Butylated Hydroxyanisole is a synthetic antioxidant used in food packaging. It can leach into water from plastic containers and may disrupt hormones or increase cancer risk.

Butylated Hydroxyanisole (BHA) has been used as a food preservative since 1947. This synthetic antioxidant is commonly found in food packaging and plastics. BHA can enter drinking water through industrial processes or when plastic containers degrade over time. Water quality tests measure BHA levels in parts per billion (ppb). While its use is regulated in food, there's growing concern about its presence in water due to potential hormone-disrupting effects. Research on its long-term impact on human health is ongoing.
