Looking for reasons NOT to collect urban rubble for an experimental substrate. Northeastern US.
The idea behind is to observe and tinker with urban succession in my back yard. I am located in a city. My garden is containers on a concrete slab.
I realize there is some level of toxicity to whatever I would be collecting. That’s part of the interest. But I don’t want to poison any of the creatures I have so far attracted. I figure if all the material would be hyper local, the damage is already done (?) I would select from areas without evidence of spraying.
I’m looking for the scientists and skeptics among you to guide me. What are the main contaminants of concern? Why shouldn’t I do this?
Photos are just examples of material described
