Summary: This study utilized an unmanned aerial vehicle and smart sensors to record vertical profiles of particulate matters, carbon dioxide, and formaldehyde in a rural area of southern India. The data revealed a decrease in air pollutant concentration with increasing height, with pollutants being more strongly influenced by location and meteorological parameters rather than height. Meteorological analysis suggested that transport through advection and convection played a significant role in the vertical distribution of air pollutants.

Summary: In the last decade, reducing carbon dioxide emissions in the transport sector, including the marine sector, has become a strategic development direction. Increased air pollution is a major cause of premature deaths worldwide. Although many methods provide adequate information about pollution levels, there is room for improvement to avoid major errors. Traditional methods are expensive or require a large amount of data and human resources for accurate evaluation. Artificial neural networks (ANNs) and other machine learning methods are widely used to address these issues. While many ANN models have been developed for ship pollution evaluation in ports and nearby cities, there is a lack of research on ANN usage for individual ship pollution or ship plume evaluation. This study attempts to fill this gap by developing an ANN model that combines various data sources to evaluate an individual ship's plumes.

Summary: Evidence from a nationwide cohort study showed a significant association between first-trimester PM1 exposure and maternal blood pressure and hypertensive disorders of pregnancy (HDP). Each 10 mg/m³ increase in first-trimester PM1 was associated with a 1.696 mmHg increase in systolic blood pressure (SBP) and a 1.056 mmHg increase in diastolic blood pressure (DBP), as well as an 11.4% higher odds for HDP. These associations were stronger among older participants (>35 years), those with longer education (>17 years), or those with higher household annual income (>400,000 CNY). Further research is needed for better health management of HDP and the implementation of environmental policies.

Summary: Epidemiological evidence shows that air pollutants are closely related to the occurrence and mortality of cardiovascular diseases. This study explored the association between long-term exposure to air pollutants and changes in cardiac function and structure in Chinese adults. The results showed that exposure to five pollutants (NO2, O3, PM1, PM2.5 and PM10) was associated with decreased left ventricular systolic function and increased pulses. Additionally, four pollutants were associated with decreased left ventricular diastolic parameters and increased cardiac structural parameter. Overall, chronic pollutant exposure is strongly associated with impaired left ventricular function in Chinese adults.

Summary: The intensity and frequency of wildfires are increasing globally. The long-term impacts of non-occupational wildfire exposure on human health have not been systematically reviewed. This study conducted a systematic review of 36 studies and found that non-occupational wildfire exposure was associated with mortality, morbidity, mental health disorders, shorter height in children, reduced lung function, and poorer general health status. However, there is still limited high-quality evidence with quantitative analysis on this topic, and further studies are needed to fill the knowledge gaps.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
