warming (5.51 -7.43%), and eutrophication (-26.83 – 8.40%) The impact of one ton of “ready to sale” Tilapia fish ranged from -477,90 to 963,11 kg PO4-eq for eutrophication, 1451,77 to 846,51 kg CO2-eq for global warming potential, and 1451,93 to 10498,03 MJ for non-renewable energy use. For the potential impact for eutrophication, the most important contribution came from the production of fish at the farm level (> 96%) while for non-renewable energies use, rice bran contributed significantly to this impact (47-81%) followed by infrastructures (47 - 81%). For global warming, rice bran production is the major contributor (59 - 76%). These results indicated that LCA is suited for the analysis of various flows of materials and energies that cause environmental pollution of extensive fish farming in Côte d'Ivoire.

  • Abstract

    This study was carried out to determine the prevalence of mastitis in lactating Dairy Cow at District Dairy Farms in Sylhet and UVH, at Jaintapur during the period of January 2016 to December 2016. Mastitis was most frequently seen in cross breed cows. In Jaintapur Upazilla, most of cows were indigenous, but there were many farmers rear cross breed cow for the purpose of selling milk in market. In Dairy Farm, all cows were cross breed. The overall prevalence was higher in crossbred cows than indigenous cows. The prevalence of mastitis was higher in advancing age and in lactation period. The cows were more prone to mastitis during 1st month of lactation. There was significant relationship between prevalence of mastitis and associated risk factors like general physical condition, herd size, frequency of dung removal, floor drainage quality and condition of floor. Reproductive diseases and periparturiant diseases showed higher incidence of mastitis in cows. The overall prevalence of mastitis at Jaintapur was 7.15%. The prevalence of mastitis of dairy cows in Jaintapur Upazilla was more in rainy season and less in winter season. The prevalence of mastitis was 3.47% in summer season, 11.52% in rainy season and 5% in winter season. The overall prevalence of mastitis at Dairy farm was 6.91%. The prevalence of mastitis in dairy farm was more in rainy season and less in summer season. The prevalence of mastitis was 4.97% in summer season; 16.53% in rainy season and 5.29% in winter season.

  • Abstract

    This paper was for confirm "Regular assessment of groundwater (GW) to assist health and economic development in Saudi Society (SS), "VISION 2030 G", Taif, KSA", highest turbidity were in GW samples (3, 6 and 10), all samples had pH values falling standards. Electric Conductivity (EC) revealed 20% samples were above standards. The salinity was considered unsuitable for drinking samples (3, 4 and 10), Total Hardness (TH) was high in samples (3, 4 and 10). Calcium Carbonate (CaCO3) ranged (55-2793) mg L−1 in 30%, Chlorides (Cl) ranged (18-1759) mg L−1 in 30%, Sulfates (SO42−) ranged (33-2245) mg L−1 in 90%, Nitrates (NO3) ranged (0-60) mg L−1 in 80% of GW samples. The bacteria were present in all GW samples except sample 2, one bacterial type was in sample 3, and others had two types. Gram positive bacteria found in all except sample 3, either joined Gram negative samples except samples (1, 2, 3, 6 and 7). The colony count were ranged (1.5X103-5.5X104) CFU/mL. The bacteria of Gram positive were (Staph. spp and Micrococcus spp) and Gram negative were (E. coli and Klebsiella spp). That concluded the variations in GW samples with standards, that need foxed in uses or treatment. The presence of faecal contamination can cause infection and food poisoning or toxic production that will affect SS. The recommendation is to "MOH and MOIAL", to regular follow up GW quality at high altitude (HA) area using for "human, animal, birds and plant resources" to protect the community health (CH) and helping SS.

  • Abstract

    Marine pollution is now considered as a worldwide issue due to the continuous industrial and domestic discharge. These discharges seriously damage the marine habitat and affect the aesthetic view. In this research samples were carried out using conventional method from marked locations. Screening was carried out using various biochemical tests.. The comparative analysis of the water quality and spatial variation of Sandspit was done. Sandspit is influenced greatly by industrial waste water. The sampling point’s closer to waste discharge indicated higher incidence of total heterotrophic bacteria, coliforms, Staphylococcus aureus, Bacillus spp and Salmonella spp .Escherichia coli and Pseudomonas aeruginosa was dominant in Sandpit’s water samples. Chemical parameters such as COD and BOD, result indicates water bodies are being highly polluted with waste water effluent of the city.

  • Abstract

    The biometric parameters of Achatina fulica living on five bays of the Ebrié lagoon of Abidjan were the subject of this study. The five bays chosen for this study are: the berries of Azito, Banco, Cocody, M'badon and Anan. Another area blessed with the same climatic conditions was chosen as a control site. A sample of 50 snails was collected per site. The living masses, the masses of shells, consumable flesh, and viscera of these snails have been noted and compared. Soil samples from the different snail collection sites were collected and assayed in metallic trace elements (ETM). The results showed that the biometric characteristics of snails decrease with the increase of soil ETM content in the living environment. Thus, the living mass, empty shell, consumable flesh and visceral mass are strongly influenced by the concentration of soil ETM.

  • Abstract

    Drinking water is the largest contributor of fluoride in daily intake. Dissolution of fluoride-containing rock minerals is the source of naturally occurring fluorides in groundwater whereas application of phosphate fertilizers or sewage sludges or pesticides are the artificial source of fluoride in groundwater and surface water. The major objective of this study was to locate the vulnerable areas in terms of fluoride contamination. A total of 60 groundwater samples were collected from tubewells of five development blocks of Dhemaji district of Assam in one year period, during December 2016 to November 2017 using GIS technique. The present study showed that fluoride content in the groundwater samples ranges from 0.54 to 0.89 mg/L. The highest fluoride value (0.89 mg/L) was recorded at sampling points A-7 and B-9. The fluoride concentrations in all samples were found to be within the permissible limit of WHO (1.0 mg/L) but in some locations where the fluoride concentration in water was less than 0.7 mg/L may cause dental carries. Significant variation was observed between pre-monsoon (October to April) and post-monsoon (May to September). Fluoride concentration is sufficiently higher in post-monsoon than in pre-monsoon season. Since the groundwater is the only source of drinking water in the area, proper treatment strategies and regulating the groundwater extraction are required as the quality deterioration poses serious threat to human health.
