“…According to the two determinative factors of the THM concentration and body weight, estimated maximum intake (EMI) and the estimated daily intake (EDI) were calculated to assess aHI and HQ. The relevant equations were as follows:

EMI = \frac{FIR \times C \max}{normalBW}

EDI = \frac{EF \times ED \times FIR \times C avg}{BW \times T a}

aHI = \frac{normalEMI}{normalRfD} \times 100 %

HQ = \frac{normalEDI}{normalADI} \times 100 %

where FIR represents the per capita ingestion rate (0.05 kg person −1 d −1 ); C max is the maximum concentration of THMs (in mg kg −1 ); EF is the frequency of exposure (365 d yr −1 ); ED, the exposure period (70 years); C avg is the mean concentration of THMs (in mg kg −1 ); BW, mean body weight for adults (60 kg) and children (25 kg); T a is the mean exposure time (365 d yr −1 × ED); the daily exposure reference dose (RfD) for Pb, As, Cr, Cd and Hg are 0.0036, 0.003, 0.003, 0.001 and 0.0001 mg kg −1 d −1 , respectively; the acceptable daily intake (ADI) for Pb, As, Cr, Cd and Hg are 214, 128, 60, 43 and 200 µg d −1 by the World Health Organization (WHO), respectively; the mean body weight for ADI calculation (50 kg).…”

BACKGROUND Toxic heavy metals (THMs) cause severe environmental hazards and threaten human health through various consumption of food stuff. However, little is known of THMs in chestnuts. In this study, the risk assessment and prediction of THMs [lead (Pb), arsenic (As), chromium (Cr), cadmium (Cd) and mercury (Hg)] in chestnuts and growth soils from China were investigated. RESULTS The main detected THMs in chestnuts and growth soils were As and Cd. The total pollution levels of the five THMs (Nemerow pollution indexes, NPIs) were 0.062 and 1.06, respectively. The dietary risks for children were higher than those of adults, especially short‐term non‐carcinogenic risk. The main combined risks from the relationships between THMs were Pb‐Cr (r = 0.85, P < 0.01) in chestnuts and Pb‐As (r = 0.59, P < 0.01) in growth soils. The risk source was found to be the uptake effect of THMs from soil to chestnut, with the highest bioaccumulation factors (BCFs) of Cd (0.254). Several comprehensive risk models were established with the highest coefficient of determination (R2) of 0.79. In addition, the main contribution rates of different soil parameters to comprehensive risk of THMs uptake were 49.8% (Cd), 23.4% (pH), 13.8% (Cr) and 13.0% (organic carbon). CONCLUSION The total pollution levels of THMs fell outside of the safety domain in growth soils. Furthermore, more attention needs to be paid to Cd pollution owing to its low environment background value and high accumulation ability. Three main soil parameters (Cr content, pH, organic carbon) played important roles in the formations and accumulations of THMs in chestnuts. © 2019 Society of Chemical Industry

“…Endogenous factors such as body size, growth, fitness, reproductive condition and genotypes [21], the differences in biokinetic uptake, depuration rate, and other physiological processes could contribute to the variations in the heavy metal concentration in tissues [22]. Meanwhile, the exogenous factors could be salinity, metal bioavailability [23], alkalinity, and others [19]. Pearson correlation between metals in muscle tissues in P. reticulata showed in Table 1 and a significantly positive linear correlation (p < 0.05) were observed between concentrations of some metals (As-Co, Cr-Fe, Hg-Ni, Co-Ni, Mn-Ni, Cd-Se, Mo-Tl) and significantly negative linear correlation (p < 0.05) (Cu-Tl and Pb-V).…”

The concentration of nineteen metals (Hg, As, Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Mo, Ni, Pb, Se, Sr, Ti, Tl, V, and Zn) were determined in muscle tissues and digestive contents of Periglypta reticulata (Kerang Geton), collected from Lancang Island part of Seribu Islands, Jakarta. An interaction between toxic and essential metal in a clam is also studied. The results showed high concentrations of As (4.56), V (1.20), and Zn (4.91) mg/kg wet weight in muscle tissues and As (7.16), Ti (2.53), and Zn (8.68) mg/kg wet weight in digestive contents. Average concentrations of metals in muscle tissues and digestive contents were below regulation limit from permissible standard National Agency of Drug and Food Control except for Arsenic (As). The average concentration of metals in muscle tissues was significantly (P < 0.05) lower than in digestive contents except As, Co, Cr, Mg, and Tl, respectively. Toxic metals (Pb, Hg, Cd, and As) showed a strong correlation with several essential metals so that these metals can be a threat to the main function of a particular metal. The present study showed digestive contents could accumulate in higher metals; therefore, we suggested removing it before consuming this clam.

“…Transduction of heavy metal stress signaling is started by ion channels/receptors through awareness of stress signals and also through non-protein messengers like hydrogen ions, calcium and cyclic nucleotides as given in ( Figure 1 ). Several studies reported the importance of these signaling molecules and responsive genes in plants against the stress induced by HMs [ 56 , 57 , 58 , 59 , 60 ].…”

Unexpected biomagnifications and bioaccumulation of heavy metals (HMs) in the surrounding environment has become a predicament for all living organisms together with plants. Excessive release of HMs from industrial discharge and other anthropogenic activities has threatened sustainable agricultural practices and limited the overall profitable yield of different plants species. Heavy metals at toxic levels interact with cellular molecules, leading towards the unnecessary generation of reactive oxygen species (ROS), restricting productivity and growth of the plants. The application of various osmoprotectants is a renowned approach to mitigate the harmful effects of HMs on plants. In this review, the effective role of glycine betaine (GB) in alleviation of HM stress is summarized. Glycine betaine is very important osmoregulator, and its level varies considerably among different plants. Application of GB on plants under HMs stress successfully improves growth, photosynthesis, antioxidant enzymes activities, nutrients uptake, and minimizes excessive heavy metal uptake and oxidative stress. Moreover, GB activates the adjustment of glutathione reductase (GR), ascorbic acid (AsA) and glutathione (GSH) contents in plants under HM stress. Excessive accumulation of GB through the utilization of a genetic engineering approach can successfully enhance tolerance against stress, which is considered an important feature that needs to be investigated in depth.
