How Do Toxic Substances Contribute to Depression?

Toxic substances, including heavy metals, pesticides, and industrial chemicals, can have profound effects on the brain and nervous system. Chronic exposure to these substances can lead to neuroinflammation, oxidative stress, and disruption of neurotransmitter systems, all of which are implicated in the development of depression. For example, lead exposure has been linked to alterations in serotonin and dopamine pathways, which are critical for mood regulation.
