thesis importance of article
Thesis & Importance of Article
  • Percolation systems or wetlands contain plant species that are capable of phtyoremediating stormwater contaminated with heavy metals.
  • The most toxic metals commonly found in stormwater were used in this study, including cadmium, copper, zinc, and lead.
important terms
Important Terms
  • Stormwater= is where impervious surfaces, such as roads and roofs, drain rain and snow melt water. It is mostly contaminated by organic pollutants, oil, and heavy metals,
  • Phytoremediation= is a process where contamination is either stabilized, eliminated, removed, or destroyed by plants.
background
Background
  • Heavy metal concentrations are usually greater in stormwater than in naturally occurring waters.
  • Wetland/percolation area treatment of stormwater is preferable over other methods.
  • Contaminated areas contain a variety of plant species with differing capabilities for heavy metal remediation.
background continued
Background Continued
  • Terrestrial and emergent plant species exist in percolation areas.
  • Free-floating, submerged, and emergent plants occur in wetlands.
  • The most effective metal remediating plants were needed for this study.
  • To determine this, a metal concentration analysis was done on the most common plants found in the study area.
methods field study
Methods- Field Study
  • Three sampling areas were used for the field experiment, labeled Areas 1, 2, and 3.
  • They were all located 7-15 km south of Stockholm, Sweden.
  • Plants and soil samples were taken from all 3 areas on the same day.
  • Plant samples were collected from the most abundant species in the 3 areas, such as P. natans (submersed), L. gibba (free-floating), A. plantago-aquatica (emergent), and F. ulmaria (terrestrial).
  • Plant samples were divided into root and shoot sections.
  • 12 species total were used in this study.
methods controlled study
Methods- Controlled Study
  • The plant species F. ulmaria, P. natans, and A. plantago-aquatica were used in this experiment.
  • A heavy metal mixture was added to half of the plant samples, the others were left as controls.
  • All plants were cleaned with water.
  • A flame absorption spectrophotometer determined the metal concentrations.
  • ANOVA was used to statistically analyze the data.
results
Results
  • Zinc concentrations in plants were between 16-451µg 1/g DW.
  • Copper concentrations in plants were between 2.7-94 µg 1/g DW
  • Cadmium concentrations in plants were between 04-48 µg -1 DW
  • Lead concentrations in plants were between 30-26 µg 1/g DW
discussion
Discussion
  • The submersed plant species removed more metal contaminants (e.g. P. natans).
  • The three areas showed that different plant species contain various levels of metal concentrations.
  • The plants showed an ability to intake more contaminants at higher metal concentration periods. (e.g. heavy rains).
  • The majority of the terrestrial and aquatic plants used in this study were effective at removing heavy metal contamination from stormwater.
critique
Critique
  • Good and important study.
  • Needed more plant species in the controlled study.
  • Lack of data from other types of stormwater contamination studies.
  • Plant and soil collection occurred on only 1 day in both the field and controlled experiments.
