Njodzi dzeSodium Cyanide kune Hove uye Dzimwe Mhuka Dzemhuka

ziviso

Sodium cyanide (NaCN) musanganiswa une muchetura unoisa kutyisidzira kukuru kune hove nezvimwe Wildlife. Kushandiswa kwaro kwakapararira mumaindasitiri akasiyana siyana, sekuchera goridhe, uye zviitiko zvisiri pamutemo sekubata hove cyanide, zvakakonzera kukanganisa pazvipenyu zvemvura uye zvepasi. Ichi chinyorwa chinoongorora njodzi dzakananga dze sodium cyanide kune zvisikwa zvisina simba izvi.

Acute Toxicity

Cyanide inonyanya kukosha

huturu kuhove. Kunyange pakudzikama kwakaderera, kunogona kuva nemigumisiro inouraya. Kana cyanide iripo mumvura, hove dzinoitora kuburikidza nemagill avo. Iyo cyanide ion (CN-) inosunga kune iron mu cytochrome oxidase enzyme mumasero ehove. Kusunga uku kunokanganisa cheni yekutakura erekitironi, iyo yakakosha pakufema kweaerobic. Somugumisiro, hove hadzikwanisi kushandisa okisijeni zvakanaka, zvichiita kuti masero asafe.

Semuenzaniso, zvidzidzo zvakaratidza kuti kana cyanide ion concentration mumvura inosvika 0.04 - 0.1mg / L, inogona kuuraya kune marudzi akawanda ehove. Muzviitiko zvekurasa kwecyanide kana kuraswa zvisina kufanira kwecyanide - ine tsvina yemumaindasitiri mumitumbi yemvura, hove dzakakura dzakaonekwa. Mune dzimwe nzvimbo dzegoridhe-mumigodhi umo cyanide inoshandiswa mukuchera, kuburitswa netsaona kwakakonzera kufa kwezviuru zvehove munzizi nehova dziri pedyo.

Sub - inouraya Migumisiro

Kunyangwe kana hove dzikasafa nekukasira kubva pakuratidzwa kwecyanide, dzinogona kutambura kubva kune-inouraya mhedzisiro. Izvi zvinogona kukanganisa kukura kwavo, kubereka, uye maitiro. Cyanide exposure inogona kuita kuti hove dzideredze kudya, izvo zvinozokanganisa kukura kwadzo. Inogonawo kukanganisa maitiro avo ekubereka. Hove dzechikadzi dzinogona kuburitsa mazai mashoma, uye mazai anogona kunge aine mwero wakaderera wekuchechenya.

Pamafambiro, hove dzakafumurwa kune zvinouraya mazinga ecyanide dzinganyanya kufa, kusakwanisa kudzivirira zvikara, uye kusagona kushambira. Izvi zvinovaita kuti vanyanye kunetseka munzvimbo dzavanogara.

Migumisiro Yakananga Panzvimbo Dzinogara Hove

Cyanide inogonawo kuva nemigumisiro isina kunanga panzvimbo dzehove. Munzvimbo dzemugungwa, kubata hove dzecyanide, tsika isiri pamutemo inonyanya kushandiswa kubata hove mhenyu dzekutengesa mumvura uye dzimwe nguva dzekudya, chave chiri kunetsa kukuru. Kana vabati vehove vachikwenya Sodium Cyanide mucoral reef kuti rirove hove, cyanide haingokanganisi hove dzakanangwa chete asiwo inokuvadza matombo emakorari.

Makoral reef inzvimbo dzinokosha dzehove, dzinopa chikafu, pekugara, uye nzvimbo dzekuberekera. Cyanide inogona kukonzera coral bleaching, iko kudzingwa kwesymbiotic algae kubva kumacoral polyps. Mumadhodhi akaderera, inogona kukanganisa biology yemakorari, uye kana yakakwira, inogona kuuraya makorari zvachose. Kana makorari afa, chipenyu chose chezvipenyu chinotanga kuparara, uye hove dzinotsamira pamatombo acho kuti dzirarame dzinosiyiwa dzisina pokugara pakakodzera.

Aquatic Invertebrates

Aquatic invertebrates, senge crayfish, mussels, uye zooplankton, zvakare inonzwisisa zvakanyanya kune cyanide. Zvakafanana nehove, cyanide inogona kukanganisa maitiro avo ekufema uye metabolic. Zooplankton, iyo inoumba hwaro hwechikafu chemumvura, inonyanya kunetseka. Kana huwandu hwezooplankton hukadzikiswa nekuratidzwa kwecyanide, inogona kuve nemhedzisiro pawebhu yese yezvokudya zvemumvura. Semuyenzaniso, hove dzinovimba ne zooplankton sechikafu dzinenge dziine zvishoma zvekudya, izvo zvinogona kuwedzera kukanganisa kurarama nekukura kwavo.

Mussels nemamwe bivalves anogona kusefa cyanide - ine mvura, ichiunganidza muchetura mumatishu avo. Ikoku hakusati kuchikanganisa bedzi utano hwavo vamene asiwo kunopa ngozi kumhuka dzinodya padziri, dzakadai seshiri namanoti.

Mhuka Dzepasi

Mhuka dzepanyika dzinogona kuoneswa cyanide nenzira dzakasiyana. Munzvimbo dziri pedyo negoridhe - mabasa ekuchera, mhuka dzesango dzinogona kusangana necyanide - ine mvura ine tsvina. Semuenzaniso, mhuka dzinonwa kubva muhova kana madziva akasvibiswa necyanide kubva mumarara emugodhi dzingave nehupfu.

Dzimwe shiri dzinogona kukwezvwa necyanide - ine madziva ekumisa panzvimbo dzemigodhi. Aya madziva anogona kunge ane huwandu hwe cyanide, uye kana shiri dzikagara mukati madzo kana kudya mhuka dzave dzichisangana ne cyanide, dzinogona kuve nechepfu. Pamusoro pezvo, zvipuka zvidiki zvinogara padyo nenzvimbo dzemaindasitiri panoshandiswa cyanide zvinogona kupinza netsaona cyanide - ivhu rakasvibiswa kana zvidyarwa, zvichikonzera kurwara kana kufa.

Njodzi dze Sodium cyanide kubata hove nedzimwe mhuka dzesango zvakakosha uye zvinosvika kure. Kubva pachepfu yakananga iyo inokonzera kufa nekukurumidza kusvika kunguva refu-inouraya mhedzisiro uye kuparadzwa kwenzvimbo dzekugara, cyanide inokonzeresa kutyisidzira kwekupona uye kugara zvakanaka kwemarudzi akawanda. Zvakakosha kuti mitemo yakasimba itevedzwe kudzivirira kushandiswa zvisiri pamutemo kwecyanide, sekuredza cyanide, uye kuti maindasitiri anoshandisa cyanide aite kwakaringana kutambisa marara uye matanho ekuchengetedza kuderedza. kusvibiswa kwezvakatipoteredza. Kuchengetedza zvisikwa izvi zviri munjodzi kubva munjodzi dzecyanide kwakakosha pakuchengetedza chiyero uye kusiyana-siyana kwezvipenyu zvezvipenyu zvedu.c
