Concentrated hydrogen dioxide toxicity to non-target organisms: Which group is listed as highly toxic to concentrated hydrogen dioxide products?

• A. Bees and other insects
• B. Birds and fish
• C. Amphibians
• D. Reptiles

Answer: (A)

Concentrated hydrogen peroxide products carry labels that flag non-target organisms that are especially at risk, and pollinators stand out as the group listed as highly toxic. Bees and other insects are particularly vulnerable because they come into direct contact with treated surfaces, ingest residues from nectar or pollen, and can be exposed when plants are in bloom. This is why labels emphasize protecting pollinators, such as by avoiding spraying on flowering crops and by following drift and timing guidelines to keep bees away from treated areas. While birds, fish, amphibians, and reptiles can be affected by oxidizers in some contexts, the strongest, most specific caution on these products is about bees and other insects, making them the group identified as highly toxic.
