  • An adaptive, comprehensive monitoring strategy for chemicals of emerging concern (CECs) in California's aquatic ecosystems

    A scientific advisory panel was convened by the State of California to recommend monitoring for chemicals of emerging concern (CECs) in aquatic systems that receive discharge of municipal wastewater treatment plant (WWTP) effluent and storm water runoff. The panel developed a risk‐based, screening framework that considered environmental sources and fate of CECs observed in receiving waters ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...
