He aha tāu e mōhio ai mō te waro whakahohe?
He aha te tikanga o te waro whakahohe?
He rauemi taiao tukatuka te waro whakahohe, he nui te waro kei roto. Hei tauira, he pai rawa te waro, te rakau, te kokonati rānei mō tēnei. He nui te porosity o te hua ka puta, ā, ka taea te mimiti i ngā ngota o ngā poke me te hopu i a rātou, ā, ka purea te hau, ngā hau me ngā wai.
He aha ngā āhua ka taea te whakarato i te waro whakahohe?
Ka taea te hanga waro whakahohe hei hanga arumoni i roto i ngā āhua porotaka, porotaka me te paura. He rerekē ngā rahi kua tautuhia mō ngā whakamahinga rerekē. Hei tauira, i roto i te maimoatanga hau, hau rānei, ka kawemaihia te here ki te rere, nō reira ka whakamahia ngā matūriki taratara hei whakaiti i te ngaronga pēhanga. I roto i te maimoatanga wai, i te wā e puhoi ake ana te tukanga tango, ka whakamahia ngā matūriki angiangi hei whakapai ake i te tere, te nekeneke rānei, o te tukanga purenga.
Me pēhea te mahi a te waro whakahohe?
Ka mahi te waro whakahohe mā te tukanga mimiti. He kukume tēnei o te ngota ki te mata whānui o roto o te waro e ngā kaha ngoikore, e mōhiotia ana ko ngā kaha o Rānana. Ka mau tonu te ngota ki tōna tūranga, ā, kāore e taea te tango, ki te kore e rerekē ngā āhuatanga o te tukanga, hei tauira, te whakamahana, te pēhanga rānei. He whai hua tēnei nā te mea ka taea te whakamahi i te waro whakahohe hei whakawhāiti i ngā rauemi ki tōna mata ka taea te tango i muri mai ka whakahokia mai. Ko te whakamahinga o te waro whakahohe mō te whakaora koura tētahi tauira noa o tēnei.
I ētahi wā, ka tukatukahia te waro whakahohe ki te matū hei tango i ngā poke, ā, i tēnei wā, kāore te matū i tauhohehia e whakahokia mai.
Kāore hoki te mata o te waro whakahohe i te tino mangere, ā, he maha ngā tukanga whakaterenga ka taea te whakatutuki mā te whakamahi me te whakamahi i te horahanga mata o roto e wātea ana.
He aha te waro whakahohe i runga i ngā tono?
He maha ngā whakamahinga o ngā waro whakahohe, mai i te tātari ki te purenga, me tua atu.
I ngā tau tata nei, kua piki ake te kaha me te auau o ngā raruraru reka me te kakara i roto i te wai inu puta noa i te ao. Haunga te raruraru ataahua mō te kaihoko, ka puta ake hoki i tēnei te koretake mō te kounga me te haumaru o te wai. Ko ngā matū e takea ana ngā raruraru reka me te kakara ka puta mai i te tangata (ngā tukunga ahumahi, ā-tāone rānei) i ahu mai i te koiora, i te tangata rānei. I tēnei take whakamutunga, ka puta mai i ngā rauropi moroiti pēnei i te cyanobacteria.
Ko ngā matū e rua e tino kitea ana ko te geosmin me te 2-methylisoborneol (MIB). Ko te Geosmin, he kakara oneone tōna, ka hangaia i te nuinga o te wā e ngā planktonic cyanobacteria (e iri ana i roto i te wai). Ko te MIB, he kakara haunga, ka hangaia i roto i te biofilm e whanake ana i runga i ngā toka, ngā tipu wai me te paru. Ka kitea ēnei matū e ngā pūtau kakara tangata i ngā kukū tino iti, ahakoa i roto i te whānuitanga o ētahi wāhanga ia tiriona (ppt, ng/l rānei).
Kāore e taea e ngā tikanga maimoatanga wai tuku iho te tango i te MIB me te geosmin ki raro iho i ō rāua paepae reka me te haunga, ā, ka whakamahia te waro whakahohe mō tēnei mahi. Ko tētahi tikanga whakamahi noa ko te paura waro whakahohe (PAC), e ringihia ana ki roto i te awa wai i ia wā hei whakahaere i ngā take reka me te haunga.
