Heavy Metal Chronicles: Assessing Antioxidant Enzyme Activity and Oxidative Stress in Perionyx Excavates Exposed to Contamination | Chapter 9 | Cutting Edge Research in Biology Vol. 9

 This study proposed to investigate the poisonous effects of weighty metals, specifically mercuric chloride, policeman sulfate, zinc sulfate, and their combination, on the endeavor of antioxidant enzymes in the earthworm species Perionyx excavates. The experiment complicated exposing the worms to variable concentrations of the heavy metals. The concentrations of mercuric chloride categorized from 25 to 30 mg/kg of dry soil, copper sulfate concentrations categorized from 60 to 150 mg/kg of dry soil, and zinc sulfate concentrations categorized from 140 to 350 mg/kg of dry soil. The exposure event was set at 5 days. Throughout the experiment, the activities of three antioxidant enzymes, that is to say Superoxide Dismutase (SOD), Catalase (CAT), and Glutathione-S-transferase (GST), were monitored. The results illustrated a dose-weak and time-contingent increase in the activities of these enzymes. Among the difficult metals tested, mercuric chloride shown the highest toxicity at its maximum aggregation. Furthermore, the combination of policeman sulfate and zinc sulfate at their topmost concentrations also presented significant toxicity. In conclusion, this study focal points the detrimental belongings of heavy metal uncovering on the antioxidant enzyme activity in Perionyx excavates. The verdicts emphasize the potential environmental risks associated with sounds that are pleasant contamination and the significance of understanding the biochemical responses of creatures to such contaminants. Further research is warranted to exemplify the underlying mechanisms and enduring consequences of form of rock and roll toxicity in earthworms.

Study on Degradation of Leaf Litter of Five Tree Species by Perionyx excavatus with Relation to Their Nutrient and Anti-nutrient Content | Chapter 1 | Research Aspects in Agriculture and Veterinary Science Vol. 2

 The ecological acceptability of various leaf litter forms in promoting biological diversity and soil micronutrient status must be studied before selecting plant species for afforestration procedures. The current study looked at the colonisation of an epigeic earthworm, Perionyx excavatus, in the decomposing leaf litter of five locally important tree species, including Cashew, Shal, Mango, Acacia, and Eucalyptus, over a 90-day period. In laboratory microcosms, the primary nutrient and anti-nutrient chemical parameters of the leaf litters were compared, and the rates of degradation of the selected nutrient and anti-nutrient parameters were investigated. P. excavatus demonstrated the most colonisation for Cashew, followed by Shal, with both tree species having considerably higher rates of degradation of the investigated nutritional parameters and reduced anti-nutrient content. Eucalyptus, which had the highest polyphenol and tannin content and significantly lower rates of degradation of all the investigated nutritional parameters and thus their use in microcosms with P. excavatus, had the least colonisation by P. excavatus. The results showed that decreased tannin and polyphenol content in Cashew and Shal leaf litters can be linked to the palatability of these leaf litters, resulting in maximum colonisation by P. excavatus. As a result, Cashew and Shal are appropriate tree species for afforestation strategies that improve nutrient recycling and soil conservation.
