While the pre-measured "pods" for laundry and dishwasher detergents may be convenient, they are wrapped in a plastic called polyvinyl alcohol, or PVOH; it's a plastic that is designed to "dissolve" in contact with water, but rather than fully dissolving, it goes into the waterway and becomes a microplastic. The best course is to stick with old-fashioned detergents in powdered form for laundry or look for tablets that aren't wrapped in plastic for your dishwasher.
