Ke alakaʻi nei ʻo COVID-19 Lockdown i ka hōʻemi ʻana i ka PM2.5 ma 11 o 12 o nā kūlanakauhale nui o Kina.
ʻO ka laka i hana ʻia e ka maʻi maʻi COVID-19 i ʻike i kae emi ana ka nui o na kaa a me na kaa kaa ma ke alanuie 77% a me 36%, pakahi.Ua pani pū ʻia nā haneli o nā hale hana no kahi manawa lōʻihi.
ʻOiai ke hōʻike ʻana o ka loiloi i ka piʻi ʻana oNā pae PM2.5 i ka wā o Pepeluali, ma laila he mau lonoi ka manawa mai Ianuali a ʻApelila, ua hoʻemi ʻia nā pae PM2.5 e 18%.
He kūpono ke emi ʻana o PM 2.5 ma Kina i Malaki, akā ʻo ia ka hihia?
Ua nānā ʻo ia i ʻumikūmālua o nā kūlanakauhale nui o Kina e ʻike i ke ʻano o kā lākou PM2.5 pae i ka wā o ka laka.
Mai loko mai o nā kūlanakauhale 12 i kālailai ʻia, ua ʻike lākou a pau i ka emi ʻana o nā pae PM2.5 no Malaki a me ʻApelila, i hoʻohālikelike ʻia i hoʻokahi makahiki ma mua, koe wale nō ʻo Shenzhen.
Ua ʻike ʻo Shenzhen i kahi piʻi haʻahaʻa o nā pae PM2.5 mai hoʻokahi makahiki ma mua o 3%.
ʻO nā kūlanakauhale i ʻike i nā hōʻemi nui loa ma nā pae PM2.5 ʻo Beijing, Shanghai, Tianjin, a me Wuhan, me nā pae PM2.5 e hāʻule ana i 34% no Beijing a me Shanghai.
ʻIke ʻia o kēlā me kēia mahina
No ka loaʻa ʻana o kahi manaʻo maʻalahi o ka loli ʻana o nā pae PM2.5 o Kina i ka wā o ka laka coronavirus, hiki iā mākou ke hoʻokaʻawale i ka ʻikepili i ka mahina.
Malaki 2019 vs. Malaki 2020
I Malaki, ua paʻa loa ʻo Kina ma lalo o ka laka, me nā kūlanakauhale he nui i pani ʻia a kaupalena ʻia ka halihali.Ua ʻike nā kūlanakauhale 11 i ka emi ʻana o ka PM2.5 i Malaki.
ʻO ke kūlanakauhale wale nō i ʻike i ka piʻi ʻana o nā pae PM2.5 i kēia manawa ʻo Xiʻan, me ka piʻi ʻana o nā pae PM2.5 he 4%.
Ma ka awelika, ua emi ka pae PM2.5 o nā kūlanakauhale he 12 i ka 22%, a waiho ʻia ʻo Xiʻan ma ke ʻano he outlier nui.
ʻApelila 2020 vs. ʻApelila 2019
Ua ʻike ʻo ʻApelila i ka maʻalahi o nā hana paʻa ma kahi o nā kūlanakauhale he nui o Kina, ua pili kēia me kahihoʻonui i ka hoʻohana uila no ʻApelila.Hoʻopili ka ʻikepili PM2.5 o ʻApelila me ka hoʻohana ʻana i ka uila, e hōʻike ana i nā pae kiʻekiʻe PM2.5 a pena i ke kiʻi ʻokoʻa loa iā Malaki.
Ua ʻike ʻia ka piʻi ʻana o nā pae PM2.5 ma 6 o nā kūlanakauhale he 12.Ke hoʻohālikelike ʻia me ka hoʻohaʻahaʻa awelika o nā pae PM2.5 (makahiki ma ka makahiki) o 22% i Malaki, ua ʻike ʻo ʻApelila i ka piʻi awelika o nā pae PM2.5 o 2%.
I ʻApelila, piʻi nui nā pae PM2.5 o Shenyang mai 49 micrograms i Malaki 2019 a i 58 micrograms i ʻApelila 2020.
ʻO ka ʻoiaʻiʻo, ʻo ʻApelila 2020 ka pōʻino loa o ʻApelila mai ʻApelila 2015 no Shenyang.
ʻO nā kumu paha no ka piʻi nui ʻana o Shenyang i nā pae PM2.5 ma muli o kahika piʻi ʻana o nā kaʻa, nā au anu a me ka hoʻomaka hou ʻana o nā hale hana.
Nā hopena o ka Coronavirus Lockdown ma PM2.5
Ua maopopo ʻo Malaki - i ka wā i hoʻopaʻa ʻia ai ka neʻe ʻana a me ka hana ma Kina - ua hāʻule nā pae pollution i hoʻohālikelike ʻia me ka makahiki i hala.
Ma ka ʻaoʻao ʻaoʻao o nā pae PM2.5 o Kina no ka lā ma ka hopena o Malaki e hoʻi i ka home i kēia wahi (ʻoi aku ka nui o nā kiko ʻōmaʻomaʻo ʻoi aku ka maikaʻi o ka ea).
He Ala lōʻihi naʻe e hui aiʻO ka pahuhopu o ka maikaʻi o ka ea WHO
Ua hāʻule ka awelika PM2.5 ma nā kūlanakauhale he 12 mai 42μg/m3 a i 36μg/m3 i ka hoʻohālikelike ʻana i ka makahiki 2019 a hiki i 2020. He hana kupanaha kēlā.
Eia naʻe, ʻoiai ʻo ka laka,He 3.6 mau manawa kiʻekiʻe ke kiʻekiʻe o ka pollution o Kina ma mua o ka palena makahiki o ka World Health Organization o 10μg/m3..
ʻAʻole hoʻokahi o nā kūlanakauhale 12 i nānā ʻia ma lalo o ka palena makahiki o WHO.
Ke laina lalo: Nā pae PM2.5 o Kina i ka wā o ka laka COVID-19
ʻO ka awelika PM2.5 pae no 12 o nā kūlanakauhale nui o Kina i hoʻemi ʻia e 12%, i Malaki-ʻApelila, hoʻohālikelike ʻia me ka makahiki i hala.
Eia naʻe, ʻoi aku ka nui o ka PM2.5 ma ka awelika he 3.6 mau manawa i ka palena makahiki o WHO.
He aha hou aʻe, e hōʻike ana ka hōʻike ʻana i kēlā me kēia mahina i ka rebound i nā pae PM2.5 no ʻApelila 2020.
