Reduction of hydrocarbon pollutants by hyacinth plants (Eichhornia crassipes)

Background: The application of phytoremediation by utilizing plants has been used to control oil pollution in waters. One the that can act as a phytoremediator is hyacinth because this plant reduce various pollutants including petroleum hydrocarbons. This study aims reduction ability hydrocarbons at different concentrations improving water quality. Methods: consisted one treatment (petroleum hydrocarbon) consisting five factors with three replicates. The treatments 10 ppm (E1), 30 (E2), 50 (E3), 70 (E4), 90 (E5), and (E0) without aquatic controls. were observed daily measured from first day (D-1), seventh (D-7), 14th (D-14). quality each was also measured, such temperature, pH, dissolved oxygen. Results: results showed able hydrocarbon terms total (TPH) 79% while it only between 17–27% naturally hyacinth. TPH line decrease chlorophyll leaves hyacinths, followed increase oxygen media. Conclusions: In conclusion, hyacinths they improve well.
