It probably depends on the area, but probably non-welfare related impact is going to vary by industry significantly. E.g. I imagine that insecticide use has fairly substantial environmental impacts, but that residential insecticides do not. I haven’t looked into this at all, but I’d guess there are many ways in which these industries are bad and also good (they all exist because they provide some useful benefit) besides the welfare implications.
