欧州域内排出量取引制度導入によって制度対象施設での環境マネジメントシステムや品質マネジメントシステム等の自主的なマネジメントシステム構築導入が推進された。あわせて、こうしたシステムのうち第三者認証制度を有するISO14001 やISO9001 の導入対象組織数も増加した。また、温室効果ガス量管理には適切なマネジメント体制が要求されており多くの手順類が必要となるが、こうした手順類の整備も取引制度導入後では徹底されてきたことがわかる。また、第三者認証制度を有するマネジメントシステムを有する組織においては、こうした手順類をシステムに組み込んで運営していることが今回の分析から判明した。以上より、制度導入によって自主的なマネジメントシステムの構築や、そのための手順整備が積極的にすすめられ、組織内体制強化が行われたことが判明した

Effect of Heating Temperature on Ammonia Emission in the Mainstream Aerosols from Heated Tobacco Products

Heated tobacco products are devices that deliver nicotine into the body via inhalation of the mainstream aerosols generated during direct and/or indirect heating of tobacco leaf material. Ammonia in aerosols potentially increases the alkalinity and, therefore, the proportion of free nicotine for easy absorption. Meanwhile, ammonia can be a cause of adverse health effects when involved in the aerosols. This study aimed to grasp the emission behaviour of ammonia in the mainstream aerosols generated from four kinds of devices that employ different heating temperatures from 40 to 350 °C. The aerosols were generated by a vaping machine following the CRM 81 puffing protocol. Ammonia in the forms of gas and particles was trapped in 5 mM oxalic acid and subsequently determined by ion chromatography. The results showed that the total emission amount of ammonia increased with an increase in the heating temperature regardless of the device used. The gas-particle distribution of ammonia also depended on the heating temperature; gaseous ammonia was only found in the device with 40 °C of the heating temperature. These results show that ammonia in the mainstream aerosols was emitted from a common thermal process, probably thermal extraction in water vapour from a tobacco leaf

Effectiveness of the Booster of SARS-CoV-2 Vaccine among Japanese Adolescents: A Cohort Study

Vaccination is effective in preventing COVID-19-related hospitalization among all age groups, but there is limited evidence on the effectiveness of the booster of the SARS-CoV-2 vaccine among adolescents. We analyzed the data on the status of SARS-CoV-2 infection and their vaccination profiles in adolescents aged 13–18 years in Soma city (Fukushima, Japan) (n = 1835) from 14 May to 15 June 2022. The crude incidence rate and 95% confidence interval were calculated with the negative-binomial regression model after classifying the immunization status. The crude effectiveness of a booster administration to prevent infections was estimated as 86.4% (95% confidence interval: 57.2–95.7) when compared with the primary vaccination alone. The results of this study support that the community-based mass vaccination campaign of a booster dose among adolescents has additional protection from COVID-19 during the period of the B.1.1.529 (omicron) variant wave
