I don't know about the article as such. But just one detail, artillery grenades do not contain toxics. Sure, each one contains a kind of watch or sensor, which may contain things you can find in every other watch and which are not recommended for eating. The metal parts are embedded in shooting powder and cotton and are not toxic. I mean they were produced in order to destroy everything in a diameter of 10 meters, not on impact but by exploding a few meters above the ground.
