International Lead Poisoning Prevention Week takes place from October 18 to 24. This year, the initiative calls for a shift from detection to prevention. For Pure Earth Mexico, this is an opportunity to strengthen the conversation about sources of lead exposure and, above all, the actions that can help reduce it.
Lead is a toxic substance that can harm people’s health, especially during childhood. Exposure can occur through various sources found in homes, communities, and workplaces. Identifying these sources is an important first step, but prevention requires understanding how exposure occurs and developing solutions that can truly be applied in each context.

A Public Health Challenge
In Mexico, lead’s impact on people’s health is an issue that requires attention. An integrated analysis of the 2022–2024 ENSANUT Continuous Survey found that 15.8% of children between the ages of 1 and 4 have lead poisoning—a proportion equivalent to approximately 1.2 million children.
These figures help show the scale of the challenge and underscore the need for information that can help identify sources of exposure and guide prevention efforts.
One of the main sources identified in the country is the use of glazed clay cookware coated with lead-containing glazes, although other sources are associated with certain production activities, products, and contaminated sites.

Moving Toward Solutions
Reducing lead exposure means addressing its sources directly. In the case of pottery, for example, this involves supporting artisan communities in adopting lead-free glazes and processes, while recognizing the economic and cultural importance of this activity.
This work requires collaboration among communities, government authorities, academic institutions, businesses, and civil society organizations. For Pure Earth Mexico, generating evidence, sharing knowledge, and supporting the implementation of safe alternatives are essential to building communities with lower levels of lead exposure.
Prevention also depends on getting information to those who can make decisions. Understanding the risks helps families, producers, workers, and institutions identify practices that can be changed and seek safer alternatives.
As part of International Lead Poisoning Prevention Week 2026, Pure Earth is creating opportunities to share experiences and strengthen collaboration across Latin America.
On October 20, the regional webinar “Latin America United Against Lead: Experiences to Protect Health and the Environment” will bring together representatives from Colombia, Mexico, Peru, and Brazil. The event will explore regional experiences and strategies to reduce lead exposure and strengthen prevention capacity.
Moving from detection to prevention means turning data into decisions and decisions into action. In Mexico, where millions of children face this risk, progress depends on keeping the issue on the agenda and strengthening solutions that are already underway.
During this week, Pure Earth Mexico reaffirms its commitment to working with communities, institutions, and partners to identify sources of exposure and promote alternatives that can reduce contact with lead.
Prevention begins with information, but it requires sustained action and ongoing collaboration.
