The geopolitical conflict between Russia and Ukraine has disrupted Europe's natural gas supplies, driving up gas prices and leading to a shift towards biomass for residential heating during colder months. This study assessed the consequent air quality and toxicological impacts in Milan, Italy, focusing on fine particulate matter (PM, d < 2.5 μm) emissions.

We collected six sets of PM samples in five urban location sites around the world over long time periods varying from weeks to months, intentionally selected for their PM to be dominated by unique emission sources: (1) PM produced mainly by traffic emissions in central Los Angeles, United States (US); (2) PM dominated by biomass burning in Milan, Italy; (3) PM formed by secondary photochemical reactions thus dominated by secondary aerosols in Athens, Greece; (4) PM emitted by refinery and dust resuspension in Riyadh, Saudi Arabia (SA); (5) PM generated by dust storms in Riyadh, SA, and (6) PM produced mainly by industrial and traffic emissions in Beirut, Lebanon. The PM samples were chemically analyzed and their oxidative potential were quantified by employing the dithiothreitol (DTT) assay.

The goal of this study was to characterize changes in components and toxicological properties of PM during the nationwide 2019-Coronavirus (COVID-19) lockdown restrictions in Milan, Italy. Time-integrated PM filters were collected at a residential site in Milan metropolitan area from April 11th to June 3rd at 2020, encompassing full-lockdown (FL), the followed partial-lockdown (PL2), and full-relaxation (FR) periods of COVID-19 restrictions. The collected filters were analyzed for elemental and organic carbon (EC/OC), water-soluble organic carbon (WSOC), individual organic species (e.

Atmospheric particulate matter (PM) has multiple adverse effects on human health, high temperatures are also associated with adverse health outcomes, and the frequency of cardiovascular events (CVEs) varies with season. We investigated a hypothesized increase in PM-related accident and emergency (A&E) presentations for CVE with high temperature, warm season, days of high influenza incidence, and in people with a cancer diagnosis, using a time-stratified case-crossover study design. Outcomes were associations of A&E presentation for CVE with atmospheric PM ≤ 10 μm (PM), season, and air temperature.

There are numerous harmful substances produced by these devices, such as metals, organic compounds, and aldehydes. The presence of formaldehyde is particularly worrying: its indoor concentration is 2.

The study has the objective to contribute to the existing literature on the health risks associated with fine particle pollution (PM2.5) due to steel production with data from Brazil.

One of the biggest Italian Steel Manufacturer, with several factories in Italy and abroad, the Marcegaglia Group, recently introduced the outdoor smoking ban within the perimeter of all their factories. In order to encourage their smoker employees to quit, the Marcegaglia management decided to set up an educational framework by measuring the PM1, PM2.

The aim of the present study was to investigate the emission of PM generated by e-cigarettes and normal cigarettes under real-life conditions.
Methods: Real-time measurement and comparison of PM and ultrafine particles (UFP) generated by electronic cigarettes with and without nicotine and by normal cigarettes in a 50 m3 office of an Italian comprehensive cancer center was performed.
Electronic cigarettes (e-cigarettes) have attracted considerable attention as a possible alternative to tobacco cigarettes, but uncertainties about their impact on health and indoor air quality as well as their commercial success without a clear regulatory framework are arousing concern. We have therefore tried to summarize the health-related implications of the use of e-cigarettes in order to help physicians and health professionals provide accurate information on this device. Given the lack of unequivocal scientific data on their toxicity and safety, we conclude that at the moment there is no reason to approve e-cigarettes as a safe alternative to tobacco smoke.

Design: an observational study was carried out by the technicians of the Prevention department from October 1st to October 17th 2008. The observers had to record sex of the driver and of the passengers, their presumed ages, verify if drivers or passengers were smoking, and if there were any children on board.
Objective: to identify the most suitable marker for monitoring ETS inside a moving car, and to verify the efficacy of window opening to reduce ETS pollution inside the car.
Design: experimental pilot study. SSETTING AND PARTICIPANTS: monitoring of ETS markers in a moving car.
Aims And Background: Since 2004, the Antismoking Center of the National Cancer Institute of Milan has rewarded those who have been ex-smokers for longer than a year with a "former smoker" pin and a diploma. We investigated firstly whether these rewards contributed to maintain smoking withdrawal, secondly, which one of these was more appreciated and why, and thirdly, how they may have influenced the ex-smokers' perception of smoking and how this was reflected on those surrounding them (i.e.

Aim Of The Study: to compare PM1, PM2,5 and PM10 levels in and outside the restricted area before and after the enforcement of the charging scheme.
Methods: PM1, PM2,5 and PM10 exposures were measured by means of pre-calibrated portable laser-operated particle analyzers.
