Is there still DDT in the soil, or in people who were alive before it was banned?

    There may still be some DDT in the soils from where it was applied. The amount of time before half an application of DDT is degraded is between 2 and 15 years. Half of what remains is degraded in another 2-15 years. Assuming this is at the high end, about 1/4 of what was last applied in the 1970s would be still in the soil.
