Danielle Stevenson ... has been pioneering a nature-based technique for restoring contaminated land, using fungi and native plants to break down toxins like petroleum, plastics, and pesticides into less toxic chemicals. The usual way of dealing with tainted soil is to dig it up and cart it off to distant landfills. In a recent pilot project funded by the city of Los Angeles, Stevenson ... working with a team of UC Riverside students and other volunteers, significantly reduced petrochemical pollutants and heavy metals at an abandoned railyard and other industrial sites in Los Angeles. Stevenson says she believes her bioremediation methods can be scaled up to clean polluted landscapes worldwide. Decomposer fungi can degrade petrochemicals the same way they would break down a dead tree," [said Stevenson]. "And in doing so, they reduce the toxicity of these petrochemicals and create soil that no longer has these contaminants or has much reduced concentrations of it. They can also eat plastic and other things made out of oil. People who live in a place impacted by pollution need to have a say in how their neighborhood is being cleaned up. We need to empower them with the tools to do this. That's why along with doing these studies and pilot projects, I've been running workforce development programs. Potentially, they could bring economic opportunities and benefits to the community in addition to cleaning up the contaminated site."
