Cadmium, lead and zinc are released into tiny particles as dust from rubber tires on road surface. These small size particles allow these toxic metals to raise on the wind to be inhaled, or transported onto top soil or edible plants. Cadmium compounds are used as stabilizers in PVC products, color pigments, several alloys and now most commonly in rechargeable nickel-cadmium batteries. Metallic cadmium mostly used as an anticorrosion agent. Cadmium is present also as a pollutant in phosphate fertilizers.
