I te wa e mahia ana te plywood, ka whakamahia noa nga whakapiri i runga i te formaldehyde{0}}, no reira ka tukuna e te hua kua oti te formaldehyde kore utu ki nga nekehanga rereke. Ki te nui ake te ihirangi formaldehyde kore utu ki tetahi rohe, ka pa ki te hauora o te tangata. He tukanga uaua te whakamatautau i te tuku formaldehyde o te plywood. Ka taea te whakamahi i te tikanga e whai ake nei hei whakatau i te whakatau tuatahi mo te tuku formaldehyde o te plywood. Tuatahi, whakahiatohia te papapa ki roto i tetahi ruma iti, kati nga kuaha me nga matapihi, ka tirotirohia i muri i te waa. Mena karekau he haunga, e tohu ana he iti te tuku formaldehyde o te plywood, a, kaore e pa ki te hauora o te tangata; ki te kaha te haunga, ki te haea ranei, he tohu tera pea ka nui te tuku formaldehyde o te plywood.
Mo te take formaldehyde o te plywood, he pore te rahi o ona pore o roto i waenga i te 0.27 me te 0.98 nanometer, ka whakaritea ki te tauira tioata. Kei a ia ano nga ahuatanga hiko ngoikore. Ko te formaldehyde, te haukini, te benzene, te toluene, me te xylene nga ngota ngota he diameter kei waenganui i te 0.4 me te 0.62 nanometer he ngota ngota polar, he tohu mo te whakangao hau kino penei i te formaldehyde, benzene, me te TVOC, na reira ka puta te hua o te purea hau o roto. Ka taea te whakauru me te whakapohehe i te formaldehyde, ka taea te whakamahi ano i muri i te pa ki te ra.
