I'm concern about the amount of PCB that can be introduced
into plants grown in and around our backyard. I've been
consuming these plants for many years but now changing my
habits. Instead, I'm growing and eating herbs. Is it safe to
eat vegetables or herbs grown in our backyard under to an
electrical power lines?

Thanks

How do you know pcbs are in your backyard? Those associated
with power lines were contained in transformers, if some years
ago one of these leaked or somehow broken then it might be
possible some is there.

Forget about the power lines. Nothing to worry about there.

PCBs are everywhere in the world, in all environments, but at
extremely low concentrations. The only real risk comes from
biomagnification, the effect of eating high off the food
chain. As your garden produce puts you at the very lowest
level of the food chain, the risk is minimal to nonexistent.
If it still bothers you, there is one thing you can
do....increase the organics in the soil. Compost, manure, that
sort of thing. PCBs and dioxins and the like will tend to
partition into any organic substrate, so having high soil
organics gives the PCBs a sink, an alternate to being
partitioned into the plants you want to eat.
