Borate Hazards

"Boric acid and borates are naturally occurring compounds containing the element born.  They are widespread and abundant in soil, water and food.

Boric acid and its chemical relatives kill insects by acting as a stomach poison and by absorbing the waxes that protect insects from drying out.

The most significant health concerns associated with exposure to boric acid and borates are their ability to reduce successful reproduction.  In laboratory tests, boric acid has damaged sperm, increased the frequency of prenatal mortality (miscarriages), reduced birth weight and caused a variety of birth defects.  In general, these effects occurred during relatively high exposures to boric acid."
