TI  - Chlordane uptake and its translocation in food crops.
PG  - 1909-15
AB  - Chlordane is a member of the persistent organic pollutants (POPs), a group of 
      chemicals characterized by extremely long residence in the environment after 
      application. Technical chlordane, composed of a large number of components, is a 
      synthetic organochlorine substance that was used primarily as an insecticide. 
      Uptake by root crops of persistent soil residues of chlordane was noted early in 
      the chronology of the material. The present report is the first comprehensive 
      study of the uptake of weathered soil residues of chlordane and its translocation 
      throughout the tissues of food crops under both greenhouse and field conditions. 
      The data show that for all 12 crops chlordane is not limited to root tissue but 
      is translocated from the root to some of the aerial tissues. Chlordane 
      accumulation in edible aerial tissue appears to be dependent on plant physiology. 
      As expected, chlordane was detected in the edible root tissue of the three root 
      crops examined, carrots, beets, and potatoes. In the remaining crops chlordane 
      was detected in the edible aerial tissue of spinach, lettuce, dandelion, and 
      zucchini, whereas it was not detected in edible aerial tissue of tomatoes, 
      peppers, and corn; trace amounts of chlordane were detected in the edible aerial 
      tissue of bush beans and eggplant. Under the conditions of the field trial the 
      data indicate that for weathered chlordane residues, the soil-to-plant uptake 
      route dominates over the air-to-plant uptake route. This is the case even when 
      the soil concentration of the recalcitrant, weathered residues, for which 
      volatilization is expected to be minimal, is as high as it would be directly 
      following application. Greenhouse trials confirm this observation for zucchini, a 
      member of the Cucurbitaceae family, which bioaccumulates weathered chlordane very 
      efficiently in its edible fruits.
