Abstract
Plants have various kinds of functions. One of them is a purifying function to
gaseous contaminants including carbon dioxide. It is a noticeable function from
the standpoint of protection of the global environment. Plants can purify not only
carbon dioxide but also nitrogen oxide and sulfur oxide, and the chemicals are
used as a source of energy after having been broken down in the plants. In
addition, plants put out a bioelectric potential which changes depending on the
environment and growing conditions. In this study, the relationship between the
potential and purification capability of a plant is examined using an LED lighting
system. Broccoli is adopted as a subjective plant and the experiment is carried
out with five kinds of LED light frequencies including darkness. The summation
value is adopted as the potential value, namely the total amount of the bioelectric
potential for a minute (vm1). As a result, the capability increases and the potential
also becomes greater in blue light. A positive correlation is recognized in the
relationship between the potential and the capability. A specific gaseous
chemical could be purified in a particular light-frequency by applying the results
of this study.
Keywords: plant bioelectric potential, air pollution, purification capability.
