ʻO ka Metallurgy ka ʻoihana nui loa, akā, e like me nā wahi o ka hoʻokele waiwai, he hopena maikaʻi ʻole i ke kaiapuni. I loko o nā makahiki, alakaʻi kēia hopena i ka haumia o ka wai, ka ea, ka lepo, e pili ana i ka huliau.
Nā hoʻokuʻu ea
Kuhi ʻia kahi pilikia nui i ka metallurgy i mea e komo ai nā mea ʻino a me nā hui ʻino i loko o ka ea. Hoʻokuʻu ʻia lākou i ka wā o ke ahi wahie a me ka hana ʻana o nā mea maka. Kaukaʻi ʻia i nā kikoʻī o ka hana ʻana, komo nā mea haumia i ka lewa:
- kalapona kalapona;
- aluminika;
- arsenic;
- hydrogen sulfide;
- mercury;
- antimony;
- luaipele;
- tin;
- nitrogen;
- kēpau, etc.
Hoʻomaopopo ka poʻe loea i kēlā me kēia makahiki, no ka hana o nā mea kanu metallurgical, ma ka liʻiliʻi he 100 miliona mau tona o ka sulfur dioxide i hoʻokuʻu ʻia i ka ea. Ke komo i ka lewa, hāʻule ia i ka honua i ke ʻano o ka ua acid, e hoʻohaumia i nā mea āpau: nā lāʻau, nā hale, nā alanui, ka lepo, nā kahawai, nā kai a me nā loko.
Wao wai hana
ʻO ka pilikia maoli o ka metallurgy ka haumia o nā kino wai me nā ʻenehana ʻoihana. ʻO ke kuhi ke hoʻohana ʻia nā kumuwaiwai wai i nā pae like ʻole o ka hana metallurgical. I loko o kēia mau kaʻina hana, piha ka wai me nā phenol a me nā waikawa, nā impurities nui a me nā cyanides, arsenic a me cresol. Ma mua o ka hoʻokuʻu ʻia ʻana o ia mau effluents i loko o nā kino o ka wai, hoʻomaʻemaʻe ʻole ʻia lākou, no laila holoi ʻia kēia "cocktail" o ka hoʻoliʻiliʻi kemika mai ka metallurgy i ka wahi wai o nā kūlanakauhale. Ma hope o kēlā, hoʻopiha ʻia ka wai me kēia mau hoʻohui, ʻaʻole hiki ke inu wale, akā hoʻohana ʻia no nā hana kūloko.
Nā hopena o ka haumiaola biosphere
ʻO ka hoʻohaumia kaiapuni e ka ʻoihana metallurgical, ʻo ka mea mua, alakaʻi i kahi hōʻino i ke olakino lehulehu. ʻO ka mea ʻoi loa o nā mea āpau ke kūlana o kēlā mau poʻe e hana ana ma ia ʻoihana. Hoʻolālā lākou i nā maʻi maʻi e alakaʻi pinepine ai i ke kīnā a me ka make. Eia kekahi, ʻo ka poʻe āpau e noho kokoke ana i nā hale hana, ke hele nei ka manawa, loaʻa i nā maʻi nui, no ka mea e hanu lākou i ka ea lepo a inu i ka wai maikaʻi maikaʻi ʻole, a me nā pesticides, nā metala kaumaha a me nā nitrates e komo i ke kino.
I mea e hōʻemi ai i ka pae o ka hopena maikaʻi ʻole o ka metallurgy ma ke kaiapuni, pono e hoʻomohala a hoʻohana i nā ʻenehana hou i palekana no ke kaiapuni. Minamina, ʻaʻole hoʻohana nā ʻoihana āpau i nā kānana hoʻomaʻemaʻe a me nā pono, ʻoiai he mea koi kēia i nā hana o kēlā me kēia ʻoihana metallurgical.
