Roxarsone is a normal used feed additive in animal breeding. Its ecotoxicological effect has been noticed in recent years. However, very few studies have concerned its effect on the enzymatic activities in earthworms. In present study, we investigated the activities of catalase (CAT), acetylcholine esterase (T-CHE), as well as the content of MDA in earthworms exposed to roxarsone. 5 different concentration groups of roxarsone were designed to simulate the process that roxarsone was discharged into soil with animal manure. CAT, MDA and T-CHE in worms were respectively measured in different time after exposure. The results showed that CAT in worms was activated by roxarsone. This activation was dose-dependent to some extent. The content of MDA was almost unchanged during the treatment either in low or in high dose group. T-CHE could be inhibited by roxarsone. This inhibition was more obvious in the high dose level groups than the low ones. As a conclusion, CAT and T-CHE might be used as biomarker of roxarsone contamination in soils.

“…Such stress could indicate exposure to one or more contaminant classes, including polychlorinated biphenyls , PAHs , pesticides , herbicides , and heavy metals . Catalase activity was elevated by exposure to pyrene at concentrations higher than 160 mg/kg in soil to E. fetida . In the present study, pyrene exposure at 55 mg/kg did not significantly elevate CAT activities through the 28‐d exposure.…”

“…Catalase activity changes were measured as well. Pyrene has a similar fused ring composition to that in C 60 , and it also increases CAT activity in worms . Therefore, pyrene was introduced as a positive control for comparison of chemical uptake and stressor‐induced CAT activity changes.…”

Fullerene (C(60)), with its unique physical properties and nanometer size, has been mass-produced for many applications in recent decades. The increased likelihood of direct release into the environment has raised interest in understanding both the environmental fate and corresponding biological effects of fullerenes to living organisms. Because few studies have emphasized fullerene uptake and resulting biochemical responses by living organisms, a toxicity screening test and a 28-d bioaccumulation test for Lumbriculus variegatus were performed. No mortality was observed in the range of 0.05 mg C(60) /kg dry sediment to 11.33 mg C(60) /kg dry sediment. A biota-sediment accumulation factor of micron-sized fullerene agglomerates (µ-C(60)) was 0.032 ± 0.008 at day 28, which is relatively low compared with pyrene (1.62 ± 0.22). Catalase (CAT) activity, an oxidative stress indicator, was elevated significantly on day 14 for L. variegatus exposed to µ-C(60) (p = 0.034). This peak CAT activity corresponded to the highest body residues observed in the present study, 199 ± 80 µg C(60) /kg dry weight sediment. Additionally, smaller C(60) agglomerate size increased bioaccumulation potential in L. variegatus. The relationship between C(60) body residue and the increased CAT activity followed a linear regression. All results suggest that C(60) has a lower bioaccumulation potential than pyrene but a higher potential to induce oxidative stress in L. variegatus.

“…CAT is known to breakdown hydrogen peroxide which is a free radical, into water and molecular oxygen. GST is known to be a second stage detoxification enzyme which also helps to remove the products of stage one metabolism (Otitoju and Onwurah 2007;Zhang et al 2009). Increase in the GST activity was observed for benzene; however, there was decrease in GST activity when the earthworm was exposed to toluene, ethylbenzene, and xylene.…”

Background: Monocyclic aromatic hydrocarbons are toxic compounds which are major components of petroleum products. This study was aimed at identifying histopathological alterations and changes in antioxidants defense systems in Eudrilus eugeniae (earthworm) that can be used as good battery of biomarkers for early detection of pollution associated with hydrocarbons. The toxicological evaluations of benzene, toluene, xylene, and ethylbenzene (BTEX) were carried out against E. eugeniae. Earthworm samples were collected around oil impacted and control sites. The effect of BTEX was investigated on oxidative stress markers of E. eugeniae. Results: Results showed that xylene (1.2 mg/kg) was the most toxic compound, followed by toluene (1.3 mg/kg), ethylbenzene (1.4 mg/kg), and benzene (1.9 mg/kg). The biochemical responses revealed an increase in malondialdehyde level and decrease in the level of superoxide dismutase, catalase, glutathione, and glutathione-S-transferase in E. eugeniae collected around the oil impacted area of Ijegun. The results from the laboratory studies were confirmed in the field studies. Significant histopathological alterations in the whole organisms were observed in both field and laboratory studies. The pathological findings include cellular and epidermal degeneration, and presence of pigment and inclusion bodies. Conclusion: The results reflect the biological effects of hydrocarbon pollution, thus confirming the relevance of histopathological and antioxidant enzymes as biomarkers for detection of hydrocarbon pollution during environmental monitoring programs.
