Distribution in marine fish and EDI estimation of contaminants of emerging concern by vortex-assisted matrix solid-phase dispersion and HPLC-MS/MS

Autor: Karina Lotz Soares, Adrià Sunyer-Caldú, Ednei Gilberto Primel, Gilberto Fillmann, M. Silvia Diaz-Cruz

Due to their persistence or continuous discharge, toxic substances are present in the aquatic environment, and can bioaccumulate and biomagnify in the food web, generating a significant ecological risk and a threat to human health. The present study

Sample as solid support in MSPD: A new possibility for determination of pharmaceuticals, personal care and degradation products in sewage sludge

Autor: Karina Lotz Soares, Sergiane Souza Caldas, Maristela B.R. Cerqueira, Ednei Gilberto Primel

Publikováno v: Chemosphere. 211

A method based on matrix-solid phase dispersion (MSPD), focused on the principles of green analytical chemistry, aimed at the use of alternative solid supports and less toxic solvents, was developed for the simultaneous determination of 19 pharmaceut

Dispersive liquid-liquid microextraction with solidification of floating organic droplets for simultaneous extraction of pesticides, pharmaceuticals and personal care products

Autor: Liziane Cardoso Marube, Sergiane Souza Caldas, Ednei Gilberto Primel, Karina Lotz Soares

Publikováno v: Microchimica Acta. 182:1765-1774

Dispersive liquid-liquid microextraction based on solidification of floating organic droplets (DLLME-SFO) has been applied to the extraction of pharmaceutical and personal care products (PPCPs) and pesticides from water samples. The PPCPs included bi
