  • Use of methyl esterified eggshell membrane for treatment of aqueous solutions contaminated with anionic sulfur dye

    The present study assessed the adsorption of an anionic dye (sulfur blue) by methyl-esterified eggshell membrane (MESM), a low-cost and abundant material from waste. Adsorption kinetics were investigated using parameters such as pH, contact time, initial dye concentration, solution temperature, dosage of adsorbent, and particle size of adsorbent. After methyl esterification, the specific ...

  • Energy capture and nutrients removal enhancement through a stacked constructed wetland incorporated with microbial fuel cell

    To improve the sustainability of constructed wetlands (CWs), a novel tiered wetland system integrated with a microbial fuel cell (MFC) was developed in this study. Compared to the single stage CW, chemical oxygen demand (COD) removal efficiency was improved from 83.2% to 88.7%. More significantly, this tiered system significantly enhanced total nitrogen removal efficiency (an increase from ...

  • Sensitivity of six subantarctic marine invertebrates to common metal contaminants

    A long history of anthropogenic activities in the relatively pristine subantarctic has resulted in areas of accumulated waste and contaminants. Sensitivities to metals of subantarctic and Antarctic species may contrast with related species from temperate and tropical areas, due to the unique characteristics of polar biota. In addition, response to contaminants may be delayed and hence longer ...

  • Quantification of exposure to fecal contamination in open drains in four neighborhoods in Accra, Ghana

    In low-income countries, rapid urbanization adds pressure to already stressed water and sanitation systems that are critical to the health of communities. Drainage networks, designed for stormwater but commonly used for disposing of waste, are rarely covered completely, allowing residents to easily come into contact with their contents. This study used spatial mapping, documentation of ...

  • Turning Contaminated Waste into Clean Renewable Energy and pas 110 compost – an overview of the inter Engineering Biowaste Process

    The Inter Engineering Biowaste process has been specifically developed to allow contaminated CAT3 organic wastes to be pre-conditioned and anaerobicly digested to produce high yields of renewable biogas and good quality compost suitable for compliance with the proposed PAS110 standard.   The paper outlines the process and discusses many of the specific adaptations the process has made to ...


  • Detoxification of chromium slag and contaminated soil

    Chromium slag and contaminated soil are significant risks to human health. Their detoxification is a difficult problem. In this study, we tried to detoxify the chromium slag and contaminated soil by a solid reduction method. The final product is ceramist. The mechanism and process of detoxification of chromium slag and contaminated soil were studied. The residues of Cr (VI) are lower than 0.004 ...

  • Domestic fuel price and the Nigerian macroeconomy

    This study examined empirically a one–to–one nexus between domestic fuel price and various macroeconomic variables in Nigeria for the period spanning 1986 to 2011. The study adopted both a vector auto–regressive (VAR) and a vector error correction (VEC) models for appropriate analysis. For pairs of variables that are integrated of the same order but not co–integrated, the VAR model revealed that ...
