Safe Food From Contaminated Soil? Biodynamic Agricultural Method Shows Successful Field Research

摘要

Many farmers and consumers are unaware that persistent organochlorine pesticides (POPs), such as DDT, are active in our soils and still a health issue many years after their sale in the United States was banned. The situation remains critical becausemost agricultural ground has been exposed to POPs at some time, cropping and treatment histories are notoriously inaccurate, and there is a long breakdown time for toxins in untreated soil - about eighty years for DDT. In addition, POPs continue to be released into the environment, sometimes accidentally by U.S. producers or transported by weather or in produce from countries where pesticides are used without restriction.
