ur environment. Micro-organisms, for example, are important to keep in the soil. We don't want to kill them or remove the beneficial minerals and metals. Our advanced solution keeps all these factors in mind," he says.

The special compound developed by the Tel Aviv University team relies on advanced chemical architecture: they've created molecular compounds with complex and highly specific functions. As well as being able to recognize and bind to certain metals such as cadmium, the compounds are also non-toxic and biodegradable.

Current solutions for cleaning the soil are very time-consuming, expensive and not completely effective. They strip the soil of all its basic compounds, leaving behind dead and useless sand. They also leave behind their own toxic byproducts and do not biodegrade. "These solutions solve one problem, but create others," says Dr. Gozin, who also works on research projects for the U.S. Department of Defense, and the U.S. Air Force.

Other Applications

The new Tel Aviv University solution will give polluted soil a new lease on life and may affect business as well. Properties close to industrial parks are especially at risk and the value of that real estate remains low.

Technically-speaking, the solution could also be applied in the mining industry, to help mineralogists pull certain desired chemicals from the soil, like gold or the rare metals used in the high-tech industry.

The Tel Aviv University research is funded by the Israeli Science Foundation.
