Benzen. Dokumentacja proponowanych dopuszczalnych wielkości narażenia zawodowego

Abstract: Benzen jest bezbarwną lub lekko żółtą cieczą o charakterystycznym zapachu. Naturalnymi źródłami benzenu są gazy emitowane z wulkanów i pożarów lasów oraz produkty ropopochodne. Benzen stosuje się przede wszystkim jako rozpuszczalnik oraz materiał wyjściowy w syntezie wielu chemikaliów. W Polsce w 2020 r. 28 osób pracowało w narażeniu na benzen o stężeniach powyżej obowiązującej wartości NDS. Benzen działa narkotycznie w warunkach zatrucia ostrego. Ciekły działa drażniąco. Po narażeniu przewlekłym u ludzi obser… Show more

“…Technical purity HCH is a mixture of several isomers, formerly used as an insecticide in the United States, currently not produced in the US [ 24 ]. HCH is moderately acutely toxic, and LD50 values for various animal species range from about 60 to over 3700 mg/kg body weight, from 900 to >8000 mg/kg body weight (dermal exposure), and 690 mg/m 3 (inhalation) [ 25 ].…”

“…Single isomers are carcinogenic. Struciński [ 25 ] suspects that the α-isomer is the isomer with the highest carcinogenic activity. HCH isomers have an affinity for adipose tissue; they are relatively quickly metabolized and excreted from the body compared to other chloro-organic compounds.…”
