Summary: A study sampling springs on Sao Miguel Island in Portugal revealed variations in major-ion and radon (Rn-222) content influenced by geological units, seasons, and hydrochemical characteristics. Springs from Fogo Volcano showed the highest radon concentrations, while those from Furnas Volcano exhibited the lowest levels. Groundwater temperature plays a crucial role in controlling the radon content and can be influenced by the geology and geochemistry of the area.

Summary: The importance of tourism in the Azores' economy has been increasing over the years. However, the COVID-19 pandemic and government measures to control the infection rate have resulted in a significant decline in tourists and a negative impact on the tourism accommodation and restaurant sectors. A survey conducted on Sao Miguel, the largest and most visited island, shows a substantial drop in mean income (78.7% for local accommodation, 74.7% for traditional hotels, and 58.5% for restaurants) and a nearly 60% decrease in occupancy rate in the 2020 tourism high season compared to 2019.

Summary: This study used lichens as bioindicators to compare the impact of agricultural and artificial land uses against forest land use on an oceanic island. The results showed significant elemental enrichment in lichens from agricultural and artificial land uses, with higher levels of bioaccumulation in artificial land use lichens, including toxic heavy metals. By analyzing the elemental concentrations and nitrogen isotopic composition of lichen samples, the study highlights the vulnerability of island ecosystems to anthropogenic impacts, even from relatively small-scale human activities.

Summary: The youngest explosive eruptions of the Sete Cidades volcano in Sao Miguel, Azores, are recorded by small-volume trachytic pyroclastic deposits called the Pepom tephra deposits. These deposits contain crystal-poor to crystal-moderate pumice clasts, as well as dense glassy clasts of similar crystallinity. The dense clasts are likely the result of sintering of fragmented magma at shallow levels in the conduit prior to eruption.

Summary: The structure of the crust and lithospheric mantle of Sao Miguel Island in the Azores Plateau was revealed through seismic profiles. The island consists of 5 crustal layers, with the Moho discontinuity located 15 km below the island. There is a lens-shaped magmatic cumulate at the base of the crust. The island has undergone southwards-directed extensional shear, resulting in uplift, northwards tilting, and landslides. The Sao Miguel Deep Ductile Deformation Zone is a diffuse plate boundary.

Summary: This study aimed to assess the association between chronic obstructive pulmonary disease and occupation. Through cross-sectional data analysis of 28,823 adults aged 40 and above in 34 countries, it was found that working in environments with potential exposure to dusts or fumes was associated with respiratory symptoms but not lung function differences. Therefore, respiratory surveillance should be encouraged among high-risk dusty and fume job workers, especially in low- and middle-income countries.

Summary: This study examined the association between residential greenspace and change in lung function over 20 years in middle-aged European adults. The findings showed that living in more greenspaces was not associated with better lung function, but instead there were slight but consistent declines in lung function parameters. These findings need to be verified in future studies.

Summary: Poverty is strongly linked to increased all-cause and chronic obstructive pulmonary disease (COPD) mortality. However, the impact of poverty on spirometry-defined chronic airflow obstruction (CAO), a key characteristic of COPD, is less understood. Using data from the Burden of Obstructive Lung Disease study, poverty was found to contribute to up to 6% of CAO in individuals over 40 years old. Understanding the relationship between poverty and CAO may provide insights for improving lung health, especially in low and middle-income countries.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
