“…Plants subjected to heavy metals or organic pollutants may generate reactive oxygen species such as hydrogen peroxide (H 2 O 2 ), superoxide anion radical (⋅ O 2 − ), and hydroxyl radical (⋅OH) ( Guo et al, 2022 ; Gao et al., 2022 ). To counteract the cellular damage caused by reactive oxygen species and maintain the homeostatic balance of plant cells, the defense system of the plant organism can eliminate reactive oxygen species through the production of enzymes (including CAT, POD, and SOD, etc. )…”

Background Tungsten (W) is an emerging heavy metal pollutant, yet research remains scarce on the biomonitor and sensitive biomarkers for W contamination. Methods In this study, celery and pepper were chosen as study subjects and subjected to exposure cultivation in solutions with five different levels of W. The physiological and biochemical toxicities of W on these two plants were systematically analyzed. The feasibility of utilizing celery and pepper as biomonitor organisms for W contamination was explored and indicative biomarkers were screened. Results The results indicated that W could inhibit plants’ root length, shoot height, and fresh weight while concurrently promoting membrane lipid peroxidation. Additionally, W enhanced the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and total antioxidant capacity (TAOC) to counteract oxidative damage. From a physiological perspective, pepper exhibited potential as a biomonitor for W contamination. Biochemical indicators suggested that SOD could serve as a sensitive biomarker for W in celery, while TAOC and POD were more suitable for the roots and leaves of pepper. In conclusion, our study investigated the toxic effects of W on celery and pepper, contributing to the understanding of W’s environmental toxicity. Furthermore, it provided insights for selecting biomonitor organisms and sensitive biomarkers for W contamination.

Plastic waste is ubiquitously present across the world, and its nano/sub‐micron analogues (plastic nanoparticles, PNPs), raise severe environmental concerns affecting organisms’ health. Considering the direct and indirect toxic implications of PNPs, their biological impacts are actively being studied; lately, with special emphasis on cellular and molecular mechanistic intricacies. Combinatorial OMICS studies identified proteins as major regulators of PNP mediated cellular toxicity via activation of oxidative enzymes and generation of ROS. Alteration of protein function by PNPs results in DNA damage, organellar dysfunction, and autophagy, thus resulting in inflammation/cell death. The molecular mechanistic basis of these cellular toxic endeavors is fine‐tuned at the level of structural alterations in proteins of physiological relevance. Detailed biophysical studies on such protein‐PNP interactions evidenced prominent modifications in their structural architecture and conformational energy landscape. Another essential aspect of the protein‐PNP interactions includes bioenzymatic plastic degradation perspective, as the interactive units of plastics are essentially nano‐sized. Combining all these attributes of protein‐PNP interactions, the current review comprehensively documented the contemporary understanding of the concerned interactions in the light of cellular, molecular, kinetic/thermodynamic details. Additionally, the applicatory, economical facet of these interactions, PNP biogeochemical cycle and enzymatic advances pertaining to plastic degradation has also been discussed.
