Toxic chemical residues of tobacco smoke on dust tosses challenges on cleaning household surfaces and can build up over a long time creating reservoirs of third-hand toxic smoke.
COVID-19 pandemic has created a number of challenges, including that many are spending more time at home than ever before. This is a significant problem for those with neighbors who smoke. Smoking continues to be a problem in //multi-unit housing, and while stay-at-home orders have helped to reduce transmission of COVID-19, they have also increased exposure to secondhand smoke from neighbors.
‘Tobacco smoking residues on dust and household surfaces can be difficult and expensive to completely remove.’
After the second-hand smoke, the toxic residues of tobacco smoke and e-cigarette vapors remain as third-hand smoke. These chemicals stick to dust and other household surfaces and can build up over a long time and create reservoirs of third-hand toxic smoke.Third-hand smoke can be hazardous to children and adults with weak immune systems. Also, removal of third-hand smoke is difficult and expensive.
Potential third-hand smoke cleaning methods were examined by a group of researchers led by Georg Matt of San Diego State University. The study, "Remediating Third-hand Smoke Pollution in Multiunit Housing: Temporary Reductions and the Challenges of Persistent Reservoirs," will be published Sept. 15 in the journal Nicotine and Tobacco Research.
The researchers looked for nicotine on dusts and house hold surfaces. They checked the homes of strict non-smokers to confirm that it was not caused by the residents or guests but the neighbors or previous residents who smoked.
"We wanted to see if there were any solutions available for people who live in homes that are polluted with third-hand smoke. We explored three options for cleaning, and tested apartments for nicotine contamination before, after, and three months after each cleaning", says Matt.

"We would like to be able to tell residents that there is a simple way to remove this contamination permanently, but that is not what we found. What we can say, as a result of this study, is that there are two important steps you can take to reduce third-hand smoke contamination and make your home safer.", Matt continued.
