Environmental Monitoring and
Assessment Standing Committee
(EM&A)
Chemicals Management Forum
San Antonio, Texas
May 15-16, 2012
Commission for Environmental Cooperation
Background
• 1999: North American Regional Action Plan (NARAP) on
Environmental Monitoring and Assessment (EM&A) in support of
the SMOC initiative that, among other things, promotes
collaboration in acquiring environmental data and information to
assess exposure to substances of concern and the risks they pose
to human health and the environment
• 2008: Develop and implement a sustainable regional approach to
environmental and human biomonitoring and assessment to
enhance North American monitoring capacity, with an early
emphasis on supporting Mexico in the initial stages of
implementation of its National Environmental Monitoring and
Assessment Program (Programa Nacional de Monitoreo y
Evaluación Ambiental—Proname)
• 2010: The EMA SC supports the Sound Management of
Chemicals Working Group in “…continental management of
chemicals of concern.”
2
What it does
• Serve as a trinational forum for promoting
cooperation and sharing knowledge in monitoring
and assessing persistent toxic substances in the
North American environment
• Work to improve the comparability, quality,
relevance and availability of environmental
information on the status, trends of persistent
toxic substances
• Direct beneficiaries are governments, academics
and private laboratories in Mexico
3
Objectives and Goals of EM&A
• Assist the Parties in increasing the comparability,
reliability, relevance and availability of data and
information on chemicals
• Seek to improve the information needed to identify
and assess trends and concerns related to
contaminants and stressors that affect the
environment and human health
• In order to ensure an integrated North American data
set, place continued emphasis on supporting Mexico’s
monitoring and evaluation program (Programa
Nacional de Monitoreo y Evaluación Ambiental—
Proname)

Training: e.g., POPs in environmental matrices
Workshops: e.g., Chemical data analysis, modelling
atmospheric fate and transport
Intercalibration exercises: e.g., Atmospheric
chemistry
Lab validation exercises: e.g., Developed guidelines
for interlaboratory validation
Guidance documents: e.g., Biomonitoring
initiatives

North American Trilateral Maternal Blood Study
The purpose of this sampling was to obtain an initial
profile of levels of persistent organic pollutants (POPs)
and metals in pregnant women from Canada, Mexico
and the United States.
SAMPLING SITES
Results:
•As expected, mothers from Mexico had higher
concentrations of p,p’-DDT and p,p’-DDE due to
its more recent use in Mexico. Lower
concentrations of PCBs were seen in Mexican
mothers compared to those in Canada and the
United States.
•In Mexico, it was found that mothers of
Coatzacoalcos, a center of the Mexican
petrochemical industry, had the highest
concentration of several POPs (p,p´-DDE p,p´DDT, PCDDs)
•Merida, an urban area without major sources of
contaminant exposure, had higher concentrations
of several PCB congeners
Conclusion
This study provides an indication of the concentrations of POPs/metals in pregnant women in North
America and Mexico, plus the need for an ongoing surveillance program among vulnerable
populations to pinpoint sources of higher exposure.

Mexican ecosystems, through a long-term
(more than 25 years) national
environmental-biological monitoring
program that contributes to ecosystem and
human health.

POPs Air Monitoring Program
• The POPs Air Monitoring Program is being implemented
under the Proname umbrella, which in turn:
– Fulfills the commitments established within the CEC
EM&A working group
– Supplies POP data for the Global Monitoring Plan
(GMP) under the Stockholm Convention
– Includes five sites:
• Two form part of the Global Atmospheric Passive
Sampling Network (GAPS).

Next Steps for EM&A
Next Steps
Contribute to advancing sound management of
chemicals:
- Support Proname at two new sites
- Continue support of research needs on specific
chemicals, such as mercury deposition and dioxin
monitoring
- Continue support to Mexico as it develops its
biomonitoring programs
- Generate a report on SMOC contributions to
SAICM for ICCM3
25
Challenges
• Consolidate a network of analytical laboratories
in Mexico
• Consolidate chemical specific monitoring into
overall Proname
• Share methodologies to identify communities
and ecosystems at risk
• Interpretation and evaluation of data, including
data comparison at a regional level and how
best use the current data available
• Increase transparency by sharing results with
stakeholders
