Ka taea e ngā Ārai Whakamārama Whatu te mimiti i te mārama UV me te whakaata i roto i te mārama kikorangi me te mārama kikorangi e kitea ana, e kore e ārai noa i te mārama kōwhai iti i runga i te papanga engari ka whakanui ake hoki i tōna kanapa. Nō reira, mā te tāpiri i te hopi horoi OBA ka mā ake, ka kanapa ake te āhua o ngā mea kua horoia.
Mō ngā hua anō, mā te tāpiri i te OBA ka tino whakapai ake i te mā me te kanapa o te hopi horoi kakahu, te hopi, me ētahi atu, ka whakapai ake hoki i tetō rātou āhua, ā, kia ātaahua ake ai, kia ma ake ai hoki ngā hua.
Koinei te tauira noa o te hopi horoi kakahu:
| Ihirangi | Te ōwehenga |
| LAS | 15-20% |
| Na2CO3 | 20-30% |
| Na2O·nSiO2 | 5-10% |
| 2Na2CO3·3H2O | 5-10% |
| Whakamārama Whatu | 0.1-0.5% |
| Kakara Kakara | 0.1-0.3% |
| whākōkī | 0.5-1% |
Te rama whatuCBS-Xhe rite tonu te utu e tukuna ana e tā mātou kamupene ki tētahi waitohu rongonui o Ūropi, engari he iti iho te utu. E whakamahia ana i ngā mea utu nui akewai hopi horoi kakahu, ā, ka taea hoki te whakamahi mō te mā, te tae rāneihopi ataahuaHei whakaaro ki te utu, he iti ake te utu e tukuna ana e mātoungā hua mō te nuingapaura hopi horoi.
Mō te haumaru o te OBA, he maha ngā rangahau paitini o te motu me te ao kua whakaatu kāore he pānga mate pukupuku, he pānga mutagenic, he pānga teratogenic rānei o te OBA. Hei tauira, kua whakahaerehia e ngā whakahaere pēnei i te Manatū Taiao o Tiamana, te Rōpū Hopi Hopi o te Kotahitanga o Ūropi (AISE), me te Rōpū Ahumahi Hopi me te Hopi o Hapani (JSDA) he aromatawai whānui mō te OBA, e whakaū ana kāore he kino ki te tangata me te taiao i te horopeta kua whakaritea.
Nō reira, kāore he rangahau whai mana e whakaatu ana he mate pukupuku te OBA. Ahakoa e kī ana ētahi ka pāngia te kiri e te mumura, e te mate pāwera rānei, kāore ēnei tauhohenga e pā ana ki te mate pukupuku, ā, he iti noa iho te auau.
