Buzzi Unicem finds obvious shortcomings in the metal bioaccumulation study conducted in Barletta by Mr. Di Ciaula

With regard to the study by Mr. Agostino Di Ciaula, conducted at the Barletta cement plant and recently published in the "Exposure and Health" journal, Buzzi Unicem has taken note of the results and has begun a process of in-depth analysis, in order to carefully evaluate the findings of this study.

An initial analysis has revealed obvious shortcomings which could invalidate the study in question. It is therefore considered necessary for the competent authorities to assess the thesis presented in order to provide the public with the proper information.

By way of example, below are some aspects that should be highlighted:

• the emission fallout considered by the research does not reflect the actual situation;
• during the reference period, the kiln at the Barletta cement plant was not running for more than half of the time for air quality purposes;
• the data was published in a biased manner, which did not allow a full analysis of the situation observed;
• for several metals, the study found higher concentrations in the fingernails of children not subjected to the fallout from cement plant emissions;
• the biological samples on the fingernails are prone to external contamination, presenting important critical points in the assessment of environmental exposure in the absence of reliable comparison values. 

The document prepared by Buzzi Unicem will soon be shared with all the competent bodies, with a view to transparency and accountability.

The company reaffirms its commitment to protecting the health and well-being of the communities in which it operates and strives to address in-depth the concerns of many citizens, in everyone’s interest.
