Phytoremediation: Colorimetric and Bio-chamber Studies of Air and Water Contaminants Removal Capacity of Various Plants

CSEF · 2014 Environmental Science

Yu Xia · Clovis West High School, Fresno, Fresno County

Overview

Objectives/Goals The objective is to determine the possibility of using easy and accessible materials along with plants to remove air and water contaminants. Methods/Materials In Phase I of the experiment, polytrichum (moss) and equisetum (horsetail)#s ability to absorb copper in water is tested. In Phase II, a primitive bio-chamber is constructed to test out the possibility of using triticum (wheat grass) as an air-filter. Results In Phase I, results showed that the intaking of water in plant metabolism absorbed copper in water as well. As for Phase II, while quantitative data wasn#t able to be obtained, the qualitative comparison of the testing materials between the control and the experimental group showed that tritium did have some air-filtration effect. Conclusions/Discussion The experiment successfully proved that extremely accessible plants could be used as a way to remediate air and water pollution. This experiment also points to a new possibility of using bio-filter made from readily available plants to serve as a pollution control technique.

Summary statement

This project looks at the possibility of using easy and accessible materials along with plants to remove air and water contaminants.
