incidental pollution(Замърсяване причинено от нефтени разливи, случайно изпускане на радиоактивни вещества, имисия във водоеми или в атмосферата на химически вещества, произлизащи от промишлена дейност)
accidental release of organisms Genetically engineered organisms that are released in the environment by mistake; once released they may exhibit some previously unknown pathogenicity, might take over from some naturally occurring bacteria (possibly having other positive functions which thus are lost) or pass on some unwanted trait to such indigenous bacteria. There is also concern that an uncontrolled genetic mutation could produce a form with hazardous consequences for the environment
