“…The dried samples were ground using a grinder (BJ-800A, Deqing Baijie Electric Co., Ltd., Huzhou, China) and then passed through a 60-mesh sieve. According to the previous studies [ 40 , 41 ], 0.1 g rice powder was placed into a crushing tube (pre-placed zirconium beads, Φ 0.15 mm, 1.5 g) and 1 mL of 1:5000 ( v : v ), and then Triton-100 solution was added. After sealing, the sample was placed in a grinder (DS1000, Hubei Xinzongke Viral Disease Engineering Technology Co., Ltd., Wuhan, China) and ground 3 times at 5500 rpm for 15 s. After grinding, the tube was placed in a shaker (NMYJ-12, Taizhou Nomi Medical Technology Co., Ltd., Taizhou, China) and shaken for 120 s. The above sample preparation can be finished within 7 min.…”

In this work, a direct solid sampling device based on modified graphite furnace electrothermal vaporization (GF-ETV) with inductively coupled plasma mass spectrometry (ICP-MS) was established for the simultaneous detection of trace selenium and cadmium in rice samples. A bypass gas was first designed in GF-ETV to improve the device’s analytical sensitivity and precision. The ashing and vaporization conditions, the flow rates of the Ar carrier and the bypass gases of ICP-MS were all investigated. Under the optimized conditions, the limits of detection (LODs) for Se and Cd were 0.5 μg kg−1 and 0.16 μg kg−1, respectively; the relative standard deviations (RSDs) of repeated measurements were within 8% (n = 6). The recoveries of Cd and Se in rice samples were in the range of 89–112% compared with the microwave digestion ICP-MS method, indicating good accuracy and precision for the simultaneous detection of Se and Cd in rice matrix. The whole analysis time is <3 min without the sample digestion process, fulfilling the fast detection of Se and Cd in rice samples to protect food safety.

“…The dried samples were ground into powder by a grinder (BJ-800A, Deqing Baijie Electric Co., Ltd., Huzhou, China) and then sieved through 60 mesh. According to the previous studies ( 28 , 29 ), 0.05 g celery, spinach, carrot or tea sample was placed in a crushing tube with 8 zirconium balls (ɸ2.0 mm) and mixed with 1 mL of 0.5% (v:v) Triton X-100 (PerkinElmer, Waltham, MA, United States) solution; for grain sample, ɸ1.5 mm zirconium balls were employed. After sealing, the crushing tube was put into a grinder (DS-100, Hubei Xinzongke Virus Engineering Technology Co., Ltd., Wuhan, China) and shaken for 3 times with 15 s each time at 5500 rpm.…”

Rapid, sensitive and simultaneous determination of trace multi-elements in various plant food samples such as grain, oilseed, vegetable and tea is always a challenge thus far. In this work, a rapid determination method for Se, Cd, As and Pb in food samples by inductively coupled plasma mass spectrometry (ICP-MS) using slurry sampling electrothermal vaporization (SS-ETV) was developed. To improve the analytical sensitivity and precision as well as eliminate the memory effect, a gas turbulator line and signal delay device (SDD) were for the first time designed for the graphite furnace (GF) ETV coupled with ICP-MS. The signal acquisition parameters of ICP-MS, ashing and vaporization conditions, and the flow rates of carrier gas and gas turbulator were investigated for Se, Cd, As and Pb in food samples. Under the optimized conditions, the limits of determination (LODs) for Se, Cd, As and Pb were 0.5 ng g−1, 0.3 ng g−1, 0.3 ng g−1 and 0.6 ng g−1, respectively; the limits of quantification (LOQs) for Se, Cd, As and Pb were 1.7 ng g−1, 1.0 ng g−1, 1.0 ng g−1 and 1.9 ng g−1, respectively; linearity (R2) in the range of 1 to 4,000 ng g−1 was >0.999 using the standard addition method. This method was used to analyze 5 CRMs including rice, tea and soybeans, and the concentrations detected by this method were within the range of the certified values. The recoveries of Se, Cd, As and Pb in plant food matrices including grain, oilseed, celery, spinach, carrot and tea samples were 86–118% compared to the microwave digestion ICP-MS method; and the relative standard deviations (RSDs) were 1.2–8.9% for real food sample analysis, proving a good precision and accuracy for the simultaneous determination of multi-elements. The analysis time was less than 3 min, slurry preparation time < 5 min without sample digestion process. The proposed direct slurry sampling ICP-MS method is thus suitable for rapid and sensitive determination of Se, Cd, As and Pb in food samples with advantages such as simplicity, green and safety, as well as with a promising application potential in detecting more elements to protect food safety and human health.

“…This explains why the concentrations obtained by ICP-SFMS are obviously higher than the ionic fractions. The crustal particles are dissolved with acids, and any fine particles present below an aerodynamic diameter of 8µm act as a solution aerosol in the spray chamber and plasma and are atomized in the plasma of the ICP-SFMS (Goodall et al, 1993;Tong and Guo, 2019).…”

Abstract. The study of aerosol in high mountain regions is essential because particulate matter can play a role in altering the energy balance of high mountain regions, and aerosols can accelerate glacier melting in high mountain areas by darkening the ice surface, reducing its reflectivity (albedo). Studying aerosols in high mountain areas provides insights into long-range transport of pollutants, atmospheric dynamics, and climate change impacts. These regions can serve as valuable observatories for studying atmospheric processes. The main aim of this paper is to define the main sources of aerosol over an entire year of sampling at the Col Margherita Atmospheric Observatory (MRG 46° 22’ 0.059’’ N, 11° 47’ 30.911’’ E, 2543 m a.s.l.), a high-altitude background site in the Eastern Italian Alps. Here, we discuss the potential origins of more than one hundred chemical markers (major ions, water soluble organic compounds, trace elements, rare earth elements) using different approaches. Some diagnostic ratios were applied, but source apportionment using Positive Matrix Factorization was used to define the main inputs of PM10 collected at this high-altitude site. Moreover, a characterization of the air masses helped us to confirm the aerosol sources.
