| Abstract |
River Yamuna is under constant menace due to pollution levels beyond limit, ensuing chronic poisoning of aquatic biota. Induction of oxidative stress and cellular deformities is a common effect in fish. The present study aimed in assessing impact of environmental pollutants on gonad (testis) of Clarias gariepinus from Wazirabad barrage (entry site) and Okhla barrage (exit site) of river Yamuna in Delhi segment. Antioxidant enzymes assays viz. Super oxide dismutase (SOD), catalase (CAT) and ferric reducing antioxidant power (FRAP); thiobarbituric acid reactive substance assay (TBARS) for determining level of lipid peroxidation and histology for analysis of degenerative changes were employed as biomarkers. The results depicted signs of environmental contamination, hallmarked by significant increase (p < 0.001) in TBARs level (µmol/g wet tissue); significant decrease (p < 0.001) in SOD, CAT (U/mg protein) and FRAP value (U/mg tissue) in response to greater pollution at Okhla barrage as compared to Wazirabad barrage. Degenerative changes viz. unorganized seminiferous tubules, extensive vacuolization in germ cells, inflammatory lesions, greater vacant spaces and condensation of tubular cells prevailed in 75%, 85%, 80%, 80%, and 65% specimens respectively from Okhla barrage. Hence, the selected biomarkers highlighted the existence of greater prooxidative compounds at the exit site resulting in stressful condition for fish in river basin. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 March 2018.
All research outputs
#21,608,038
of 24,119,703 outputs
Outputs from Bulletin of Environmental Contamination and Toxicology
#3,090
of 4,112 outputs
Outputs of similar age
#296,280
of 334,796 outputs
Outputs of similar age from Bulletin of Environmental Contamination and Toxicology
#47
of 67 outputs
Altmetric has tracked 24,119,703 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,112 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 334,796 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 67 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
