Ideally, personal exposure measurements are collected using techniques that record an individual’s direct exposures. Though this type of data is preferred, it is often lacking. In this study, we tested whether a robot could be programmed to simulate human use of spray products and then used in place of human subjects for generating air concentration data. A robot was programmed to simulate human use of a fabric crafts protector (FCP) and a glass cleaning (GC) product. While the robot used these products, air sampling data was collected to estimate VOC concentrations. The sampling data was summarized and then compared to air concentration data found in the literature while humans used similar products. In this study we successfully programmed a robot to mimic human use of two spray products. Average VOC concentrations were 1.57 ppm for FCP spraying and 0.17 ppm for GC spraying and wiping. Air sampling data were found to be within the range of data reported in the literature. This study demonstrates the ability to use robots to simulate human exposures. It offers a systematic, efficient method for generating exposure data where gaps exist. This data can be used to validate or enhance models and improve health and safety risk assessments used for public health protection.","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past 70 years, there has been a dramatic increase in human exposure to both natural and synthetic chemicals. Endocrine disruptors are chemicals that may interfere with the hormonal system and thereby produce harmful effects in both humans and wildlife. Under the European REACH regulation, endocrine disruptors are identified as substances of very high concern alongside chemicals known to cause cancer, mutations and toxicity to reproduction. Similarly to carcinogens or mutagens, reprotoxic substances may have serious and irreversible effects also on workers’ health. Therefore, occupational exposure to reprotoxic substances should also be regulated under the same directive on the protection of workers from carcinogens or mutagens at work (Directive 2004/37/EC). Occupational exposure limit values have been set for 12 widely used substances in the new directive 2022/431/EC, and therefore validated exposure assessment methods should be made available. The health surveillance is requested for workers exposed to these substances, that is the assessment of the health status of an individual worker based on exposure to specific substances during work. Therefore, cooperation with obstetrician, gynaecologist and other reproductive health professionals is needed, for the assessment of male and female fertility status. On the other side clinicians should always ask women of childbearing age about occupational exposures as legal exposure limits for most workplace chemicals are not designed to protect against harm to a pregnancy or the developing fetus.","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A pilot study on two treatment plants, showed presence of human bacterial- and fungal pathogens in the drilling waste and showed a need for this larger study. Methodology The study included 7 different plants across Norway, thus encompassing most of the industry. 435 personal full-shift analyses, 26 bulk samples and 123 stationary short-time samples of microorganisms were collected. Viable bacterial and fungal species were identified with MALDI-TOF, and bacterial and fungal DNA with ddPCR. The biofilm formation potential was also measured using an Epoch microplate spectrophotometer. Results Even though mean exposure was low, some workers were exposed to high levels of endotoxin (207 EU/m3), bacteria (3.8x104 CFU/m3 and 9.8x104 DNA copies/m3) or fungi (1.4x107 CFU/m3 and 3600 DNA copies/m3). The drilling waste contained a high number of bacteria (102 to 1010 CFU of bacteria/mL) and pathogens in risk class 2 were found in all plants. The biofilm formation potential varied between the different plants. Conclusions Despite moderate exposure levels, certain work tasks, job titles, areas, and techniques, were associated with elevated levels of microorganisms and endotoxin. Human pathogens were present in the drilling waste, the workers can be exposed via the air and potentially via splashes.","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It measures particle mass by utilizing beta attenuation. However, due to the high deviation of beta particles per second, commercial beta gauges have a high response time. That means achieving real-time monitoring is challenging. This study aims to improve the beta gauge’s detection limit(LOD) and response time(TR) for real-time monitoring. To reduce external environmental interference, aerosol generation system was established in laboratory to generate stable challenge particle size and distribution. The commercial beta gauge was used to evaluate the effects of the sampling area, sampling number, and smoothing time(TS). Lambert Beer’s law was used to convert the beta intensity into mass concentration per second, evaluating the beta gauge’s TR, S/N ratio, and LOD. By adjusting TS from 5 to 75 min, TR reaches from 0.3 to 60 minutes. At daily average PM2.5 of 35 μg/m3, the SD of readings decreases from 175 to 3.2 μg/m3. At quantitative standard (S/N ratio=10), when the sampling area is reduced from 2 to 0.4 cm2, the required TS is shortened by 33%. When the sample number is increased to 6, the required TS can be shortened by 60%. The LOD is about 12 μg/m3 with TS of 75 minutes. By increasing the sample number to 6, it can be achieved 1.5 μg/m3. To optimize its response time, the smoothing method can be utilized. To improve the stability of beta gauge measurement and achieve a lower LOD, it is recommended to reduce the sampling area and increase the number of samples.","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141531689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These are underestimates of the burden of occupational exposure and disease. We are not effectively preventing occupational disease and related fatalities through the classical approaches to occupational safety and health and risk management. There is an urgent need for alternate strategies to prevent occupational illness. Total Worker Health® (TWH®), introduced by NIOSH in 2011, offers an approach for consideration that could serve as a model across geographies and sectors to improve worker wellbeing, mitigation of risk, and ultimately, prevention of occupational disease and related fatality. This presentation will include the recent global estimates of non-communicable, occupational disease published by the World Health Organization and International Labour Office in 2021, and a review of the International Council on Mining and Metals’ Critical Control Management (CCM) process. TWH® will be defined and issues related to advancing worker wellbeing will be introduced. The other “Totals” and their relationships to TWH will be explained. The presentation will highlight the challenges in applying the CCM approach to critical risks associated with overexposure to chronic occupational health hazards such as silica and other carcinogens. In these intersecting topic areas, occupational hygienists and other OEHS professionals as exposure scientists can have meaningful input into prevention strategies and programs and improved worker health outcomes. Collaborative opportunities offering sustainable solutions will be introduced and discussed.","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In some countries such as the US (OSHA) and Belgium, this is included in legislation: law enforcement tests the TWA lower confidence limit LCL=TWA*(1-U) exceedance of the OEL while employers test the TWA upper confidence limit UCL=TWA*(1+U) compliance with the OEL. International standards such as EN482 and ISO-20581 help establish U, UCL and LCL. Current exposure assessment strategies promoted by IOHA members, such as AIHA (2015), EN689 (2018) and BOSH/NVvA (2022), ignore measurement uncertainty. This may be due to historical work (Nicas, 1991), which shows that in similar exposure groups (SEG), lognormal long-term daily environmental variability exceeds U. However, Monte-Carlo simulations, which will be shown in this lecture, show that the influence of U on the lognormal, one-sided upper confidence limit of the 95th percentile (UTL95,##%) can be significant in occupational hygiene practice with sample sizes often smaller than n=6. Also in the last decade, several strategies promote a simplified screening/preliminary test (French Code du Travail, EN689:2018 §5.5.2, BOSH/NVvA 2011/2022). In these tests, the highest result (TWAmax) of 3 to 5 measurements is compared with the OEL or with a defined fraction f(OEL). In line with the above, these TWAmax tests should use TWAmax*(1-U) ≤ f(OEL) for compliance and TWAmax*(1+U) &gt; OEL for exceedance. IOHA member organisations are advised not only to align the numerical test schedules for compliance, but also to include measurement uncertainty in the OEL tests.","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An alternative test slide has now been developed using state of the art nano-metre fabrication technology, and is known as the Pickford Phase Contrast Test Slide, and manufactured by PhaseSlides.
