Ответ:

Химические, токсичные вещества, и тяжелые металлы

Объяснение:

Хотя химикаты и токсичные вещества естественным образом существуют в природе, в последние 250 лет человек активно наносит вред окружающей среде, используя искусственные загрязнители техногенного происхождения. Существует множество источников такого губительного воздействия, приносимый ими ущерб подчас колоссален, это особенно ощутимо в областях тяжелой промышленности и сельского хозяйства. Экосистему, загрязненную токсичными химикатами, очень трудно отчистить, да и на практике этим редко кто планомерно занимается. Между тем снижение производства вредных соединений и минимизация их выброса является важной частью сохранения окружающей среды.
