Ngamunye wethu usekhaya kunezinto eziqukethe iMercury. Isibonelo, ama-thermometer alinganisa izinga lokushisa egumbini, amadivaysi ezokwelapha, amalambu okusindisa amandla e-compact fluorescent. Ake sibheke ukuthi kuyingozi kangakanani isihlalo esiphukile se-thermal noma izibani ezikhona ze-fluorescent endlini ngayinye?
Ku-thermometer ejwayelekile uqukethe kuze kufike ku-2 g we-mercury, kumalambu wokonga amandla angabi ngaphezu kuka-2,5 mg, i.e. cishe izikhathi eziyi-1000 ngaphansi.
Ngakho-ke, kuzolunga ukuthi isibani esisodwa esihlukanisiwe kumthengi ekhaya asiyona ingozi kangako. Kodwa-ke, mhlawumbe wonke umuntu uyazi ukuthi iMercury iyinsimbi. Kepha abaningi bakhohlwa ukuthi uyingozi enkulu. Okokuqala, ukuhwamuka kwayo kuyingozi. I-Mercury ikhipha egumbini kanye nokushisa kwe-zero. Izimpawu zobuthi zibonakaliswa phakathi nosuku futhi zivezwa ngobuthakathaka obujwayelekile, ubuhlungu bekhanda, ubuhlungu lapho bugwinya, kukhulisa izinga lokushisa.
Yini okufanele ngiyenze uma i-thermometer noma i-luminescery light bulb iphumelele?
Ukwehla kwezinyathelo kuyizinyathelo zokususa imishini ye-mercury mechanical, ye-physicochemical noma amakhemikhali.
1. Umgwaqo
Okokuqala, vula ngokushesha wonke amawindi nezicabha, cela wonke umuntu ukuthi aphume egumbini aze alethe izilwane ezifuywayo. Lapho ufeza, enye ingxenye yama-mercury vapors ngokwemvelo izonyamalala. Futhi, vala iminyango kuwo wonke amanye amakamelo.
2. Ukuqoqwa kwemishini yeMercury
Ukuqoqa i-Mercury akunakwenzeka ukusebenzisa umshanelo, i-mop noma i-vacuum cleaner. Ngaphandle kwalokho, ngemuva kokuxhumana ne-mercury, kuzodingeka ukuthi ilahlwe kanye ne-mercury eqoqiwe.
Ukubuthana kuphela kumagilavu nemikhiqizo yokuvikela ukuphefumula (i-tank-gauze bandage).
Sincoma ukusebenzisa:
irabha elisethafeni;
I-tassel evamile enamashidi aminyene ephepha noma amakhadibhodi;
i-scotch tape noma iribhoni elinamathelayo;
isiponji.
Ngakho-ke, faka ibhandeji ye-gauze kanye namagilavu enjoloba. Kuyadingeka ukuqoqa amabhola we-mercury kuyo yonke indawo yegumbi. Kungcono ukusebenzisa ibhulashi elimanzi kulokhu, ibhulashi. Amabhola amakhulu asuswa ephepheni bese uthele embizeni enesixazululo se-manganese, futhi okuncane kungaqoqwa nge-pipette noma i-scotch (ngisho nesinkwa sesinkwa) futhi uqiniseke ukuthi ubeka embizeni efanayo.
3. Ukwelashwa ngamakhemikhali
Umongo wale ndlela ukuthi izinsalela ze-merkury zisabele ngamakhemikhali, futhi enqubweni yokusabela kwabo, amakhompiyutha angewona aguqukayo akhiwa ngendlela yosawoti we-mercury, okulandelayo adotshwa kalula.
Thatha ama-2 amagremu ama-manganese, uwukhiphe nge-1 litre lamanzi. Kuvela ikhambi elingu-0.2% elinamanzi e-potanganum permanganate. Ungasebenzisa futhi elimhlophe noma amanye ama-ejenti aqukethe ama-chlorine.
Okulandelayo, cubungula indawo (phansi, Slots phakathi kwamabhodi, izindonga), lapho isibani (i-CLF) noma amanye amadivaysi aqukethe i-mercury. Ngemuva kokuthi ucubungule lezi zindawo ezine-soap-soda solution (4% wensipho incibilika kukhambi elingu-5% elinamanzi). Futhi-ke, udinga ukuphinda izikhathi ezi-3-4 ezinsukwini ezimbalwa.
Ungakhohlwa ukuthi ngaso sonke isikhathi ngesikhathi sokuhlanza igumbi kufanele kufakwe umoya. Nge-Venist ndiaveration, ukugcwala kwe-mercury vapor kuzobuyela kokujwayelekile kungakapheli izinyanga ezi-1-3. Kepha, njengomthetho, uma konke kwenziwa ngendlela efanele futhi kuqoqe iMercury ngokwanele ngokushesha, usongo olukhulu empilweni lesi simo esiphuthumayo aluthwali. Khumbula, ibhange eline-mercury eliqoqwe ngaphandle kwecala alikwazi ukuphonswa ebholeni noma kubi, ugeze ungene endaweni yokuthuthwa kwendle, uveze sonke isakhiwo sokuhlala. Kufanele ucele uMnyango Wezimo Eziphuthumayo ngo-101 noma u-112, ukusho ukuthi kwenzekani lesi sigameko, futhi uzokutshela ukuthi kufanele wenze kanjani kahle nokuthi ungawusebenzisa kanjani i-mercury yezentengiselwano.
