Abstract

Water is also a vital resource for agriculture, manufacturing and other human activities. In urban areas, the careless disposal of industrial effluents and other wastes into rivers may contribute greatly to the poor quality of river water. This research is to assess the level of heavy metals (Cd, Cu, Mn, Ni, Pb and Zn) in Catfish-Clarias gariepinus and the sediment from River Benue at Ibi, Taraba state, Nigeria. The level of heavy metals in water, sediment and catfish from the study area were assess and the estimate contamination factor and pollution load index in the sediment of the study area was also access and compared with the WHO results and other relevant standards. The results shows that the concentration of heavy metal in fish was within the WHO permissible limits. Also the concentration of Pb, Zn and Ni in catfish were significantly (P≤0.05) higher compared to the metals but they were within the WHO permissible limits except for Cd. Heavy metal concentrations in sediment were within the acceptable WHO and USEPA limits, except for Cd, and Mn. PLI values for sediment from all the sites were less than one, implying that the sediment was unpolluted. The persistence of heavy metals in water, fish and sediment samples from the studied areas over time might lead to potential health risk on both humans and aquatic lives via food ingestion. Changes in water and sediment chemistry might be responsible for the variations in the chemical properties of sediment, water and fish.

Abstract

The escalating issue of plastic waste, particularly polyethylene terephthalate (PET), poses significant environmental challenges in Nigeria due to its resistance to natural degradation. This study aims to investigate the feasibility of recycling waste PET into composite materials by incorporating sand sourced from three distinct locations. Composites were formulated by blending PET waste with sand in varying ratios, designated as samples A, B, and C. We meticulously evaluated the mechanical properties of these composites, focusing on impact strength, compressive strength, tensile strength, and hardness. The findings reveal that increasing sand content correlates with a decrease in impact strength, a trend consistent across all samples as PET content diminishes. Although compressive strength initially exhibits a slight increase with additional sand, it ultimately enhances with greater PET proportions. Conversely, tensile strength experiences a modest rise with increased sand and a significant improvement with elevated PET levels. Notably, hardness decreases with rising sand content but improves with higher PET levels. These results highlight the potential of PET-sand composites as sustainable construction materials, representing a practical approach to mitigating plastic waste while contributing to eco-friendly building practices.
