A LOW-COST OPEN HARDWARE SYSTEM FOR COLLECTING TRAFFIC DATA USING WI-FI SIGNAL STRENGTH


Two methods of sample preparation for analysis of non-ortho and mono-ortho PCB congeners in the muscles of selected fish species

Background.Polychlorinated biphenyls (PCBs) are persistent organic pollutants widespread in the environment.Their ability to accumulate in living organisms leads to food contamination, which is the main route of human exposure to PCBs.During analytical procedure of PCB residue determination, losses of these compounds may occur, which contribute to
