This article discusses how Plant Growth Promoting Rhizobacteria (PGPR) can help clean up cadmium and chromium from soil. The researchers looked at different methods like phytoextraction, phytostabilization, and phytovolatilization. They also talked about what factors can affect how well the cleanup works. The researchers collected examples from other studies to see how effective PGPR can be for cleaning up cadmium and chromium.
