- (Biyoloji) precursor
- That which precurses, a forerunner, a predecessor, an indicator of approaching events
- {n} a forerunner, harbinger, courier
- a forerunner or herald
- An air pressure wave which moves ahead of the main blast wave for some distance as a result of a nuclear (or atomic) explosion of appropriate yield and low burst height over a heat-absorbing (or dusty) surface The pressure at the precursor front increases more gradually than in a true (or ideal) shock wave, so that the behavior in the precursor region is said to be nonideal See Blast wave, Shock front, Shock wave
- starts a chain reaction which accelerates growth
- a person who goes before or announces the coming of another a substance from which another substance is formed (especially by a metabolic reaction)
- A substance that precedes, and is the source of, another substance
- In photochemistry, a compound antecedent to a pollutant For example, volatile organic com- pounds (VOCs) and nitric oxides of nitrogen react in sunlight to form ozone or other photochemical oxidants As such, VOCs and oxides of nitrogen are precursors
- the reactants used in industrial semiconductor manufacture to make the desired product; for instance, ArH3 is often the precursor for the Arsenic in GaAs devices
- a substance from which another substance is formed (especially by a metabolic reaction)

- Any directly emitted pollutant that, when released into the atmosphere, forms or causes to be formed or contributes to the formation of a secondary pollutant for which an ambient air quality standard has been adopted, or whose presence in the atmosphere will contribute to the violation of one or more ambient air quality standards
- For carbon fibers, the rayon, PAN or pitch fibers from which carbon fibers are made
- A chemical compound which is released into the atmosphere, undergoes a chemical change, and leads to a new (secondary) pollutant VOCs are precursors to ozone
- Any chemical reactant which takes part at any stage in the production by whatever method of a toxic chemical
- a substance that is used as a building block for another
- One who, or that which, precedes an event, and indicates its approach; a forerunner; a harbinger
- {i} precedent, antecedent; predecessor (in a job or position); herald or harbinger; announcer, crier
- Either the PAN or pitch fibers from which carbon and graphite fibers are derived
