Third-hand tobacco smoke is a real threat to public health, the study suggests. Third-hand smoke is residual pollution from cigarette smoking that adheres to other surfaces in places and walls where smoke has previously been produced. A new study suggests that this third-hand smoke can travel through humans in large quantities to indoor and non-smoking environments.
Published in the journal Science Advances, the findings suggest that even if someone is in a room where no one has smoked, the person may be exposed to many dangerous chemical compounds that make cigarette smoke, depending on who else entered the room or saw her first.
Third-party smoke is produced by direct contamination of surfaces (eg, Smokers’ bodies and clothing, interior goods and surfaces, and construction materials) with hazardous organic compounds from tobacco combustion, but does not include primary particles in the air. They are.
In real-world situations, we see concentrated emissions of dangerous gases from groups of people who were previously exposed to tobacco smoke, when they enter a non-smoking space with strict regulations against indoor smoking Do, the lead author of the study, Dr. Drew Gentner said.
Researcher at the Department of Chemical and Environmental Engineering at Yale University and the Max Planck Institute for Chemistry. People are suitable carriers of third-party smoke pollutants in other settings. Therefore, the idea that a person is protected from the possible health effects of cigarette smoke, since they are not directly exposed to secondhand smoke.
In the study, Drs. Gentner and his colleagues brought highly sensitive analytical equipment to the cinema to track thousands of compounds present as gases or particles over the course of a week. A wide range of volatile organic compounds found in tobacco smoke increased dramatically when audiences came to watch movies.
These increases were modest for G-rated movies, while audiences for R-rated movies, in which filmmakers were more likely to smoke or be exposed to smoking, consistently released large amounts of these compounds in theaters. The relative proportions of these excreted compounds confirmed that they came from slightly aged cigarette smoke.
Study first author Roger Shue, a PhD, said: “Despite the rules, people who smoke, near entrances and near air, are still producing dangerous chemicals from cigarette smoke indoors ” Student in the Department of Chemical and Environmental Engineering at Yale University.
The amount of these dangerous and reactive gases was not trivial. Gas emissions were equivalent to exposure to 1–10 secondhand smoke cigarettes over a period of one hour. These air emissions and concentrations increased with the arrival of the audience and decreased with time, but not entirely, even when the spectators left.
In many cases, moviegoers left a continuous contamination while following the next few days to the cinema without it. The reason for this is that the chemicals do not remain completely in the air, but are also advertised on various surfaces and furniture, such as this with third-party smoke pollution in places where smoke has been produced.
Scientists also found prominence of nitrogen-containing compounds from cigarettes, which may have migrated from people to other interior surfaces. In particular, we saw that nicotine was the most prominent compound in history, co-author Jenna Ditto, Ph.D. Student in the Department of Chemical and Environmental Engineering at Yale University.
A new concern for families of smokers: ‘Third smoke’. Michael Miller, 44, smokes more to save his sons and daughter from the fumes of their Marlborough Ultra Lights. He takes it out. After his 7 o’clock coffee, he leaves his home in Cincinnati to smoke his first cigarette of the day.
Then, as a branch manager for a road safety construction company, he smokes dozens more on a sidewalk. Tobacco never appears when Miller is training on a baseball or soccer field, or when he is in the car with his children. But when he’s alone on the road, he sometimes knocks on the windows and turns on.
I know [cigarettes] are bad, said Miller. I know I need to quit my job. The new findings highlight the scientific community’s efforts to identify the potential risks of another by-product of cigarettes, which may last Miller’s precautions and affect his children: “Third Smoke.”
A recent study in the Tobacco Control magazine found high levels of nicotine in the hands of children smokers, concerns about smoke number three, a name given to nicotine and chemical residues in cigarettes, and left behind cigarette smoke that can adhere to skin, hair, clothing, rugs, and walls. This thin film can be lifted to the touch or released into the air when disturbed.
The researchers examined 25 children with respiratory problems in an emergency room associated with exposure to secondhand smoke. They found that the average level of nicotine in children’s hands was three times higher than the level of nicotine found in the hands of smokers in adults who smoked. He stated that nicotine on the skin of non-smokers is a good indicator to measure exposure to third-party smoke.
The researchers wrote: Because nicotine is tobacco-specific, its presence in children’s hands can serve as a substitute for tobacco smoke contamination in its immediate surroundings. They also found that all but one of the children had detectable levels in cotinine saliva, a biomarker for nicotine exposure. All of the children in the study had parents who smoked but did not smoke.
High nicotine readings on children’s hands, combined with the “light smoking” habits of most of their parents, author E. Led by Melinda Mahabi-Gittens indicated that these toxins may come from a source other than direct use of cigarettes. Let’s smoke
Apparently they are getting it from somewhere, and maybe it could be this third smoke connection, said Mahabi-Gittens. Children are at a higher risk of developing health complications from smoking third than adults. According to a 2004 study written by psychology professor George Matt at San Diego State University, babies can stay indoors longer and be surrounded by contaminated objects such as rugs and blankets.
A baby’s tendency to put its hand in its mouth increases the child’s chances of ingesting toxic waste. We Researchers at the Centers for Disease Control and Prevention estimate that since 1964 at least 2.5 million nonsmokers have died of diseases associated with exposure to cigarette smoke.
Third-hand smoke can linger in one area long after a cigarette or cigar is inhaled, up to five years, Matt said.
“Tobacco smoke doesn’t go up in the air and it goes away and goes away,” said Matt. “It is an illusion”. The negative health consequences of secondhand smoke are well established.
We Researchers at the Centers for Disease Control and Prevention estimate that since 1964 at least 2.5 million nonsmokers have died from diseases associated with exposure to cigarette smoke. By contrast, research on third-century smoke had gained popularity a decade earlier, but according to many studies, mixing toxins can negatively affect health.
An animal model simulating homes contaminated with third-hand smoke found that the chemicals damaged the lungs, lungs, and healing abilities of the mice. A separate 2010 study found that third-party smoke mixed with nitrous acid, a gas that sometimes escapes from a leaking gas stove, can form cancer-causing chemicals.
These toxins have also been shown to damage human DNA. Anwar Mujib, Program Officer for the Tobacco-Related Disease Research Program, said: “For everyone, I think the evidence we are collecting is basically about high levels of risk for young children and children and possibly mothers. He points out.”
Unfortunately, removing the third smoke from a child’s environment is not an easy task. The variety of compounds that make up cigarette waste react differently to cleaning products, Matt said, making it difficult to purify a stain of contaminants.
Governments and agencies across the country have attempted to curb the risk of exposure to smoke by enforcing the tobacco ban. Forty states and the District of Columbia have enacted local smoke-free legislation, according to the Americans, a group that advocates for neon rights.
While most of these laws are intended to address secondhand smoke exposure, an unintended benefit of the ordinances is the reduction of third-hand smoke, said Stanton Glantz, professor of medicine and director of the Center for Research and Education for Tobacco Control from the University of California-San Francisco.
Reynolds American Inc., the second-largest tobacco company in the United States, declined to comment on the study. The United States’ leading cigarette maker, the Altria Group, did not respond to requests for comment.
Mujib said more work needs to be done to better understand the risks of third-party smoke.
The researchers still don’t know the extent of the risk that causes harm. He added that other potential pollutants in the environment should also be identified to “adequately characterize the third smoke hazard.”
Miller suspects the number three smoke threat to his family, but is determined to quit on his 45th birthday in July of this year. With the help of medicine, he hopes to break the habit of reminding his children to try to kill him. I think I have a lot worse on my hands than any tar,”he said.
