Description
Wendy Argelia García-Suastegui and co-authors screen suspended matter in Mexico's Atoyac River for polymer-like material, in a 2026 early study. The river receives industrial, farm, and household discharges along the studied stretch. Water came from six sites across a 43-kilometer section representing different land uses.
Infrared spectroscopy, sharpened by math-based separation of overlapping signals, found bands matching common plastics such as polyethylene and polystyrene types. A strong signal near textile sites pointed to sulfonated compounds linked with dyes. The authors stress that, without removing organic matter first, results suggest polymer-like signs rather than proving tiny plastic particles. Still, the method offers a fast screening baseline for a heavily polluted river.
