All scientists can use principles from chemistry, as chemistry is the study of matter and the changes it undergoes. Here are some examples of scientific fields that may use principles from chemistry:

- Biochemistry: The study of the chemical processes that occur in living organisms.

- Environmental science: The study of the environment, including the chemical composition of air, water, and soil.

- Geology: The study of the Earth, including the chemical composition of rocks and minerals.

- Materials science: The study of the properties and uses of materials, including the chemical composition and structure of materials.

- Pharmacology: The study of the effects of drugs on the body, including the chemical synthesis and properties of drugs.

- Physics: The study of matter and energy, including the chemical reactions that occur when energy is released.

- Toxicology: The study of the effects of toxic substances on living organisms, including the chemical composition and properties of toxins.
