How quickly and easily is lead absorbed into plants?
In particular, we’ve got some wild garlic growing right behind our house. The bulbs make a tasty garlic paste. However, my wife pointed out the disturbing fact that there’s a lot of paint chips in the soil that have flaked off the house. Old paint chips. Eighty years of old paint chips. So how easily does the lead leach out of the paint and into the soil? And how much of it gets taken up by the garlic bulb?
And, to make the question more general, would the answer be different if we were talking about other root crops (say, taters) versus berries (say, tomatoes or raspberries) versus leaf or flower crops (say, lettuce ans basil and broccoli)?
