Chemical materials (pure or impure) can be pollutants for waters, soils and air.
Yes, most matter in the environment exists as mixtures rather than pure substances. Mixtures are composed of two or more different substances physically combined, such as air, soil, and seawater, which contain a variety of elements and compounds mixed together.
Cheese is a pure substance
No, pure substances cannot be mixtures. A pure substance is made up of only one type of atom or molecule, with uniform properties throughout the sample. Mixtures, on the other hand, are composed of two or more different substances physically combined, each retaining its individual properties.
Drugs may be pure substances but more frequently they are mixtures.
Pure substances are different from mixtures in that they have a fixed composition and uniform chemical properties throughout. In contrast, mixtures are combinations of two or more substances that can vary in composition and may have varying properties at different parts of the mixture.
Mixtures
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
Mixtures are more common in the world compared to pure substances. Mixtures are combinations of two or more substances that can be physically separated, whereas pure substances are composed of only one type of substance and cannot be separated by physical means.

pure substances and mixtures
Mixtures and pure substances are both made up of different types of matter. However, mixtures contain two or more substances physically combined, while pure substances contain only one type of substance with a specific composition.
Compounds and solutions are pure substances
Matter can be divided into two categories: pure substances and mixtures. Pure substances are made up of only one type of atom or molecule, while mixtures are composed of two or more different substances that are physically combined.
Matter is classified as mixtures and substances. Mixtures are composed of two or more different substances that are physically combined, while substances are pure forms of matter that cannot be separated by physical means. Substances are further divided into elements and compounds.
Most substances around us are mixtures, rather than pure substances. Mixtures are composed of two or more substances that are physically combined and can be separated by physical means, while pure substances are made up of only one type of particle. Examples of mixtures include air, sea water, and soil.
A mixture contain two or more pure substances.
