Biological weapons involve living things, such as germs. Mercury is a chemical, not a biological. Bio weapons might include the diseases of anthrax, plague, typhus, Ebola, etc.
The advantage is that chemical weapons doesn't destroy buidings. Also these weapons can be used by poor nations without nuclear weapons.The disadvantage is that chemical weapons contribute to the pollution of air, waters and soils. Also the use is sometimes dependent on the atmospheric conditions.
Germany was the first country to use chemical weapons during World War I, employing chlorine gas against Allied troops in April 1915.
Iraq
Chemical weapons are very dangerous and can destroy also the environmement; USA used chemical weapons in all the wars (Vietnam, Serbia, Irak, Afghanistan, etc.).
I know of no "nuclear biological" weapons, perhaps you meant nuclear, biological, chemical (NBC) weapons, which can be any one of these.

The UN has established treaties and conventions such as the Treaty on the Non-Proliferation of Nuclear Weapons, the Chemical Weapons Convention, and the Biological Weapons Convention to limit the spread and use of nuclear, biological, and chemical weapons. It also conducts inspections and monitoring programs to ensure compliance with these agreements and works with member states to strengthen their non-proliferation efforts.

Bioweapons can wipe out humans
The US has expressed a policy that they are OPPOSED to all forms of biological weapons.
Gas masks if they're extremely current and up to date ones. Also coverals if they're made of plasic and dont have any openings in it.
When biological weapons have been used the outcome has been massive death and biological destruction. It affects all things in the area used. When Hessian used biological weapons against his people whole populations died. Since it is biological it stays in the environment and can mutate so it has been agreed not to use them.
