Foreign material that is added to air or bodies of water are called pollutants. Examples would be smog, oil, smoke, and trash.

Well if the processing is milling flour, then the raw material is called "grist".

DNA ligase
are called dopants
The fossilization process you are referring to is called replacement. This occurs when the original material of an organism is dissolved and replaced by minerals, leaving a replica of the organism's shape.
Animals that contain foreign DNA are called transgenic or genetically modified organisms (GMOs). This DNA is often added to confer specific traits, such as disease resistance or improved growth characteristics.
A plant can express a bacterial gene that has been added to its genome because plants have the ability to take up and incorporate foreign DNA into their own genetic material through a process called genetic engineering. This allows the plant to produce the protein encoded by the bacterial gene, which can confer new traits or characteristics to the plant.
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
New material was likely added to planets in a young solar system through processes like accretion and impacts from asteroids and comets. These small bodies collided with the growing planets, contributing to their mass and composition. Over time, these collisions helped shape the planets and their eventual characteristics.
Impurities can be incorporated into a crystal structure through a process called doping, where foreign atoms are intentionally added during crystal growth. These impurities can occupy lattice sites, forming substitutional defects, or they can be present in between lattice sites, creating interstitial defects. Doping can alter the electronic and optical properties of the material, making it useful for various applications.
Americans will buy fewer foreign products.
