ʻO ka Nitrates nā pūhui kūlohelohe i ka pōʻai nitrogen ma waena o ka ea, ka wai, a me nā mea ola. ʻO nā molekala NO3 he palekana no ke kanaka, ua maʻalahi ke hana ʻia i loko o ko mākou kino, he ʻāpana o ka saliva, hoʻololi ʻia i loko o ke ake, a hoʻokuʻu ʻia i loko o ka mimi. ʻO nā kumu nui o ka nitrates no ke kanaka he mau mea kanu i hoʻonui maoli ʻia e like me ka beets, spinach, arugula, celery, a me nā lau ʻōmaʻomaʻo ʻē aʻe. I ka manawa i loko o ke kino kanaka, ua hoʻololi ʻia nā nitrates i nitrite, NO2-, ma lalo o ka mana o ka bacteria waha, a laila lilo ia i kumu no ka hoʻokumu ʻana o ka nitric oxide.
ʻO NO ka molekele hōʻailona koʻikoʻi i loko o ke kino. Hoʻomaha ia i nā ʻiʻo maʻemaʻe o ka paia vascular, kahi e hoʻohaʻahaʻa ai i ke koko a hoʻomaikaʻi i ke koko. Ua hōʻike nā haʻawina i ka hopena maikaʻi o ka nitric oxide i ka lōʻihi a me ka ikaika o ka hana kino, ka hana ʻāʻī, a me nā hana ʻelemakule.
Ma ke alo o nā amino acids a me nā mahana kiʻekiʻe, hiki i nā nitrites ke hana i nā nitrosamines, nā mea i hoʻokaʻawale ʻia e WHO he carcinogens. Hoʻokumu ʻia ia mau kūlana i ka ʻiʻo i ka wā e hoʻomaʻamaʻa ʻia me ka puhi ʻana, ka ʻai ʻana, a me ka hana ʻana i nā sausages, ke hoʻohui ʻia nā nitrates ma ke ʻano he preservatives (nā nitrates e pale i ka ulu ʻana o nā bacteria pathogenic, me ka pathogen botulism) a me ka hoʻomaikaʻi ʻana i ka helehelena (ʻulaʻula. -ʻulaʻula) a me ka ʻono (salinity). Ua hōʻike ʻia kekahi mau haʻawina he pilina ma waena o ka ʻai nui ʻana i ka ʻiʻo i puhi ʻia a me ka piʻi nui ʻana o ka maʻi maʻi ʻaʻai a me ka rectal.
Eia nō naʻe, ʻaʻole i hōʻoia i kekahi mau noiʻi analytical ʻē aʻe i ka ulu ʻana o ka maʻi kanesa ma muli o ka nitrosamines. ʻO nā lula aupuni o ʻAmelika e koi aku i nā mea hana e hoʻohana i ka liʻiliʻi o nā nitrates a me nā nitrites e mālama ai i ka ʻiʻo a me ka hoʻohui ʻana i ka waikawa ascorbic, e hōʻemi ana i ka hoʻokumu ʻana o nā nitrosamines.
ʻO ka loaʻa ʻana o ka nui o nā nitrates i ka wai inu ma muli o ka nui o ka hoʻomoʻa ʻana o ka lepo a me ka hoʻohaumia ʻana o ka wai me nā feces holoholona hiki ke hana i nā hopena maikaʻi ʻole i ke koko. ʻO nā Nitrites, e launa pū me ka hemoglobin, hoʻololi iā ia i ke ʻano o ka methemoglobin, ʻaʻole hiki ke hoʻopili a lawe i ka oxygen. Ua hōʻike ʻia nā haʻawina ʻo nā keiki ma lalo o 6 mau makahiki ka mea maʻalahi loa i kēia mau loli i ka hemoglobin, hiki ke hoʻoulu i ka cyanosis o ka ʻili, ka luaʻi, a me nā mea make i ʻike ʻia. I ka poʻe mākua, e hui pū ʻia ka make ʻana o ka nitrate me ke poʻo, ka luhi, a me nā hōʻailona ʻē aʻe o ka hypoxia.
Hōʻike ʻo WHO, nā hui pili ʻEulopa a me ʻAmelika e hōʻike i ka ʻae ʻia o ka ʻai ʻana i kēlā me kēia lā o ka nitrates ma ke ʻano o 0-3.7 mg no ke kilo o ke kaumaha o ke kino i kēlā me kēia lā, e hōʻike kaʻawale ana i ka nui o kēia mau pūhui i ka wai - 10 mg / l no nitrates. a me 1 mg/l no nā nitrites. ʻO ka US Agency for Toxic Substances and Disease Registry, a me kahi ʻoihana Australia me nā mākaukau like, i kā lākou hōʻike e hōʻike ana i ka ʻike o ka nitrates (a hiki i 500 mg / kg) a me nā nitrites (a hiki i 200 mg / kg) i ʻae ʻia no kā lākou hoʻohana. i ka hana ʻana i nā huahana ʻiʻo a me nā sausages.
ʻO ke kauoha a ke Kuhina Ola i ka lā 13.05.2013 he papa inoa nui o nā mea kanu a me nā huaʻai me ka pae kiʻekiʻe i ʻae ʻia o nā nitrates, ʻo ka Laboratory Center o ka Sanitary and Epidemiological Service o Ukraine e haʻi ana i ka 5 mg e like me ka nui i ʻae ʻia o kēia mau pūhui no kēlā me kēia. kilokani o ke kaumaha kanaka i ka la.
Inā mākou e helu hou e like me nā waiwai i manaʻo ʻia o ka Ministry of Health, a laila no ke kanaka he 60 kg, palekana ke ʻai i ka 300 mg o nā nitrates i kēlā me kēia lā. ʻO kēia, no ka laʻana, 5 kg o ka watermelon, a i ʻole 10 kilograms o ka spinach, a i ʻole hoʻokahi a me ka hapa kilokani o ka ʻiʻo puhi a i ʻole nā sausages i hana ʻia a ulu ʻia e like me nā koi palekana o ka mokuʻāina.
I kēlā me kēia makahiki, koi ʻia ʻo Ukrainians e ʻai i nā melons a me nā melons me ka akahele ma muli o ke alo o nā nitrates. Hoʻomaopopo ka poʻe nūpepa a me ka poʻe loea i ka ʻai ʻana i nā mea kanu mua a hoʻoikaika i nā pae weliweli o ka nitrates i loko o ke kāpeti a me nā kukama. Ke ho'āʻo nei nā luna aupuni a me ka lehulehu e hoʻomalu i ka ʻike nitrate o nā huahana hua ma o lākou iho. Akā, ma nā ʻāina Komohana, i ka wā e kākau ai e pili ana i ka nitrates, hoʻoikaika lākou i ka nui o ka nui i ʻae ʻia no nā kānaka, ka hoʻāʻo ʻana i ka wai inu a me ka lepo ke kumu nui o ka nui o nā nitrates, a me ka hōʻole ʻana i ka ʻai ʻana i nā huahana ʻiʻo i loaʻa i nā nitrosamines pōʻino, me ka nānā ʻole i ka. nā hopena maikaʻi o ka nitrates ma ka ʻōnaehana cardiovascular.
