He aha te mea MAC? kukū whakaaetia mōrahi o matū kino i roto i te rangi

MPC pollutants - he uara whakaaetia nga pūhui matū poke i roto i roto i te oneone, te wai rangi ranei e kore e pā - kino take epā - i runga i kaiao ora. Ko te uara i roto i te waeine e tika ana kua oti te whakarite e te akoranga toxicological.

Āhuatanga o MPC rite te mita

He aha te mea te MAC i ture kaiao? Ko te tohu matua o tenei taupuhi kaiao ahumahi, i arahina hinonga ahumahi katoa. MAC uara o matū i takea ka tohaina e te momo o te hanganga matū me ngā pānga toxicological i runga i kaiao ora. paerewa kāwanatanga whakapumautia, tautukunga ki nei he whakahauanga.

Tei runga i te taiao, i kei matū kino, whanganga i MPC:

• mg / DM ³ - ine i roto i te wai ōnuku;
• mg / m ³ - te inenga i roto i te huru, me te rangi o te wāhi mahi;
• mg / kg - ki te whakatau i te taupū roto i te whenua.

A, no te tango memenge uara rohe ki pūkete te pānga te waipiro e kore anake i runga i te tangata, engari ano hoki mo nga kaiao ora katoa i roto i te whānui. Ka taea e hāngai ki ngā ture te whakaora i te rauwiringa kaiao katoa, e kore e takitahi momo o te wao nui a.

whakarōpū

MPC o matū kino, i runga i te tohu o te pānga i runga i kaiao ora kei e wehea ki te 4 ngā wāhanga mōrearea:

1. Ahau piha - he tino mōrearea.
2. Class II - tino kino.
3. piha III - mōrearea.
4. piha IV - tika kino.

Tei runga i te rōpū mōrearea oko parakino, taui tona wa MAC me te noho i roto i te taiao o kaiao ora i roto i te aroaro o pūhui matū.

momo o MPC

Tei runga i te paearu mō mawehe atu aromatawai taiao e rave rahi uara MPC.

Ki te tohatoha i te rohe ahumahi:

• MPCwa - Kei te whakamahia ki te aromatawai i te huru hauora o te huru o te mahi rohe. Ko te rohe te mahi - he wāhi i roto i nei ko te kaimahi i roto i te mahi, ngā 2 mita i runga ake i te tūāpapa. whakapuaki te tau whakarea i te nui o pollutants i te rangi, e kore e meinga tetahi abnormalities i roto i te hauora o te tangata mō te maha o ngā tekau tau.
• PDKp.p. - tu atu i roto i ngā tipu ahumahi ranei i runga i te pae motuhake. Tikanga, ka rite ki te uara tango te uara 0.3 MPCwa

Hoki ngā wāhi tāone, i reira e te tahi atu paerewa mō ngā āhuatanga kōhauhau taiao, whakaritea nei e te āhuatanga e whai ake nei:

• PDKn.p. - te katoa uara o te paranga tīkina i te huru o te kainga. Motuhaketia, te toharite auau tuku ia me te parahanga kotahi mōrahi.
• PDKm.r. - te maha o paranga i te huru i roto i ngā wāhi tāone, faaiteraa mōrahi e te mea tika hoki te inhalation kotahi. tātai tau whakarea e na e kore e meinga te taonga he tauhohenga ki akiaki matū i te rongo poto (āhua 20 meneti).
• PDKs.s. - Whakarite te nui o matū kino i roto i te kukū e kua kore mana kino i runga i te hauora tangata, ngā te inhalation karaka.

kia mohio ki te reira e taua tāone, me te MPC wāhi mahi. MPCwa tātai i te raraunga tuatahi e whai ake nei:

• i roto i te taiao poke he pakeke ki te hauora pai;
• noho iti ki te whakaahuatanga mahi, a te nuinga o kaua e nui ake te 8 haora.

matū kino i roto i te huru o te kainga i te pānga i runga i ia te wahine e noho: pakeke tamaiti ranei, e mate ana hauora ranei, i te mea e huri noa i te karaka, me te tonu puta noa i te ora. Nō reira, hoki te taua pollutants taea te whakaritea tino rerekē i ia atu uara o ngä nohanga whakaaetia mōrahi. tau whakarea Tikanga MPC i roto i te rohe mahi ko PDKn.p. nui teitei

Whakatau uara rohe i roto i te wai, me te oneone

He aha te mea te kukū whakaaetia mōrahi o Faarii? Ko te kukū paerewa whakapumautia o te parakino ia 1 rita o te wai. kua oti te whakarite motuhake uara tau whakarea mō ia momo o te awa. Wehewehe te wai ika-ōhanga, inu me te mau opuaraa kāinga.

Whakatau i o MPC o pollutants i roto i te oneone - te mahi uaua tino. Tatau i runga i nga āhuatanga oneone me te āhua matū o matū kino. Tohu e rerekē tonu, a kahore e tangohia i roto i ngā uara tepu mo ia pūhui parakino.

Tohatoha o mōrahi ngä nohanga whakaaetia o te rongo ki te natura

He aha te mea te kukū whakaaetia mōrahi o pūhui matū, ki te taea ia kaihoko mahi rerekē?

Hoki te whakarōpū pūnahanaha o ngā matū kino emit rave rahi rōpū o pānga ngā āhuatanga āhuatanga i runga i te rauropi ora, ngā te tangata:

• whānui paitini;
• hōhā;
• sensitizers;
• carcinogens;
• mutagens;
• e pa ana te hauora uri.

Kei ia rōpū āhuatanga e tohu motuhake o paihana, te wā o ngā mahi, me te ahu MPCs.

Täoke ki te pānga paitini whānui

meinga tāoke Common poisoning nui o te rauropi katoa. Ko te maumaui tino kitea kitea e te pūnaha io tangata: i reira he haehae, disorders mahara, pāpāngia. Ko te rōpū o ngā matū o tāoke whānui ngā waiwaro kakara , me ratou nitro me amido pärönaki, pūhui ūkuikui organic, māota, me te tahi mau pūhui pararopi.

Ko te noa tino o ratou:

• Te ateneke me ona pūhui;
• benzene, toluene, aniline, xylene;
• dichloroethane;
• HG;
• Pb;
• waro waikura (IV).

Belgium o tokomaha o nga matū puta kore anake i roto i te whakangao engari ano i roto i te ora ia rā.

MPC i roto i te matū paitini rangi whānui

A feruri i te mahi o ia rā toharite me te kotahi MAC i roto i te rangi, me te wāhi mahi tāone. Hoki te haratau me te mārama, te aroaro mōhiohio i roto i te hanga ripa.

Ko te kukū toharite o matū kino tā taunekeneke ki te tinana tangata mo te maha o nga tau, kahore te whanaketanga o tetahi tupu.

Mahi irritating matū

pā pūhui matū te kiri, kiriuhi mucous me te wahi romahā. I roto i te nuinga o te wā, te wāhi o irritating matū ngāue kōnakonako me waikura o te hauota , me te whanariki.

inhalation roa o kohu hua kino i roto i nui matehā disorders, haurangi, me te mate.

Sensitizers me huru MPC

Matū sensitizing pānga meinga he urupare kë i roto i te tangata. Na roto i te pūhui noa o tenei rōpū ngā aldehydes me hexachloran.

Sensitizers tukua ki te huru i roto i ngingiha me ngā mahi ahumahi. tukua te nui iti o te formaldehyde te me te kāinga: kua kitea taua mea i roto i maha whare me ngā rauemi mutunga, taonga.

Carcinogens me mutagens

Ko te rōpū tino mōrearea o paranga matū, e whakaawe i runga i te tinana tangata mo te wa roa hoohonutanga. Carcinogens a Mutagens - matū puai ki te wā moe roa o te mahi. Na roto i te carcinogens ngā papa kiripaka, teriuma, benzpyrene, amines kakara. whakapataritari ratou te hanganga o ngā pukupuku mārere.

Mutagens whakapataritari huringa i roto i te tohuira tangata, e kua tuku ki uri. Ēnei ngā matū iratuki, konupora, mata, peroxides organic me te formaldehyde.

He maha matū mutagenic ato'a pā te hauora whakaputa uri, a ka whakauru benzene me tetahi pärönaki ona, mata, te kakano, konupora, patukīrea, chloroprene me etahi atu.
