WAS BEDEUTET DIELDRIN AUF ENGLISCH
Dieldrin
Dieldrin ist ein chlorierter Kohlenwasserstoff, der ursprünglich 1948 von J. Hyman \u0026 amp; Co, Denver, als Insektizid. Dieldrin ist eng mit aldrin verwandt, das weiter reagiert, um Dieldrin zu bilden. Aldrin ist nicht giftig für Insekten; Es wird im Insekt oxidiert, um Dieldrin zu bilden, welches der Wirkstoff ist. Sowohl Dieldrin als auch Aldrin werden nach der Diels-Alder-Reaktion benannt, die zur Bildung von Aldrin aus einer Mischung von Norbornadien und Hexachlorcyclopentadien verwendet wird. Ursprünglich in den 1940er Jahren als Alternative zu DDT entwickelt, erwies sich Dieldrin als hochwirksames Insektizid und wurde in den 1950er bis Anfang der 1970er Jahre sehr verbreitet. Endrin ist ein Stereoisomer von Dieldrin. Allerdings ist es ein extrem anhaltender organischer Schadstoff; Es lässt sich nicht leicht brechen. Darüber hinaus neigt es dazu, zu biomagnieren, wie es entlang der Nahrungskette geführt wird. Langfristige Exposition hat sich als sehr giftig für eine sehr breite Palette von Tieren einschließlich Menschen, weit größer als die ursprünglichen Insekten Ziele. Aus diesem Grund ist es jetzt in den meisten der Welt verboten. Es wurde mit gesundheitlichen Problemen wie Parkinson, Brustkrebs und Immun-, Reproduktions- und Nervensystemschaden verknüpft.
