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.
Some relevant information such as mercury content of smelters feedstock, heavy fuel oil, diesel fuel and carbon, required to estimate mercury emissions from potentially important sources, such as smelters and utilities, was directly requested by through an official letter of request. No information has been received as per the date of closing this report. The project team has to rely then in information directly obtained through interviews or by indirect approaches.
