Dose and duration of Cd administered	Tissue/Animal	Response to Cd exposure	Reference
0.1, 0.5, 1.0 and 2.0 mg/L for 30 days	Male Swiss albino mice	Dose-dependent increase of ROS in blood stream Reduced CAT, SOD and GSH-Px enzyme activity in liver, kidney, spleen, testis and brain	[10]
15 mg/kg b.w./day single dose 15 mg/kg b.w./day for 60 days	Male Wistar albino rats	Significant increase in CAT and MDA levels in erythrocytes compared to control group Significant increase in CAT, GSH-Px, SOD and MDA in erythrocytes compared to control group	[11]
30 mg/kg b.w. for 21 days	Male Wistar rats	Significant increase in MDA levels in blood stream Significant reduction in GSH, SOD and CAT levels in blood stream	[37]
15 and 100 ppm for 60 days	Male Wistar rats	Increased CAT and SOD levels in heart tissue at 15 ppm dose Significant increase in CAT levels in heart tissue at 100 ppm	[38]
40 mg/L for 6 weeks	Male albino rats	Significant decreases of CAT, SOD and reduced GSH in plasma significantly reducing the total antioxidant capacity Significant increase in MDA levels in plasma	[39]
5 mg/kg b.w. for 30 days	Adult male albino Wistar mice	Liver CAT, SOD, GRx and GST were significantly reduced while liver MDA was significantly increased	[40]
50 mg/L for 12 weeks	Male Wistar rats	Decreased activity of SOD and GPx while reducing levels of GSH and total antioxidant capacity in liver tissues	[41]
10 and 50 ppm for 30 days	Female Sprague-Dawley rats	Elevated blood plasma MT levels till 7 days after exposure and reduced blood plasma MT levels in the following 2 weeks.	[42]
