Examples and expertise

NIWA has wide-ranging expertise in toxicology testing.

Examples of commercial and research toxicity testing:

  • new pesticides for wastewater treatment ponds    
  • evaluation of effluent treatment strategies
  • risk assessment of emerging chemicals of concern
  • risk assessment of mine leachates into freshwater streams
  • development of site-specific guidelines for contaminants (ANZECC methodology)
  • literature and database search for novel piscicides (pest fish control
  • compounds) suitable for New Zealand
  • design and implementation of monitoring programmes to comply with resource
  • consent conditions of marine and freshwater sewage outfalls
  • registration of herbicides with ERMA
  • dredge spoil toxicity
  • assessment of storm-water toxicity in urban streams
