In this study, scrap tires and a type of microorganism called Pseudomonas sp. were used together to remove harmful chemicals like BTEX, TCE, and cis-DCE from water. The researchers found that these chemicals stick well to the tires and are removed more easily within a day. Toluene stuck the best, followed by benzene, m,p-xylene, o-xylene, ethylbenzene, TCE, and finally, cis-DCE. When the microorganisms were attached to the tires, they did an even better job of removing the chemicals. After five days, 95% of BTEX was removed, and 75% of TCE and 60% of cis-DCE were also removed. This study shows that using scrap tires and microorganisms together can help clean up these harmful chemicals from water effectively.
