Phytoremediation Of Lead Contaminants

Sunday, March 18, 2012

The March 12, 2012 edition of, the online relative to the New Jersey daily newspaper The Record, includes a fascinating article titled Exotic grass could help clean lead from soil that describes vanguard research being done at Montclair State University using vetiver for phytoremediation of soils that are contaminated with lead residues.

We all forget that lead from old paint chips (prior to 1978) and leaded gasoline (prior to the 1990s) are still around in our environment, and New Jersey still reported more than 1300 cases of lead poisoning among children in 2010. Much research remains to be done, but preliminary tests of vetiver's ability to remove contaminants from soil are very encouraging and validate what many of us vetiver practitioners have been saying for years.

Vetiver's survival during the harsh winters of the northern states remains a high hurdle but the southern states my find this a viable solution. The development of a cold-tolerant strain of vetiver has been the holy grail of vetiver growers for many years. Perhaps research such as this will encourage geneticists to develop such a plant.
