Mice Exposed to Low-Level Arsenic in utero Become Obese Adults

Caption

Mice exposed to low-level arsenic in utero become obese adults. The control mouse, left, was not exposed to arsenic during embryonic development and is a normal weight. In comparison, mice exposed to arsenic at 10 parts per billion, center, and 42 parts per million, right, are visibly heavier. The study also determined that these exposed mice entered puberty earlier than controls.
