Six artist materials and their environmental impact

We recently wrote about the toxicity of artist acrylic paints and their impact on the environment. In general they are considered less toxic when compared to other types of paints, such as oil-based paints or certain solvents. In follow up to that article here are some artist materials that require a deliberate and considered approach to their use but more importantly in their disposal. 

1. Oil-based paints

Oil paints contain pigments suspended in an oil-based binder, typically linseed oil. The production and disposal of oil paints can contribute to air and water pollution. Additionally, the cleanup of oil-based paints requires the use of solvents such as turpentine or mineral spirits, which are toxic and can release volatile organic compounds (VOCs) into the air.

2. Solvents

Solvents are commonly used in art for thinning paints, cleaning brushes, and removing paint. Solvents like turpentine, mineral spirits, and paint thinners are volatile and release harmful VOCs into the atmosphere, contributing to air pollution. Improper disposal of solvent waste can contaminate soil and water sources.

3. Spray paints

Spray paints contain pigments and a propellant that allows the paint to be sprayed in a fine mist. The propellants in aerosol spray paints are typically hydrocarbons or compressed gases, which can contribute to air pollution. Inhalation of spray paint fumes can also be harmful to human health.

4. Heavy metal-based pigments

Some pigments used in art contain heavy metals such as lead, cadmium, chromium, and mercury. These pigments can pose environmental hazards, especially during their production and disposal. Heavy metals can leach into the soil and water, causing pollution and potentially harming ecosystems.

5. Printmaking materials

Certain printmaking techniques involve the use of chemicals such as etching acids (e.g., nitric acid) and solvents (e.g., mineral spirits) for plate preparation, cleaning, and ink removal. Improper disposal of these chemicals can be harmful to the environment.

6. Sculpting materials

Certain sculpting materials, such as polyester resins and epoxy resins, contain chemicals that can be harmful to the environment if not handled and disposed of properly. These materials can release VOCs during curing and may require special waste management practices.

It's important to note that while some art materials have a more significant environmental impact, proper usage, disposal, and waste management practices can help mitigate their harm.

It's always advisable to follow manufacturer instructions, use environmentally friendly alternatives when available, and dispose of art materials according to local regulations to minimize their impact on the environment.
