Fertilizer chemicals linked to animal developmental woes
28.08.2010 20:00 1 views 0 comments
 Fertilizer chemicals may pose a bigger hazard to the environment -- specifically to creatures that live in water -- than originally foreseen, according to new research. Toxicologists show that water fleas take up nitrates and nitrites -- common chemicals used primarily in agriculture as fertilizers -- and convert those chemicals into nitric oxide. Nitric oxide can be toxic to many organisms. Read more »
