Paint samples for Round 21 were pepared from paint chips collected from a variety of sites in North Carolina and Ohio, including a school, a hospital, and a warehouse. The chips were ground to a mazimum particle size of 120 micrometers (um). Soil samples came from driplines around North Carolina residences. Soil samples were dried and then sterilized by heating the soil to 325 degrees F for a minimum of 2 hours, and finally sieved to a maximum particle size of 150 um. Round 21 dust wipes were prepared from dust collected from households in North Carolina and Milwaukee, WI. Following sterilization by gamma-irradiation, the household and post-abatement dust was sieved to 150 um and gravimetrically loaded on a premoistened PaceWipe (tm), which meets ASTM E 1792 specifications. The loaded wipes were stored under refrigeration until shipment as an antimicrobial measure. Also, it was recommended that dust wipe samples be refrigerated until the laboratory analyses were performed, as an additional precaution to reduce/prevent the growth of mold. A total of 375 laboratories was enrolled for Round 21 of the ELPAT Program, with 353 labortories (94% submitting results.
