Tasiri akan Karan Halitta na Kasa

Ƙananan ƙwayoyin ƙasa suna taka muhimmiyar rawa wajen kiyaye haifuwar ƙasa, hawan keke na gina jiki, da lafiyar ƙasa gabaɗaya. Sodium cyanide, lokacin da yake cikin ƙasa, zai iya yin mummunar tasiri akan waɗannan ƙananan ƙwayoyin cuta. Ko da a ƙananan ƙananan ƙira, cyanide na iya hana ayyukan ƙwayoyin cuta na ƙasa, fungi, da sauran ƙwayoyin cuta masu amfani. Alal misali, yana iya tarwatsa nitrogen - ikon gyara wasu ƙwayoyin cuta, waɗanda ke da mahimmanci don canza nitrogen na yanayi zuwa wani nau'i da tsire-tsire za su iya amfani da su.

Sodium cyanide yana narkewa sosai a cikin ruwa, kuma duk wani sakin da aka saki a cikin ruwa yana iya haifar da bala'i. Lokacin da ya shiga cikin ruwan saman, kamar koguna ko tafkuna, yana iya narkewa da sauri ya samar da ions cyanide. Ko da a ƙananan ƙwayoyin cuta, cyanide yana da guba sosai ga kwayoyin ruwa. Kifi, invertebrates, da amphibians suna da damuwa musamman ga bayyanar cyanide. Yana iya tsoma baki tare da tsarin numfashinsu, yana hana karɓar iskar oxygen.
