Sephetho sa tlhahlobo se bonts'itse hore li-cookware tse ling tsa aluminiamo le koporo li ntša litekanyo tse kholo tsa loto (Pb) ho tsoa ho li-cookware tse sebelisoang ho pheha lijo. Loto e chefo bathong, ka hona, lijo tse nang le loto e ngata ha li bolokehe hore li ka jeoa. Naheng ea Amerika, FDA e lemositse khahlanong le tšebeliso ea lintho tse ling tsa ho pheha tse entsoeng ka aluminium, koporo le lialloi tsa aluminium tse hlahisoang ke likarolo tse ling tsa linaha tse nang le meputso e tlase le e bohareng (LMICs) tse nang le maemo le taolo e lekantsoeng ea boleng. Bopaki bo bontša hore lisebelisoa tsa tšepe tse tloaelehileng tse tsoang lefats'eng lohle li ka 'na tsa e-na le tekanyo e phahameng ea loto. Fellows, KM et al (2024) ba ile ba lekola li-cookware tsa aluminium, lintho tsa koporo le lintho tsa tšepe tse se nang tšepe tse sebelisoang ho pheha 'me ba fumana hore lihlahisoa tse ngata tsa aluminium le koporo li na le likarolo tse fetang 100 ho milione (ppm) ea loto. Tlas'a maemo a etsisoang, ba bangata ba leached lead (Pb) ba feta meeli ea lijo tse khothaletsoang. Phuputso ea morao-rao e entsoeng ke Binkhorst G., et al (2025) e ile ea etsa lipatlisiso tsa ho pepeseha ha lead lead ho tsoa lipitseng tsa ho pheha tsa aluminium linaheng tse nang le moputso o tlase le o bohareng (LMICs) mme ea fumana hore kakaretso ea loto ka har'a lipitsa tsa ho pheha e ne e le 1600 ppm le kakaretso ea loto e ka bulehang e ne e batla e lekana. Ena ke taba ea bohlokoa ea bophelo bo botle ba sechaba hobane li-cookware tse joalo li sebelisoa haholo linaheng tse ngata ho pota lefatše.
FDA e lemositse khahlanong le tšebeliso ea lihlahisoa tse ling tse tsoang kantle ho naha tse entsoeng ka aluminium, koporo le lialloi tsa aluminium ka mor'a hore tlhahlobo e senole ho tsoa ha maemo a bohlokoa a lead (Pb) lijong ha li sebelisoa ho pheha, ka hona ho etsa hore lijo li se bolokehe. Ho fanoe ka lethathamo la lihlahisoa tse joalo tsa cookware, 'me basebelisi ba eletsoa ho lahla lihlahisoa tse joalo. Ba nang le seabo khoebong ea phepelo ea lihlahisoa tse joalo ba eletsoa ho khaotsa ho sebetsana le lihlahisoa tse joalo.
Loto e kotsi ho batho 'me e ka ama batho ba lilemo leha e le life. Esita le tekanyo e tlaase ea ho pepesehela loto e ka baka mathata a tebileng a bophelo bo botle, haholo-holo baneng le masea a ka pōpelong. Bana le masea ba kotsing ea ho hlaseloa ke chefo ea loto.
Hoa tsebahala hore metalware ea setso e tsoang lefats'eng ka bophara e ka ba le maemo a holimo a lebisang, e ka kenang lijong le linong ha e sebelisoa ho pheha, ho fana kapa ho boloka lijo le lino. Selemong se fetileng, ka Phupu 2024, tlhahlobo ea lead lead ea mali New York City e ile ea supa mosali oa moimana le litho tse peli tsa lelapa tse nang le li-lead tsa mali tse fetang 3.5 µg/dL. Ba ne ba sebelisitse lisebelisoa tsa tšepe tsa koporo le tsa koporo ho lokisa le ho fana ka lijo le lino.
Bakeng sa ho tseba mohloli oa ho pepeseha ha lead, Fellows, KM et al (2024) ba ile ba lekola li-cookware tsa aluminium, lintho tsa koporo le lintho tsa tšepe tse se nang tšepe tse sebelisoang ho pheha. Ho ile ha fumanoa hore lihlahisoa tse ngata tsa aluminium tse phehang li na le likarolo tse fetang 100 ho milione (ppm) ea loto. Tlas'a maemo a etsisoang a ho pheha le ho boloka, lead lead e ngata (Pb) e fetang tekanyo ea lijo e khothaletsoang. Lipitsa tsa koporo le tsona li bontšitse litholoana tse ts'oanang tse fanang ka maemo a holimo a loto. Thutong ena, hoa thahasellisa hore li-cookware tsa tšepe tse sa hloekang li na le loto e nyane haholo ha li bapisoa le lintho tsa aluminium le koporo.
Hoa tsebahala hore li-cookware tsa tšepe tse hlahisoang ke likarolo tse ling tsa linaha tse nang le meputso e tlase le e bohareng (LMICs) tse nang le maemo a lekanyelitsoeng a boleng le taolo li na le lintlha tse ngata tsa loto. Phuputso ea morao-rao e entsoeng ke Binkhorst G., et al (2025) e batlisitse ho pepeseha ha lead lead ho tsoa lipitseng tsa ho pheha tsa aluminium linaheng tse tlase le tse bohareng. Tlhahlobo ea lipitsa tse ncha tsa aluminium tse 113 tse tsoang ho 25 LMICs e senotse hore palo ea loto e felletseng ka har'a lipitsa e tloha ho <5 ppm ho isa ho hoo e ka bang 16,000 ppm, e leng karolelano ea 1600 ppm, e nang le palo e phahameng ka ho fetisisa ea lead lead lipitseng tse tsoang Vietnam, Pakistan, Indonesia le India. Likarolo tsa loto tse ka fumanehang li ne li tloha ho <1–2900 μg/L ka karolelano ea 100 μg/L ka mor’a ho belisa 4 % acetic acid bakeng sa 2 h.
