the very fact that she still is alive to tell the story negates the safety issue (i imagine the concerns are trumpeted for decades toward her, not new thing)
she's probably healthier than those safety-conscious people who buy groceries at wal-mart
by volume, plants are consist of carbon, oxygen, and nitrogen, phospate, potassium; thus major elements. they do take CO2 from air pollution to grow. motor oil, if it ever breaks down, probably will just supply C and O. lead is not even a trace element, average plants probably don't take Pb and if they do, probably extremely minute, like 0.0000001% (# pulled out of my ass)
maybe just washing it with baking soda and rinsing it with running water is sufficient, probably overkill -- don't worry much about plants, they are normally safe, that's why you rarely read news about people got killed by eating plants.
i'm starting urban gardening too (i played with aquascape before) ... it will be interesting
- fatdog789 17y agoPlants absorb water, and the water may have chemical contamination. It's exactly the same way that it works in animals. Different plants are affected to different degrees.
- easp 17y agoLots of 'probablys.' You should probably do more reading and less writing. There are elevated lead levels around "civilization" due to human activity. (Lead paint, tetra-ethyl lead in gasoline, pesticides, etc). Food crops vary in the degree to which they accumulate lead, but they do. In general, the skin of roots and tubers have the higest levels and fruits the lowest. Keep in mind though, stems and leaves can have higher levels, particularly since various members of the mustard family (which includes broccoli, cauliflower, brussel sprouts, etc) are deliberately used for phytoremediation of lead.
- hs 17y agofine, can you point me the cases when someone die due to lead poisoning from eating plants alone? my point is that the amount of Pb is minimal in plant, esp if you wash&clean it. you probably will get more Pb from eating pesticides, inhaling gasoline or licking the paints the more reading you do, the more you will be asking questions. some of conclusions i had in past years are now broken. i keep learning stuff -- so really, i don't have absolute knowledge about anything ... but it's okay
