I ke kaʻina hana o ka papa ʻaina seramika, hiki i nā metala koʻikoʻi e like me ke kēpau a me ka cadmium i loko o ka glaze a me nā kumu hoʻonaninani. Inā hoʻohana ʻia i loko o ka meaʻai, ʻoi aku ka nui o ka meaʻai waikawa, hiki iā ia ke hoʻoheheʻe i ke kēpau a me ka cadmium i loko o ka meaʻai a komo i ke kino o ke kanaka. ʻO ke alakaʻi a me ka cadmium nā mea metala kaumaha e komo maʻalahi i ke kahe koko a ʻaʻole hiki ke hoʻokuʻu ʻia mai ke kino. ʻO ka hoʻohana lōʻihi ʻana i ka meaʻai i loaʻa i ke kēpau a me ka cadmium hiki ke loaʻa ka hopena i ka ʻōnaehana pale kanaka, e alakaʻi ana i ka hiki ʻana mai o nā maʻi like ʻole. ʻO nā hōʻailona nui o ka cadmium poisoning he arteriosclerosis, renal atrophy, nephritis, etc. Eia kekahi, ua ʻike ʻia ka cadmium i nā hopena carcinogenic a me teratogenic. Hiki i ka Cadmium ke hoʻoulu i ke kiʻekiʻe a me ka maʻi cardiovascular a me ka cerebrovascular; Poino i nā iwi, ate a me nā puʻupaʻa, a hiki ke hōʻeha i ka renal. He ʻano ʻawaʻawa loa ke kēpau o ka hoʻohaumia metala kaumaha, hiki ke alakaʻi i ka lāʻau ʻawaʻawa ma hope o ke komo ʻana e ke kino kanaka. ʻO nā keiki i ʻike ʻia i ke alakaʻi no ka manawa lōʻihi e maʻalahi i ka lohi i ka hopena a me ka pōʻino ʻike. Hiki i ke alakaʻi ke komo i loko o ke kino o ke kanaka ke hoʻopōʻino pono i nā pūnaewele lolo, ʻoi aku ka nui o ka ʻōnaehana nerve o nā fetuses, hiki ke hoʻopilikia i ka naʻauao congenital i nā fetuses. Eia kekahi, aia ka pilikia o ka maʻi kanesa a me ka hoʻololi ʻana.
