Title:  Biochemistry, cytogenetics and bioaccumulation in silver catfish (Rhamdia quelen) exposed to different thorium concentrations
 
Authors:  Correa LM, Kochann D, Becker AG, Pavanato MA, Llesuy SF, Loro VL, Raabe A, Mesko MF, Flores EMM, Dressler VL, Baldisserotto B
 
Drug:  Thorium
 
Fish species:  Catfish, South American (silver)
 
Date:  2008
 
Sample:  skin
 
Ave Weight (gm):  6
 
Ave Water temp (°C):  22
 
Water:  Freshwater
 
Dosage:  0.6087 mg/L 15d
 
Route:  BATH
 
Comments:  Fish were placed in recipients with water and ice for 5 min for anesthetization. Thorium (Th) concentrations in the water corresponded to a progressive increase of Th levels in the gills, liver, skin, and kidney, however, this relationship was not found in bile, brain, or muscle. Fish exposed to the highest levels of waterborn Th levels showed the highest levels of Th accumulation (287 ug/g) in the skin.
