ʻO ka Moana Baletika kahi wahi kai i uka o Eurasia aia ma ka ʻākau o ʻEulopa a no ka Basin ʻAtelanika. Hoʻololi ka wai me ka Moana Honua ma o nā kahawai Kattegat a me Skagerrak. Ma mua o ʻelua haneli mau kahawai e kahe ana i ke kai. Na lākou e hāpai i ka wai haumia e kahe ana i kahi o ka wai. Ua hōʻino nui nā mea pollutants i ka hiki ke hoʻomaʻemaʻe iā ʻoe iho i ke kai.
He aha nā mea e haumia ai ke kai Baletika?
Aia kekahi mau pūʻulu o nā mea weliweli e hōʻino i ka Baletika. ʻO ka mea mua, eia nā nitrogen a me nā phosphore, nā ʻōpala mai ka mahiʻai, nā ʻoihana ʻenehana a loaʻa i loko o nā wai neoneo o nā kūlanakauhale. Hoʻomaʻamaʻa ʻia kēia mau mea i ka wai wale nō, hoʻopuka lākou i ka hydrogen sulfide, e hiki ai i ka make o nā holoholona kai a me nā mea kanu.
ʻO ka hui ʻelua o nā mea weliweli he metala kaumaha. Hāʻule pū ka hapalua o kēia mau mea me ka ua lewa, a me kahi ʻāpana - me ka wai wai neoneo. Hoʻokumu kēia mau mea i ka maʻi a me ka make no ka nui o ke ola kai.
ʻAʻole malihini ka hui ʻekolu o nā mea haumia i nā kai a me nā moana he nui - ka ninini o ka aila. ʻO kahi kiʻi ʻoniʻoni mai nā aila i hana ma luna o ka wai, ʻaʻole ʻae e hele i loko o ka oxygen. Pepehi kēia i nā mea kanu moana āpau a me nā holoholona ma loko o ka radius o ka aila i paheʻe.
ʻO nā ala nui o ka haumia o ke kai Baletika:
- hoʻokuʻu pololei i ke kai;
- paipu;
- wai kahawai kahawai;
- nā ulia ma nā wahi uila uila;
- ka hana ana o na moku;
- ea.
He aha nā haumia ʻē aʻe e hana nei ma ke kai Baletika?
Ma waho aʻe o ka hoʻohaunaele ʻenehana a me nā kaona, aia kekahi ʻoi aku ka nui o nā kumu haumia i ka Baltic. ʻO ka mea mua, he kemika. No laila ma hope o ke Kaua Honua ʻElua, ma kahi o ʻekolu tone o nā mea kaua kemika i hāʻule i loko o ka wai o kēia wahi wai. ʻAʻole i loko wale nā mea ʻino, akā nā mea ʻawahia make loa i ke ola kai.
ʻO kekahi pilikia ka hoʻohaumia radioactive. Komo nā radionuclides he nui i ke kai, i hoʻolei ʻia mai nā ʻoihana like ʻole ma ʻEulopa Komohana. Eia hou, ma hope o ka ulia pōpilikia ʻo Chernobyl, ua komo ka nui o nā mea radioactive i ka wahi o ka wai, kahi i hoʻopōʻino ʻia ke kaiaolaola.
Ua alakaʻi kēia mau mea haumia āpau i ka ʻoiaʻiʻo ʻaʻohe oxygen ma ka hapakolu o ka ʻili o ke kai, kahi i hāpai ai i nā phenomena e like me "nā wahi make" me kahi kiʻekiʻe o ka hoʻokumu ʻana o nā mea ʻona. A i kēlā mau ʻano ʻaʻole hiki i kahi microorganism hoʻokahi ke noho.
