Effect of residual pieces of degradable PE films on the heavy metal contents in the crops

Effect of residual pieces of degradable PE films on the heavy metal contents in the crops

25th National agricultural plastics congress Proceedings of a conference held in Lexington, KY, USA, 23-27 September, 1994: 168-173

Heavy metals may be added to plastic mulching materials as heat or light stabilizers, or photosensitizers. The amounts of Fe, Pb, Ni, Cd, Cr and other heavy metals accumulated in watermelon and cantaloupe fruits, grown on plots covered with degradable polyethylene mulches in southern Taiwan were not significantly different from those accumulated by controls (ordinary polyethylene mulch).
