Summary: Introducing species to areas without top-down control can be disastrous for ecosystems. A study on tropical forest-dwelling mammals found that some introduced species became extinct while others experienced population explosions. The lack of top predators on the island contributed to the rapid population growth of certain introduced mammals.

Summary: Atmospheric nitrate and sulfate, major inorganic components of particulate matter, have a significant impact on human health, ecosystem health, and air quality. This study investigated the long-term response of particle chemistry in urban and rural environments in southern New England, an area historically affected by nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions. The results showed that there was a significant urban-rural aerosol chemical composition gradient within a 40 km radius. As anthropogenic influences decreased, the relative contribution of marine and crustal sources increased, affecting the chemistry of fine and coarse particles. Total mass concentrations of chemical species, particularly anthropogenic sulfate and particulate ammonium, decreased dramatically over the ten-year period at both urban and rural sites. However, nitrate concentration increased despite significant reductions in NOx emissions, indicating changes in chemical mechanisms. Furthermore, the decrease in SO2 emissions significantly impacted the atmospheric lifetime and transport distance of particulate ammonium.

Summary: Long-term temperature changes globally drive trends in coastal Marine Heatwaves (MHW) and Sea Surface Temperatures (SST). Analysis of satellite data reveals depressed onshore SST trends in over 2/3 of coastal pixels, correlated with reduced MHW exposure and severity. Models have limited ability to simulate these trends, highlighting the complexity of small-scale coastal ocean-atmosphere feedbacks.

This study utilized polar orbiting satellites to collect data on various air pollutants over Pakistan from January 2005 to December 2021. The results showed high levels of PM2.5, SO2, AOD, CO, and ozone in central Punjab, western Baluchistan, central Sindh, and Khyber Pakhtunkhwa. The study also examined the seasonal variation and correlation between these pollutants, as well as their changing patterns over time in different cities across Pakistan.

Summary: The major factors of wine trade worldwide have shown distinct temporal trends in the past decades. Wine consumption, production, imports, and exports differ according to location and classification of Old World and New World wine markets. This study quantified long-term trends and relationships between these factors using various datasets and statistical methods. The findings reveal decreasing trends of wine consumption and production in Old World countries, while some of the largest wine-consuming New World countries experience significant increases. Around 80% of countries show increasing trends of wine imports, indicating the impact of globalization and growing demand for foreign wine. Overall, per capita wine consumption has significantly decreased, and wine production is strongly dependent on consumption, as well as imports and exports.

Summary: The study investigates the impact of land-sea breezes on the atmospheric transport of organic aerosols in a coastal city in East China. Organic marker compounds showed diurnal/seasonal patterns, with different trends during land-sea breeze periods in early autumn and early spring. The study also found that the aging and reaction pathway of biogenic secondary organic aerosols (SOA) were related to land-sea breezes. Changes in the ratio of monoterpene SOA markers indicated different levels of aging during sea breeze and land breeze periods. The results provide new insights into the chemical composition shift of organic aerosols over coastal areas influenced by land-sea breezes.

Summary: Low molecular weight monocarboxylic acids (LMW monoacids, C1-C10) are the most abundant gaseous organic compound class in the atmosphere. They can contribute to rainwater acidity, particle formation, and secondary organic aerosol production. This paper reviews the distributions of LMW monoacids in different environments, discusses their sources and formation mechanisms, and highlights their importance as cloud condensation nuclei (CCN).

Summary: This study investigated the accumulation of dissolved organic matter (DOM) in seasonal snow and found that the DOM contents increased linearly with accumulation time. Optical properties of snowmelt, such as fluorescence intensity and absorption coefficient, increased exponentially due to the accumulation of terrestrial humic-like fluorophores and soil-derived substances. Fourier transform-ion cyclotron resonance-mass spectrometry revealed the molecular characteristics of DOM, with compounds derived from soil and vascular plants making the largest contribution.

Lu from November 5 to December 10, 2019. The study analyzed the features of CCN and CCN formation at Mt. Lu, and found that aerosol composition plays a larger role than aerosol size in determining CCN activation. The study also observed diurnal variations in CCN and CN concentrations at Mt. Lu, with higher concentrations occurring at midday.

Summary: This study investigated the source, formation, and seasonality of biogenic secondary organic aerosol (BSOA) in Beijing, China from April 2017 to January 2018. BSOA tracers derived from isoprene, monoterpene, and sesquiterpene were measured and showed significant seasonal variations. Isoprene SOA tracers correlated with biomass burning and long-range transport, while sesquiterpene SOA tracer was associated with local biomass burning. These results suggest that BSOA tracers are promising for understanding the source, formation, and seasonality of BSOA.

Summary: Based on field studies in Alaska, it was hypothesized that potassium (K) is scavenged and deposited on the inner wall of the chimney during wood stove burning. Chimney deposit samples were collected and analyzed, revealing that K concentrations were highest in the lower part of the chimney and decreased with height, while levoglucosan (Lev) showed the opposite trend. An anti-correlation was observed between K and Lev in the chimney deposits, indicating that K is largely scavenged as a deposit while Lev is emitted to the ambient air. The K/Lev mass ratios can be used to evaluate the contributions of open fires and domestic wood burning to ambient aerosols.

Summary: The size distributions of chemical species in aerosols collected over Northern Japan were analyzed, showing substantial contributions from anthropogenic sources, sea-salt, and dust particles via long-range atmospheric transport. Oxalic acid was found to be the dominant organic species, followed by malonic and succinic acid. The distribution of dicarboxylic acids in aerosols was consistent with the influence of continental and marine air masses. The results suggest that air masses from East Asia and the surrounding ocean mainly control the abundances of organic aerosols over Northern Japan.

Summary: In this study, we collected PM2.5 and analyzed its composition and stable isotope ratios in Tianjin, China. The results showed higher concentrations of PM2.5, organic carbon, elemental carbon, and water-soluble organic carbon in winter compared to summer. The dominant ions were SO42-, NO3-, and NH4+, with different seasonal variations. Coal and biomass combustion emissions were the major sources of PM2.5 in autumn and winter, while terrestrial and/or marine biological emissions were important in spring and summer.

The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
