You pee and poop most of it out. If it is metal, you poop all of it out.
Lead is considered unsafe in drinking water at levels of 15 ppb (parts per billion), toxicity in blood starts above 0.35 mg/L (depending on what you want to consider toxic effects and the age of the person being measured,). In adults blood lead levels above 0.7 mg/L can cause acute toxicity and the potential effects include encephalopathy, coma, and death. An adult has about 5L of blood, if we call it 6L for a large adult and go for a the typical range were the worst symptoms start of 0.8 mg/L, that is 0.074 grains of lead in the blood is enough to potential kill a large adult. Consumed lead metal is bioavailable in humans, though surface area will play more into this than the mass ingested.
Soluble tungsten (such as WO4) is likely safe at levels below 2.28 mg/L in drinking water, soluble tungsten can cause nephrotoxicity at exposure levels of 125 mg/kg/d (a 220 lb man would have to consume 4.4 ounces of soluble tungsten per day). However, non-soluble tungsten (tungsten metal) is not bioavailable and not toxic based on current evidence as it is eliminated in the stool. Prolonged exposure to soluble tungsten may increase risk of heart attacks and strokes, but beyond potential nephrotoxicity there are not acute syndromes associated with it. No toxic effects have been observed from tungsten metal and it does not appear to be bioavailable.
The two are not comparable beyond the fact that they are both metals.
