Pounds weight is a terrible way to measure toxins. This report is basically meaningless, because it lumps together toxins with vastly different risks. Eg. sodium carbonate is included, which is just common washing soda. I wouldn't eat it but the risk is easily manageable. Compare with, eg. dimethylmercury, which is scary even at parts per billion concentration. An actually useful measurement would take into account both potency and persistence of toxins.
