Chromium found in right whales

A study performed by the University of Southern Maine has found that the element chromium may be negatively affecting the reproductive abilities of right whales.  Chromium is an industrial pollutant, commonly leftover after metal-finishing, leather tanning, and textile-dying.  Researchers found chromium present in the skin, lungs, and testes of right whales.

The North Atlantic right whale (Eubalaena glacialis) is the most severely endangered whale, according to MaineToday.com.  Only 300 of the animals are left in existence.  The whale is dark grey or black, and commonly distinguished by callosities on its head.
