The significant role of plants in both cycling of trace elements and contaminating the food chain has been well illustrated for various ecosystems.  Plants can accumulate trace elements, especially heavy metals, in or on their tissues due to their great ability to adapt to variable chemical properties of the environment, thus plants are intermediate reservoirs through which trace elements from soils, and partly from waters and air, move to man and animals. Leafy vegetables are regarded as group whose leaves and stems are eaten as vegetables.They also have an abundance of vitamins and minerals within them. The primary minerals present in green vegetables are magnesium, iron, calcium, potassium, vitamins C, E and K amongst others. Studies have shown that leafy vegetables have greater potential of accumulating heavy metals in their edible parts than grain or fruit crops as fruits and seeds have low transpiration rates.

SEED DRESSING WITH PGA The water solution of PGA has better moisture-holding and releasing ability and is more effective in fighting a drought and keeping a full stand of seedings. Mixing PGA,with seeds dressing　 and using water saturated PGA,as antistaling material,will increase the germination percentage of the seeds,and prolonge the freshness-keeping period of cutting flower. PGA can increase photosynthesis, increase fruit pigment accumulation,   make crops bright in color. In soil water swellable ventilation without being dissolved, so that the seeds germinate properly, so the slow release of pesticides and fertilizers, having to kill soil pests, prevent seed germs, improve seed germination rate, reduce the amount of seed use, improved crop varieties. Seed close to the seed, the drug concentration, high efficiency, and thus save more than spray, soil treatment method of drug administration, labor, save species.
