“…RI is rated as < 150 low risk; 150–300 moderate risk; 300–600 considerable risk; and >600 very high risk. The ER i of the individual heavy metals are classified as < 40 low risk; 40–80 moderate risk; 80–160 considerable risk; 160–320 high risk; and >320 very high risk [ 15 , [17] , [18] , [19] ].…”

“…Kowalska et al [21] assessed 18 pollution indices and estimated their strength and weaknesses. Diwa [24], Elvira [25], Lawrence et al [26], Barbieri et al [27], Ghrefat et al [28], and Gargouri et al [29] provided additional information on interpreting the environmental impact of pollution indices values. In the Czech Republic, Weissmannová et al [30] chronicled the potential ecological risk and human health risk assessment in soils influenced by coal mining and metal processing.…”

“…If the Eir risk values are: (i) less than 40, which implies low ecological risk, (ii) 40 to 80 implies moderate ecological risk, (iii) 80 to 160 implies appreciable ecological risk, (iv) 160 to 320 implies high ecological risk, and (v) more than 320 implies series ecological risk. If the IR risk values are: (i) less than 150, which implies low ecological risk, (ii) 150 to 300 implies moderate ecological risk, (iii) 300 to 600 implies high ecological risk, and (iv) more than 600 implies series ecological risk [24]. The hazard quotient (HQ ) of a rare earth element is estimated as the rare earth element concentration relative to the rare earth element concentration, where no environmental effect was observed.…”

Rare Earth Elements - Emerging Advances, Technology Utilization, and Resource Procurement

Rare earth elements are critical elements in the modern economy. Mining of rare earth elements has significantly intensified in the last several decades and studies of the environmental impact are in their infancy. In trace amounts, rare earth elements may support plant growth and development. At greater concentrations, rare earth elements are increasingly recognized as having a degree of mammalian toxicity; however, the mammalian toxicity potential may not be as acute as that for some heavy metals. The toxicity of rare earth elements requires detailed research to showcase toxicity thresholds for a wide range of ecosystem health. This study reveals case studies demonstrating that investigators rely on pollution indices, which do indicate that mining and ore processing possess environmental challenges. Further research has been identified to evaluate pollution indices for rare earth elements, especially concentrating on their biological availability.

“…Additionally, G. lemaneiformis serves as an excellent bait for aquatic species such as abalone and is a primary source of edible agar [16,18]. The accumulation of Cu in G. lemaneiformis can be transferred to humans via the food chain, thereby presenting potential health risks [19]. So far, studies have mainly focused on the effects of Cu on growth and the accumulation of Cu in G. lemaneiformis.…”

Heavy metal copper (Cu) will inevitably impact the marine macroalgae Gracilariopsis lemaneiformis (G. lemaneiformis), which is a culture of economic importance along China’s coastline. In this study, the detoxification mechanism of Cu stress on G. lemaneiformis was revealed by assessing physiological indicators in conjunction with transcriptome and metabolome analyses at 1 d after Cu stress. Our findings revealed that 25 μM Cu stimulated ROS synthesis and led to the enzymatic oxidation of arachidonic acid residues. This process subsequently impeded G. lemaneiformis growth by suppressing photosynthesis, nitrogen metabolism, protein synthesis, etc. The entry of Cu ions into the algae was facilitated by ZIPs and IRT transporters, presenting as Cu2+. Furthermore, there was an up-regulation of Cu efflux transporters HMA5 and ABC family transporters to achieve compartmentation to mitigate the toxicity. The results revealed that G. lemaneiformis elevated the antioxidant enzyme superoxide dismutase and ascorbate-glutathione cycle to maintain ROS homeostasis. Additionally, metabolites such as flavonoids, 3-O-methylgallic acid, 3-hydroxy-4-keto-gama-carotene, and eicosapentaenoic acid were up-regulated compared with the control, indicating that they might play roles in response to Cu stress. In summary, this study offers a comprehensive insight into the detoxification mechanisms driving the responses of G. lemaneiformis to Cu exposure.
