Ingestion of magnesium hydroxide can cause stomach pain, diarrhea, and vomiting

Environmental Considerations:

1. Ecotoxicity: Magnesium hydroxide has low eco-toxicity, meaning it does not cause significant harm to aquatic or terrestrial ecosystems.

2. Disposal: Magnesium hydroxide is not biodegradable and can accumulate in the environment. Disposal methods should be carefully considered to prevent potential pollution.

3. Resource Intensity: Producing magnesium hydroxide requires significant amounts of energy and resources, which can have negative environmental implications.

Overall, while magnesium hydroxide is effective as a flame retardant, its potential health and environmental impacts should be taken into account when using it as a flame retardant. Alternative flame retardants that are safer and more environmentally friendly are being developed and should be considered as well.
