ЧТО ОЗНАЧАЕТ СЛОВО DIELDRIN
Дильдрин
Дильдрин представляет собой хлорированный углеводород, первоначально полученный в 1948 году J. Hyman \u0026 amp; Co, Денвер, в качестве инсектицида. Дильдрин тесно связан с альдрином, который далее реагирует с образованием дильдрина. Олдрин не токсичен для насекомых; он окисляется насекомым с образованием дильдрина, который является активным соединением. Как дильдрин, так и альдрин названы в честь реакции Дильса-Альдера, которая используется для образования альдрина из смеси норборнадиена и гексахлорциклопентадиена. Первоначально разработанный в 1940-х годах в качестве альтернативы ДДТ, дильдрин оказался высокоэффективным инсектицидом и очень широко использовался в период с 1950-х по начало 1970-х годов. Эндрин является стереоизомером дильдрина. Однако это чрезвычайно стойкий органический загрязнитель; это нелегко сломать. Кроме того, он имеет тенденцию к биомагнитизации, поскольку он передается вдоль пищевой цепи. Долгосрочная экспозиция оказалась токсичной для очень широкого круга животных, включая людей, намного больше, чем для исходных целей насекомых. По этой причине в настоящее время он запрещен в большинстве стран мира. Это связано с проблемами со здоровьем, такими как болезнь Паркинсона, рак молочной железы и иммунный, репродуктивный и нервной системы.
