The results of monitoring non-dioxin-like PCBs in beef and pork in the Czech Republic

The assessment of results for non-dioxin-like polychlorinated biphenyls (NDL PCBs) in the years 2009–2011 and 2012 demonstrated average concentrations of NDL PCBs in a range of 6.13 to 10.34 ng.g-1 of fat in beef and 5.48 to 8.02 ng.g-1 of fat in pork. For highly chlorinated PCBs, the average values of individual congeners were ranked in order 153 > 138 > 180. Congeners with a lower number of chlorine atoms (PCBs 118, 52, 101 and 28) were found in low concentrations or beneath the limit of quantificatio.
