The lower limits of retention for both benzene and toluene are unexpectedly low compared to the retention of bi-and tricyclic aromatic hydrocarbons, which have retentions from cigarette smoke above 95%. This is probably caused by the fact that monocyclic aromatic hydrocarbons are present practically ...
When compared to the transcriptome changes that occurred in the female and male placentas, most of the top DEGs in the male placenta were downregulated after maternal benzene exposure (Figures 4C and 4D). Moreover, the top 5 biological processes affected in female and male placentas are very ...
aBelow is a list of chemicals that may or may not be found in cigarette smoke. To the best of your knowledge, indicate which chemicals, if any, are in cigarette smoke. If you do not know, use the response "Don't know".Select one in each row Yes No Don't know 下面是在香烟%[tra...
Benzene is an acute as well as a chronictoxicant. The acute toxic effects from inhalation,ingestion, and skin contact are low tomoderate. The symptoms in humans are hallucination,distorted perception, euphoria, somnolence,nausea, vomiting, and headache. Thenarcotic effects in humans may occur from...
There are a number of sources of benzene exposure, includingproductssuch as solvents, detergents, plastics, synthetic fibers, dyes, rubber, resins, paint, and many other items. Benzene is also found in cigarette smoke and within the petroleum industry. Those at highest risk of prolonged or high...

However, in simple terms, there are some well-defined key events that seem to be prerequisites for this chemical to become toxic. These key events are cited in the description of the mode of action of benzene, namely: (1) the metabolization of benzene to benzene oxide; (2) the ...
1,2,4-Trimethylbenzene (mesitylene) is an aromatic hydrocarbon compound commonly present in commercial solvents encompassing their boiling range. Mesitylene are the most common isomer used in commercial applications. Aromatic hydrocarbons in hydrocarbon solvents are predominantly alkylated one ring structures...
Both benzene and HQ are also found in cigarette smoke and HQ is the most abundant pro-oxidant compound in cigarette smoke tar [2], though HQ is also found in the plasma of nonsmoker individuals living a Western lifestyle [3]. In addition to industrial exposure, there is significant ...
chromosome 6p25; its gene product uses dihydronicotinamide riboside (NRH) instead of NAD(P)H as its electron donor.8 Both NQO1 and NQO2 are induced by oxidative stress, dioxin, and polycyclic aromatic hydrocarbons such as those found in combustion processes (e.g., cigarette smoke, urban smog...
