Abstract
Brownfields are becoming serious problems now. In soil contamination countermeasures law, the soil content standard is calculated by using the amount of soil ingestion each day. This amount is set at 200mg/day in the case of children and 100mg/day adult. The amount of soil particulate was able to be estimated by wiping soil particulate on hands and measuring the amount of Al in some stuff with which wipe hands. The amount of the adhesion of soil on children's hands examined by wiping their hands after they played outside was 50mg, and the estimated value of ingestion of soil particulate from the atmosphere was 0.5mg. If these values are equal to ingestion of soil particulate, they were about a quarter of the amount of soil ingestion each day. This conclusion shows the validity of the amount of soil ingestion used in environmental quality standards for soil pollution.
