Chronic ingestion of metals altered social behavior in male prairie voles. Male prairie voles that consumed either Hg++ or Cd++ in their drinking water spent significantly less time in contact with an unfamiliar, same-sex conspecific than did males that received only unadulterated water. Social contact did not differ between males that received Hg++ or Cd++. In contrast, metals ingestion did not alter the amounts of time females spent in contact with a same-sex stranger. * p < 0.002.
