Introduction Geogenic arsenic poses one of the most significant public health challenges, affecting 140 million people across 70 countries in the world (WHO, 2018). In particular, inorganic arsenic (iAs) is a group 1 carcinogen as advised by the International Agency for Research on Cancer (IARC). Also, iAs is included in the list of top 10 chemicals, or group of chemicals, of significant public health concern by the World Health Organisation (WHO 2016). Arsenic exposure affects almost every organ in the human body and produces a range of health effects, including skin lesions, cancer, diabetes and lung diseases (NRC, 2014).

Introduction Originating from either geological sources or anthropogenic activities, arsenic (As) has been widely recognized as a human carcinogen since at least the 1950s (Currie, 1947; Hueper, 1967; Polya and Middleton, 2017), with its more toxic species, inorganic arsenic (iAs), being predominant or important in soil, water, air, rice and some other foods, including vegetables, and some fruit juices (Chen et al., 2011a; Diane et al., 2013; Currier et al., 2014; Molin et al., 2015; Yanez et al., 2015; Bae et al., 2017).

Ubiquitously present in the environment (Tchounwou et al., 2004; Culioli et al., 2009; Bundschuh et al., 2012; Huda et al., 2014), individuals may be exposed via oral (ingestion), inhalation, dermal contact, and even parenteral routes (US Department of Health Human Services et al., 2007). In addition, the association of iAs exposure with cardiovascular disease (CVD) risks has also been reported by several groups. 2. 2.1.

Seventy rice samples collected from the Red River Delta and mining zone activity were analysed. Concentration of heavy metals and arsenic in rice was analysed after appropriated sample digestion using internal or external calibration curves. The mean concentration (mg kg−1 dried weight) of the analysed elements in rice samples decreased on the order of Mn (19.268) > Fe (13.624) > Zn (8.163) > Cu (3.138) > Ni (0.384) > Cr (0.296) > Co (0.279) > As (0.115) > Cd (0.111) > Pb (0.075) > Hg (0.007) > Se (<LOD).

Mercury, a highly toxic element, has been only found in rice samples collected in the mining activity zone (frequency detection 14.5% of total samples).

For this reason, this cereal should form part of a balanced diet. Rice is also gluten-free and is, therefore, an alternative to cereals containing gluten for those who suffer from a gluten intolerance. INT. J. ENVIRON. RES. PUBLIC HEALTH 08/01/20 Arsenic Concentrations and Dietary Exposure in Rice-Based Infant Food in Australia. 1. Introduction Arsenic (As), a naturally occurring metalloid, is widely distributed in air, soil and groundwater in both organic and inorganic forms. Current knowledge indicates that organic forms of As have relatively low toxicity, but inorganic As (iAs) is a non-threshold human carcinogen [1].

In South-East Asia (e.g., Bangladesh, West Bengal and Vietnam) where groundwater is a major source of As contamination; it has adversely affected tens of millions of people [2]. In addition to exposure through As-contaminated drinking groundwater, people can also be exposed to As through food ingestion, particularly rice [3,4]. FOOD SAFETY NEWS 05/05/20 Researchers find arsenic in rice risk for UK infants. Scientists have found half of rice varieties they tested exceeded maximum arsenic limits for young children in the United Kingdom. A team at the University of Sheffield’s Institute for Sustainable Food found 28 of 55 rice samples sold in the U.K. contained levels of arsenic that exceeded European Commission regulations for rice for infants or children under the age of five.

The U.K. follows European Commission regulations so that inorganic arsenic concentrations must be below 0.20 milligram per kilogram in white (polished) rice and less than 0.25 mg per kg in brown (unpolished) rice. However, the concentration in rice used for infant food production or direct consumption is set at a maximum of 0.1 mg per kg. Potential risk for infants Results showed brown rice had higher levels of inorganic arsenic than white or wild rice because it contains the bran – the outer layer of the grain. UNI-BEYREUTH-DE 11/02/20 Risk or opportunity for rice cultivation? Bayreuth researchers discover new arsenic compounds in rice fields. University of Bayreuth, Press release No. 016/2020, 11 February 2020 University of Bayreuth researchers, together with scientists from Italy and China, have for the first time systematically investigated under which conditions, and to what extent, sulphur-containing arsenic compounds are formed in rice-growing soils.

To date, these thioarsenates have not been taken into account in assessments of the health effects of rice consumption. In the journal "Nature Geoscience" the scientists present their results and identify the urgent need for research with a view to protecting consumers from health risks.

This study is aimed at investigating a suitable method for rice sample preparation as well as validating and applying the method for monitoring the concentration of total arsenic, cadmium, and lead in rice by using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Various rice sample preparation procedures were evaluated. The analytical method was validated by measuring several parameters including limit of detection (LOD), limit of quantification (LOQ), linearity, relative bias, and repeatability. Regarding the sample preparation, recoveries of spiked samples were within the acceptable range from 89.3 to 98.2% for muffle furnace, 94.2 to 103.3% for heating block, 81.0 to 115.0% for hot plate, and 92.8 to 108.2% for microwave. Validation parameters showed that the method fits for its purpose, being the total arsenic, cadmium, and lead within the Brazilian Legislation limits. 1. 2. 2.1. 2.2. 2.3. 2.3.1. 2.3.2. 2.3.3. 2.3.4. 2.3.5. 2.4. 2.5. 2.6. 3.

ENVIRONMENTAL TOXICOOGY 10/08/17 Environmental behavior, potential phytotoxicity, and accumulation of copper oxide nanoparticles and arsenic in rice plants. Rice has served as an important human food source for more than 8000 yr and has played an essential role in the process of Asian civilization and urbanization 1. Historically, rice has been and continues to be the main food source for half of the world's population, because of its easy transportation and storage and relatively short cooking time 2, 3. Globally, 42% of the 2868 kcal energy consumed daily by the average person comes from cereal crops in which rice is the dominant grain 4. Rice also serves as a mainstay or supplementary food for people on restricted diets.

For example, rice replaces simple carbohydrates, meat, and dairy products for lactose‐intolerant people or for those on a macrobiotic diet because of its low percentage of gluten and a slow and continuous release of glucose into the blood 5.

Les autorités de sécurité alimentaire au Danemark ont déconseillé mercredi aux parents les gâteaux au riz et le lait de riz pour les enfants, en raison de la concentration en arsenic. Le riz contient naturellement de l'arsenic inorganique, et «les personnes consommant quotidiennement des aliments avec de l'arsenic inorganique courent un risque accru de cancer», ont-elles expliqué sur leur site internet. Elles ont appelé les parents à être «particulièrement attentifs» à la consommation des enfants, en raison de leur poids, et à éviter les boissons au riz et le lait de riz, ainsi que de donner des céréales au riz soufflé chaque jour. Le Danemark a lancé de nouveaux tests portant sur d'autres produits à base de riz pour déterminer leur concentration en arsenic inorganique, comme les nouilles de riz. Les résultats de ces analyses doivent être publiés en juillet. La présence d'arsenic dans le riz attire de plus en plus l'attention. 1.

Between March and May 2013, three multi-country outbreaks of hepatitis A virus (HAV) infection were reported through the Epidemic Intelligence Information System for Food- and Water-borne diseases (EPIS-FWD) of the European Centre for Disease Prevention and Control (ECDC). The aim of this work is to put these outbreaks into a European Union (EU) and European Economic Area (EEA) perspective and highlight opportunities for improving detection and investigation of such outbreaks. Although HAV outbreaks are not unusual in the EU/EEA, having three large food-borne multi-country outbreaks declared within three months is an unexpected event, particularly when at least two of these outbreaks are associated with frozen berries. Surveillance and early warning for hepatitis A virus infection in the European Union and countries of the European Economic Area Hepatitis A is a self-limiting viral disease caused by hepatitis A virus (HAV).
