Very bad and so wide in variety depending on agent(s) used that I have no hope of even beginning to enumerate them here - even if I spent a whole week doing nothing but typing them. Sorry. I will give a short list:
Since US doctrine during the Vietnam War was:
1. Retention of nuclear first strike capability.
2. Right to retaliate with chemical weapons.
3. Will not use bio weapons.
Probably Bio wpns were worse since the US refused to use them (during the cold war).
They make people sick. Exact effect would depend on disease organism used in weapon. The Soviets once designed, built, and tested a biological weapon that only caused a mild flu like disease, but once you got over that it immunized you against yourself and your own immune system proceeded to kill you.
No Because Chile Isn't All in On Biological Weapons.
I know of no "nuclear biological" weapons, perhaps you meant nuclear, biological, chemical (NBC) weapons, which can be any one of these.
Nuclear weapons weapons of mass destruction, biological weapons.
There are many places where one could find information on biological weapons. One could check 'Ready' for information on biological weapons and threats.

Nuclear weapons, Biological Weapons, Chemical Weapons.
anthrax and botulin toxin.
A biothreat is a threat from biological weapons.
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.
Wars using biological agents as weapons.
