   Sammanfattning : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

3. 2. Solid-phase Microextraction and Detection of Organophosphate Triesters in Indoor air

   Författare :Sindra Isetun; Ulrika Nilsson; Anna-Karin Borg-Karlsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SPME; Organophosphate triesters; flame-retardant; indoor air; Analytical chemistry; Analytisk kemi;

   Sammanfattning : In the work underlying this thesis solid-phase microextraction (SPME) was evaluated as a passive sampling technique for organophosphate triesters in indoor air. These compounds are used on a large scale as flame-retarding and plastizicing additives in a variety of materials and products, and have proven to be common pollutants in indoor air. LÄS MER
