Phthalates and the substitute plasticizer DINCH belong to first group of priority substances investigated by European Human Biomonitoring Initiative (HBM4EU) answer policy-relevant questions safeguard an efficient science-to-policy transfer results. internal exposure levels were assessed using two data sets from all regions Israel. The collated existing human biomonitoring (HBM) (2005-2019). second consisted new generated in harmonized "HBM4EU Aligned Studies" (2014-2021) on children...
Human biomonitoring (HBM) is a critical tool for assessing chemical exposure in populations and informing public health policies. This study aimed to prioritize substances the development of national HBM program Latvia, addressing need systematic evaluation chemicals local context. Initially, 318 were reviewed, which 130 shortlisted assessed using an adapted Hanlon methodology. Substances based on their significance, hazardous properties, characteristics, relevance, interest. The results...
Considering the multitudes of people who spend their time working indoors in public premises and workplaces, it is worth knowing what level exposure to natural radioactive radon gas, second most widespread dangerous carcinogen for lung cancer development after cigarette smoking. This state-level study covered territory Latvia conducted 941 measurements with Radtrack2, placed 4-6 months companies, educational institutions, medical care etc. The found that 94.7% samples did not exceed national...
Currently, nanoparticles are widely present in the environment and being used various industrial technologies. Nanoparticles affect immune functions, causing different responses. The aim of current study was to evaluate several cytokines, interleukin (IL)-1b, IL-6, IL-8, tumour necrosis factor-a (TNF-α), interferon-γ, adhesive molecule sICAM-1, macrophage inhibitory protein 1a (MIP1a) secretory immunoglobulin A, nasal lavage fluid peripheral blood healthy subjects exposed workplace...
Exposure to radon gas in households presents serious health risks, including an increased likelihood of lung cancer. Following the COVID-19 pandemic, change individual habits has led more time spent indoor environments with remote activities; thus, need raise awareness air quality dwellings and mitigate exposure inhabitants emerged. This study investigated concentrations Latvian dwellings. RadTrack2 passive detectors were deployed a representative sample across 106 municipalities Latvia (98%...
Computer work is characterized by sedentary static workload with low-intensity energy metabolism. The aim of our study was to evaluate the dynamics skin surface temperature in hand during prolonged computer mouse under different ergonomic setups. Digital infrared imaging right forearm and wrist performed three hours continuous (measured at start every 15 minutes thereafter) a laboratory controlled ambient conditions. Four people participated study. Three setups were tested on days...
Background and objectives: Despite global warming, the climate in Northern Europe is generally cold, large number of deaths due to non-optimal temperatures likely cold temperatures. The aim current study investigate association between all-cause mortality, as well cause-specific Tallinn Riga North-Eastern Europe. Materials Methods: We used daily information on from state death registries minimum November March over period 1997-2015 2009-2015 Riga. relationship temperature mortality was...
Organic solvents as chemical risk factors of the work environment in different branches industry and possible impact on workers' health The aim our study was to investigate organic Latvia during 1998-2006 evaluate worker according exposure index. conditions were studied 116 enterprises industries Latvia. analysis 1790 measurements showed that have degrees probability health. levels workplaces differ. More than half surveyed (56.7%) had a low solvent level, 25.2% it medium, 18.1% high. most...
Background and objectives: Progressing climate change is accompanied by a worldwide increase in the intensity, frequency, duration of heat wave events. Research has shown that waves are an emerging public health problem, as they have significant impact on mortality. As studies exploring this relationship scarce for Latvia, study aims to investigate short-term associations between all-cause mortality well cause-specific mortality, during summer months (May-September) Riga. Materials Methods:...
Inhalation is the main route of exposure to airborne pollutants. To evaluate safety and assess risks occupational hazards different testing approaches are used. 3D airway epithelial tissues allow mimic conditions in vitro, generates human-relevant toxicology data, allows elucidate mode action Gillian3500 pumps were used collect particulate from woodworking metalworking environments. EpiAirway model half working day (4 h), full (8 3 exposures Tissue viability was assessed using an MTT assay....
Abstract The aim of this study was to determine public perception chemical pollution and environmental management problems in Riga, Latvia, obtain possible solutions these problems. This is a qualitative where data obtained by organizing focus group interviews. A total 3 groups were held with 18 participants taking part. first consisted adults living apartments, the second – houses, third students; all respondents live Riga city or its peri-urban area. results have shown that main defined...
The Multiple Path Particle Dosimetry (MPPD) model is computer software that estimates and visualizes the deposition, clearance, retention of particles in respiratory tract systems humans, rats, other species. mathematical provides a broad spectrum settings input options. This research aims to explore MPPD concept determine deposition fraction (DF), retained mass human (HRT) based on geometric mean diameter (GMD) concentration (MC) particulate matter (PM) emitted during 3D printing process....
Possible hazards of work environment in metal processing industry Latvia The aim this study was to investigate risk factors the Latvian using database Laboratory Hygiene and Occupational Diseases Institute Safety Environmental Health, Rīga Stradiņš University. During period between 1996 2005, 703 measurements were made metalworking enterprises. In Latvia, approximately 2.4% workforce is involved industry. Physical (noise, lighting, vibration) chemical (abrasive dust, welding aerosol...
This study aims to observe variations in temperature, relative humidity, and carbon dioxide concentrations university classrooms without mechanical ventilation throughout the day. Over three days, two Riga Stradiņš University, equipped solely with natural ventilation, were evaluated for indoor air quality. Observations recorded using Aranet4 sensor during actual sessions varying numbers of occupants, periods marked by window operations. The parameters compared established quality guidelines....
The scientific community is increasingly focusing on indoor air quality (IAQ) more than ever, driven by on-going research and fresh perspectives including development of 3D technologies. Exposure dose (EDa) resulting from inhalation pollutants emitted printers were calculated in this study. consideration emissions based experimental data, primarily sourced reviewed literature. However, also includes some values, excluding the background levels these pollutants. Experiments conducted using...
The usage of ultrasonic diffusers in indoors has raised concerns regarding their potential health effects, mostly due to the lack research on matter. This study’s aim was analyse effect distilled water, tap and water with essential oils droplets from an diffuser number particle matter microbiological contamination indoor air under laboratory conditions during summer winter seasons. most common species throughout all experiments were Gram+ Aerococcus viridans Micrococcus luteus, accounting...

Airborne particulates present a potential hazard to health in variety of indoor workplaces, from offices the manufacturing floor. Dust and aerosols are two most common occupational risk factors workplace worldwide. It is very important understand when it sufficient describe dust exposure only by given mass concentration that particles could be nanosized range air even for brief exposures, such as welding aerosols. The main objective was assess total nanoparticle concentrations selected...
Abstract The world’s leading indoor air quality guidelines provide for the identification of certain parameters with a specific limit value based on latest empirical measurements, however, most them do not have legal coverage and are voluntary. This leads to unequal assessment quality, because there is an identifiable difference between values set out in various guidelines. And these would be related results obtained during experimental activities application interpretation their effects...
