Abstract
This is a comparative study of a living plant (Hedera herix L.) and similar shape imitation greens which have the adsorption amount per cm2 (-μg/cm2) during extended times in the outdoor environment. In addition, we considered the plant and these materials, characteristics and advantages. It was found from the result that NO3- -μg/cm2 were larger than SO42－ -μg/cm2 in all measurement terms. In a similar, Warm seasons were larger than Cool seasons, too. Furthermore, NO3- -μg/cm2 degrees were Polyester imitation green (PL) ＞ Polyethylene imitation green (PE) ＞ Polyester -Polyvinyl chloride coating imitation green (PL-PVC) ＞ Hedera. It's as the Hedera and weather resistance enhanced products (PL-PVC) had resulted in a decreased. On the other hand, SO42－ -μg/cm2 were not obvious differences Warm and Cool seasons. However, it became clear that the Hedera was second largest during Cool seasons.
