Is it safe to grow food in urban soils?
The perception is that agricultural soils are pristine, while urban soils are contaminated.
What is the reality?
Agricultural soils are highly managed soils. They undergo lots of soil testing, and receive irrigation, annual applications of fertilizers, and often herbicide treatments.
Urban soils, on the other hand, suffer more from neglect than from contamination. You can find contaminated soils in urban areas, but they are generally the exception rather than the rule.
