Environmental Laboratories

DHI has fully equipped environmental laboratories with an experienced staff of technicians, biologists, engineers and chemists. Our laboratory expertise is based on more than 25 years of studies and tests within the fields of biology, chemistry, ecotoxicology and microbiology for industry, authorities and international research programs. Chemical analyses (e.g. of disinfection by-products) are performed via agreement between DHI and skilled analytical laboratories accredited for the required services.

Our laboratories hold accreditation according to ISO 17025, which includes biological and physicochemical analyses and ecotoxicological tests applied in the biological performance evaluation of ballast water management systems. 

Examples of DHI’s laboratory services include:

  • Biological analyses of live phyto- and zooplankton
  • Microbiological analyses of E. coli, enterococci and Vibrio cholerae
  • Ecotoxicological studies according to ISO standards, OECD guidelines or OSPAR Convention protocols
  • Production and sale of phytoplankton pigment and cyanobacteria toxin standards
