They used to use arsenic and arsenic derivatives as a agricultural pesticide/insecticide for well over half a century.
Lets say for 40 years of inorganic arsenic derivatives were used in the same fields owned by some farmer. Add another 15 year of less-harmful-but-still-harmful organic* arsenic derivatives were used afterwards. How much would 50-60 years of continued use impact the soil? Would it accumulate given arsenic is a base compound and doesn't break down or would it dilute and get dispersed at a fast enough rate?
*no not that type of organic, the scientific chemical meaning
