Ka hoʻololi ʻana o ka glyphosate a me kāna AMPA hoʻohaʻahaʻa i ka wai i luna ma o nā ʻōnaehana sewerage kūlanakauhale

Ua hoʻokō ʻia kahi noiʻi o ka hoʻoili ʻana o ka glyphosate a me ka aminomethyl phosphonic acid (AMPA) ma ka wai o Orge (Farani) i ka makahiki 2007 a me 2008. Ua hōʻiliʻili ʻia nā mea hoʻohālike wai i loko o ka wai ʻili, ka ʻōpala wai ʻino, ka ʻino a me ka mea kanu hoʻomaʻemaʻe wai (WWTP). ʻO kēia mau molekala ʻelua ka mea i ʻike pinepine ʻia i loko o nā muliwai a ʻoi aku ma mua o nā ʻano koina maʻamau o ʻEulopa o 0.1 μg L.^-1 no ka inu wai. ʻO ka glyphosate makahiki i manaʻo ʻia he 1.9 kg makahiki^-1 uka (wahi mahiai) a me 179.5 kg makahiki^-1 ma ka puka hoʻoheheʻe ʻana (kaona). Hōʻike kēia hopena i ka hoʻohaumia ʻana o kēia kīʻaha e ka glyphosate mai ke kūlanakauhale kumu (nā noi alanui a me ke kaʻaahi). Ua hele pinepine ʻo Glyphosate i ka wai ʻili ma o ka ʻino ʻino i ka wā o ka ua. Ua ʻike ʻia nā manaʻo kiʻekiʻe loa i ka ʻino ma hope o kahi hanana ua (75-90 μg L.^-1). Hōʻike ka manaʻo kiʻekiʻe o ka glyphosate i ka wai ʻili i ka wā o ka ua i ka hopena o ka holo ʻana o ke kūlanakauhale. Ua ʻike mau ʻia ka AMPA i ka ʻōnaehana sewerage. Ua hiki kēia mole i ka wai ʻili ma o ka luawai WWTP a me ka wai ʻino. He mea liʻiliʻi nā ʻano like ʻole o ka AMPA i ka wā hydrological i hoʻohālikelike ʻia me nā ʻano hoʻololi glyphosate. Hōʻike kā mākou aʻo ʻana he ʻokoʻa ka AMPA a me ka glyphosate i ke kūlanakauhale. I ka wā maloʻo, ʻo ka detergent degradation ke kumu nui o ka AMPA i ka wai ʻōpala.
