Neurodevelopmental impact of mining-related contamination in children from the Sonora river basin.

ABSTRACT:

Introduction

In August 2014, the Buenavista del Cobre mine in northern Mexico released over 40,000 m³ of acidified copper sulfate into the Sonora River, causing long-term environmental contamination. Children in nearby communities face increased neurodevelopmental risks due to prolonged exposure to toxic metals such as lead and arsenic. This study examines cognitive and executive functioning outcomes in exposed children, considering the roles of nutrition, parenting practices, and prenatal biological risk factors.

Methods

A cross-sectional study was conducted with 238 children aged 5-13 years: 215 from mining-impacted communities and 23 from the non-exposed control community of Álamos. Children completed selected BANETA neuropsychological subtests (e.g., attention
