Analysis of the results Informative articles Bibliography Analyse which sections the newspaper article contains. 25 Some scientific research has a social impact. Imagine that you are responsible for childhood and youth matters in your town hall. Write a letter to various organisations (sports, leisure, neighbourhood, etc.) with five recommendations to avoid the problem of “third-hand smoke”. Use the content of this article and what you have learnt about gases to justify your recommendations. For example, how can tobacco smoke from adults reach children? Researchers find traces of tobacco on the hands of most children, including the children of non-smoking parents A study has detected nicotine in 97 % of over 500 children who were tested . […] Their habit of touching things and then touching their mouths makes them vulnerable to third-hand smoke. This is the chemical residue of tobacco smoke that remains in dust and on surfaces after someone smokes or vapes. Researchers at San Diego State University [USA] took samples from the hands of children of 11 years old and younger to measure the levels of nicotine on them. The results show that more than 97 % of the 504 children had nicotine on their hands. More surprisingly, more than 95 % of the children in non-smoking households also had this residue on them. More awareness The leader of the data collection is Melinda Mahabee-Gittens, a paediatric emergency physician and clinical researcher at Cincinnati Children's Hospital Medical Center. She says that "one result of this research should be to include third-hand smoke as part of the education programmes aimed at making parents quit smoking". The most disadvantaged families are at the most risk "Children from disadvantaged families and the children of Black parents suf fer the most from this involuntar y exposure."
