Randomized trial assesses soil contamination and human health risks from cement production in Bokajan, highlighting environmental concerns.

This study aims to evaluate potentially toxic element contamination in soil and its associated health risks around a cement factory.
Analyzed 36 surface soil samples for Pb, As, Cr, Co, Ni, and Zn using X-ray fluorescence.
Generated spatial distribution maps using inverse distance weighting (IDW) in ArcGIS 10.8.2.
Assessed health risks through ingestion, inhalation, and dermal pathways based on USEPA models.
Mean concentrations of PTEs were below Canadian soil quality guideline values.
Cancer risk from Cr exceeded USEPA threshold for adults (1.46 × 10−5) and children (5.18 × 10−6).
Noncarcinogenic risks were generally low, except for elevated HI values for As and Cr in children.

Brahma et al. (2026) studied this question.
