Medicinal plants are widely used in the Kingdom of Saudi Arabia to treat various ailments in the form of folk medicine. Forty four such medicinal plant samples were collected from local markets and evaluated for the presence of 14 elements (Mn, Cr, Co, Ni, Cu, Mo, Al, Pb, Ba, Zn, Ag, Hg, Bi, Cd). Microwave-assisted digestion with inductively coupled plasma-mass spectrometry (ICP-MS) was applied to determine the elemental composition in these medicinal plants. Widespread occurrence of these elements was observed in all plant samples, except for Bi and Co where the lowest mean values of 0.03 ± 0.04 and 0.03 ± 0.15 were observed, respectively. The descending order for mean (μg/g) elemental occurrence observed was as follows: Ba > Al > Zn > Ni > Mn > Ba > Hg > Mo > Cu > Cr > Ag > Cd > Co > Bi, whereas the range for these elements in the 44-medicinal plants was as follows: Pb > Al > Zn > Ni > Mn > Cu > Mo > Ag > Ba > Hg > Co > Cd > Cr > Bi. Pb, Hg and Cd were found beyond the maximum limits in these medicinal plants, while the remaining elements were found well within the range of maximum limits. A number of medicinal plants showed high amounts of these elements. Some plants contained more than one element, such as Foeniculum vulgare Mill (Pb, Hg, Cd), Ricinus communis (Pb, Cd), Vigna radiata (Pb, Cd) and Sesamum indicum (Pb, Hg). The data matrix was validated through the statistical tools of principal component analysis (X2= 160.44, P = .00), Pearson's correlation (P = .01 and 0.05), and K-mean cluster analysis (F = 104.55, P = .00). The findings of the study provide baseline data for the comparative analysis of these medicinal plants, which may help select safe medicinal plants in terms of consumer-based use and its utilisation for the treatment of various ailments.
药用植物在沙特阿拉伯王国被广泛用于民间医学形式的各种疾病治疗。从当地市场收集了44个这样的药用植物样本，并对14种元素(Mn、Cr、Co、Ni、Cu、Mo、Al、Pb、Ba、Zn、Ag、Hg、Bi、Cd)的存在进行了评估。采用微波辅助消解-电感耦合等离子体质谱法(ICP-MS)测定这些药用植物的元素组成。除Bi和Co的最低平均值分别为0.03±0.04和0.03±0.15外，这些元素在所有植物样品中都广泛存在。44种药用植物的平均元素含量(μg/g)由高到低依次为Ba > Al > Zn > Ni > Mn > Ba > Hg > Mo > Cu > Cr > Cd > Co > Bi, Pb > Al > Zn > Ni > Mn > Cu > Mo > Ag > Ba > Hg > Co > Cd > Cr > Bi。铅、汞、镉超标，其余元素均在最大限量范围内。许多药用植物含有大量的这些元素。有些植物含有一种以上的元素，如小茴香(Pb, Hg, Cd)，蓖麻(Pb, Cd)，放射线(Pb, Cd)和芝麻(Pb, Hg)。采用主成分分析(X2 = 160.44, P = .00)、Pearson相关分析(P = .01和0.05)、k -均值聚类分析(F = 104.55, P = .00)等统计工具对数据矩阵进行验证。这项研究的结果为这些药用植物的比较分析提供了基线数据，这可能有助于在消费者使用方面选择安全的药用植物及其用于治疗各种疾病的用途。

ABSTRACT Cd, Hg, and Pb concentrations were investigated in Sardina pilchardus fish. Samples originated from the Atlantic Northeast fishing area 27 and were analysed by inductively coupled plasma optical emission spectroscopy. The aim of the study was to estimate the health impact of consumption, based on the concentrations and calculated exposure for each element. Based on the average total arsenic concentration of 3.26 ± 0.39 mg/kg in the samples, the estimated inorganic arsenic content and calculated PTWI suggested that the samples do not pose a health risk for consumers. Cadmium content of the samples was also not considered hazardous, as both the measured concentrations and PTMI values were below the specified limits. Lead concentration exceeded the maximum limit in 73% of the samples, while calculated average weekly intake was below the recommended level. The measured mercury concentrations exceeded the maximum limit in only 5% of the samples.

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.

ABSTRACT The aim of this study was to develop a convenient, fast, effective and safe analytical method (QuEChERS) to determine 198 pesticide residues in multi-source date palm fruits using gas chromatography-tandem mass spectrometry (GC-MS/MS). The calibration curves for most pesticides were linear in the range of 15–150 µg/kg, with r2 values higher than 0.9934 and the relative standard deviation for all pesticides was ≤20%. The mean recovery rate of pesticides was 70–120% and limits of detection (LODs) and limits of quantification (LOQs) were in the range of 5–14 µg/kg and 14–40 µg/kg, respectively. The validated procedure was used to monitor pesticide residues in 30 fresh date samples. It could be concluded that the modified QuEChERS extraction method was efficient in analysing pesticide residues in dates palm and none of the samples contained residues above the MRLs.

ABSTRACT PCDD/F and PCB concentrations were analysed in sediments, fish muscles, and livers collected from four lakes in Poland. In general, the fish and sediments had low levels of dioxins and PCBs. The total TEQ in the sediments was 0.12–0.47 pg WHO-TEQ g−1 dry matter (dm), the NDL-PCB content was at 0.05–0.36 ng g−1 dm. The muscles contained PCDD/F/DL-PCBs levels of 0.03–3.19 pg WHO-TEQ g−1 wet weight (ww) while the NDL-PCB content was 0.08–27.30 ng g−1 ww. The livers contained 0.73–8.74 pg WHO-TEQ g−1 ww and the NDL-PCB content was 1.52–88.84 ng g−1 ww. The potential health risk for fish consumers was assessed using the Tolerable Weekly Intake (2 pg WHO-TEQ/kg bw). The consumption of 200 g of fish containing an average PCDD/D/DL-PCB content results in an intake of 43–455% TWI and 14–150% TWI for children and adults, respectively, depending on fish species and sampling point.

ABSTRACT This study aimed to assess the levels of selected pesticides residues in harvested tomatoes and their associated dietary risks to consumers at Makambako Town in Njombe region, Tanzania. Forty-two fresh tomatoes were sampled among tomato farmers during harvesting season and extraction of analytes was done using QuEChERS method and analysed by Gas Chromatography-Mass Spectrometer. Residues of chlorpyrifos, profenofos, gamma cyhalothrin and cypermethrin were alternatingly detected in 78.51% of samples. The average concentrations of residues were 0.014, 0.056, 0.003 and 0.2 mg/kg for chlorpyrifos, profenofos, gamma cyhalothrin and cypermethrin and were all below their respective Codex MRLs. The highest concentration was 0.718 mg/kg for cypermethrin, above the Codex MRL of 0.2 mg/kg. The hazard indexes indicate no potential health hazards to the general population due to the lifetime consumption of fresh tomatoes from the study area. Periodic monitoring of residue levels of pesticides in vegetable fruits, including tomatoes, is recommended.

ABSTRACT A total of 120 spirit drinks and 40 apple juices were collected between 2018 and 2020 in three regions of Turkey and analysed by high-performance liquid chromatography coupled with a photodiode array detector (HPLC-PDA) for the incidence of patulin. The analytical method was successfully validated for both matrices. In 26.7% of apple juice samples, patulin was quantified at levels between 5.8 and 66.4 µg L−1. Only one regulatory level exceedance was identified for apple juice. The mean dietary exposure of the adult population to patulin ranged from 0.083 to 0.091 ng kg−1 bw day−1. With the HPLC-PDA method, patulin was measured in quantifiable concentrations in 11 out of 25 cognac, 5 out of 40 liqueur, and 1 out of 10 whisky samples, up to a level of 42.6 µg/l, whereas all vodka samples were free from patulin. In only one liqueur sample, the presence of patulin could be confirmed with LC-MS/MS, at a level of 8.9 µg L−1.

ABSTRACT To study the contamination levels of perfluoroalkyl acids (PFAAs) in Chinese eggs and the effects of persistent organic pollutant (POP) amendments to the Stockholm Convention blacklist, 3200 eggs from 10 major producing areas were collected from June 2013 to May 2017. Seventeen PFAAs in eggs were analysed. Perfluorooctane sulphonic acid (PFOS), perfluoropentanoic acid (PFPeA) and perfluorooctanoic acid (PFOA) were the main PFAAs in eggs. Perfluoroalkyl carboxylic acids (PFCAs) and short-chain PFAAs levels in eggs decreased after the amendment was implemented in China (p < .05), but no significant difference was observed in PFOS. The average ΣPFAAs of eggs from 10 major producing areas was 0.23 ng/g (

A total of 51 food samples (18 rice, 17 wheat flour, and 16 nuts) were randomly collected from different shops and analysed for the presence of total aflatoxins, ochratoxin A and fumonisins, using a lateral flow competitive immunochromatographic assay method. Mycological contamination (total aerobic and fungi count), colour index (L*a*b*) and moisture content were also evaluated. Sensory characteristics for mycotoxins contaminated and uncontaminated samples of rice and wheat flour were evaluated by 40 panellists. Forty-five per cent of all samples were positive for aflatoxins as the most occurred mycotoxins, with a range of 2-8.1 μg/kg. Fungal counts were not significantly different between contaminated and uncontaminated rice and wheat flour samples. In addition, panellists were able to discriminate between contaminated and uncontaminated rice samples by detection of mouldy flavour, spoilage symptoms, earthy flavour, and the degree of freshness.

The objective of this study was to analyse the content of OHCs and NDL-PCBs in wild boar population living in densely populated flatland region with intensive agricultural production. A total of 82 liver samples were analysed by GC-MS method, revealing the presence of minimum one residue in the liver of the majority of animals (92.7%). Most commonly detected residues included ∑ HCH (64.6%), ∑endrin (56.1%) and ∑dieldrin (32.3%). Mean concentrations were in the range ∑endrin > ∑dieldrin > ∑HCH > ∑NDL-PCB > ∑DDT > ∑CHL > ∑endosulfan > methoxychlor. The dominant compound within the total content of NDL-PCBs was PCB 153 (76%). The assessment of daily intake and determination of Health Index indicated that in 6.1% of the samples the consumption of one single portion of wild boar liver would be harmful to human health due to the presence of ∑endrin or NDL-PCBs.
