Summary: Occupational exposure during waste sorting is associated with various health outcomes. This study compared the impact of work in fully automated waste sorting plants (AWSP) versus manual waste sorting plants (MWSP) on personal exposure to bioaerosols and related health effects. The results showed that workers at AWSP had lower exposure levels to inhalable dust, thoracic dust, and endotoxins compared to MWSP, but higher levels of fungal fragments, fungal spores, and actinobacterial spores. Microbial DNA exposure varied within and between types of waste sorting plants. Exposed workers also reported more common health symptoms compared to the unexposed control group.

Summary: The study focused on exposure assessment to bacterial aerosols and organic dust in waste sorting plant. The waste reloading plant was found to be the most contaminated with anaerobic bacteria, while the control room had the lowest levels. The presence of anaerobic bacteria, including clostridia, was significantly affected by microclimate parameters.

Summary: This study assesses the risks of plastic debris in settled house dust and highlights the serious impact and polymer hazard of microplastics. Polyethylene and polypropylene are the predominant types of plastic found, and humans are at a higher risk of exposure through ingestion, particularly infants.

Summary: Six phthalates were measured in settled dust on different indoor surfaces in 30 university dormitories. The detection frequencies for most of the phthalates were high, except for one. The study found that phthalate levels were higher in bedside dust than on table surfaces, suggesting a nonuniform distribution in the sleep environment. The simulation showed that the daily intake of one phthalate was the highest among the targeted compounds, and the contributions of daytime and sleeping time exposures to total phthalate exposure were roughly equal.

Summary: This study evaluated the accuracy of different interpolation methods using data from 6 aerobiological sampling stations. The moving mean interpolation method had the highest success rate, especially when considering risk classes. Errors were greater during periods of high concentration oscillations and gaps longer than 5 days. A new Variation Index based on the behavior of the pollen/spore season was developed to estimate potential errors before interpolation.

Summary: This study assessed the impact of Asian dust on human health and the environment by examining particulate matter, trace elements, and bacteria. The results showed that the concentration of particulate matter during Asian dust days was on average 3.5 times higher than non-Asian dust days. Elements from the Earth's crust and anthropogenic sources were identified as major contributors to coarse and fine particles. The study also found that the study area was severely polluted during Asian dust days.

Summary: This study investigated settled house dust (SHD) samples collected from 106 houses in Seoul and Gyeonggi Province, Korea, and found various chemical and biological contaminants in the dust, with the highest concentrations detected for organophosphate flame retardants, phthalates, alternative plasticizers, and trace metals. The study also identified significant associations between the concentrations of contaminants in the dust and factors such as the type and number of electronic appliances and combustion activities, while ventilation, vacuum cleaning, and wet cleaning or dry mopping were found to significantly reduce the levels of contaminants in the dust.

Summary: The study investigated the emission, sorption, and migration of organophosphorus flame retardants (OPFRs) from different sources to settled dust. It was found that dust with lower organic content and smaller size tended to absorb more OPFRs, but different types of dust did not significantly affect OPFRs emission into chamber air from the same source. The partitioning between dust-air favored less volatile OPFRs, while emission from sources favored volatile chemicals.

Summary: This study investigated the characteristics of airborne archaea in Beijing during springtime, revealing soil as the primary source for releasing archaea into the environment. It was found that air quality and sandstorms can impact the abundance of airborne archaea, and dispersal-related neutral processes play a crucial role in shaping the structure of the archaeal assembly.

Summary: This study proposes a mechanism for detoxifying endotoxins by engineering a dephosphorylation reaction using a synthetic nanozyme. The synthesized CeO2 effectively catalyzed the breakdown of P-O bonds in endotoxins, resulting in the attenuation of toxicity. Additionally, the CeO2 column exhibited a significantly higher treatment capacity compared to commercial resins.

Summary: This study investigates the use of electrostatic dust cloths, called E-Cloths, to study the accumulation of microorganisms and endotoxin on workers' clothes. The results show that E-Cloths can effectively measure the accumulation of bacteria and fungi, primarily from the work environment and not the workers' skin.

Summary: This study investigated the potential human exposure to airborne microorganisms, including MRSA, in a pigeon exhibition in Denmark. The results showed high concentrations of fungi, bacteria, and endotoxin in the air, with concentrations up to 200 times higher than outdoor references. The bacteria found in the exhibition were mainly species found in pigeon coops, indicating that pigeons are the sources of exposure. The presence of airborne MRSA highlights the importance of considering this environment as a potential place of exchange of resistant bacteria between animals and humans.

Summary: This study aimed to investigate whether serum levels of C-reactive protein (CRP) and serum amyloid A (SAA) were associated with personal exposure to endotoxin in wastewater treatment plant workers. The results showed significant correlations between CRP and both endotoxinLimulus and endotoxinrFC. SAA was also significantly associated with endotoxinLimulus. Therefore, it can be concluded that airborne endotoxin exposure has a negative impact on the health of wastewater treatment plant workers.

Summary: This study aimed to quantify current exposure levels of inhalable dust, endotoxin, and microorganisms among recycling workers. The results showed that production workers had significantly higher levels of exposure compared to administrative workers. Workers handling paper or cardboard had the highest exposure levels. Temperature did not affect exposure levels, but there was a tendency towards increased exposure to bacteria and fungi with higher temperatures.

Summary: In this study, we investigated the microbial exposure in nursing homes in Denmark. The results showed that personal exposure to microbes varied depending on the profession, with higher concentrations found in staff members involved in care and nursing tasks. We also found some multi-drug resistant isolates, indicating a potential risk for antimicrobial resistance transmission in these settings.

Summary: This study assessed microorganisms in personal inhalable work air samples from waste workers and found that bacterial and fungal concentrations varied significantly between waste sorting plants. A portion of the identified species were classified as human pathogens, and there were correlations between concentrations of certain fungi and self-reported adverse symptoms in exposed workers. The combination of culture-based methods and next generation sequencing contributed to the risk assessment of occupational exposure in waste sorting.

Summary: This cross-sectional study investigated the exposure of workers in drilling waste treatment plants to harmful substances such as airborne dust, bacteria, and fungi. The results showed that some workers were exposed to high levels of endotoxin, bacteria, and fungi, with exposure levels depending on the treatment technique. The drilling waste contained large concentrations of bacteria, and elevated concentrations of airborne bacteria were found near drilling waste basins. Additionally, several pathogenic bacterial and fungal species were detected. Therefore, drilling waste treatment plants pose potential risks to the health of workers.

Summary: This study investigated whether nursing home staff members are exposed to MRSA and assessed their knowledge and compliance with infection hygiene guidelines. Results showed that although staff members were not colonised with MRSA, MRSA was detected in some facilities. Staff members expressed concerns about spreading MRSA and improvement suggestions included enhancing availability of protective equipment and education to reduce worry.
