The Effect of Ambient Air Pollution on Severity of COVID19: Hospitalisation and Death

The advent of a new Corona virus, SARS-CoVi-2, causing COVID-19, which first began in Wuhan, China, and then spread worldwide, has created a global public health crisis [1]. The sudden and far-reaching pandemic has raised many immediate questions. A very important goal of public health is to identify environmental factors that affect the spread and severity of the disease. Air pollution is one of the most well-known causes of long-term inflammation, which ultimately leads to increased immune system hyperactivity [2]. Air pollution is one of the leading causes of death and is estimated to play a role in nearly 5 million premature deaths worldwide in 2017 alone. Numerous scientific studies have linked air pollution to a variety of health concerns, including premature death in patients with heart or lung disease, non-fatal heart attacks, irregular heartbeats, and severe asthma [3]

COVID-19: the Austrian experience

This short paper reports on the Austrian experiences with the Corona pandemic in the first quarter of 2020. In the beginning Austrian experts neglected the threat but a cluster in a skiing resort including international visitors served as a wake-up call and quickly after that strict and successful measures were applied. The paper proceeds describing the development of SARS-CoV-2 PCR testing and upgrading of testing facilities in Austria. The Austrian Agency for Health & Food Safety (AGES) played a leading role in this process. International cooperation and information exchange were fundamental to the successful implementation of specific and sensitive laboratory methods

Dust and Cobalt Levels in the Austrian Tungsten Industry: Workplace and Human Biomonitoring Data

In general, routine industrial hygiene (IH) data are collected not to serve for scientific research but to check for compliance with occupational limit values. In the preparation of an occupational retrospective cohort study it is vital to test the validity of the exposure assessment based on incomplete (temporal coverage, departments) IH data. Existing IH data from a large hard metal plant was collected. Individual workers’ exposure per year and department was estimated based on linear regression of log-transformed exposure data for dust, tungsten, and cobalt. Estimated data were back-transformed, and for cobalt the validity of the estimates was confirmed by comparison with individual cobalt concentrations in urine. Air monitoring data were available from 1985 to 2012 and urine tests from the years 2008 to 2014. A declining trend and significant differences among departments was evident for all three air pollutants. The estimated time trend fitted the time trend in urine values well. At 1 mg/m3, cobalt in the air leads to an excretion of approximately 200 µg/L cobalt in urine. Cobalt levels in urine were significantly higher in smokers with an interaction effect between smoking and air concentrations. Exposure estimates of individual workers are generally feasible in the examined plant, although some departments are not documented sufficiently enough. Additional information (expert knowledge) is needed to fill these gaps

Mass calibration and Relative Humidity compensation requirements for optical portable particulate matter monitors : the IMPASHS (Impact of smoke-free policies in EU Member States) WP2 preliminary results

Better knowledge of particulate matter (PM) concentrations needs portable, reliable, user friendly, low cost, real time mass analyzers of PM2.5 and PM10. Optical Particle Counters (OPC) measuring mass have manufacturer calibration specific gravity “K” factor referred to polystyrene latex particles which are completely different than those of the real world, therefore they require specific calibrations. Measurements are also subject to Relative Humidity (RH) heavy interference.Fundação para a Ciência e a Tecnologia (FCT

Potential health risk of endocrine disruptors in construction sector and plastics industry: a new paradigm in occupational health

Endocrine disruptors (EDs) belong to large and diverse groups of agents that may cause multiple biological effects associated with, for example, hormone imbalance and infertility, chronic diseases such as diabetes, genome damage and cancer. The health risks related with the exposure to EDs are typically underestimated, less well characterized, and not regulated to the same extent as, for example, carcinogens. The increased production and utilization of identified or suspected EDs in many different technological processes raises new challenges with respect to occupational exposure settings and associated health risks. Due to the specific profile of health risk, occupational exposure to EDs demands a new paradigm in health risk assessment, redefinition of exposure assessment, new effects biomarkers for occupational health surveillance and definition of limit values. The construction and plastics industries are among the strongest economic sectors, employing millions of workers globally. They also use large quantities of chemicals that are known or suspected EDs. Focusing on these two industries, this short communication discusses: (a) why occupational exposure to EDs needs a more specific approach to occupational health risk assessments, (b) identifies the current knowledge gaps, and (c) identifies and gives a rationale for a future occupational health paradigm, which will include ED biomarkers as a relevant parameter in occupational health risk assessment, surveillance and exposure preventioninfo:eu-repo/semantics/publishedVersio

The questionnaire design process in the European Human Biomonitoring Initiative (HBM4EU)

This document was created for the HBM4EU project. HBM4EU has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 733032. The Swiss participation in this European Program is funded by the Swiss State Secretary for Education Research and Innovation (SERI).Background: Designing questionnaires is a key point of epidemiological studies assessing human exposure to chemicals. The lack of validated questionnaires can lead to the use of previously developed and sub-optimally adapted questionnaires, which may result in information biases that affect the study’s validity. On this ground, a multidisciplinary group of researchers developed a series of tools to support data collection within the HBM4EU initiative. The objective of this paper is to share the process of developing HBM4EU questionnaires, as well as to provide researchers with harmonized procedures that could help them to design future questionnaires to assess environmental exposures. Methods: In the frame of the work package on survey design and fieldwork of the HBM4EU, researchers carried out procedures necessary for the development of quality questionnaires and related data collection tools. These procedures consisted of a systematic search to identify questionnaires used in previous human biomonitoring (HBM) studies, as well as the development of a checklist and evaluation sheet to assess the questionnaires identified. The results of these evaluations were taken into consideration for the development of the final questionnaires. Results: The main points covered by each of the sections included in HBM4EU questionnaires are described and discussed in detail. Additional tools developed for data collection in the HBM4EU (e.g. non-responder questionnaire, satisfaction questionnaire, matrix-specific questionnaire) are also addressed. Special attention is paid to the limitations faced and hurdles overcome during the process of questionnaire development. Conclusions: Designing questionnaires for use in HBM studies requires substantial effort by a multidisciplinary team to guarantee that the quality of the information collected meets the study’s objectives. The process of questionnaire development described herein will contribute to improve the harmonization of HBM studies within the social and environmental context of the EU countries.European Union's Horizon 2020 research and innovation programme 733032Swiss State Secretary for Education Research and Innovation (SERI

Secondhand Smoke Exposure in Hospitality Venues in Europe

BACKGROUND: Although in the last few years some European countries have implemented smoking bans in hospitality venues, the levels of secondhand smoke (SHS) in this occupational sector Could still be extremely high in most countries. OBJECTIVE: The aim of this study, was to assess exposure to SHS in hospitality venues in 10 European cities. METHODS: We included 167 hospitality venues (58 discotheques and pubs, 82 restaurants and cafeterias, and 27 fast-food restaurants) in this cross-sectional study. We carried Out fieldwork in 10 European cities: Vienna (Austria), Paris (France), Athens (Greece), Florence and Belluno (Italy), Galway (Ireland), Barcelona (Spain), Warsaw and Lublin (Poland), and Bratislava (Slovak Republic). We measured vapor-phase nicotine as an SHS marker. RESULTS: We analyzed 504 samples and found nicotine in most samples (97.4%). We found the highest median concentrations in discos/pubs [32.99 mu g/m(3); interquartile range (IQR), 8.06-66.84 mu g/m(3)] and lower median concentrations in restaurants/cafeterias (2.09 mu g/m(3); IQR, 0.49-6.73 mu g/m(3)) and fast-food restaurants (0.31 mu g/m(3); IQR, 0.11-1.30 mu g/m(3)) (p < 0.05). We found differences of exposure between countries that may be related to their smoking regulations. Where we sampled smoking and nonsmoking areas, nicotine concentrations were significantly lower in nonsmoking areas. CONCLUSIONS: Hospitality venues from European cities without smoking regulations have very high levels of SHS exposure. Monitoring of SHS on a regular basis as well as a total smoking ban in hospitality sector would be needed
