Développement d’une méthode d’extraction des contaminants émergents dans les solides particulaires par LDTD-APCI-MS/MS

摘要: We developed a protocol to quantify 12 emerging contaminants (pharmaceuticals and hormones) pesticides extracted from suspended particulate matter (SPM) of river water municipal wastewaters samples. The separation solids was carried out through filtration tested series 6 different filter types. effect on the concentrations dissolved evaluated in order minimize losses target compounds. bottom sediments samples were lyophilized both SPM sediment subjected ultrasonic extraction combined with C18 cartridge clean-up. Quantifications realized using mass spectrometry. overall method recoveries all compounds ranged 38 112 % studied matrix, poor achieved for sulfamethoxazole diclofenac (recoveries other WWTP 68 111%). detection limits analytes varied 0.7 9.4 ng g -1 21 92 All detected ranging 3 5440 matrices, highest observed A significant portion some those is clearly associated or particulates. Optimization treatment processes environmental fate must absolutely consider fraction which particulate-bound if one hopes have reasonable balance.
