Abstract
|
Water is an exceptionally essential source for the presence of life on the earth. The
water quality has seriously affected because of the overgrowth of the population, human
activities, and unskilled utilization of natural water resources [1]. Constructed wetland (CW)
systems are used worldwide for removing pollutants from several types of wastewater. Their
construction is relatively simple and their operational and maintenance costs are lower than
conventional wastewater treatment technologies [2]. Plant metabolism can help to remediate
or clean up contaminated sites. The pollutants enter the plant primarily via the roots, which
contains many detoxifying mechanisms, provides surface area for adsorption and
accumulation of water and nutrients that promote growth. These pollutants when absorbed by
the plant, may be stored in the roots, stems, or leaves; changed into less harmful chemicals
within the plant; or changed into gases that are released into the air as the plant transpires [3].
In this study, plants were selected and exposed to contaminated water. After a specified time,
the output water was tested and the percentage of contaminated material was calculated. Then
different parts of the plant were tested.
