Partitioning gaseous water-soluble organic compounds (WSOC) to the aerosol phase is a major formation pathway of atmospheric secondary aerosols (SOA). However, fundamental mechanism WSOC-partitioning process remains elusive. By simultaneous measurements both gas-phase WSOC (WSOCg) and aerosol-phase (WSOCp) formic acetic acids at rural site in Yangtze River Delta (YRD) region China during winter 2019, we showed that WSOCg campaign dominantly partitioned dry period (relative humidity (RH) <...
Optical characteristics and molecular compositions of brown carbon (BrC) were investigated during winter 2019 at a rural site China with focus on nitro-aromatic compounds (NACs) imidazoles (IMs). The abundance gaseous nitrophenols relative to CO the campaign maximized noontime, being similar O3, while particulate NACs haze periods strongly correlated toluene NO2, suggesting that in region are largely formed from gas-phase photooxidation. Strong correlations IMs dry mass ratio EC/PM2.5...
To understand the chemical evolution of dust in current East Asian atmosphere, chemistry PM2.5 and size-resolved aerosols Shanghai, China, during 2019 storm event was investigated. Our results showed that concentrations SO42- city highly correlated with Ca2+ Na+ due to direct emissions CaSO4 Na2SO4 from upwind deserts. In contrast, event, NO3- linearly NH4+ at a molar ratio close 1:1, both almost entirely stayed coarse particles, suggesting they accumulated on surface as NH4NO3. Based field...
Abstract. NH3 is the most important alkaline gas in atmosphere and one of key species affecting behaviors atmospheric aerosols. However, impact on secondary organic aerosol (SOA) formation remains poorly understood, especially dynamic evolution chemical compositions SOA process. In this study, a series chamber experiments were performed to probe individual common effects NOx toluene through OH photooxidation. The characterized using Aerodyne high-resolution time-of-flight mass spectrometer...
To understand the gas-to-particle-phase partitioning process of water-soluble organic compounds (WSOCs) in atmosphere, we conducted simultaneous measurements gaseous WSOCs and particulate Shanghai during summer 2020. We found that pollution events (PEs) PM2.5 campaign can be classified as sulfate-dominated (SD) or nitrate-dominated (ND) episodes. The coefficients (Fp) ND episodes (0.36 ± 0.04) were 40% higher than those SD (0.25 0.05). These results largely driven by aerosol liquid water...
Abstract Echinoderms are an exceptional group of bilaterians that develop pentameral adult symmetry from a bilaterally symmetric larva. However, the genetic basis in evolution and development this unique transformation remains to be clarified. Here we report newly sequenced genomes, developmental transcriptomes, proteomes diverse echinoderms including green sea urchin ( L. variegatus ), cucumber A. japonicus with particular emphasis on sister earliest-diverged echinoderms, feather star...
Heterogeneous oxidation of SO2 by NO2 on aerosols has recently been found to be one the major formation pathways sulfate in polluted troposphere, but chemical mechanisms and kinetics remain uncertain. By combining lab experiments, theoretical chemistry calculations, field measurements, here we show that is critically dependent anions at air-aerosol aqueous interface. The reaction rate with HSO3- (1.1 × 108-1.6 109 M-1 s-1) more than four orders magnitude larger traditionally held value for...
Abstract. To understand the chemical evolution of aerosols in transport process, chemistry PM2.5 and nitrogen isotope compositions on mountainside Mt. Hua (∼1120 m above sea level, a.s.l.) inland China during 2016 summertime were investigated compared with parallel observations collected at surface sampling site (∼400 a.s.l.). The exhibited a high level mountain foot (MF; average 76.0±44.1 µg m−3) could be transported aloft by anabatic valley winds, leading to gradual accumulation daytime...
Abstract. Mandatory use of low-sulfur fuel according to the global sulfur limit regulation has reduced emissions SO2 and particulate matter (PM) significantly on ships, it also leads a very large uncertainty in volatile organic compound (VOC) emissions. Therefore, an on-board test VOCs from nine typical cargo ships with fuels China was carried out this study. Results showed that emission factor (EFVOCs) varied largely 0.09 3.01 g kg−1 fuel, domestic coastal (CCSs) having highest level,...

The Haima cold seep, which is one of the two active seeps in South China Sea, known for its great ecological importance. seep bivalves are assumed to depend mainly on their bacterial symbiosis survival and growth. However, information diversity, composition, putative function gill-associated dominant dwelling animals remain elusive. Herein, we adopted a high-throughput sequencing 16S rRNA gene amplicons, prediction methods (Functional Annotation Prokaryotic Taxa (FAPROTAX) Phylogenetic...
High-throughput sequencing is a powerful tool used for bivalve symbiosis research, but the largest barrier contamination of host DNA. In this work, we assessed DNA reduction efficiency, microbial community structure, and diversity four different sample pre-treatment extraction methods employed in gill tissue samples. Metagenomic showed average proportions reads belonging to microorganisms retrieved using PowerSoil kit, with differential centrifugation, filtration, HostZERO Microbial kit...
