Purpose of Project

I have just gained access to this site. In 1968, chlordane was applied to a known area. Residual levels are around 5ppm but because of the urban location, 1ppm total DDX (DDT,DDE,DDD) and a number of PAHs are also present. I grew several cutlivars of zucchini and squash, as well as hybridized and backcrossed individuals of each. Zucchini has been shown to accumulate certain weathered persistent organic pollutants whereas squash does not. No results are yet available for this first year of the trial.
