The directive recommends that soil lead levels less than 400 mgkg are generally safe for residential use. Above that level the document suggests collecting data and modeling blood-lead levels with the IEUBK model. For the purposes of screening therefore 400 mgkg is recommended for residential soils.
For water we suggest 15 µgL the EPA Action Level in water and for air the. Nickel is a transition element extensively distributed in the environment air water and soil. It may derive from natural sources and anthropogenic activity.
