Lets see, the fine particles of soot you get from wood or coal fires aren't going to get into the plant, or are the fine copper particles from people's brake pads. Nor will carbon monoxide, nitrous oxide, or sulfer dioxide. Most sorts of pollution that can make you sick from eating vegtables exposed to it will kill you super dead if you breath it in. One obvious exception is lead which can accumulate in soil over the long term so make sure you don't get your urban garden soil from an abandoned lot which hasn't been tested for lead levels. Also some radioactive isotopes of things like iodine can be concentrated in plants but the ones that come to mind as doing that, like iodine-131, have half lives on the order of days to weeks so that's mostly just a concern if there's been a recent reactor meltdown or nuclear attack in your area.
- baud147258 7y ago> the fine particles of soot you get from wood or coal fires I'm pretty both coal and wood fires are banned in Paris. For wood fire, I think it's fairly recent (one or two years ago) and it's an application of a directive from the EU.
- liotier 7y agoOpen fires are banned, but the automobile particulate mix (tire & brake wear + exhaust) and fuel-powered heating do generate a fine soot I find on my bicycle, though nowhere near as much as 30 years ago. A quick wash and my Paris balcony tomatoes are safe and delicious !
- sgc 7y agoHowever I remember seeing studies by Italian television which showed that fruit markets in cities had very high levels of pollutants that stuck to their surfaces. This was related to how busy the road in front of the fruit market was, but will be compounded by the long grow period. So the produce will need to be cleaned very well.
- Wowfunhappy 7y agoAren't you always supposed to wash fruit/vegetables before eating anyway?
- sgc 7y agoThe issue is how much actually comes off when you wash them. There were vegetable rinsing aids on the market for a short time. Some compounds like to stay put.
