Abstract The present study was carried out to study modulator effect of caffeine (1,3,7-Trimethylxanthine) on Lead induced alterations on freshwater mussels, Lamellidens corrianus. The Freshwater mussels, L. corrianus were exposed to chronic LC50/10 dose of Lead nitrate ( 6.321 ppm) for 12 days.After 12days Lead exposed mussels were allowed to cure naturally and with caffeine . The digestive glands and gills from different groups were removed and dried in the oven. The dry powders were digested in nitric acid and perchloric acid in 4:1 ratio at hot temperature till dryness. The digest was dissolved in double glass distilled water and the lead and cadmium contents were estimated by the Atomic Absorption Spectrophotometer. After 12 days of exposure, the amounts of bioaccumulated lead in the digestive glands and gills were 750 to 1.230 and 489 to 894 gm/Kg respectively, which decreased within the range of 568 to 932 and 415 to 675 gm/Kg under the influence of caffeine. During the recovery after 12 days, the bioaccumulated lead was reduced to 1.057 to 835 and 728 to 518 gm/Kg of normal water while in caffeine exposed mussels it was reduced to 950 to 680 and 635 to 494 gm/Kg in digestive glands and gills respectively. Decrease in the lead contents in caffeine exposed mussels indicates the role of caffeine in lead excretion. Therefore, the caffeine (1, 3, 7-Trimethylxanthine) as a modulator of lead bioaccumulation in the experimental mussels model, L. Corrianus.
