Researchers have found that urea from urban and agricultural runoff, generally ignored as a pollutant by environmental agencies, contributes to growth of potentially toxic blooms of a common marine algae.
SANTA CRUZ, CA, February 28, 2000 - In nature, there's no accounting for taste. New research shows that a common type of marine algae may prefer urea, an organic nitrogen compound found in urine and in agricultural and urban runoff, over inorganic fare such as ammonium and nitrate that occurs naturally in the ocean. When excess nutrients cross their paths, these single-celled organisms, called dinoflagellates, can grow into potentially toxic blankets of algae commonly known as red tides.
