TLDR
Prolonged exposure to chlorpyrifos enhanced ROS formation, finally resulted in oxidative damage to cell and inhibited antioxidant capacities in the fish tissues.Abstract:
Study on the chronic effects of an organophosphate chlorpyrifos inducing oxidative stress in freshwater culturable carp Ctenopharyngodon idellus has been made on exposure to sub lethal concentration micro g L and micro g L of the pesticide for and days Antioxidants viz catalase CAT superoxide dismutase SOD reduced glutathione GSH glutathione s transferase GST and lipid peroxidation LPO in the liver kidney and gills of the fish were analyzed Studies revealed that the enhanced productions of reactive oxygen species ROS lead to oxidative damage to lipids amp proteins and inhibit antioxidant defence system of fish The activity of LPO has followed an increasing trend and a decline in the activity of CAT SOD and GSH at both the concentrations throughout the experiment However no definite trend in the activity of GST has been observed Prolonged exposure to chlorpyrifos enhanced ROS formation finally resulted in oxidative damage to cell and inhibited antioxidant capacities in the fish tissuesread more

Relationships between tissue concentrations of polycyclic aromatic hydrocarbons and antioxidative responses of marine mussels, Perna viridis
TL;DR: In this paper, local mussels, Perna viridis, were transplanted from a relatively clean site to various polluted sites in Hong Kong, and different antioxidant parameters including glutathione S transferase (GST), superoxide dismutase (SOD), catalase (CAT), glutathion peroxidase (GPx), glutthione reductase (GR), NADPH DT-diaphorase (DT-d), and lipid peroxidation were quantified, and tissue concentrations of benzo[a]pyrene (B

TL;DR: It is revealed that TCEP at tested concentrations causes adverse effects on fish and the studied biomarkers could be used for monitoring the ecotoxicity of organophosphate esters (OPEs).

Heavy metals, parasitologic and oxidative stress biomarker investigations in Heterotis niloticus from Lekki Lagoon, Lagos, Nigeria.
TL;DR: Combined effects of parasitism and heavy metal pollution in fish elicits antioxidant response in fish, and parasitic infection in fish is positively skewed towards male fish.

Microsomal lipid peroxidation.
John A. Buege,Steven D. Aust +1 more
TL;DR: This chapter discusses microsomal lipid peroxidation, a complex process known to occur in both plants and animals that involves the formation and propagation of lipid radicals, the uptake of oxygen, a rearrangement of the double bonds in unsaturated lipids, and the eventual destruction of membrane lipids.

Standard methods for the examination of water and waste water.
TL;DR: Alkalinity measurements are used in the interpretation and control of water and wastewater treatment processes and can be interpreted in terms of specific substances only when the chemical composition of the sample is known.

Fish bioaccumulation and biomarkers in environmental risk assessment: a review
TL;DR: There is little doubt that measurements of bioaccumulation and biomarker responses in fish from contaminated sites offer great promises for providing information that can contribute to environmental monitoring programs designed for various aspects of ERA.
