BTEX Maruziyet Verilerinin Sektörel Açıdan İncelenmesi

open access: yesAfet ve Risk Dergisi, 2022
Benzen, toluen, etil benzen ve ksilen (BTEX) havadaki önemli toksik uçucu organik bileşiklerdendir. Kapalı çalışma ortamında boyalar, çözücüler, yapıştırıcılar ve temizlik maddeleri gibi çeşitli emisyon kaynaklarına sahiptirler. Ortama salındıklarında hızlı bir şeklide havaya karışırlar ve vücuda solunum yoluyla kolayca girebilirler.
