Since 2003, hazardous amounts of lead have been documented in backyard and community gardens in New York as well as in Baltimore, Boston, Chicago, Detroit, Indianapolis, Los Angeles, Minneapolis, New Orleans, Philadelphia and Washington. Lead-laden soil has been found not only in inner city neighborhoods but also suburban areas.
Mainstream media -- and their big business backers -- do not like you growing your own food. They will do anything they can to scare you off it. Notice how they hide the actual, practical advice in the second page, so the laziest readers will simply conclude that home gardens are dangerous.
They could have just as easily written a story called, "Clever gardeners find ways to deal with lead in their soil." But, nope, big food™ wouldn't like that.
Does lead in the soil get into plants?
Yes. We had the same problem at our old place, tested the soil and the lead content was through the roof. So we build raised beds, brought in new soil and presto, the garden is good to go.Quote:

Why not? If you drive a short distance to Leamington you will see that everything is grown in greenhouses.
This is exactly what my folks did in the D, and what my church is doing up in the Ann Arbor area. When I had my first independent garden, the first thing my Grandma said was "don't use the soil that's there -- bring your own." So everything's in pots, planters, and raised beds.Quote:

Everywhere. Look around.Quote:

so, from the info Im seeing here, a fast food company could argue that the real fattening of Urban America is really just the added weight of accumulated lead from home grown veggies.
Bad, evil urban gardeners .... eat more fried synthetic chicken.
Hmm. I guess I just assumed that most of the main community gardens are transporting in their own topsoil and compost. If they aren't, it's a problem.Quote:

This would never have occurred to me.Quote:

How does one go about disposing of one's hazardous, lead-laden spinach as toxic waste?
There are a couple of those alphabet things we are all lousy with around here as well, PBBs and PCBs. One is that fire retardant they accidentally fed to the poor cows in the 70s, and the other has to do with electrical transformers. Do they test for those? Are they picked up by plants?
It seems most plants don't pick up heavy metals, and the biggest danger is contact with the soil, per this article and others I have read:
Luckily, most vegetable and fruit crops don’t absorb high levels of lead into themselves even if planted in areas with lead contamination. “Each plant has various degrees of absorbance,” says Jouraeva. “But lead is usually not transmitted through shoots.” The most danger with regard to lead poisoning comes instead through direct ingestion of contaminated soil. This usually happens when children play in toxic soil and get it into their mouths or when people eat contaminated soil found on the exterior of unwashed produce.

Wouldnt worry about the heavy metals in Detroits soils. Go anywhere in Europe. If you dig you will find thousands of years of heavy metals.
No one complains that their French wine or cheese tastes like lead :)
