Can there be lead or mercury in the fish oil pills that you take for Omega-3s?

If you want to be certain, look for brands which are "molecularly distilled". They should contain no detectable levels of Mercury. Yes. They can very well contain mercury (or lead), and most likely do. It does not matter if they are in detectable amounts, because they persistently increase in your body for a life-time. Both are accumulative heavy-metal toxins, so even trace amounts become large amounts in the body over time. A much wiser choice would be to use flax seed oil instead. The body converts flax seed oil into omega-3s without the risks associated with fish oils. It is best to get cold pressed oil that is protected in individual capsules from light, heat, and air. Exposure to these things makes the oil rancid and damaging to the body.

Does lead float or sink in liquid mercury?
Lead floats in mercury.
Is Mercury heavier than Lead?
Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
What does mercury and lead chloride make?
Both lead and mercury are metals, physically lead is solid at room temperature, however mercury is a liquid, but chemically they are both metals. Mercury is a classified as a transition metal, however technically isn't as it doesn't not have a partially filled d-orbital in either it elemental state or as one of it's common ions. Lead on the other hand belongs to the group known as the poor metals.
If you drop a piece of lead into a pool of mercury will it sink or float?
Lead would float in mercury, as it is slightly less dense. (11.3 g/cc for lead, 13.5 g/cc for mercury)
Why can't you extract lead from lead oxide but you can with mercury and mercury oxide?
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide
What are the two radionuclides which concentrate on seafood?
