Negative Effect Of Ponds Water On Environment
Abstract
This study assesses the rainwater ponds with comparison of water samples were taken back from the rainwater right after it fell. In addition, it will investigate the effect of negative effect of ponds rain water. After rainwater falling to the ground and being exposed to natural or industrial activities. This work examined this water Chemical, Physical and Biological properties. Field experiment was conducted in Misurata region in central Libya. The ponds rain water physicochemical parameters such as, acidic number (PH), Total dissolved salts (TDS), Electrical conductivity (E.C), Sulphates (So4-2), Nitrates (No3), Ca, Mn and Fe also determined. Fungal colonies were isolated and counted. The results reveal that sampling sites were affected by different activities waste. Total soluble salts of ponds rain water and control ranged from 24.6 to 524 ppm and the pH ranged from 7.1 to 8.4. and showed appreciable differences within localities. Electrical conductivity presented 39.0 to 819 ppm. Whereas the Sulphates, Nitrates showed 0 to 30 ppm,0 to 30.5 ppm respectively. The all tested metals increased from all locations. Isolated microbial flora consists of 4 fungal genera belonging to, Aspergillus, Penicillium, Rizopus and Fusarium. Most of them may consider the resistance fungi to industrial waste water due to its large colonies numbers isolated from unclean rainwater ponds water and contaminated metals area. In conclusion the human activities had a significant effect on all the parameters examined even microbial flora.
