Heavy simbi: The Phantom pakutyisidzira

Chemical indasitiri anoita yedu inonakidza uye dzakanaka. Asi pane marapirwo - pakuonekwa iri hwaiitwa zvinhu kuti hazvisi chaivo kwaari. Zvirokwazvo munhu wose anzwa chinhu pamusoro rinorema simbi. Asi kwete vose anoziva tsanangudzo muchikwata ichi zvinhu.

Heavy nesimbi - zvinhu vane arambe achirema zvikuru simbi iri chairo rawakajaira uye zvinowanika diki zvakawanda. Asi nemamiriro ezvinhu nevanhu, vane simba chaizvo pamusoro zvinomera, mhuka uye vanhu. The ndechokuti dzimwe inova kwakakuomerai maladjusted kuti kuwanda kwenyaya mugadziriro zvakadaro, kana uri muviri womunhu, mhuka kana chirimwa muviri.

Heavy simbi mumvura nguva nenguva azviise dzakasiyana dzepasi. Saka kuJapan. A chirwere anokonzerwa nokuwedzera wevasungwa pamusoro mekuri, rinonzi Minamata chirwere. Vakafa musi vanhu vanopfuura zana, uye uwandu husina kuverengwa zviuru. Vasingafari vanhu vanonzwa simba simba, zvakanga zvakaoma chaizvo kuti: gait vakava vachinyara, munda chiratidzo nhete, makumbo bindira. In chakakomba kacho akasvika kurasikirwa nechaanoona, uye rufu zvachose. Zvino ichi chiitiko chinosuruvarisa mu 1953godu.

Chikonzero chaiva chokuti iri Minamata Bay mainozonodira rwizi. A akabatanidza tsvina makemikari chirimwa mairi. The kuora uswa hwemvura pamusoro mekuri rwaiwanikwa methyl nemekiyuri - chinhu chaizvo muchetura fuma. The kumusoro pamusoro ngetani chikafu atorwa, chikuru wevasungwa kukura. Most chepfu kuunganidza nehove dzinodya dzimwe. Kana methylmercury kuwira muviri womunhu, izvozvo rinoungana muuropi, zvichiita zvishoma nezvishoma zvose zvinorondedzerwa ne nechepakati huta matambudziko hurongwa.

Uyewo Japan, kwakava nyaya iri Dzintsu rwizi bheseni pakati 20s remakore rechi20. Pane nguva kwakanga chirwere chakaipisisa: vanhu akaremara mapfupa, uye vakafa pamwe kugomera, translatable mu Russian se "kurwara!". kutya uku kwakatora kusvikira 70, kana varwere Tendeuka uye akaenda kumatare wekambani, izvo batanidza kupinda munzizi cadmium ari Zvinoumba tsvina yangu.

Heavy nesimbi muvhu vari ishoma, asi achiri varumbidzwa varimi kuongorora kuvapo ravo ivhu pamberi chirimwa miti yenyu. Pashure pezvose, kana iwe havatamburi uye vanhu nemhuka, uye zvirimwa. Uye hazvisi chete mutsika zvisingagamuchirwi uye kurangwa, asiwo kunobatsira.

Chii chinonyanya kakawanda zvinowanikwa muvhu? Chokutanga, tungamirira. Kwayakanga yabva? Kubva chiutsi magasi. Ndokusaka hazvina zvakakodzera kuunganidza michero uye howa rworudyi parutivi pomugwagwa. Uye kana paine munda? In yakabudirira nyika kare vakamira chaiwo inodiwa. Dzimwe nguva kutungamirira ivhu murombo-unhu Tupukanana nomushonga wezvipembenene. Saka kana ukatenga mishonga yezvipembenene mugadheni, iva nechokwadi kungowanawo paIndaneti kuti dzi dzavo uye outs.

Oh isu vakati cadmium. Anogona kuva ivhu. Ake ambotaurwa chakaunzwa pasi pamwechete phosphorus fetiraiza. Zvadaro vanhu vakava kunyatsoteerera, asi dzimwe nguva refu kuwanda cadmium ari muchikwata ichi fetiraiza vanosangana nhasi.

Arsenic inowanikwa zvibereko marara, umo wevasungwa kuwedzera, saka zviri chokwadi kuti marara kwemarara - mumwe mushonga kuti zvakatipoteredza wenyama.

Kana vasati unorema pakusvibiswa pamwe inorema nesimbi anobatsira dzakabudirira, makemikari indasitiri choutsi, zvino mukuru dambudziko wakabatana nhamba yavo yakawedzera zvimwe fetiraiza. Potashi fetiraiza haana kukwanisa dzine cadmium, asi phosphorus anogona. Naizvozvo zviri nani kuti vanosarudza vatorwa, pane zvakawanda yakasimba kuzvidzora.

Not munokosha zvikuru kutya inorema nesimbi, asi kana kwaunogara akanga kwakakwidziridzwa kugutsikana kwavo, unofanira mwedzi mumwechete pagore yakachena zvipenyu nezvakazvipoteredza ezvinhu.
