  • Emission of N2o from Polycyclic Aromatic Hydrocarbons contaminated soil at different water contents added with vermicompost

    Vermicompost is typically applied to improve soil quality, but can be used to remediate hydrocarbon-contaminated soils. Little information is available on how contamination and subsequent bioremediation with vermicompost affects emissions of N2O and CO2, important greenhouse gases. A sandy loam soil with different water contents (40%, 60%, 80% and 100% of water holding capacity (WHC)) was ...

  • Nitrous Oxide – a Powerful Greenhouse Gas with a Wastewater Treatment Connection

    ABSTRACT Although a ubiquitous element in nature, nitrogen has the potential for far-reaching environmental significance when considered in the context of the fate and impact of its various compounds in aquatic and atmospheric environments. Nitrous oxide (N2O) is a nitrogen compound largely unknown to the wastewater industry, but is a powerful greenhouse gas (GHG) due to its efficiency at ...

  • Advanced Gas Detection Technology supports Arctic Greenhouse Gas Research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...
