“…Of the total number of naturally occurring chemical elements, 26 are considered essential to animal or human life, and most occur as trace elements. Along with diet intake [12,14,15], environmental interaction can promote absorption of trace elements, which may become toxic above certain concentration thresholds [14,16].…”

Polycystic ovary syndrome (PCOS) is a prevalent condition in women of reproductive age. PCOS is characterized by androgen excess and chronic anovulation and associated with low-grade inflammation and metabolic comorbidities. Some trace elements have been linked to pathophysiological mechanisms of oxidative stress and inflammation in different disorders. Therefore, we conducted a systematic review and meta-analysis of the available evidence regarding trace element concentrations in PCOS. We reviewed MEDLINE and EMBASE in search of case-control, cross-sectional, and cohort studies published until September 2015. Of 183 studies identified, six were selected for systematic review. All used the Rotterdam criteria for the diagnosis of PCOS. Two studies evaluating chromium and one assessing cobalt levels did not observe differences between PCOS and controls. Another study recorded similar nickel and vanadium levels between the groups, but lower selenium concentrations in women with PCOS compared to controls. Four studies were included in the random effects model meta-analysis, for a total of 264 PCOS and 151 control women. Copper levels were found to be higher in women with PCOS than in controls [mean difference 0.12 ppm (95 % CI 0.07; 0.17 ppm); I 2 = 0 %]. Manganese [mean difference 0.04 ppm (95 % CI −0.05; 0.13 ppm); I 2 = 94.4 %] and zinc concentrations [mean difference 0.02 ppm (95 % CI −0.12; 0.16 ppm); I 2 = 92.4 %] were similar between the groups. The present results suggest a relationship between increased copper concentration and PCOS. This systematic review and meta-analysis is registered in PROSPERO under number CRD42016034036.

“…Cd can be absorbed from the soil by crops and aquatic organisms. Long‐term exposure to Cd causes serious harmful effects such as lung disease and calcium metabolism disorder in humans; moreover, Cd is a potential carcinogen . Recently, increasing Cd contamination in food and drinking water has been one of the major concerns of the World Health Organization and the International Agency for Research on Cancer .…”

An exponential increase of heavy metal toxicant in the human body is a growing health-related problem. In the present study, Pediococcus pentosaceus FB145 and FB181 strains were isolated from fermented seafood and served as highly Cd-resistant strains. The unchanged structural cells of P. pentosaceus strains after treatment with Cd cations were investigated using a scanning electron microscope energy dispersive X-ray analysis. Furthermore, both P. pentosaceus strains showed strong human gastrointestinal tract resistance properties. The Cd biosorption results fit the pseudo-second-order kinetics with capacities for P. pentosaceus FB145 and FB181 for Cd were 52.8 and 50.3 mg/g, respectively, whereas the maximum biosorption capacities were 52.65 and 50.35 mg/g, respectively. The equilibrium data were well fitted to the Freundlich isotherm model. The binding of Cd to bacterial cells may be caused by the presence of different functional groups such as carboxyl, amide, and phosphate on cell surface, which was confirmed by the Fourier transform infrared-attenuated total reflectance spectra. Moreover, these strains decreased the Cd bioaccessibility by 44.7-46.8% in the in vitro digestion model. These findings indicate that P. pentosaceus FB145 and FB181 are novel potent biosorbent for preventing cadmium toxicity and reducing its absorption into the human body.

“…Arsenic (As) is one of the toxic metalloids and can cause toxicological effects on all living organisms (Rosas-Castor, Guzmán-Mar, Hernández-Ramírez, Garza-González, & Hinojosa-Reyes, 2014;Tripathi, Singh, Mishra, Tripathi, & Nautiyal, 2015;Vázquez et al, 2015). Soil contamination with heavy metal(oid)s due to anthropogenic activities, such as industrial activities, agrochemical application, and mining (Rehman et al, 2016), results in land degradation (Khaledian, Kiani, Ebrahimi, Brevik, & Aitkenhead-Peterson, 2016;Roy & McDonald, 2015).…”

Arsenic (As), being a toxic metalloid, is widely found in degraded land and severely affects the health of plants and human beings. Pot experiments were conducted to assess the effects of As on plant nutritional values (macronutrients and micronutrients). Three vegetables (potato, tomato, and lettuce), on the basis of taxonomic differences, were selected and grown on As degraded soils at four different concentrations (0, 0.5, 1.0, and 1.5 mg kg−1); additionally, the effect of Cd and Pb on the As uptake by plants was studied. The edible parts were analysed for As, Cd, Pb, and essential macronutrients (vitamin C, protein, N, P, and K) and micronutrients (Ca, Mg, Fe, and Mn). The As concentrations in lettuce, potato, and tomato were 0.76, 0.63, 0.57 mg kg−1, respectively, grown in soil with no contamination, whereas in contaminated vegetables, the concentration varied significantly depending upon the level of contamination. As interaction with Cd and Pb showed negative correlation, generally, with increasing of As concentration, the Cd and Pb concentrations decreased; however, this trend was not consistent for all treatments and selected plant species. The nutrient concentrations significantly (p < .001) varied in contaminated vegetables compared with the control. The amendments of As significantly (p < .01) increased the concentrations of Ca, N, and protein, whereas P and K concentrations were decreased. The correlation between As with Mn, Mg, and vitamin C depended upon the types of vegetables and the contamination levels. Mn contribution to the Recommended Dietary Allowance was significantly (p < .01) lower for contaminated vegetables, whereas less significant (p = .05) for Fe, Mg, P, and K and non‐significant for Ca, N, and protein for different age groups. It was observed that As degraded soil affected the quality and nutritional balance in vegetables and potentially the nutrient status of consumers. The nutrients degradation in contaminated vegetables was obviously higher because As concentration reduce soil to plant transfer of essential elements by forming metal‐oxide complexes.
