Abstract

ABSTRACT Arsenic (As) in rice is a crucial public health concern because it is a human carcinogen. This study was conducted to determine the actual As concentrations and estimate the probable range of As in rice. The status of As accumulation in rice was also determined. White (n=154) and brown (n=54) rice samples were collected over three crop years. The concentrations of As (total, bioaccessible and inorganic) were determined. The total As concentrations in white (0.088–0.295 mg/kg) and brown (0.119–0.517 mg/kg) rice were approximately 58.8% and 57.4% higher than the Codex standards, respectively. However, the bioaccessible and inorganic As in both types of rice were lower than the standards for both rice types. Regarding the classifications of As accumulation (low, normal, high and unusually high), the actual As concentrations found in the rice samples were either in the normal range or a high concentration of As.

泰国商业白米和糙米中总砷、生物可及性和无机砷积累的概率估计和现状

大米中的砷(As)是一个重要的公共卫生问题，因为它是一种人类致癌物。本研究旨在测定水稻中砷的实际浓度，并估计砷的可能范围。测定了砷在水稻体内的积累状况。白米(n=154)和糙米(n=54)样本是在三个作物年中收集的。测定了总砷、生物可及砷和无机砷的浓度。白米(0.088 ~ 0.295 mg/kg)和糙米(0.119 ~ 0.517 mg/kg)的总砷含量分别比国际食品法典标准高出58.8%和57.4%。然而，两种水稻的生物可达性和无机砷含量均低于两种水稻的标准。就砷积累的分类(低、正常、高、异常高)而言，实际样品中砷的含量要么在正常范围内，要么处于高浓度。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
