The Marine Management Organisation (MMO), an executive non-departmental public body, sponsored by DEFRA, has published comprehensive guidelines on the chemical analysis of sediment samples which need to be carried out in support of marine licensing applications.

The guidelines explain which chemical species need to be measured and includes:

  • polychlorinated biphenyls (PCBs)
  • polycyclic aromatic hydrocarbons (PAHs)
  • organochlorine pesticides
  • brominated flame retardants such as polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)
  • other chlorobiphenyls
  • organophosphorus pesticides
  • petroleum hydrocarbons
  • other organotin compounds
  • other anti-fouling agents
  • polychlorinated dibenzodioxins or polychlorinated dibenzofurans
  • radiological analysis

Trace metals are also included in the guidance.

The guidance makes clear that quality assurance carried out should include the use of a certified reference material (CRM) or in-house reference material (IHRM) with very batch, as well as the acceptable precision and recovery values, depending on the concentrations of the contaminants found.

Overall, excellent guidance which is comprehensive and easy to understand. The QA section is welcomed, but no reference has been made to laboratories being accredited to ISO/IEC 17025, which is somewhat surprising in the context of the guidance given.
