Abstract |
Alkali polyethylene glycolate (APEG) was field tested at Shenandoah Stables in Moscow Mills, Missouri, to evaluate the chemical's potential to dechlorinate 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) under field conditions. An experimental design employing a Latin square was used to compare five levels of treatments. The treatments were designated: (1) APEG-treated and covered, (2) APEG-treated and uncovered, (3) not treated and covered, (4) not treated and uncovered, and (5) methoxpolyethylene glycol (MPEG) control and uncovered. In addition to the arena site, two sections of bleachers were also treated with APEG to determine the chemical's ability to decontaminate dust-covered surfaces. It was determined that there was not a statistical difference between those plots treated with APEG and those treated with the MPEG control. Soil moisture was determined to be on the order of 18 to 21 percent by water weight. APEG has been determined to be extremely hygroscopic. The property resulted in its deactivation and prevented significant TCDD reduction in the Latin square experiment. The bleachers test showed approximately a 32-percent and a 16-percent reduction in 2,3,7,8-TCDD in the final dust samples after a single application of APEG. |
