Mineral elements are essential micronutrients necessary to constitute human tissue and maintain normal physiological functions. Micronutrient deficiencies are an important issue currently faced in the world. The best strategy to solve this problem is to breed special functional types of rice varieties rich in trace elements (special rice for short). A special type of rice that can produce rich nutrients. In order to explore the nutritional value of giant embryo rice, the contents of 17 mineral elements ((K, Ca, Fe, Se, Zn, Cu, Na, Mn, Mg, Ni, Cr, Co, Pb, As, Cd, Ag, Al)) in 5 kinds of giant embryo rice (white giant embryo, giant japonica-GB-12, giant japonica-GB-11 and giant japonica-GB-5, giant japonica-GB-1) were detected by inductively coupled plasma mass spectrometry. After comparison with ordinary rice, it was found that the content of the same mineral element in different samples has a large variation, suggesting that different rice varieties have different absorption, transformation and storage efficiency of the same element; different giant embryo brown rice in some mineral elements (such as Cr, Ni, Cu and Zn) are extremely low in content and almost undetectable. Meanwhile, the brown rice of giant embryo rice has a more powerful enrichment effect on some mineral elements, which means that embryo rice has a unique advantage in cultivating new rice varieties with special functions rich in minerals.

The feasibility of combining elemental fingerprints and chemical pattern recognition methods for authentication of the geographical origins of a Chinese herb, Gastrodia elata BI. (GE), was studied in this paper. A total of 210 GE samples were collected from 7 different producing areas. The levels of 15 mineral elements in GE, including Zn, Cd, Co, Cr, Cu, Ca, Mg, Mn, Mo, Ni, Pb, Sr, Fe, Na, and K, were determined using inductively coupled plasma mass spectrometry (ICP-MS). Using the autoscaled data of elemental fingerprints and partial least-squares discriminant analysis (PLSDA), two chemometrics strategies for multiclass classifications, One-Versus-Rest (OVR) and One-Versus-One (OVO), were studied and compared in discrimination of GE geographical origins. As a result, OVR-PLSDA and OVO-PLSDA could achieve the classification accuracy of 0.672 and 0.925, respectively. The results indicate that mineral elemental fingerprints coupled with chemometrics can provide a useful alternative method for simultaneous discrimination of multiple GE geographical origins.

Abstract An analytical method based on inductively coupled plasma/mass spectrometry (ICP/MS) was developed for the determination of 28 mineral elements (Cr, Mn, Co, Ni, Cu, Zn, Ga, Sr, Cd, Ag, Ba, Pb, Bi Y, La, Ce, Nd, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) in Indian opium samples. The detection limits were found to be in the range of 0.0008–0.45 ng/mL. The recoveries of spiked samples for each element were found to be in the range of 83–106%, with a precision of less than 9%. A total of 124 opium samples from India were analyzed for the distribution pattern of the 28 mineral elements. Quantitative elemental data were subjected to chemometric analysis in order to determine an optimal classifier to evaluate the source of Indian opium. The study indicated that mineral elements might not be the suitable discriminators for the discrimination of licit opium-growing divisions of India. However, the methodology developed and the analytical data on elemental profile may find important forensic application in discriminating Indian opium with that of licit and illicit opium originating from different geographical regions of world.

Mineral Concentrations

Two-thirds of the world’s population are at risk of deficiency in one or more essential mineral elements. The high concentrations of essential mineral elements in pulse seeds are fundamentally important to human and animal nutrition. In this study, seeds of 25 genotypes of faba bean (12 low-tannin and 13 normal-tannin genotypes) were evaluated for mineral nutrients and protein content in three locations in Western Canada during 2016–2017. Seed mineral concentrations were examined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and the protein content was determined by Near-Infrared (NIR) spectroscopy. Location and year (site-year) effects were significant for all studied minerals, with less effect for calcium (Ca) and protein content. Genotype by environment interactions were found to be small for magnesium (Mg), cobalt (Co), Ca, zinc (Zn), and protein content. Higher seed concentrations of Ca, manganese (Mn), Mg, and cadmium (Cd) were observed for low-tannin genotypes compared to tannin-containing genotypes. The protein content was 1.9% higher in low-tannin compared to tannin-containing genotypes. The high estimated heritability for concentrations of seed Mg, Ca, Mn, potassium (K), sulphur (S), and protein content in this species suggests that genetic improvement is possible for mineral elements.

Neoplasms involve abnormal tissue growths developing in an uncoordinated, persistent manner, faster than adjacent normal tissues. Several researchers have studied the possible implications of heavy metals and mineral levels on human mammary neoplasms using hair analysis. The study’s objective was to assess the levels of heavy metals and other mineral elements in dogs suffering from mammary neoplasms. Hair samples were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). All analyzed elements registered higher levels in clinically healthy dogs. The interaction between health status and keeping conditions significantly influenced the levels of Al, Ca, Fe, Mg, Ni, Co, Pb, and V. Concurrently, dogs with mammary neoplasms living outdoors registered the highest levels for most minerals, compared to dogs with mammary neoplasms living indoors, suggesting a possible implication of pollution.
