“…Arsenic toxicity differs on the basis of its chemical form, inorganic arsenic generally being more toxic than organic arsenic. Among inorganic arsenic forms, arsenite is more toxic than arsenate (Yang et al, 2016). The United States Environmental Protection Agency (EPA) reported that the LD 50 values for arsenite, arsenate, MMA, DMA, AsC, and AsB are 15-42 mg/kg, 20-200 mg/kg, 700-1800 mg/kg, 1200-2600 mg/kg, 6500 mg/kg, and 10,000 mg/kg, respectively (Abernathy, 2003).…”

“…However, most of the arsenic exposure occurs orally via diet, indicating that the oral route is the predominant path of exposure (Chung et al, 2014). Arsenic contained in groundwater and surface water accumulates in agro-fishery products, thus entering the body (Yang et al, 2016). The Korea Food and Drug Administration (KFDA, 2018) reported that fish accounted for the highest proportion (35.2%) of the total arsenic exposure via food, followed by seaweed (20.0%), molluscs (10.1%), crustaceans (9.6%), grains (9.1%), shellfish (4.7%), processed food (3.7%), kimchi and pickled foods (2.8%), and fruits (1.5%).…”

“…Therefore, the JECFA withdrew the previous PTWI and has suggested no new PTWI value for inorganic arsenic. The JECFA noted that more accurate information regarding inorganic arsenic content of foods is needed owing to its consumption, to improve the assessment of dietary exposure to inorganic arsenic species (Yang et al, 2016). Therefore, the objective of this study was to develop a method to reduce inorganic arsenic content and measure total, inorganic, and organic arsenic content in hijiki.…”

This study aimed to evaluate the reduction of total, organic, and inorganic arsenic content in Hizikia fusiforme (hijiki). Initially, the six most common arsenic compounds in hijiki and its organs were evaluated, among which only arsenate and arsenobetaine were detected. Thereafter, the entire plant, including the stalk and leaves, was treated with heat and NaCl solution, individually and in combination. Heating at 90 °C for 5 min significantly reduced arsenic content in hijiki by approximately 33-80%. Treatment with NaCl solution significantly reduced arsenic content in hijiki, except for arsenobetaine content in the stalk. Combinatorial treatment further decreased arsenic content by more than 5-20%. In conclusion, consumption of hijiki after boiling at 90 °C and soaking in 2% NaCl solution reduces the intake of inorganic arsenic by consumers.

“…The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has shown a large fluctuation in inorganic arsenic content in a sample, and there is still insufficient verification of the analysis method. It was decided that these problems should be improved (Yang et al 2016;Choi et al 2010). The solid phase extraction (SPE) method has been considered as an alternative to simplify the separation process.…”

Feasibility of quantitative inorganic arsenic speciation at the parts-per-trillion level using solid phase extraction and femtosecond laser ablation inductively coupled plasma mass spectrometry

Toxicity of arsenic compounds depends on the chemical structure as well as the concentration. Thus, separation of the toxic arsenic species should precede the quantification for the accurate toxicity assessment. Ion chromatography inductively coupled plasma mass spectrometry (IC-ICP-MS) has been the most popular method for separation and quantification of toxic arsenic species. However, the method requires complex instrument, elaborate sample preparation, and long analysis time. In this work, toxic inorganic arsenic species in water was separated by the simple solid phase extraction (SPE) using a strong anion-exchange membrane filter, and then the membrane filter was analyzed by femtosecond laser ablation inductively coupled plasma mass spectrometry (fs-LA-ICP-MS). The pH value of the sample was adjusted to 4 using ammonium hydroxide and phosphoric acid for the complete separation of the toxic inorganic arsenic from the other organic arsenics. The linear dynamic range was from 0.5 to 1000 μg/kg, and the correlation coefficient was 0.99989. The recovery efficiency was 96‑106%. The detection limit of the inorganic arsenic was 0.028 μg/kg. Our results indicate that SPE-fs-LA-ICP-MS provides enough analytical performance to analyze the toxic inorganic arsenic in water at the level of parts per trillion using the simple separation method and the rapid laser ablation sampling.

There is an increasing concern over arsenic (As) contamination of paddy soil and rice with regard to food safety. This study was conducted to investigate total and inorganic As concentration in one hundred husked and polished rice samples collected at the non-contaminated paddy soil in Korea. Arsenic species in rice samples were extracted using 1% nitric acid (HNO 3) with a microwave oven and were measured using high performance liquid chromatography coupled with inductively coupled plasma-mass spectrometry. Mean concentrations of total As in husked rice and polished rice were 0.18 and 0.11 mg kg −1 , respectively. Also, average inorganic As concentrations in husked rice and polished rice were 0.11 and 0.07 mg kg −1 , respectively. These levels are lower than the standard guideline value 0.35 and 0.2 mg kg −1 for inorganic As in husked and polished rice recommended by Codex Committee on Contaminants in Foods and Ministry of Food and Drug Safety, respectively. The mean of the inorganic As ratio for the total amount of As was 0.65 and 0.67 for husked rice and polished rice, respectively, and the range was from 0.08 to 1.0. For health risk assessment, the average value of cancer risk probability was 9.24×10 −5 and ranged from 2.30×10 −5 to 1.90×10 −4. Therefore, human exposure to As through dietary intake of surveyed rice samples might considered to be a low health risk.
