My landlord hired guys to take the aluminum siding off my duplex, and they've killed several vegetables, and injured many of my tomato plants. But the more insidious issue is all of this chipped paint, rusted metal pieces, and other debris that's falling down and mixing with the dirt. I have no idea when this place was last painted, so I have no way of knowing if the paint had lead, or what. What's the worst that can happen with paint chips near the roots of my plants? Should I be worried to the point of not eating the fruit?
