The article discusses how soil in China is contaminated with heavy metals, which can be harmful. Researchers are studying bioremediation as a way to clean up this pollution. Bioremediation uses living organisms like plants, microbes, and animals to remove the heavy metals from the soil. While bioremediation shows promise, it is still being researched and has some limitations in large-scale applications. Different methods like phytoremediation, micro-remediation, and animal remediation are being explored. Overall, bioremediation has both advantages and disadvantages in treating soil pollution, and more research is needed to improve its effectiveness.
