    Abstract: Heavy metals pollution on the environment (seafood and humans) is a global problem. The concentrations of copper, cadmium and chromium in prawns, periwinkle and croaker fish from Aba area of Abia State were determined using Atomic Absorption Spectrophotometric (AAS) techniques. The values of copper in periwinkle, prawns and croaker fish were 19.22±... Show More

    DOI: 10.11648/j.ajese.20180204.12
    Abstract: This study was aimed at evaluating the effect of mass transfer resistance to the transport of phenol in soil sediments. Batch adsorption experiments were conducted using phenol in homogenous soil sediments (clay and sand). The Physico-chemical properties of the soil sediments were determined and sorption behaviour kinetically modelled using the Pse... Show More

    Abstract: Nowadays, the continuous fog and haze weather has made people more and more concerned about air pollution.And the air pollution problem in the Beijing-Tianjin-Hebei region is the highest in China. The high-density population distribution, crowded urban traffic and large-scale heavy industry bases are the main reasons for this phenomenon.This study ... Show More
  • Preliminary Bioleaching of Heavy Metals from Contaminated Soil Applying Aspergillus niger F2

    DOI: 10.11648/j.ajese.20180204.14
    Abstract: A new strategy of heavy metal biobleaching was proposed based a fungal strain identified as Aspergillus niger and named F2. F2 displayed great ability of heavy metal resistance and organic acid production. The temperature, pH, carbon source, and nitrogen source have great influences on the heavy metal bioleaching from contaminated soil by F2. The o... Show More
