{"doi":"10.20517/jeea.2023.28","title":"Cotton pillow samplers for assessment of thirdhand smoke in homes of smokers and nonsmokers with children","abstract":"Secondhand smoke (SHS) exposure is a major source of illnesses in children and leaves a persistent and toxic residue indoors called thirdhand smoke (THS) that deposits on surfaces, is absorbed into materials, collects in house dust, and is re-emitted into the air. THS, like SHS, has been shown to contain multiple toxic chemicals including carcinogenic tobacco-specific nitrosamines (TSNAs). Children are highly susceptible to tobacco smoke pollutants, and simple methods for assessing children's SHS and THS exposure are needed. Therefore, we evaluated the performance of a cotton pillow used as a passive sampler in homes of children with caregivers who smoke tobacco, with and without home smoking bans, as well as nonsmokers. We deployed a commercially available organic cotton travel pillow, which was left in the home for a median 9.1 days. Pillow component nicotine levels were significantly higher in homes of smokers without a ban as compared to smokers and nonsmokers who had a ban (e.g., median pillowcase nicotine 337.7 ng/g per day vs. 72.5 ng/g per day and 0.1 ng/g per day, respectively) and differences were similar to those for air nicotine. Pillowcase TSNAs were detected mainly in the homes of smokers without a smoking ban. Pillow component (pillowcase, fabric, and filling) nicotine levels were highly correlated with air nicotine levels (rho=0.76-0.88, all p<0.001). Nicotine in the pillow components was also highly correlated with urinary cotinine in the children (rho=0.65 to 0.81, all p<0.001) and other measures of tobacco smoke exposure. Pillow performance as a sampler is promising, given the ease and simplicity of sample deployment.","journal":"Journal of Environmental Exposure Assessment","year":2023,"id":387033,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9586,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":356987,"name":"Nicolás López-Gálvez","orcid":"0000-0001-8385-1334","position":1,"is_corresponding":false},{"id":356990,"name":"Georg E.
