I wonder, if you grow a food plant in certain conditions (soil, polluted air...) does the resulting food the plant bears become toxic?

@onfy plants can accumulate toxins found in the environment. There are places where rice has a measurable arsenic content because they basically filter it out of the ground. It's sometimes even used to "clean" soil and make it safe to grow things on again

@noiob ah, I thought I read about a plant being used for crop rotation, it was rice!

@onfy really? rice needs to grow in flooded plains, that sounds like a pain to rotate with other crops

@onfy I guess it's possible with some careful water management
