yes but the larger particles are able to be expelled via sneezing coughing etc , they do not pass the genetic barriers like benzene rings etc
Epigenetic Influences and Disease
The external environment's effects upon genes can influence disease, and some of these effects can be inherited in humans. …
What Is Epigenetics? How Do Epigenetic Changes Affect Genes?
Epigenetics involves genetic control by factors other than an individual's DNA sequence. Epigenetic changes can switch genes on or off and determine which proteins are transcribed.
Epigenetics is involved in many normal cellular processes. Consider the fact that our cells all have the same DNA, but our bodies contain many different types of cells: neurons, liver cells, pancreatic cells, inflammatory cells, and others. How can this be? In short, cells, tissues, and organs differ because they have certain sets of genes that are "turned on" or expressed, as well as other sets that are "turned off" or inhibited. Epigenetic silencing is one way to turn genes off, and it can contribute to differential expression. Silencing might also explain, in part, why genetic twins are not phenotypically identical. In addition, epigenetics is important for X-chromosome inactivation in female mammals, which is necessary so that females do not have twice the number of X-chromosome gene products as males (Egger et al., 2004). Thus, the significance of turning genes off via epigenetic changes is readily apparent.
Within cells, there are three systems that can interact with each other to silence genes: DNA methylation, histone modifications, and RNA-associated silencing…

I spend a lot of time in an island area where one man ran the fuel delivery boat for years
gas to a few stops, but primarily home fuel and diesel
he use to stand by the nozzle
at about age fifty he came down with several different cancers and various other medical conditions and croaked.
he was a nice man (RIP)
Not an unusual story. Unfortunately.
As I said earlier, I know diesel is bad bad bad because I get really sick really fast when I breathe the exhaust. ...Do my best to avoid traffic areas.
