The single factor pollution index assessment showed that the pear and mango Pb has light pollution. However, other elements could be regarded as clean levels. The comprehensive pollution index method evaluation, according to the results of apple and banana as the safe level; Peach, pear, mango and pitaya were at warning line level. Adult and children single heavy metals health risk index was less than 1, the danger of heavy mental on people was not obvious.
