Capsicum annuum L. belonging to the family Solanaceae is a popular spice in Thailand. The mature fruits (long red pepper) are composed of carotenoid, capsaicinoid and ascorbic acid exhibiting physiological and pharmacological properties. Because of environmental pollution, these fruits might be contaminated with toxic heavy metals. Therefore, the objective of this study was to determine the concentrations of eleven heavy metals in long red pepper using nitric acid digestion followed by ICP-MS analysis. Thirteen samples of fresh fruits were collected from nine provinces located in the west of Thailand. The concentrations of toxic heavy metals including arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) in all samples were lower than the permissible limits (4, 0.3, 0.02, and 10 mg/kg, respectively) while the concentrations of essential elements including copper (Cu) and zinc (Zn) were less than the permissible limits (20 and 100 mg/kg, respectively). The highest concentrations of aluminium (Al), chromium (Cr), iron (Fe), manganese (Mn), and nickel (Ni) found were 36.813, 0.345, 44.464, 32.172, and 1.623 mg/kg, respectively. The method adopted in this study could be valuable in quality control of edible spices for Thai people.

Moringa oleifera Lam. leaf capsules collected from markets in Nakhon Pathom, Thailand were determined for 11 heavy metals (Al, As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn) by inductively coupled plasma-mass spectrometry (ICP-MS) using acid digestion for sample preparation. The concentrations of Al, As, Cr, Cu and Hg in all samples of M. oleifera capsules were found within permissible limits and normal ranges. In contrast, Fe, and Zn concentrations in all samples were higher than permissible limits. Furthermore, the concentrations of Cd, Mn, Ni, and Pb in some samples were higher than permissible limits and normal ranges. The presence of elevated levels of Cd, Fe, Mn, Ni, Pb, and Zn in M. oleifera capsules is a serious matter of concern. Therefore, it is important that doctors and consumers are aware of this matter especially during the routine taking of M. oleifera capsules.

Abstract Medicinal plants possess several metals obtained naturally or through pollution. The study evaluates the genotoxic potentials and the presence of essential elements and toxic heavy metals in Sesbania sesban var. bicolor (leaves), Cyperus compressus (roots) and Asparagus racemosus (roots), which are used as anthelmintics in the traditional medicine of the Santhals in India. Genotoxicity study was performed as per Organization for Economic Co-operation and Development (OECD) guidelines in rats. Element contents were evaluated using inductively coupled plasma-optical emission spectrometry (ICP-OES). Administration of S. sesban var. bicolor (400 mg/kg), C. compressus (700 mg/kg) and A. racemosus (500 mg/kg) did not cause any abnormalities in the chromosomes. Elemental analysis revealed the presence of lead (5.00 ± 0.05, 4.98 ± 0.01, 4.99 ± 0.07 ppm), cadmium (4.99 ± 0.04, 4.90 ± 0.03, 5.00 ± 0.08 ppm) and arsenic (0.98 ± 0.03, 0.41 ± 0.05, 0.92 ± 0.03 ppm), respectively. Although genotoxic potentials were lacking, the presence of toxic heavy metals in them is a cause of concern.

In this study, the level of arsenic (As), lead (Pb) and cadmium (Cd) and also essential elements in beer samples consumed in Turkey were investigated using the inductively coupled plasma mass spectrometry (ICP-MS) method. The heavy metal-induced non-carcinogenic and carcinogenic risks were calculated. For essential elements, the calculated estimated daily intake of iron (Fe), copper (Cu), selenium (Se) and cobalt (Co) from beer consumption were compared with their toxicity reference values. Tukey post-hoc test showed that As was found at a significantly higher level when compared to Pb. Also, a significant correlation was found between As level and alcohol by volume percent. All samples had a hazard quotient and hazard index <1, indicating no non-carcinogenic risk from exposure to single or multiple heavy metals. Some samples exceeded the threshold limit of acceptable cancer risk for As in the high beer consumer group. This assessment showed that in addition to health implications based on the alcohol content of beer, there might be a carcinogenic risk associated with the heavy metals content of these beverages.

In terms of nutrition, dates are an important commodity because they are a source of carbohydrates and minerals. Saudi Arabia is the second largest producer of dates worldwide. Khalas is the tenth most popular date type in the Kingdom of Saudi Arabia (KSA), but only limited information related to the levels of essential nutrients in Khalas dates is available. The concentrations of Mn, Cu, Zn, and Se were determined using inductively coupled plasma-mass spectrometry (ICP-MS). The average concentrations in wet weight were as follows (mg/kg): Mn (2.90 ± 0.54), Cu (1.78 ± 0.64), Zn (1.72 ± 0.42), and Se (0.10 ± 0.06). The calculated intakes (μg/kg bw day) per 100 g dates for each element were as follows: Mn (4.14), Cu (2.54), Zn (2.46), and Se (0.14), which represent 0.14%, 0.51%, 0.25%, and 0.2%, respectively, of the provisional maximum tolerable daily intake (PMTDI) recommended by the EFSA/WHO. It was found that levels of the analysed essential elements in up to 100 g of Khalas dates do not exceed the level set by the EFSA/WHO.
