Nakuba ukusetshenziswa kwamabhethri kuncipha, ukungcoliswa kwebhethri kuseyinkinga ekhathazayo. Futhi ukungcola okubangelwa izinhlobo ezahlukene zamabhethri kuyehluka kakhulu. Ibhethri le-mercury lingangcolisa amalitha ayizinkulungwane ezingama-600 amanzi, ibhethri le-alkaline lingangcolisa amalitha ayizinkulungwane eziyi-167 kanye nebhethri le-oxide yesiliva lingangcolisa amalitha ayizinkulungwane eziyi-14. Lokhu kwenza abantu abaningi bazibuze amabhethri angcolisa kangakanani.
Kulesi sihloko sizokutshela ukuthi angakanani amabhethri angcolisa nokuthi yini engenziwa ngakho.
Isimo sokungcoliswa kwebhethri
Zingu-40 kuphela izinto ezine-alkaline ezinganele ukungcolisa amalitha amanzi ayizigidi ezingu-6,5, alingana nosayizi wechibi lokuntywila. I-Mercury inamandla okubangela umdlavuza futhi iyakwazi ukunqwabelana ezintweni eziphilayo. Ukuchayeka isikhathi eside kwalesi sakhi kungaba nemiphumela elimazayo ebuchosheni, ezinso nasekukhuleni kombungu, okungase kuholele ekukhubazekeni kwengqondo, ukukhubazeka kwamakhono emisipha nokukhuluma, ukuntuleka kokuxhumana, izinkinga zokubona, nokuquleka.
Ukukhishwa kwe-mercury ezindaweni zokulahla imfucumfucu kuholela ekungcolisweni kwakho kokubili kwamanzi nenhlabathi futhi ekugcineni kungene ochungechungeni lokudla njengoba inqwabelana ezicutshini zezinhlanzi.
Isimiso sezinzwa, izinso, nesimiso sokuzala konke kusengozini yokulimala ngenxa yomthofu. Ngenxa yemvelo yawo engonakali, umthofu unamandla okuhamba amabanga abalulekile emoyeni ngaphambi kokuthi uzinze. Iphinde ibe nokuthambekela kokubophezela ezinhlayiyeni zenhlabathi futhi ingangena emanzini angaphansi komhlaba.
Izakhiwo ze-neurotoxic ze-lithium ziyenza ibe yingozi kuzo zombili izinso kanye nesistimu yokuphefumula. Ubuthi be-lithium bungabangela izimpawu eziningi ezinzima, okuhlanganisa ukwehluleka ukuphefumula, ukucindezeleka kwe-myocardial, i-pulmonary edema, nesimo esijulile sokuquleka. Isimiso sezinzwa siphinde sithinteke kabi, okungaholela ekubeni i-coma noma ngisho nokufa. Ukwengeza, i-lithium inekhono lokungena kalula emanzini angaphansi komhlaba, okwenza kube yingozi enkulu emithonjeni yamanzi angaphansi komhlaba.
I-Cadmium, into eyaziwa ngezici zayo ze-carcinogenic, imele usongo olukhulu ohlelweni lokuphefumula lapho ihogelwa ngobuningi, kuyilapho ukungenwa kwayo kubangela ukulimala kwezinso. Amazinga aphezulu okuchayeka angaba nemiphumela ebulalayo. Ukusetshenziswa kokudla noma amanzi angcoliswe i-cadmium kubangela ukucasuka kwesisu, ukuqala izimpawu ezifana nokuhlanza kanye nesifo sohudo. Ukudedelwa kwe-cadmium emkhathini nasemithonjeni yamanzi kwenzeka ikakhulukazi ngokuchithwa kwemfucumfucu noma ukuchitheka kwemfucuza yasendlini ngephutha, okuwuvumela ukuba uhlakazeke amabanga amade.
Isikhumba sithintwa i-nickel, futhi ukuhogela inani elikhulu kubangela ukuthuthukiswa kwe-bronchitis engapheli, kanye nomdlavuza wamaphaphu kanye ne-sinus. Ukushiswa kukadoti kukhipha lesi sakhi emkhathini, lapho sinamathela ezinhlayiyeni zothuli ezigcina sezihlala phansi.
Izixazululo zokugwema ukungcola izinsuku
Ukuze kuxazululwe le nkinga, kubalulekile ukuguqula izinqubo futhi usebenzise indlela yokusebenzisa eqaphela ebeka indawo ezungezile kuqala. Qinisekisa ukuthi uneziqukathi ezifanele zokugcina amabhethri angasetshenzisiwe, ugweme ukulahlwa kwawo ngokushiswa. Nakuba izinhlelo zokuqoqa amabhethri zivame ukusetshenziswa ezitolo noma kwezinye izindawo, kubalulekile ukubuza endaweni yokugcina yamabhethri aqoqiwe ukuze kubhekwane nenkinga ngempumelelo.
Khetha ukusebenzisa amabhethri aphinde ashajwe esikhundleni salawo alahlwayo, njengoba enamandla okushintsha amabhethri asetshenziswa kanye angu-300. Noma nini lapho kungenzeka, zama ukunciphisa ukusetshenziswa kwazo.
Kufanele ukhethe ukusebenzisa imikhiqizo esebenzisa amandla omoya, elanga noma kagesi. Khetha imikhiqizo engaxhunywa kugesi oyinhloko. Lezi zinketho azigcini nje ngokungcolisa, kodwa futhi zinokusebenza kahle kwamandla okuphezulu.
Ingxenye ebalulekile yamabhethri asetshenzisiwe yenzelwe izinjongo zokuzijabulisa, njengomculo, imidlalo namakhamera. Kunconywa ukunciphisa ukusetshenziswa kwamabhethri kule misebenzi. Umuntu kufanele Gwema ukuthenga amabhethri omgunyathi ngoba akukhona nje kuphela ukuthi akukho emthethweni kodwa futhi anesikhathi esifushane sokuphila futhi kube yingozi enkulu endaweni ezungezile.
Ukuqinisekisa ukulahlwa okufanele, kubalulekile ukukugwema ukulahla kudoti, ezindaweni ezivulekile noma ezindaweni zomphakathi. Thatha izinyathelo zokuphepha ukuze uwavimbele ukuthi angangeni emanzini noma amasistimu okukhipha amanzi, futhi ugweme ukuwashisa, njengoba lokhu kungakhipha izinsimbi eziyingozi emoyeni.
Uma i-casing yensimbi yamabhethri isigqwalile, kubalulekile ukugwema ukuwagqiba, ngoba anamandla okungcolisa inhlabathi, inhlabathi engaphansi namanzi.
Angcolisa kangakanani amabhethri?
Ukusebenza kwamadivayisi asetshenziswa kakhulu njengezidlali ze-MP3, amakhamera nezilawuli kude kuncike kumabhethri. Nokho, uma lawa mabhethri eselahliwe, Izinga lokungcoliswa kwemvelo alinakwa.
Ukusebenza kwezinto zansuku zonke ezifana nezidlali zeMP3, amakhamera, izilawuli kude nokunye kuncike kuzo. Nokho, ukuzilahla ngaphandle kokucabangela kuholela ekushayweni indiva izinga imvelo engcoliswa ngalo.
Naphezu kobukhulu bawo obuncane, anomthelela omkhulu ngenxa yokusetshenziswa kwawo kabanzi. Le mishini emincane iguqula ngempumelelo amandla amakhemikhali abe amandla kagesi. Nokho, imvelo yayo ebonakala ingenangozi ingase ibe nayo imiphumela eyingozi uma ilahlwa ngokungafanele ngemfucuza evamile.
Izinto ezinobuthi ezifana ne-mercury, i-lead, i-lithium, i-cadmium ne-nickel Bakha u-30% wokwakheka kwenqwaba ngayinye. Uma la mabhethri eseyifezile inhloso yawo futhi engasasebenziseki, alahlwa budedengu agcine esezimpondweni eziseduze nezindawo zasemadolobheni. Lapha, kanye nokunye udoti, kancane kancane ziqala ukubola, zibe usongo olukhulu endaweni ezungezile kanye nazo zonke izinhlobo zokuphila, kokubili komuntu nokungeyena umuntu. Lokhu kukhathazeka okukhulu kuphakanyiswe isifundiswa, sigcizelela umthelela omubi walawa mabhethri alahliwe empilweni yemvelo yethu.
Izinga lomonakalo obangelwa amabhethri lihlobene ngokuqondile nosayizi wawo, namabhethri amancane anomthelela omkhulu wokungcolisa. Isibonelo, ibhethri elivamile eliphonswe phansi lingangcolisa amalitha amanzi angu-3.000, kuyilapho ibhethri le-alkaline eliqukethe i-mercury lingangcolisa amalitha angu-160.000, ngisho nebhethri elincane lewashi lingangcolisa amalitha amanzi angu-600.000.
Okukhathaza kakhulu ukuthi, naphezu kwalolu lwazi, amabhethri awaphathwa ngokuhambisana nemithetho yokulahlwa kwemfucuza eyingozi. Kunalokho, ilahlwa ezindaweni zokulahla imfucumfucu ezivamile zikamasipala, lapho izinqubo zokuvutshelwa kukadoti zonakalisa izinto ezipakishiwe futhi zikhiphe izinto ezinobuthi. Lezi zinto zibe sezingena emhlabathini nasezindaweni zamanzi, zibangele ukungcola.
Ezimweni eziningi, amaseli namabhethri alahlwa ezindaweni zokulahla imfucumfucu, okubangela ukukhishwa kwezinto ezinobuthi kakhulu kanye ne-carcinogenic, njengama-dioxin nama-furan, okwandisa amazinga okungcola.
Ngethemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi mangakanani amabhethri angcolisa.
