  4. Occurrence and fate of Adsorbable Organic Halogens (AOX) in two WWTPs from Romania

    • Wed, 04/20/2022 - 04:00
    • Archives of Environmental Contamination and Toxicology
    • Absorbable organic halogens (AOX) are a global parameter which refers to a group of chemical compounds that contain one or more chlorine, bromine or iodine atoms in their molecule and can easily adsorb on activated carbon. The global concern related to the occurrence of the AOX compounds in the environment is due to their toxic and mutagenic effects on aquatic organisms and their potential role as inhibitors of microorganism growth, even at AOX low concentrations.

  18. Metal Accumulation and Ion Regulation in the Fish Hyphessobrycon luetkenii Living in a Site Chronically Contaminated by Copper: Insights from Translocation Experiments

    • Wed, 10/20/2021 - 02:01
    • Archives of Environmental Contamination and Toxicology
    • Fish living in the João Dias creek (southern Brazil) have to deal with trace-metal contamination in the long-term basis, as this aquatic environment has been historically impacted by copper mining activities. In order to survive in this harsh environment, the local biota had to develop adaptations related to pollution tolerance. The aim of this study was to test if biochemical mechanisms related to osmoregulation were among these adaptations, using translocation experiments.

  21. Microplastics Contamination in Commercial Green Mussels from Selected Wet Markets in Thailand

    • Sat, 09/11/2021 - 02:01
    • Archives of Environmental Contamination and Toxicology
    • Mussels have been identified as sentinel organisms (around the world) that indicate microplastic (MP) pollution. Since they are filter feeders, they easily uptake MPs. Mussels sold in commercial markets have been identified as an ideal way to directly quantify human exposure to MPs through seafood consumption. There are no studies reported on MP contamination of market-sold species in Thailand.

    • Archives of Environmental Contamination and Toxicology
    • In this study, the occurrence of 16 polycyclic aromatic hydrocarbons (PAHs) was investigated in 31 household dusts that were sampled from 27 areas located in 10 provinces, China. The total concentrations of PAHs (∑ PAHs) were in the range of 613–10,111 ng·g−1 with a median of 2565 ng·g−1. The predominant PAHs were 2 to 3 ringed compounds, accounting for 85.3% of ∑ PAHs. The geographical location had little impact on the contents of PAHs.

    • Archives of Environmental Contamination and Toxicology
    • Khetri Copper Belt, Rajasthan, is anthropogenically active and geologically belongs to the Delhi super-group. A study was designed to understand the geochemical processes controlling the elemental mobility in the groundwater. Sampling sites were divided into three zones, i.e. copper, quartzite and granite mine zones depending on the type of mineral excavated. A total of 32 representative groundwater samples were collected and analysed for heavy metals and radionuclide (U) using ICP–MS.
