Same thing in south italy the camorra dump waste from almost 40 y in the 90s a casalesi clan rat said everything but the files was secretated I dont know why and this rat died falling by the roof that was reparing even if was under protection and was almost 70 and sick.
My uncle have garden with a Orange and a Lemon trees. One day call me and show a very big orange the doubled of a normal Orange then he cut it and inside was similar to the Lemon and the taste was a mix better the 2 fruits. We joke saying that was a hybrid due he live in the terre dei fuochi (fire lands). He at the end cut the 2 trees because find other fruit like that.
