Summary: This study developed a county-level emission inventory of particles and gases pollution based on field measured emission factors and detailed activity data for the Qinghai-Tibetan Plateau (QTP) in 2019. The emissions from animal dung burning in the QTP have significant impacts on regional and global climate and environment. The major contributors of all pollutants are Gonghe, Qilian, Nyima, and Gangcha Counties in northeast of Qinghai and northwestern Tibet.

Summary: Storing manure can be beneficial for dairy farms in terms of maximizing fertilizer value, reducing costs, and minimizing environmental pollution. However, it also poses the risk of nitrogen loss through ammonia volatilization. This study quantifies ammonia loss from manure stored in a clay pit at a dairy farm and provides valuable information for developing mitigation strategies.

Summary: This study developed a method for the temporal allocation of NH3 emissions from fertilizer application by combining satellite remote-sensing data with ground-station data. A high-resolution dataset for fertilizer application in China was established, and NH3 emission inventories for the three major crops in China were developed. The results showed that fertilizer application and NH3 emissions were highest during the spring and summer months.

Summary: The study found that the spatiotemporal changes in atmospheric NH3 across the entire US are still not thoroughly understood, and ammonia release is related to synthetic N fertilizer use, livestock manure production, and climate factors. The influence of NH3 released from livestock manure during warmer winters contributed to increased annual NH3 concentrations in the Western US. The US Midwest may become an atmospheric NH3 hotspot in the context of future warming due to the strong positive impact of temperature on NH3 concentrations.

Summary: Agriculture is a major contributor to ammonia (NH3) emissions, which have negative impacts on air quality and human health. However, there is still uncertainty regarding the global pattern of NH3 emissions, particularly with regards to specific crops and animals. This study developed an improved agricultural NH3 emissions inventory from 1961 to 2018, revealing that global NH3 emissions averaged at 39.2 Tg N yr-1 and were driven by livestock production (58.4%) and cropland (41.6%). Cattle, rice, maize, and wheat were identified as key contributors to agricultural NH3 emissions. The study also highlighted the shifting hotspots of NH3 emissions from the United States and European Union to China and India in recent years. These findings enhance our understanding of NH3 dynamics in agriculture and provide important insights for the formulation of NH3 pollution prevention and control policies.

Summary: NH3 emissions in China, mostly from livestock production, are associated with high levels of PM2.5 and poor air quality. A study conducted in Sheyang, Jiangsu province, achieved a 16% reduction in emissions through two strategies, with a potential for 42% reduction if fully implemented. The cost benefit analysis showed advantages of centralized manure treatment over in-farm facilities.

Summary: The substitution of mineral nitrogen fertilizer with manure can increase wheat and maize yields, but decrease rice yield. It also leads to lower NH3 volatilization, N2O and NH3 emissions, and N runoff. The loss of Nr is negatively correlated with soil organic carbon content. Factors like N application rate, soil properties, and climate play important roles in N2O and NH3 emissions and N leaching.

Summary: Invasion by nonindigenous species poses a major threat to marine ecosystems, with invasive barnacles occupying a higher percentage in summer. The study found significant correlations between water temperature, salinity, and the distribution of the five barnacle species. Future predictions suggest dominant invasive species in different Korean seas. Monitoring invasive species long-term and understanding their relationship with environmental variables can aid in predicting potential damage caused by invasive species due to environmental changes.

Summary: The study demonstrates that long-term use of glyphosate-based herbicide may have negative impacts on non-target soil organisms, particularly in terms of juvenile production and population age structure. While GBH was found to have no negative effects on adult survival, juvenile production decreased, and the age structure of the population was altered by GBH exposure. Additionally, differences in phospholipid profiles between control and GBH treatments were observed over generations, suggesting potential long-term effects on non-target soil invertebrates.

Summary: Ecological risk assessment based on scientific data is crucial for understanding the causal relationships between chemical pollution and environmental risks. The TRIAD approach, incorporating three lines of evidence (chemical, ecotoxicological, and ecological), was used to assess soil ecological risks in abandoned mine sites. The results showed different levels of risk at different sites and revealed the influence of physicochemical properties of the soil medium on metal bioavailability. This study is significant in reducing uncertainty in ecological risk assessment and providing information for effective decision-making in soil risk management.

Summary: Collembola play significant roles in the soil ecosystem and their phenotypic endpoints can be used as effective bioindicators for soil quality assessment. This study proposed the use of environmental DNA (eDNA) analysis as a tool for identifying Collembola species in soil, which is a more efficient and cost-effective method compared to traditional identification and counting. Standard primer sets for species-specific eDNA analysis were chosen for Allonychiurus kimi, a soil bioindicator species. The primers showed specificity and sensitivity in detecting intra- and extra-organismal eDNA samples, indicating the potential use of eDNA analysis in studying Collembola populations. The results also highlighted the importance of considering environmental factors when analyzing eDNA collected from soil samples.

Summary: This study focuses on the implementation of a gas chromatograph-photoionization detection (GC-PID) analyzer for the continuous monitoring of 1,3-butadiene (1,3-BD) levels in urban and industrial atmospheres. The study found that the concentrations of 1,3-BD recorded by the GC-PID analyzer were comparable to those obtained by active sampling, and the concentration peaks showed consistency in values and time slots. In the test of urban atmospheres, the results showed that the concentrations of 1,3-BD were related to prevailing wind direction and activities in the petrochemical zone, while other factors had minor effects on the distribution of this pollutant.

Summary: This study investigated the temporal profile and composition of PM10 over a 14-month period, and found significant variations between different seasons. The highest concentrations of PM10 were observed in summer and winter, exceeding the national limits. Water-soluble ionic species and n-alkanes contributed to the PM10 mass, with the highest concentration in winter and the lowest in the monsoon season. The ion balance study revealed a strong correlation between anion and cation charge equivalents, indicating their main contribution to PM10. The main sources of PM10 components were identified using statistical correlation, regression, and principal component analysis.

Summary: The impact of bicycle lane designs on cyclist exposure to air pollution is a significant concern. This study found that in the city of Medellin, Colombia, the sections without dedicated bicycle lanes had the highest PM2.5 exposure and inhaled dose. Cyclists had higher PM2.5 exposure and inhaled dose during morning peak hours compared to evening peak and off-peak hours. Segregated cycling lanes on the sidewalk can considerably lower PM2.5 exposure and inhaled doses for cyclists.

Summary: This study investigates the relationship between temperature inversions (TI) and aerosol vertical distribution in China. The results show that TI frequency, inversion strength (Delta T), and TI height (TIH) exhibit similar seasonal patterns across different regions in China. NC has a significantly higher TI frequency during summer, possibly due to the heating effect of black carbon aerosol. Aerosol optical depth (AOD) above the TIH is higher in spring and summer, indicating the presence of aerosol high-level transport over mainland China during these seasons. The study also finds that a strong inversion can suppress surface aerosols below the TI, but in regions with strong atmospheric stability, aerosols tend to accumulate above the TIH. These findings are valuable for understanding aerosol transport.
