Toxicity Identification Evaluation (TIE) Evaluation

Example of a Toxicity Identification Evaluation Plan

TIE testing is performed when a facility is seeing consistent results indicating toxicity and has not been able to determine the cause.  This can be difficult because:

  • multiple potential toxicants may be present

  • little or no toxicity data exist for many compounds

  • toxicity is frequently variable, and

  • the sample matrix may greatly modify toxicity


We can tailor a TIE which incorporates identification methods appropriate for the specific situation and thus provides the most economical and expeditious solution to the toxicity problem. 

  • Surfactants

  • Polymers

  • Metals

  • Ion imbalance

  • Fish pathogens

  • Oxidants

  • Ammonia

  • Pesticides

Some examples of causitive toxicants include:
