Mexico Cracks Down on Toxic Waste Dumping
1 Feb
Summary
- Mexico fines hazardous waste processor $4.8m following investigations.
- New air monitoring system to track industrial heavy metal emissions.
- Contaminated soil samples showed lead levels 1,760 times US risk levels.

Mexico has announced a significant crackdown on industrial pollution, employing a range of new tactics following investigative reports. These measures include a $4.8 million fine against Zinc Nacional, a facility processing US hazardous waste, and the introduction of a novel industrial air-monitoring system across Latin America.
Earlier investigations uncovered severe heavy-metal contamination in neighborhoods surrounding Zinc Nacional in the Monterrey area. The reports highlighted that industrial emissions in the region exceeded those in many US states and contributed more carbon dioxide than nearly half the world's nations.
The new government initiative involves establishing a comprehensive atmospheric monitoring network to measure industrial emissions, including heavy metals. This represents a "watershed moment" for industrial regulatory compliance in Mexico, according to Mariana Boy Tamborrell, Mexico's federal attorney for environmental protection.
Zinc Nacional is mandated to implement 24 corrective actions. These include relocating some operations, constructing new containment and water treatment facilities, remediating contaminated land, and reforesting 12 acres. The company has also acknowledged some contamination on its land.
Despite these actions, some local residents expressed disappointment, feeling the government's focus remained within the plant's boundaries and did not fully address health concerns in surrounding neighborhoods. Soil samples from near the plant revealed concerning levels of lead, cadmium, and arsenic in residential areas and schools.
In parallel, environmental regulators are updating outdated air and soil contamination standards, with industrial air-pollution standards set to lower particulate matter emissions by 50%. Senator Waldo Fernández is also drafting legislation to restrict toxic waste imports and mandate monitoring of heavy metal emissions.
Citizen groups are also taking action, with one petitioning for air standards aligned with international guidelines and another filing a lawsuit demanding an investigation into regional industrial air emissions. These efforts underscore the broad public concern regarding air quality and health in Monterrey.
Thousands in Monterrey are estimated to die annually from air pollution, with many more suffering from chronic illnesses. The impact of pollution affects everyone in the metropolitan area, regardless of socioeconomic status.
