Does PVC leach anything into the water, especially when exposed to full sunlight/UV?

Apparently, there are several kinds of PVC and only some of them are properly food safe. See more here https://www.howtoaquaponic.com/designs/is-pvc-food-safe/

Thanks! That's quite the dire warning about PVC cement. Maybe I'll stick with silicone tubing for my first setup.
