Environmentally persistent free radicals (EPFRs) are a new class organic pollutant sharing some of the attributes of persistent organic pollutants (POPs). This opinion/short review aims to describe the properties of EPFRs that merit their recognition as an additional and potentially significant source of POPs. EPFRs are ubiquitous in diverse environments because of multiple factors: (1) organic precursors from anthropogenic, biogenic, and other natural emission sources are abundant; multiple mechanisms in PM and soils form (2) EPFRs; and (3) EPFRs are stable and persist for a long time, thereby, accumulate in the environment and potentially transported long range. The hazards of EPFRs arise from their ability to induce oxidative stress and the formation of hazardous byproducts. EPFRs are ultimately deactivated by reactive processes, yielding molecular recombination byproducts that are structurally similar to those classified as POPs. It is plausible that EPFRs may form POPs in vivo in organisms; therefore, they are potential additional sources of exogenous POPs. Understanding the formation of EPFRs and extensive investigation of the pollutants generated from their recombination will add to the growing body of knowledge on their environmental and health hazards.

Scavenging free radical potency of cordycepin is the major bioactive segment extricated from Cordyceps species. In some new years, Cordyceps has gotten growing thought inferable from its distinctive restorative/pharmacological tests. This assessment reviews continuous explores on the counter oxidant impacts and the associated analyses of Cordyceps species. The results from our review show that Cordyceps of the cordycepin applies protective effects against hostile to oxidant injury for certain, afflictions including constant obstructive pneumonic infection (COPD), hepatitis, asthma, cerebral paralysis, Parkinson’s illness (PD), coronary course sickness (CAD), Alzheimer illness, respiratory failure, malignancy infection, maturing, waterfalls, and mind brokenness. Cordyceps coordinates the NF-κB, RIP2/Caspase-1, Akt/GSK-3β/p70S6K, TGF-β/Smads, and Nrf2/HO-1 hailing pathways among others of cordycepin. A couple of assessments focusing in on Cordyceps auxiliaries were surveyed and found to down metabolic speed of Cordyceps and augmentation its bioavailability. In addition, cordycepin further developed opposition, prevented the duplication of viral RNA, and covered cytokine storms, therefore proposing its capacity to treat COVID-19 and other viral defilements. From the accumulated and assessed information, this article gives the speculative reason to the clinical usages of cordycepin and inspects the way for future assessments focusing in on expanding the restorative use of Cordyceps species. Cordycepin and its analogs show unfathomable potential as the accompanying new class of against oxidant specialists.
