AB  - A reconnaissance study was undertaken to determine potential contaminant 
      exposures to children through soil from elementary school playgrounds. Soil 
      samples were collected from areas along the Texas-Mexico border, inland areas 
      (soils from elementary school yards in cities/towns within the state of Texas), 
      and three National Parks (one on the border, one in Tennessee, and one in 
      Washington). The present study focused on organochlorine (OC) pesticides as the 
      potential contaminants of concern because of their historical (and possibly 
      current) use, and their importance as persistent organic pollutants (POPs). DDE 
      and heptachlor were the most frequently detected OCs (69 and 63%, respectively), 
      although heptachlor concentrations in soil never exceeded 5 ppb. Relatively 
      higher concentrations of DDE were observed in agricultural areas along the border 
      (50-60 ppb in soils from McAllen, Palmview, and San Benito) than in other soils. 
      However, a school yard in Lubbock, TX had the highest OC concentration observed 
      (70 ppb dieldrin). These results may be due to historical agriculture activity 
      prior to the banning of OC pesticides such as DDT in the early 1970s, as well as 
      the more recent use of DDT in Central and South America for malaria control.
