“…Our result for Pb contamination was higher than the level of 0.039 mg/kg reported by Voica et al (2012) (Rabbani et al, 2015). In Malaysia, Abd Rashid et al (2019) presented an even higher Pb content of 2.19 mg/kg in a small sample of Malaysian, Thai and Pakistani white rice.…”

Our study aimed to quantify toxic metals (Arsenic, As, Cadmium, Cd, Chromium, Cr, Mercury, Hg and Lead, Pb) in rice, determine the factors affecting its contamination, and evaluate the dietary exposure from its consumption in Lebanon and UAE. A market screening was done and subsequently, all the brands (total of 236 samples, with 107 from Lebanon and 129 from UAE) were collected and tested. Inductively Coupled Plasma-mass Spectrometry (ICP-MS) was used. In Lebanon, the average ± standard deviation in samples was 0.24±0.08, 0.29±0.13, 0.34±0.13, 0.15±0.05, and 0.27±0.10 mg/kg for As, Cd, Cr, Hg and Pb, respectively. In UAE, concentrations were 0.18±0.09, 0.07±0.04, 0.23±0.11, 0.17±0.05, and 0.24±0.08 mg/kg for As, Cd, Cr, Hg and Pb, respectively. In UAE, 9, 1, 100 and 69% of samples exceeded the international limits for As, Cd, Hg and Pb, respectively. In Lebanon, 25, 73, 100 and 69% of samples were above limits for As, Cd, Hg and Pb, respectively. No limits were set for Cr for comparison. In Lebanon, for As, brown rice was significantly more contaminated than white and parboiled rice (p=0.02), long rice grains were significantly more contaminated than short/medium grains (p=0.002), and rice brands originating from developed countries were significantly more contaminated compared to those from developing countries (p<0.001). In UAE, for As, packing season, country of origin, collecting same brands at two different times had significant effect (p= 0.011, 0.016, and <0.001, respectively). In Lebanon, for Cd, collecting same brands at two different times and grain size had significant effect (p<0.001). In UAE, for Cd, collecting same brands at two different times had a significant effect (p=0.008). Regarding Cr, in Lebanon, country of origin, grain size, rice type, and time between packing and purchasing had a significant effect (p=0.006, p<0.001, p<0.001 and p<0.001, respectively). In UAE, for Cr, the only statistically significant variable was collecting same brands at two different times (p<0.001). For Hg in Lebanon, grain size and type had a significant effect (p=0.019 and p=0.012, respectively), while collecting same brands at two different times had a significant (p<0.001) effect in both Lebanon and UAE. None of the variables had a significant effect on Pb in samples from Lebanon. For Pb in UAE, statistical significance was observed for collecting same brands at two different times and country of origin (p=0.004 and 0.001, respectively). Exposure levels to Hg from rice were higher than both FAO/WHO and European Food Safety Authority limits were detected in UAE. In Lebanon, exposure levels were not considered alarming for Cd, Cr and Hg, as the Lebanese rice consumption rate is relatively lower than in UAE, despite the high levels of contamination. No provisional tolerable limits are currently set for As and Pb; thus, the observed exposure to both metals could be a cause of concern in both countries. Future studies must assess the effects of handling and cooking to better assess exposure to toxic from rice exposure in both countries.

“…In Vietnam, Chu et al (2021) found that the mean contamination of Vietnamese rice with As was 0.115± 0.049 mg/kg. Another study conducted in Romania found that the mean As contamination in rice was 0.042 mg/kg (Voica et al, 2012). Rabbani et al (2015) reported that As was not detected in any imported or local rice sample in Iran.…”

“…ICP-MS is suitable for biomonitoring of human samples including blood, urine, and hair [105][106][107]. ICP-MS is used in environmental research [108], infant and adult nutrition [66,109,110], as well as the analysis of drugs and pharmaceuticals, medicinal plants and supplements [95]. Furthermore, ICP-MS based multi-elemental monitoring has applications in medicine including toxicology [111], occupational health [76], and is being developed for clinical diagnostics and monitoring [112,113].…”

Elemental metabolomics

Elemental metabolomics is quantification and characterization of total concentration of chemical elements in biological samples and monitoring of their changes. Recent advances in inductively coupled plasma mass spectrometry have enabled simultaneous measurement of concentrations of > 70 elements in biological samples. In living organisms, elements interact and compete with each other for absorption and molecular interactions. They also interact with proteins and nucleotide sequences. These interactions modulate enzymatic activities and are critical for many molecular and cellular functions. Testing for concentration of > 40 elements in blood, other bodily fluids and tissues is now in routine use in advanced medical laboratories. In this article, we define the basic concepts of elemental metabolomics, summarize standards and workflows, and propose minimum information for reporting the results of an elemental metabolomics experiment. Major statistical and informatics tools for elemental metabolomics are reviewed, and examples of applications are discussed. Elemental metabolomics is emerging as an important new technology with applications in medical diagnostics, nutrition, agriculture, food science, environmental science and multiplicity of other areas.

“…Since its introduction ICP-OES and ICP-MS has significantly changed the capabilities of elemental analysis. Today these methods are highly precision and sensitive methods of physicochemical analysis, which are often used for food analysis [4][5][6][7][8]. The success of the measurements and the reliability of the results depends upon the quality of the methods that are developed.…”

The principal goal of present work was to develop a precise method of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method to measure trace toxic elements (Cd and Pb) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) method to measure macro and micro elements (K and Cu respectively) in rice flour, the sample preparation method using a system for microwave-assisted pressure digestion and the preparation of laboratory plasticware. The parameters of the sample preparation method, of the spectrometers and measurement results are given.
