Article Synopsis
- Aminium ions in atmospheric particles significantly affect new particle formation and haze, with their concentrations varying based on marine and terrestrial sources and changing weather conditions.
- A study in Qingdao analyzed the concentrations of different aminium ions over various seasons, finding higher levels during autumn and winter, with daily peaks in the morning for most ions except TEAH, which peaked later due to oxidation.
- Results indicate that human activities are the main sources of MMAH and DMAH, while TMAH is largely produced from agricultural and marine sources, with unique seasonal patterns influenced by local weather phenomena like sea breezes.
Bioavailable transition trace elements, such as soluble iron (Fes) and soluble manganese (Mns) in aerosols, play a crucial role in atmospheric sulfate formation and marine ecosystems. In this study conducted during the spring of 2017 in Qingdao, a coastal city in Northern China, we applied a combined approach of multiple linear regression (MLR) incorporating the results of positive matrix factorization (PMF) to estimate the solubility of Fe and Mn from various sources. PMF analysis showed that dust was the largest contributor to total Fe (Fe) (45.

The electrode has an immobilized layer of a mixture of D-β-hydroxybutyrate dehydrogenase (HBDH) and nicotinamide adenine dinucleotide (NADH) as sensing material to investigate its electroanalytical properties by means of cyclic voltammetry (CV). The modified electrodes are used for the detection of AcAc and present a linear current increase when the AcAc concentration increases.
