ABSTRACT

A study was carried out on the level of heavy metals, total coliform and benzo(a)pyrene thatmay be introduced through by-product fertilizers or air pollution to turfgrass in naturalturfgrass playground in elementary schools around the western coast and eastern mountainareas in Jeollabuk-do, Korea. The level of heavy metals found in turfgrass was in the order ofCu > Zn > Pb > Cd. The majority of heavy metals was found in the roots. It is presumed that theabsorption of some air pollutants and by-product fertilizers or chemical fertilizers. The level ofbenzo(a)pyrene showed an average of 0.05ng/g with a range between 0.02 to 0.08ng/g in theleaves. In the meantime, none was detected in the stems, while the average for roots was0.02ng/g with a range between 0.01 and 0.03ng/g. The level detected is that found backgroundlevel, however, benzo(a)pyrene can be introduced partly from the unstable combustion of fossilfuel or through vehicle emissions. Total coliform distributed in grass showed an average of12MPN/100ml with a range between 2 and 36MPN/100 ml. The density of total coliformdisplayed no regional predominance. However, in some urban areas, the density was slightlyhigher. The feces of pets or by-product fertilizers may have contributed to the input ofpathogenic micro-organism. Yet the level was found to be negligible.
