Brazil pilot project

Title of the project: Pilot project aimed at validating the inventory guidance on polychlorinated naphthalenes (PCNs), hexachlorobutadiene (HCBD), and short-chain chlorinated paraffins (SCCPs) by undertaking preliminary inventories in identified sectors in Brazil.

Donor: European Union
Partners: Government of Brazil and SCRC Brazil
Duration: October 2018 to July 2019
Target countries: Government of Brazil, CETESB/SCRC Brazil


  • To validate the inventory guidance on polychlorinated naphthalenes (PCNs) and hexachlorobutadiene (HCBD);
  • To develop inventory of PCNs, PCBs in open application and SCCPs in major products
Expected outcomes:

A report identifying sectors relevant to PCNs/PCBs, and SCCPs in products, wastes and contaminated sites in Brazil.

  • A list and number of samples to be analyzed to identify the presence of these POPs
  • Results from initial sampling, screening, and analysis of selected samples.
  • Comments on the inventory guidance including gap analysis

Through desktop study, the objectives and scope of a qualitative inventory on PCNs, SCCPs and PCBs in open applications will be defined for Brazil.

Development of an appropriate analytical procedure

Samples (representative) from following open applications will be analyzed for PCNs, SCCPs, PCBs:

  • PVC cables and recycled PVC
  • Paints/coatings e.g. ships, swimming pools
  • Sealants/caulks and putty
  • Rubber (Chloroprene and other rubber)
  • Oils including waste oil
Samples (representative) from following closed applications will be analyzed:
  • Integrating PCBs monitoring for PCNs monitoring
  • Mixed waste oils from sectors with possible impact by PCNs and SCCPs.
Initial assessment of potential generation of unintentional PCNs in the country
  • Identify which of the sources might be present in the country
  • Compile initial information
Initial findings on potential PCNs (if possible also SCCPs) contaminated sites
  • Assessing potential PCNs contaminated sites in the country
  • Preparing an initial description of identified sites
Evaluate and provide comments on the PCNs inventory guidance
  • Any gaps, lacking clarity etc.
  • Any duplications
Stakeholder consultation on the findings as listed above to finalize the comments on the guidance
