Antioxidant responses in Carassius auratus and Lolium perenne exposed to the laboratory pollution

• Antioxidant responses in fish and plants exposed to the air pollution in four different laboratories were evaluated.
• The measured parameters (SOD, CAT, GSH, and MDA) were significantly altered after chronic exposure.
• Toxicity order was proposed according to the antioxidant responses.

Experiments conducted in the laboratories can produce numerous wastes, which could potentially affect the health of the researchers. In this study, the antioxidant responses in liver of Carassiua auratus and leaf of Lolium perenne were investigated after chronic exposure to the air pollution in four different laboratories. The obtained data showed that oxidative stress was induced in some laboratories, as indicated by some significantly altered biochemical parameters. Additionally, the toxicity order was tentatively proposed based on these responses. The results indicated that these biochemical indices can be used as the oxidative stress biomarkers to assess the effect of environmental pollution on the living organisms, and this study can facilitate the understanding of the risk assessment of laboratory pollution.
