The consequences of exposure of people to highly chlorinated polychlorodibenzo-p-dioxins (PCDDs) are much less known than those of TCDD. We report on levels of PCDDs (and PCDFs) in 13 members of two families poisoned by contaminated cooking oil. Orig

The present situation with respect to the exposure of the general human population to PCDDs, PCDFs and (dioxin-like) PCBs and specific issues that should be taken into consideration for a risk assessment of these exposures have been summarized. The i

We have studied the kinetics of lipid removal using the semipermeable membrane technique (SPM) during preparation of fat rich environmental samples for analysis of lipophilic substances such as dioxins. This is a useful alternative to the conventiona

Nine catfish fillets, three catfish nuggets, two feed samples, and one pond sediment were analyzed for PCDD, PCDF, and PCB. Farm-raised catfish from Mississippi, Alabama, and Arkansas contained significant levels of 2,3,7,8-substituted PCDD and PCDF.

During the summer 1995, we collected sewage sludge and effluent samples from 17 publicly-owned treatment works (POTW) in the State of Mississippi, USA. Most PCDDs and PCDFs were detected in the slu ...

Samples of virgin suspension PVc resin from eleven major production sites in Europe have been analysed by HRGC/HRMS for PCDDs and PCDFs using a dissolution method. The method has been validated in two laboratories, down to levels of detection of less

In 1994, we analyzed 43 foodstuff samples from local supermarkets in southern Mississippi, USA, for PCDD/PCDF. 2,3,7,8-Cl4DD could be quantified in 31 of these samples. On a lipid basis, levels in meat (0.53-1.10 pg I-TEQ/g) and dairy products (0.42-

In 1994, we collected 36 soil samples and 61 sediment samples from southern Mississippi, USA. Each sample was analyzed for PCDDs and PCDFs by HRMS using either a polar or a non-polar HRGC column. Although most Cl4 Cl8 PCDDs and PCDFs were detecte

The formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and chlorobenzenes (PCBzs) in the combustion process was studied where the chlorine level and source were varied in an artificial waste. Different levels of organic ch
