ʻOxalic Acid
He ʻano ʻakika organik, he huahana metabolic o nā meaola, binary acid, hoʻolaha nui ʻia i nā mea kanu, nā holoholona a me nā haʻani, a ma nā mea ola like ʻole e pāʻani i nā hana like ʻole.Ua ʻike ʻia ka waiwai o ka ʻakika oxalic i nā ʻano mea kanu ʻoi aku ma mua o 100, ʻoi aku ka spinach, amaranth, beet, purslane, kalo, ʻuala a me ka rhubarb.No ka mea hiki i ka oxalic acid ke hōʻemi i ka bioavailability o nā mea mineral, ua manaʻo ʻia he antagonist no ka absorption a me ka hoʻohana ʻana i nā mea mineral.ʻO kāna anhydride he carbon sesquioxide.

Polyacrylamide（Pam）
(PAM) he homopolymer o ka acrylamide a i ole he polymer copolymerized me kekahi mau monomers.ʻO Polyacrylamide (PAM) kekahi o nā polymers i hoʻohana nui ʻia i ka wai.Hoʻohana nui ʻia ka polyacrylamide (PAM) i ka hoʻohana ʻana i ka aila, hana pepa, mālama wai, textile, lāʻau lapaʻau, mahiʻai a me nā ʻoihana ʻē aʻe.Wahi a nā helu helu, hoʻohana ʻia ka 37% o ka nui o ka polyacrylamide (PAM) o ka honua no ka mālama ʻana i ka wai, 27% no ka ʻoihana ʻaila, a me 18% no ka ʻoihana pepa.

Hydrofluoric Acid (HF)
He wai hoʻonā wai ia o ke kinoea hydrogen fluoride, ʻo ia hoʻi he wai ʻākala, kala ʻole, puhi ʻana i ka wai corrosive me kahi ʻala ʻala ikaika.ʻO ka waika Hydrofluoric he waika nāwaliwali loa ia, he mea ʻino loa ia i ka metala, aniani a me nā mea i loko o ke silika.ʻO ka inhalation o ka mahu a i ʻole ka pili ʻana me ka ʻili hiki ke hana i nā kuni paʻakikī e hoʻōla.Hana ʻia ka hale hana i ka fluorite (ʻo ka mea nui ka calcium fluoride) a me ka sulfuric acid concentrated, pono e hoʻopaʻa ʻia i loko o kahi hue plastik a mālama ʻia ma kahi anuanu.
