Avoid Commercial Bleach.
It is best to avoid most commonly available bleach, sodium hypochlorite, a moderately toxic chlorine salt that can bond with other chemicals to form cancer-causing organochlorines in the wastewater system.
'Natural oxygen safe bleaches' are commercially available (found primarily in the health food store marketplace), and are based on hydrogen peroxide. The best choice is to buy commercial non-chlorine bleaches instead of making your own version using store-bought 3% hydrogen peroxide because commercial brands include oxygen bleach stabilizers to help reduce the product's reactivity in the environment.
