Lead in soil is bound to minerals in the soil. The lemon juice is used to extract the lead from those minerals. The extract can then be tested using LeadCheck Swabs. Hybrivet manufacture a Lead In Soil Kit (LeadCheck Soil) that uses a much stronger acid for the extraction step. Lemon Juice extraction will work fine on soils with high lead content (>1000ppm). LeadCheck Soil will test down to the residential standard set by the EPA (>400ppm).
