Selected perfluorinated compounds in the sediment of an arctic freshwater lake: A case study at Kapp Linnè
Lunde, Stig Magnus (Master thesis, 2016-08-10)After their discovery in the environment in the early 2000s, polyfluorinated alkylated substances and perfluorinated alkylated substances (PFASs) received much attention because of their persistence, bioaccumulation ... -
Short and medium chain chlorinated paraffins in atmospheric samples : analytical challenges
Nipen, Maja (Master thesis, 2017)Chlorinated paraffins (CPs) is a group of organic compounds consisting of chlorinated n-alkanes of varying chain length (C10-C30) and degrees of chlorination (40 to 70% by weight). The CPs are generally divided into three ... -
Small-scale on-site treatment of fecal matter: comparison of treatments for resource recovery and sanitization
