Qhov tseem ceeb ntawm kev xeem ntawv pov thawj German PAHs yog dab tsi?

Qhov tseem ceeb ntawm kev xeem ntawv pov thawj German PAHs yog dab tsi?

1. Qhov ntau thiab tsawg ntawm kev kuaj pom PAHs - cov khoom siv xws li cov khoom siv hluav taws xob thiab cov motors:

1) Cov khoom siv roj hmab

2) Cov khoom yas

3) Cov yas tsheb

4) Cov khoom siv roj hmab - cov ntaub ntawv ntim khoom noj

5) Cov Khoom Ua Si

6) Cov ntaub ntawv thawv, thiab lwm yam

7) Lwm cov ntaub ntawv, thiab lwm yam.

2. Kev Taw Qhia Txog PAHs

Polycyclic aromatic hydrocarbons yog PAHs, uas yog lus Askiv luv ntawm polycyclic aromatic

hydrocarbons. Polycyclic aromatic hydrocarbons (PAHs) yog cov tshuaj carcinogen heev. Lub teb chaws Yelemees muaj

tau tshaj tawm cov cai tias polycyclic aromatic hydrocarbons (PAHs) yog cov tshuaj carcinogens heev. Hluav taws xob

cov cuab yeej muag hauv lub teb chaws Yelemees yuav tsum tau kuaj xyuas kom tsis muaj PAHs ntau dhau ua ntej lawv tuaj yeem muag hauv khw.

qhov siab tshaj plaws uas tso cai rau tag nrho cov PAHs yog 10mg / kg.

3. Tam sim no, 16 hom PAHs uas feem ntau pom muaj xws li 16 hom tshuaj zoo sib xws:

1) Naphthalene

2) Acenaphtylene acenaphthene

3) Acenaphtene

4) Fluorene

5) Phenanthrene

6) Anthracene

7) Fluoranthene

8) Pyrene

9) Benzo(a)anthracene

10) Chrysene

11) Benzo(b)fluoranthene

12) Benzo(k)fluoranthene

13) Benzo(a)pyrene

14) Indeno(1,2,3-cd)pyrene

15) Dibenzo(a,h)anthracene

16) Benzo(g,hi)perylene

Peb muab cov khoom siv roj hmab uas dhau qhov kev xeem PAHs.
