Microplastic Migration and Transformation Pathways and Exposure Health Risks.

Plastics play a crucial role in modern life, but improper use and disposal have resulted in microplastics becoming widespread in the environment, raising significant concerns about both the environment and human health. Extensive research has explored the transformation mechanisms, bioaccumulation, ecological impacts, and health risks associated with microplastics. The present review first analyzes the migration, transformation, and degradation pathways of microplastics on a global scale, and then synthesizes current knowledge on the types, sources, and migration pathways of microplastics in soil, atmosphere, and aquatic environments, emphasizing transformation mechanisms like photo-aging and microbial degradation, and detailing their ecological and human health impacts.

Understanding the composition of mercury (Hg) in the atmosphere is important for confirming its sources and to preventing and reduce the production. To explore the morphological distribution characteristics of wet Hg concentrations in Xi'an Shaanxi Province, China, total Hg (THg), dissolved Hg (DTHg), reactive Hg (RTHg) and particulate-bound Hg (PTHg) (Hg insoluble in water) were measured at 72 precipitation in Xi'an from September 2020 to July 2022, and their average concentrations were 3.035 ± 3.

Middle ear barotrauma (MEBT) is the most common complication in providing hyperbaric oxygen therapy (HBO). This study explored the impact of altering the shape of the time-pressure curve with the aim of reducing the occurrence of MEBT and optimizing the HBO experience during the pressurization process. Four distinct mathematically derived protocols-Constant Pressure Difference (CPD), Constant Volume Difference (CVD), Constant Ratio (CR), and Inverted Constant Ratio (ICR)-were investigated using computer simulations on a simple ear model.

Background: Sexual harassment (SH) and Gender discrimination (GD) faced by medical students have been neglected areas of study in India. Only a few recent studies could be found, despite frequent media reports on SH and GD. This study aimed to assess the attitudes and perceptions of sexual harassment and gender discrimination and evaluate the forms of SH and GD experienced by them.

In 2020, the largest continuous wetland area on the planet, the Brazilian Pantanal, experienced an unprecedented fire that affected the entire ecosystem. Our goal was to elucidate the effects of ash presence following the fire events. We quantified the impact of ashes, collected in four Conservation Units, on soil, water, and atmosphere.
