Ka taea e ngā hangarau kimi matatau pēnei i te chromatography wai mahi teitei (HPLC) te chromatography hau (GC) rānei te ine tika i te ihirangi formaldehyde; mā te tauira auau me ngā mahi maimoatanga whai muri tino ka taea te whakarite kia pumau te kounga o te hua.
Ko te whakangungu me te whakahaere kaimahi ngā mea matua: ko te whakangungu i ngā kaimahi mō ngā tūponotanga me te tiaki i te formaldehyde, me te whakangungu me te aromatawai i ngā tikanga whakahaere paerewa, ehara i te mea ka taea te whakaiti i te nui o te formaldehyde, engari ka taea hoki te whakarite i te hauora me te haumaru o ngā kaimahi. Whai muri i te whakatinanatanga o te whakangungu tikanga whakahaere paerewa, ka taea te whakaiti i te nui o te formaldehyde o ngā hua mā te 15%, ā, ka taea te whakanui ake i te pai o te whakaputa mā te 10%.
7.2 Ngā Taunakitanga
Whakapai tonu i te kounga o ngā rauemi mata: Me mahi tahi ngā umanga me ngā kaiwhakarato ki te whakawhanake tahi i ngā rauemi mata silicone me ngā tāpiringa iti-formaldehyde, kāore rānei he formaldehyde, hei whakakore i te whakaurunga mai o te formaldehyde mai i te pūtake. I taua wā anō, me whakapakari ake te aromatawai me te arotake i ngā kaiwhakarato rauemi mata kia mōhio ai kei te tutuki tonu i ngā rauemi mata kua hokona ngā whakaritenga tiaki taiao me te haumaru.
Whakahohonu ake i te arotautanga o ngā tukanga whakaputa: Me tūhura tonu ngā umanga me te whakamahi i ngā hangarau tukanga whakaputa matatau ake hei arotau ake i ngā tawhā tukanga whakamomona me te whakapūtanga. Hei tauira, whakauruhia ngā taputapu whakaputa atamai me ngā pūnaha whakahaere hei whakatutuki i te aroturukitanga tika me te whakarerekētanga aunoa o te tukanga whakaputa, kia pai ake ai te whakaiti i te whakaputanga o te formaldehyde.
Whakakahangia te whakahaere taiao me ngā taputapu: Me whakahou tonu ngā umanga i ngā pūnaha hauhautanga o te awheawhe me ngā taputapu whakaputa kia pai ai te āhua o te hauhautanga me te horoi me te tiaki i ngā taputapu. I taua wā anō, me whakatū he tikanga whakahou me te whakapai ake i ngā taputapu, me whakakore i ngā taputapu tawhito he nui te tūponotanga o te tukunga formaldehyde, me te whakauru i ngā taputapu whakaputa hou he iti te tukunga formaldehyde.
Whakakaha ake i te tirotiro me te aroturuki kounga: Me whakapai ake ngā umanga i ngā paerewa me ngā tikanga tauira mō te kimi formaldehyde, me whakanui ake i te auau me te rahi o te tauira, me te whakarite kia tino whakahaerehia te nui o te formaldehyde o ngā hua i roto i te awhe haumaru. I taua wā anō, me whakapakari ake te tātari me te whakamahi i ngā raraunga tauira, me te kimi i ngā raru kounga pea i te wā tika, me te mahi i ngā mahi ārai me te whakatikatika whai hua.
Kia aro ki te whakangungu me te whakahaere kaimahi: Me whakauru e ngā umanga te whakangungu kaimahi ki roto i ngā mahere whanaketanga roa, me whakarite i ngā whakangungu mō te tūponotanga me te tiaki i te formaldehyde me te whakangungu tukanga whakahaere paerewa, me te whakapai ake i te mōhiotanga taiao me ngā pūkenga whakahaere o ngā kaimahi. I taua wā anō, me whakatū he tikanga tirotiro me te urupare katoa hei akiaki i ngā kaimahi ki te whai wāhi kaha ki ngā mahi whakapai ake i te kounga me te hanga i tētahi āhuarangi pai mō te whai wāhi katoa me te whakahaere tahi.
Hei whakarāpopototanga, mā roto i ngā mahi whānui pēnei i te whakahaere rauemi mata, te arotau i ngā tukanga whakaputa, te whakahaere taiao me ngā taputapu, te tirotiro me te aroturuki kounga, te whakangungu me te whakahaere kaimahi, ka taea te whakaiti i te nui o te formaldehyde i roto i te tukanga whakaputa o ngā papa hope silicone, ka taea te whakamana i te kounga me te haumaru o ngā hua, ka taea te tiaki i te hauora o ngā kaihoko, ā, ka whai wāhi atu hoki ki te whanaketanga pumau o te hinonga.
