  • Retraction Note: Field evaluation of intensive compost application on Cd fractionation and phytoavailability in a mining-contaminated soil 2019-06-18

    The Editor-in-Chief has retracted this article (Li et al. 2016). An investigation by the Journal has not been able to confirm the identity and affiliation of the author David Raleve. This author was the corresponding author on submission but changed the corresponding authorship at the proof stage. The current corresponding author was not aware of the publication of this article. As the appropriate authorship for this article cannot be determined, the Editor-in-Chief no longer has confidence in this article. Ibrahim Mohamed disagrees with this retraction. Ming Li and Wenli Chen did not respond to any correspondence about this retraction. Qiaoyun Huang did not respond to any correspondence about this retraction notice.

  • Perlite as the partial substitute for organic bulking agent during sewage sludge composting 2019-06-18

    Abstract

    Composting is an efficient and cost-effective technology for sewage sludge treatment, and bulking agents are essential in sewage sludge composting. In this study, perlite was chosen as inorganic bulking agent to partially substitute for the organic bulking agent. Variations in the temperature, bulk density, moisture content, pH, electrical conductivity, organic carbon, nitrogen, phosphorus and potassium were detected during sewage sludge composting. The treatment with a mass ratio of spent mushroom substrate to perlite at 3:1 exhibited the highest pile temperature and the best effect on reducing bulk density and moisture content. In addition, Fourier transform infrared spectra showed that perlite promotes the degradation of organic matter during the composting process, and the germination index showed that the compost from all treatments was safe for agricultural application. When the mass ratios of spent mushroom substrate and perlite at 3:1 and 2:2 were chosen as bulking agents, the sewage sludge compost product could be used to produce plant cultivation substrate, and economic benefits could be obtained from sewage sludge composting according to comprehensive cost analysis.

  • A scoping study of component-specific toxicity of mercury in urban road dusts from three international locations 2019-06-18

    Abstract

    This scoping study presents an investigation of the total and bioaccessible mercury concentrations in road dust (RD) from three international urban sites, where a one-off sampling campaign was conducted at each. This was done to address the hypothesis that the matrix in which mercury is found influences its ability to become accessible to the body once inhaled. For that purpose, the samples were analysed for total and pulmonary bioaccessible mercury and the data compared to the chemical structure of individual particles by SEM. The results obtained from this study suggest that a high mercury content does not necessarily equate to high bioaccessibility, a phenomenon which could be ascribed to the chemical character of the individual particles. It was found that the Manchester samples contained more pulmonary soluble mercury species (as determined by elemental associations of Hg and Cl) in comparison to the other two samples, Curitiba, Brazil, and Johannesburg, South Africa. This finding ultimately underlines the necessity to conduct a site-specific in-depth analysis of RD, to determine the concentration, chemical structure and molecular speciation of the materials within the complex matrix of RD. Therefore, rather than simply assuming that higher bulk concentrations equate to more significant potential human health concerns, the leaching potential of the metal/element in its specific form (for example as a mineral) should be ascertained. The importance of individual particle behaviour in the determination of human health risk is therefore highlighted.
