Acosta y Asociados (AyA) was contracted by the Commission of Environmental Cooperation to prepare a preliminary inventory of atmospheric emissions of mercury (Hg) from stationary sources in Mexico for the year of 1999. We have attempted to methodically carry out both primary and secondary research to build upon two previous studies of mercury air emissions and mercury-enriched sites in Mexico: the 1997 EPRI study coordinated by Bill Powers of Powers Engineering (39) and the May 2000 draft INE study coordinated by Jose Castro from (Toxic Materials Directorate) (21). Mr. Powers was a subcontractor on this study and the Principal Investigator Gildardo Acosta worked very closely with Mr. Castro.
DDT was first registered in 1946 and used in Canada to control insect pests in crops as well as in domestic and industrial applications. DDT was never manufactured in Canada. In response to environmental and safety concerns, most uses of DDT were phased out by the mid-1970s. Registration of all remaining uses of DDT was […]
Canada, Mexico and the United States will be among more than 100 nations to sign a historic environmental treaty today in Stockholm that will phase out use of a dozen of the most dangerous toxic chemicals on the planet. This historic agreement will deliver a healthier world for people and wildlife, from the arctic regions of Alaska and the Canadian north, to the tropical climes of Mexico—and around the world.
On 22-23 May 2001, the environment ministers or their representatives from the three NAFTA countries, along with their counterparts from around the world, will congregate in Stockholm, Sweden, to formally adopt and sign an international agreement to minimize and eliminate persistent organic pollutants (POPs), some of the most toxic substances ever created by human beings. […]
Today, more people, commodities and products, more ideas and images, more genes and microbes, will move around the planet than at any other time in human history.
This paper has been prepared as background document for the Special Session on Tools That Use PRTR Data, which will take place on 6 March 2001 in Mexico City. The session is part of the annual Meeting of the Consultative Group for the North American Pollutant Release and Transfer Register (PRTR) Project, organized by the […]
This document has been prepared as an aid for participants in the Roundtable Discussion on Opportunities and Challenges of Pollutant Release and Transfer Register Reporting in Mexico. The meeting is hosted by the North American Commission for Environmental Cooperation (NACEC). Given the importance placed on the further development of the Mexican PRTR program by members […]
This report summarizes actions to be taken and progress to date in implementing the North American Regional Action Plan on Chlordane (NARAP-Chlordane). The objective of that NARAP is to reduce human and environmental exposure to this compound through discontinuation of its currently authorized uses.
Trade between Canada, the United States and Mexico has grown rapidly since the implementation of the North American Free Trade Agreement (NAFTA). This study examines the environmental impacts of that trade on five bi-national segments of three primary NAFTA trade corridors, with a particular focus on air pollution emissions. The corridor segments selected for the […]
In a groundbreaking NACEC study conducted by a team led by scientist Barry Commoner of the Center for the Biology of Natural Systems (CBNS), dioxins falling in the new polar territory of Nunavut are linked to their source regions thousands of kilometers away.
This study set out to model on a continental scale the rates of deposition of airborne dioxin (polychlorinated dibenzo-pdioxins and polychlorinated dibenzofurans, PCDD/PCDF) in the new Canadian polar territory of Nunavut and to identify the major contributing North American sources.
