|The liver and kidneys don't store stuff, they filter stuff. While it makes sense to worry about the animals you eat being exposed to drugs and other chemicals, the liver's not more toxic than any other part of the animal. Many chemicals are stored in fat or bone, so if you want to be concerned about a certain part, I'd start there.
That said there is a difference between the livers from calves vs. mature beef, and that's nutritional. Veal liver contains about twice the amount of Vitamin A as beef liver, 3 times the zinc, almost four times the Omega-3 fatty acids, and a little less than twice the O-6's. Beef liver contains two times the selenium as veal liver, though. The other figures are comparable. (Figures from www.nutritiondata.com).
Remember, higher values of whatever things don't necessarily make it better. I'd aim to feed some of both, since you have it available to you.
A little 'net surfing seems to point to veal liver being firmer in texture than the liver from a mature cow, and I guess more mild in flavor.
