Accumulation of five heavy metal ions by five species of wood-rotting basidiomycetes during a 9-day cultivation was studied. Contents of Cd, Cu, Pb, and Zn were measured using ICP-MS; the amount of mercury was determined directly in solid samples using the Advanced Mercury Analyser. A standard operation procedure for the sample preparation and determination of metal content was developed and validated. Presence of Cd, Cu, Hg, and Pb decreased the accumulation of zinc by the fungi. The basidiomycete Pycnoporus cinnabarinus exhibited the highest metal binding capacity of all fungi tested.

Iron is the most abundant transition metal in the brain and is essential for brain development and neuronal function; however, its abnormal accumulation is also implicated in various neurological disorders. The olfactory bulb (OB), an early target in neurodegenerative diseases, acts as a gateway for environmental toxins and contains diverse neuronal populations with distinct roles. This study explored the cell-specific vulnerability to iron in the OB using a mouse model of intranasal administration of ferric ammonium citrate (FAC).

This study sought to validate the external calibration curve (CAL) method for iodine analysis in 26 selected foods and then to compare the test result with the isotope dilution mass spectrometry (IDMS). Iodine was extracted by tetramethylammonium hydroxide (TMAH) and determined by ICP-MS using CAL and IDMS methods. The results showed that iodine determination using the IDMS method had higher precision than the CAL method (LOD of the method were 0.

This study aims to delineate the levels of Cd exposure in maternal blood, placenta, and cord blood, and to explore the association between Cd levels and the risk of preeclampsia (PE), as well as its potential impact on fetal growth among affected individuals. A case-control study was performed at the First Hospital of Shanxi Medical University, involving 373 pregnant women diagnosed with PE and 485 controls. Cd was measured in maternal blood, placenta, and cord blood using ICP-MS.

An analytical quality by design-guided LC-ICP-MS method for simultaneous arsenic speciation analysis in HEK-293 cells was optimized and validated. Initially, critical method variables (CMVs) were identified to achieve the targeted critical quality attribute (CQA) of the analytical target profile (ATP). Based on knowledge and risk assessments, formic acid (X), citric acid (X), and pH (X) were studied for their effect on method responses such as resolutions (Y1, Y2) and retention time of As(V), As(III) and DMA (Y3, Y4, and Y5) using central composite design (CCD).

This work estimates Michaelis-Menten kinetics parameters for nutrient transport under varying flow rates in the soft roots of Indian mustard () using a plant fluidic device. To find the metallic components within the roots, inductively coupled plasma mass spectrometry (ICP-MS) analysis was performed. The flow rate-dependent metabolic changes were examined using Raman spectral analysis.
