390 mg/kg of lead was measured from the soil of the play ground of a nursery school in Yokohama.
Because arsenic and lead were found more than the safety limit of 150 mg/kg in the parking lot located next to the nursery school on 3/23, Yokohama city government was analyzing the soil of the nursery school.
It has been prohibited to use the play ground since 3/23, none of the health problem has been reported so far.
