1. ʻO ka ʻoihana kemika maikaʻi no ka ʻoihana hana a he kiʻekiʻe kiʻekiʻe o ka pili ʻoihana me nā ʻoihana ʻē aʻe.
ʻO nāʻoihana e pili kokoke ana i kaʻoihana kemika maikaʻi ka mea nui: ka mahiʻai, ka lole lole, ka hana, ka pepa pepa, ka meaʻai meaʻai, ka hana kemika i kēlā me kēia lā, nā lako uila, a me nā mea'ē aʻe.
ʻO ka uka o ka ʻoihana kemika maikaʻi ʻo ia ka hana nui ʻana i nā mea kumu kemika; i ka manawa like, ʻo nā huahana i hāʻawi ʻia e ka ʻoihana kemika maikaʻi nā kumu kumu no nā ʻoihana ʻē aʻe he nui, e like me ka mahiʻai, kūkulu hale, textiles, pharmaceuticals a me nā ʻoihana koʻikoʻi ʻē aʻe. ʻO ka hoʻomohala ʻana i ka mahiʻai, kūkulu, textile, pharmaceutical, electronics a me nā ʻoihana ʻē aʻe e pili ana e hāʻawi i nā manawa hoʻomohala no ka hoʻomohala ʻana i ka ʻoihana kemika maikaʻi; i ka manawa like, ʻo ka hoʻomohala ʻana i ka ʻoihana kemika maikaʻi e hāpai pū i ka hoʻomohala ʻana i nā ʻoihana i luna.
2. Aia kekahi mau hi'ohi'ona o ka 'oihana kemika maika'i
ʻOi aku ka nui o ka hana ʻana o nā ʻoihana hana kemika maikaʻi ma mua o 100,000 tons. I ka hapa lua o ke kenekulia 20, ua hōʻike ʻia nā ʻoihana hana kemika maikaʻi e ʻAmelika Hui Pū ʻIa a me Iapana, e hōʻike ana i nā hiʻohiʻona o ka nui a me ka loea, i mea e hōʻemi mau ai i nā kumukūʻai hana. I kēia manawa, haʻahaʻa loa ka ʻike o ka ʻoihana kemika maikaʻi o koʻu ʻāina, me ka hapa nui o nā ʻoihana liʻiliʻi, ʻoiai ʻo ka hapa o nā ʻoihana waena a me nā ʻoihana nui, ʻoi aku ka nui o nā ʻoihana nui.
3. ʻO ka ʻoihana kemika maikaʻi he ʻoihana me nā hoʻokuʻu kiʻekiʻe o nā mea haumia ʻoihana
Wahi a ka 2012 Environmental Statistics Annual Report, ʻo ka hoʻokuʻu ʻia ʻana o ka wai ʻino o ka ʻoihana kemika he 16.3% o ka hoʻokuʻu ʻia ʻana o ka wai ʻino o ka ʻāina, ka lua; ʻO ka hoʻokuʻu ʻia ʻana o ke kinoea hoʻopau ʻia he 6% o ka hoʻokuʻu ʻia ʻana o ka ʻoihana ʻāina, ka pae ʻehā; nā ʻōpala paʻa paʻa ʻO ia ka 5% o nā ʻōpala paʻa paʻa o ka ʻāina, ka pae ʻelima; He 11.7% ka nui o ka hoʻokuʻu ʻana o COD i ka ʻāina, ka helu ʻekolu.
4. Nā hiʻohiʻona manawa o ka ʻoihana
ʻO nā ʻoihana o lalo e kū pono ana i ka ʻoihana kemika maikaʻi loa e pili ana i nā plasticizer kaiapuni, nā uhi pauka, nā mea insulating, nā mea mālama wela wela a me nā ʻoihana ʻē aʻe. Hoʻohana ʻia nā huahana hope i nā huahana plastik like ʻole, nā mea kūkulu hale, nā mea hoʻopihapiha, nā mea pono hale, nā mīkini kaʻa, etc. ʻo ka macroeconomic, e hōʻike ana i kekahi mau fluctuations i ka hoʻololi ʻana o ke kūlana waiwai holoʻokoʻa. ʻO ka pōʻaiapuni o ka ʻoihana e like me ka pōʻai o ka hana macroeconomic holoʻokoʻa.
5. Nā hiʻohiʻona kūloko o ka ʻoihana
Mai ka hiʻohiʻona o ka māhele ʻāina o nā ʻoihana ʻoihana kemika maikaʻi o koʻu ʻāina, ʻike ʻia ke ʻano o ka ʻāpana o nā ʻoihana i ka ʻoihana kemika maikaʻi, me ka helu ʻana o East China no ka hapa nui loa a ʻo North China ka helu lua.
6. Nā hiʻohiʻona kau o ka ʻoihana
ʻO nā māhele noi lalo o ka ʻoihana kemika maikaʻi he ʻano ākea, a ʻaʻohe hiʻohiʻona ʻike ʻia o ke kau ma ka laulā.
