- In the period 1984–1990 the following vegetables were grown: red beet, carrot and parsley in four allotment gardens of Płock city (Central Poland), situated near the refinery and petrochemical works. Cadmium, lead, copper, chromium, zinc and manganese concentrations were determined in the leaves and roots of vegetables. The heavy metal accumulation in the soil, dustfall (measure of air pollution), and ground water was determined. The quality of the vegetable yield, notably of the leaves, was low. This was mainly due to the excessive chromium and cadmium content in the leaves. Accumulation of heavy metals was relatively low in the soil, rather high in the ground water and variable in the dust.
