Summary: The popularity of plant-based food products has grown in response to the increasing demand for plant foods. This study analyzed the total arsenic content and its species in plant-based beverages purchased in Poland. The research validated a method for analyzing arsenic using high-performance liquid chromatography combined with inductively coupled plasma mass spectrometry.

Summary: This study utilized a combination of high-performance liquid chromatography and inductively coupled plasma mass spectrometry (HPLC-ICP-MS) to separate and quantify six arsenic species. The method demonstrated high sensitivity and accuracy, with limits of detection ranging between 0.14-0.29 ng/mL. Spike recovery experiments on rice samples validated the method's applicability to complex matrices, with recovery results ranging between 93 and 109%. Triplicate measurements on all spiked samples recorded percent relative standard deviation values below 10%, indicating the reliability and precision of the method.

Summary: Quantitative, rapid, selective and sensitive methods were developed to determine the total arsenic and six arsenic compounds in seafood. The methods involved the use of quadrupole inductively-coupled plasma mass spectrometry for total arsenic measurement, microwave-assisted extraction for arsenic species isolation, and ion-exchange chromatography coupled with ICP-MS for compound separation and quantification in one chromatographic run. The proposed methods are relatively simple, time- and cost-efficient.

Summary: A novel HPLC-ICP-MS arsenic speciation methodology was developed using ammonium acetate, applicable to six arsenic species. The method covered the most predominant species in toxicology field and addressed typical problems from traditional methods. Chromatographic and detector optimization ensured low LOQs for each species, making it useful for sub ng mL(-1) arsenic exposure assessments.

Summary: This study evaluated the potential health risks of arsenic in food supplements containing algae or cyanobacteria, indicating that certain products may pose health risks for specific population groups. Further research on the toxicity of AsSugars and development of limits for arsenic species in food supplements is suggested.

Summary: Arsenic is a well-known carcinogenic and toxic element that is present in the environment in both inorganic and organic forms. The identification and determination of arsenic species are important due to the varying toxicity of these compounds. A sensitive and optimized method using HPLC/ICP-MS was developed for the determination of inorganic arsenic and relevant organic arsenic compounds. The method was validated and successfully applied to various food matrices, revealing significant concentrations of arsenic in seaweed, rice, cereals, legumes, and plant-based foods for infants and young children. These findings contribute to the assessment of overall arsenic exposure and the establishment of maximum limits.

Summary: An automatic MSPE method combining MGO-based magnetic nanomaterial with HPLC-ICP-MS for arsenic speciation was developed, achieving automatic preconcentration and separation/determination of arsenic species with low LODs and high precision. The method was validated by analyzing Certified Reference Materials and recovery analysis of arsenic species in various samples, showing potential for routine monitoring of arsenic species in environmental waters and biological fluids.

Summary: This study quantified important elements and assessed health risks associated with rice consumption. Analysis of twelve different rice varieties revealed varying levels of metals such as As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, Sr, U, and Zn. The highest Estimated Daily Intake (EDI) value was reported for Zn from Kekulu Samba, while the highest Cancer Risk (CR) value was reported for Cd from red raw rice. The Madathawalu rice recorded the highest Target Hazard Quotient (THQ) value.

Summary: The distribution of Se and Hg in different protein fractions extracted from muscle tissues of tuna, swordfish, and salmon (wild vs. farmed) was investigated for the first time. The study revealed that Se and Hg were associated with proteins of specific molecular weights, with differences observed between farmed and wild salmon. Additionally, Se speciation studies showed SeMeSeCys as the primary selenium species found in the proteins analyzed.

Summary: Rice grains were found to have higher levels of total arsenic compared to other crops. Arsenite (As(III)) was found to be twice as high as arsenate (As(V)) in polished and brown rice. The accumulation of arsenic between the husk and the endosperm was identified as the main source of arsenic in rice bran.

Summary: This study aimed to investigate the influence of different irrigation methods on the speciation of arsenic in rice and measure the concentrations of As(III), As(V), DMA, and MMA in different rice genotypes. The results showed that the concentrations of As(III) and DMA were roughly equal in rice irrigated with continuous flooding, only As(III) was found in rice irrigated with periodic saturation, and As(V) was predominantly present over As(III) in rice irrigated with sprinkler irrigation. Organic arsenic species were below the limits of detection in rice irrigated by intermittent methods. Principal component analysis also revealed significant differences in arsenic speciation as a function of rice genotype.

Summary: A simple and efficient method for the determination of highly toxic arsenic species using noncovalently aminated silica was proposed. The method allows for the effective preconcentration of arsenic anionic species from aqueous solutions, with separate preconcentration and determination of As(V) and As(III) at pH 5.

Summary: An analytical method was developed to confirm the presence of elemental selenium (Se(0)) in selenized yeasts using HPLC-ICP-MS and single-particle ICP-MS. The study found Se(0) to represent 10-15% of total Se in the yeasts. While both methods were able to detect Se(0), reliable quantitative results were not obtained.
