“…Piper betel leaves and areca nut are the main components in a betel quid. The concentration of As in Piper betel leaves have been determined by Al-Rmalli et al [6], and in areca nut by Signes-Pastor et al [90]. In our previous study, As and Se in both betel quids [8] and baked clay [7] were comprehensively investigated.…”

Abstract. Millions of people in Bangladesh are exposed to high concentration of the toxic element arsenic (As) through drinking water and consumption of foods. It has also been reported that Bangladeshis have a low intake of the essential element selenium (Se), which is known to be important as an antioxidant and has been suggested to counteract the toxicity of As. We report here on total intake of As and Se in a Bangladeshi population, based on inductively coupled plasma mass spectrometric (ICP-MS) analysis of a range of Bangladeshi foods. The total daily intake of As and Se from foods was estimated to be 74.2 and 87.7 µg/day, respectively. If As from water, used for drinking and cooking rice, is included the TDI increases to 385 µg of total As per day. An important finding of our study, contrary to suggestions given in other reports, is that the Bangladeshi diet does not appear to be deficient in Se and this may explain why the blood Se concentrations in Bangladeshis is similar to the USA population. This requires further investigation and detailed dietary and human biomonitoring studies on the Bangladeshi population should be conducted. Rice and fish were the main sources of dietary As and Se for Bangladeshis. Leafy vegetables could also be a significant contributor of high concentration of As in the Bangladeshi diet. The flesh and eggs of Hilsha (Tenualosa ilisha) species of fish were found to contain particularly high levels of total arsenic (range 0.77-6.15 mg/kg) although this is likely to be dominated by the non-toxic organoarsenic species.

The EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) assessed the risks to human health related to the presence of arsenic in food. More than 100,000 occurrence data on arsenic in food were considered with approximately 98 % reported as total arsenic. Making a number of assumptions for the contribution of inorganic arsenic to total arsenic, the inorganic arsenic exposure from food and water across 19 European countries, using lower bound and upper bound concentrations, has been estimated to range from 0.13 to 0.56 µg/kg bodyweight (b.w.) per day for average consumers, and from 0.37 to 1.22 µg/kg b.w. per day for 95 th percentile consumers. Dietary exposure to inorganic arsenic for children under three years of age is in general estimated to be from 2 to 3-fold that of adults. The CONTAM Panel concluded that the provisional tolerable weekly intake (PTWI) of 15 µg/kg b.w. established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) is no longer appropriate as data had shown that inorganic arsenic causes cancer of the lung and urinary bladder in addition to skin, and that a range of adverse effects had been reported at exposures lower than those reviewed by the JECFA. The CONTAM Panel modelled the dose-response data from key for providing consumption information and calculating exposure, the partners of the EFSA project on the "Individual food consumption data and exposure" coordinated by Ghent University (Department of Public Health, University Hospital, Ghent University, Belgium), and RIKILT (Institute of Food Safety, Wageningen, The Netherlands) for the accessibility of the exposure assessment tools. 4 Table of contents shows now the fourth level of subheadings. 5 An error in the interpretation of the total number of the population in the study of Rahman et al. (2006a) was discovered (Table 41). The BMDL was recalculated and as a consequence it was not considered a potential reference point. The text in the opinion, Table 43 and Appendix were revised accordingly. In addition, the header of the "total number of cases" was replaced by "total number of individuals" in Tables 40-42 and the erroneous units were corrected to µg/L in the text below SUMMARYArsenic is a metalloid that occurs in different inorganic and organic forms, which are found in the environment both from natural occurrence and from anthropogenic activity. The inorganic forms of arsenic are more toxic as compared to the organic arsenic but so far most of the occurrence data in food collected in the framework of official food control are still reported as total arsenic without differentiating the various arsenic species. The need for speciation data is evident because several investigations have shown that especially in seafood most of the arsenic is present in organic forms that are less toxic. Consequently, a risk assessment not taking into account the different species but considering total arsenic as being present exclusively as inorganic arsenic would lead to a considerable overestimation of the health risk rel...

“…Ancak, kozalaklı bitki türleri arasında olan Douglas Göknarının (Pseudotsuga menziesie) gövdesinde ve iğnelerinde As birikimi nispeten yüksektir [70]. As derişimi sebzeler, baharatlar ve tahıllar gibi ürünlerde düşüktür [71]. Sulama suyunda As derişiminin artması ile pirinç bitkisinin kök, gövde ve kabuktaki As derişimleri önemli ölçüde arttığı ve bitki boyu, tane verimi, dolu tane sayısı, tane ağırlığı ve kök biyokütlesinin önemli ölçüde azaldığı belirlenmiştir [72].…”

GirişArsenik (As) ile kirlenmiş yeraltı suları içme ve kullanma suyu olarak kullanılmasının yanında, sulama suyu olarak da kullanılmaktadır. As içeren su ile sulanan bitkiler, doğrudan insanlar tarafından tüketilmekte veya bu bitkilerin otcul hayvanlar tarafından tüketilmesi ile besin zinciri yoluyla insanlara ulaşmaktadır. Özellikle As ile kirlenmiş toprak ve yeraltı suyunun bulunduğu bölgelerde yaşayan insanlar arseniği bünyelerine beslenme yoluyla (su, bitki ve hayvansal gıda) almaktadır. En yüksek güvenli As alım seviyesi (içme suyundan ve besinlerden) orta yaştaki bir erkek için 220 mg/gün olarak tanımlanmıştır [1].İçme suyunda, As derişiminin kısıtlanması ile As giderimine yönelik araştırma sayısında artış olmasına rağmen ülkemizde, içme ve kullanma suyu kaynaklarında, As kirliliği araştırmaları oldukça sınırlı sayıdadır. Atropojenik (yapay) yollarla sular, As kirlenmesine maruz kalırken, jeotermal kaynaklı suların kullanımı ile de su kaynaklarında As kirlenmesi belirlenmiştir. Doğal ve yapay yollarla As kirlenmesine maruz kalan toprak ve sulama sularının tarımsal amaçlı kullanımı ve etkileri hakkında ülkemizde çalışma bulunmamaktadır.Hayvan beslenmesinde temel gıda maddeleri olan hayvan yemi ve suyun kalitesi hakkında araştırmalar oldukça sınırlıdır. Hayvansal ürünlerde (et, sakatat ve süt) biriken kirleticiler (özellikle ağır metaller) besin zinciri yoluyla insanlara
