Toxic metals in root vegetables -- KARACHI: Vegetables being grown and sold in certain parts of the city contain
very high levels of toxic metal content — lead, iron, copper and cadmium — posing a serious health risk to consumers,

Class B sludge is widely used as a "fertilizer" for corn and soybeans. Also, the US EPA and waste
industry recommend the use of Class A sludge biosolids "compost" in home vegetable gardens. Thus,
sludge used on food has the potential to weaken our immune systems and ability to resist disease.
2007 "Plant uptake was evaluated in a greenhouse study involving three food crops: corn, lettuce, and
potato. Plants were grown on soil modified with liquid hog manure containing Sulfamethazine, a commonly
used veterinary antibiotic. This antibiotic was taken up by all three crops. Concentrations of antibiotics
were found in the plant leaves. Concentrations in plant tissue also increased as the amount of antibiotics
present in the manure increased. It also diffused into potato tubers, which suggests that root crops, such
as potatoes, carrots, and radishes, that directly come in contact with soil may be particularly vulnerable to
