Ho qoba tšilafalo ea heavy metal, e ka lebisang ho hlaha ha mafu a tebileng a kang ho hloleha ha liphio kapa mofetše, ho etsa mohlala, ho bohlokoa ho fokotsa ho kopana le mefuta eohle ea tšepe e boima e kotsi bophelong bo botle.

Mercury, arsenic le lead ke mefuta e sebelisoang haholo ha ho etsoa lintho tse fapaneng tsa bophelo ba rona ba letsatsi le letsatsi, joalo ka mabone, lipente esita le lijo, ka hona, ke tsona tse ka bakang chefo habonolo.

Bona matšoao a mantlha a ts'ilafalo ea tšepe e boima.

Ho qoba likotsi tsohle tsa bophelo bo botle ho bohlokoa ho tseba hore na ke lintho life tse nang le lisebelisoa tsena tse ngata ho tseba se o lokelang ho se fetola kapa ho se felisa puong ea hau ea letsatsi le letsatsi:

1. Mokhoa oa ho qoba ho kopana le Mercury

Mekhoa e meng ea ho qoba ho pepesehela mercury ho sa hlokahale e kenyelletsa:

• Qoba ho ja litlhapi tse nang le mercury e ngata khafetsa, tse kang mackerel, swordfish kapa marlin, mohlala, ho khetha saalmon, sardine kapa li-anchovies;
• Ho hloka lintho tse nang le mercury hae ka sebopeho sa eona, joalo ka pente, libetri tse sebelisitsoeng, mabone a sebelisitsoeng kapa li-thermometer tsa mercury;
• Qoba ho roba lintho ka mokelikeli oa mercury, joalo ka mabone a fluorescent kapa li-thermometer;

Ho phaella moo, maemong a likoti le mekhoa e meng ea phekolo ea meno, ho eletsoa hape hore u se ke ua sebelisa ho tlatsa meno ka mercury, ho fana ka khetho ho li-resin, ka mohlala.

2. Mokhoa oa ho qoba ho kopana le Arsenic

Ho qoba tšilafalo ea arsenic, ho bohlokoa ho:

• Ho tlosa patsi e tšoaroang ka lintho tse bolokang le CCA kapa ACZA kapa kenya seaparo sa sealant kapa pente e se nang arsenic ho fokotsa ho kopana;
• Se ke oa sebelisa manyolo kapa libolayalehola le monosodium methanearsonate (MSMA), calcium methanearsonate kapa cacodylic acid;
• Qoba ho noa meriana ka arsenic, a botsa ngaka ka moriana oo a o sebelisang;
• Boloka hantle metsi a bolailoeng ka moriana le ho lekoa ke k'hamphani e ikarabellang ea metsi le likhoerekhoere tikolohong eo.

Kahoo, ho bohlokoa ho tseba sebopeho sa lihlahisoa tsohle pele o reka hobane arsenic e teng ha ho etsoa thepa e fapaneng e sebelisoang hae, haholo lik'hemik'hale le lisebelisoa tse phekotsoeng ka lintho tse bolokang.

3. Mokhoa oa ho qoba ho kopana le Moeta-pele

Moeta-pele ke tšepe e teng linthong tse ngata tse sebelisoang bophelong ba letsatsi le letsatsi, ka hona, ho kgothaletswa ho lekola sebopeho sa lintho pele o reka, haholoholo tse entsoeng ka PVC.

Ntle le moo, loto e ne e boetse e le tšepe e boima eo hangata e neng e sebelisoa ha ho etsoa lipente tsa lebota, ka hona, matlo a hahiloeng pele ho 1980 a ka ba le loto e ngata maboteng a bona. Kahoo, ho bohlokoa hore o tlose pente ea mofuta ona ebe u penta ntlo ka lipente tse ncha tse se nang tšepe tse boima.

Malebela a mang a bohlokoa haholo ho qoba tšilafalo ea loto ke ho qoba ho sebelisa metsi a pompo hang kamora ho bula pompo, 'me o lumelle metsi hore a phole ho fihlela a bata pele a noa kapa a sebelisa metsi ho pheha.

Lisebelisoa tse ling tse boima

Le ha tsena e le tšepe e boima haholo mesebetsing ea letsatsi le letsatsi, ho bohlokoa ho qoba ho kopana le mefuta e meng ea litšepe tse boima, joalo ka barium, cadmium kapa chromium, tse atisang ho ba teng indastering le libakeng tsa kaho, empa tse ka bakang bophelo bo tebileng mathata ha ho sa sebelisoe mehato e nepahetseng ea ts'ireletso.

Tšilafalo e etsahala hobane, leha, kamora ho kopana hanghang le boholo ba mefuta ena ea tšepe, ha ho na nts'etsopele ea matšoao, lintho tsena li bokellana 'meleng oa motho,' me li ka lebisa ho chefo ka litlamorao tse mpe, joalo ka ho hloleha ha liphio esita le mofetše.

Bona tsela ea tlholeho ea ho tlosa tse ling tsa litšepe tse boima haholo 'meleng.
