Persistent Pesticides

Abstract Medicinal plants may carry residuals of environmentally persistent pesticides or assimilate heavy metals in varying degrees. Several factors may influence contaminant accumulation, including species, level and duration of contaminant exposure, and topography. As part of a program for assessment of the quality of herbal medicines, we have analyzed 21 over-the-counter ginseng (Panax ginseng) products in various dosage forms. Chromium, mercury, and arsenic were undetectable above their limits of detection in both liquid and solid samples; while cadmium, lead, and nickel were present in the majority of samples. The chlorinated pesticide levels varied widely. In most samples, the total concentration of pesticides was below 100 ppb; while in 5 samples the total concentration exceeded 100 ppb.

Causality Chain

An integrated approach concerning the causality chain of emission, distribution and effects of toxicants was chosen to analyze the influence of pollution and the impact of historical and future measures in the Rhine basin. All major sources have been quantified and the distribution of nutrients and toxicants is determined by means of a dynamic model. A contaminant accumulation model is linked to this water quality model in order to assess the ecological effects of the compounds in specific areas. This modelling framework is used to analyze effects of cadmium on the foodweb found in Rhine sedimentation areas. Model predictions show that No Observed Effect Concentration (NOEC) levels for cadmium in algae and small molluscs are not exceeded.
