Pehea e pale ai i ka hoʻowahāwahā i nā mea kaumaha

Anter

• 1. Pehea e pale ai i ka launa ʻana me Mercury
• 2. Pehea e pale ai i ka launa pū ʻana me Arsenic
• 3. Pehea e pale ai i ka launa pū ʻana me Lead
• Nā metala kaumaha ʻē aʻe

I mea e hōʻalo ai i nā mea hoʻowahāwahā ʻia i hiki ke alakaʻi ʻia i nā maʻi koʻikoʻi e like me ka hōʻino ʻana o ka puʻuwai a i ʻole ke kanesa, he mea nui e hōʻemi i ka pilina me nā ʻano metala kaumaha e weliweli i ke olakino.

ʻO Mercury, arsenic a me kēpau nā ʻano i hoʻohana nui ʻia i ka hoʻohui ʻana o nā mea like ʻole o ko mākou ola o kēlā me kēia lā, e like me nā kukui, nā pena a me nā meaʻai a, no laila, ʻo ia ka mea hiki ke maʻalahi i ka lāʻau make.

E ʻike i nā ʻōuli nui o ka hoʻohaumia kaumaha.

I mea e hōʻalo ai i nā pilikia olakino āpau he mea nui e ʻike i nā mea i loaʻa ka nui o kēia mau metala i mea e ʻike ai i nā mea e loli ai hoʻopau ʻia hoʻi mai ka pilina o kēlā me kēia lā.

1. Pehea e pale ai i ka launa ʻana me Mercury

ʻO kekahi mau ala e hōʻalo ai i ka hōʻike kūpono ʻole i ka mercury me:

• Hōʻalo i ka ʻai ʻana i ka iʻa me ka nui o ka mercury pinepine, e like me ka mackerel, ka iʻa pahi kaua a i ʻole marlin, no ka laʻana, e hāʻawi ana i ka makemake i nā salemona, nā sardine a i ʻole nā ​​heleuma;
• ʻAʻohe o nā mea me ka mercury ma ka home i kāna ʻano, e like me ka pena, nā paila i hoʻohana ʻia, nā kukui i hoʻohana ʻia a i ʻole nā ​​thermometers mercury;
• Hōʻalo i ka haki ʻana i nā mea me ka mercury wai, e like me nā kukui fluorescent a i ʻole thermometers;

Eia hou, i nā hihia o nā ana a me nā lāʻau lapaʻau ʻē aʻe, aʻoaʻo ʻia hoʻi ʻaʻole e hoʻohana i ka hoʻopiha niho me ka mercury, e hāʻawi ana i ka makemake i nā hoʻopiha resin, no ka laʻana.

2. Pehea e pale ai i ka launa pū ʻana me Arsenic

I mea e hōʻalo ai i ka haumia arsenic, he mea nui ia:

• ʻO ka hemo ʻana i nā lāʻau i mālama ʻia me nā preservatives me CCA a i ʻole ACZA a noi i kahi kapa komo o ka wepa a i ʻole arsenic-free pena e hoʻemi ai i ka pilina;
• Mai hoʻohana i nā mea hoʻomomona a me nā mea lāʻau me ka monosodium methanearsonate (MSMA), calcium methanearsonate a i ʻole cacodylic acid;
• Hōʻalo i ka lawe ʻana i ka lāʻau me arsenic, ke noi nei i ke kauka e pili ana i ka hoʻohui o ka lāʻau e hoʻohana nei;
• Mālama i ka wai maikaʻi a ua hoʻāʻo ʻia e ka ʻoihana kuleana wai a me ka hoʻowai wai i kēia wahi.

No laila, he mea nui e makaʻala i ka hoʻohui ʻana o nā huahana āpau ma mua o ke kūʻai ʻana no ka mea aia ka arsenic i ka hui ʻana o nā mea like ʻole i hoʻohana ʻia ma ka home, ʻo ka hapanui nā kemika a me nā mea i mālama ʻia me nā preservatives.

3. Pehea e pale ai i ka launa pū ʻana me Lead

ʻO kēpau kahi mea hao i loaʻa i nā mea he nui i hoʻohana ʻia i ke ola o kēlā me kēia lā a, no laila, koi ʻia e nānā i ka hoʻohui o nā mea ma mua o ke kūʻai ʻana, ʻo ia hoʻi nā mea i hana ʻia e PVC.

Hoʻohui ʻia, he kēpau kaumaha kekahi kēpau i hoʻohana pinepine ʻia i ka hana ʻia ʻana o nā pena paia a, no laila, ʻo nā hale i kūkulu ʻia ma mua o ka makahiki 1980 ke piha ka nui o ke kēpau ma kā lākou paia. No laila, he ʻōlelo aʻoaʻo e hemo i kēia ʻano pena a pena i ka hale me nā pena hou me ka ʻole o nā metala kaumaha.

ʻO kahi kihi nui ʻē aʻe e hōʻalo ai i ka haumia kēpau e hōʻalo i ka hoʻohana ʻana i ka wai kaomi ma hope koke o ka wehe ʻana i ka piula, a e hoʻomalule ka wai i kona wahi anuanu ma mua o ka inu ʻana a hoʻohana ʻana paha i ka wai no ka kuke ʻana.

Nā metala kaumaha ʻē aʻe

ʻOiai ʻo kēia nā metala kaumaha nui loa i nā hana o kēlā me kēia lā, he mea nui e hōʻole ʻole i ka launa pū ʻana me nā ʻano metala kaumaha, e like me barium, cadmium a chromium paha, i ʻoi aku ka pinepine i nā ʻoihana a me nā kahua kūkulu, akā hiki nō hoʻi ke kumu i ke olakino koʻikoʻi. nā pilikia. ke hoʻohana ʻole ʻia nā hana palekana kūpono.

Kū ka haumia no ka mea, ʻoiai, ma hope o ka pili koke ʻana me ka hapa nui o kēia mau ʻano metala, ʻaʻohe ulu o nā ʻōuli, hōʻiliʻili kēia mau mea i loko o ke kino o ke kanaka, a hiki ke alakaʻi i ka manawa i ka lāʻau make me nā hopena koʻikoʻi, e like me ka hōʻino kīwī. A ʻoiai maʻi ʻaʻai.

E ʻike i kahi ala kūlohelohe e hoʻopau ai i kekahi o nā metala kaumaha i loko o ke kino.
