A bit of fun for a Friday!!!!

A harvest spider walks through a field to his nest with 300 nanograms of xtrakill pesticide on each of his feet. The Molecular weight of the pesticide is 500 nanograms, the spider dies on reaching his nest located below ground. the nest is 10 cc, what would be the concentration of pesticide within the nest? If the STEL was 4 ppm would the other members of the spider community living in the nest be in danger?

From what I know of spiders, the answer would be that the others would probably consume the corpse, so there might be a problem with ingestion!
