The Need

Faced with a variety of requirements to meet new environmental compliance, specifically ship and port based ballast water management practices, the maritime industry needs new tools, methods, and skills for biological reporting. Crewmembers are critical to compliance actions, and crews change frequently, so training must be consistently available. Utilizing innovative prognostic tools to ensure water quality standards are met, these market needs are international, universal; with the lowest cost of operations achieved by consistent application of optimized best practices.

We have taken industry standards and embedded them in the measurement, sampling handling, statistical analysis, and data collection processes. The QwikLite® 200 Biosensor System uses patented methods to rapidly determine toxicity of potential contaminants of both inorganic and organic varieties.

The testing process is simple and can be done in any temperate location. State of the art miniature optics and electronics are used to analyze each sample separately. Quality control and sample integrity are ensured via the bar coded disposable test kits, menu driven guidance of EPA methods and laboratory procedures, and industry standards for completing reports. These include:

  1. EPA procedures and requirements for sampling methods and measurements are part of the Assure QwikLite® 200 Biosensor System, and follow EPA Methods for Measuring Acute Toxicity EPA-821-R-02-012, -013, -014.
  2. Bioluminescence: total light emitted and spectral characteristics of selected species of marine plankton is measured and compared to a standard or control sample in each test.


Protection of aquatic species requires prevention of unacceptable effects on populations in natural habitats from harmful contaminants of organic, inorganic components; as well as heavy metals. Therefore, toxicity tests are conducted to provide data to detect toxicity and predict what changes in the survival of individual species might result from similar exposure (or continued exposure) in the natural habit. Information might also be obtained on the effects of the material on the health of other species.

A critical component of the Clean Water Act (and all environmental programs) requires all stakeholders to employ best management practices (BMPs). These are a series of repeatable processes applicable to the project or study. As such BMPs are techniques used to manage and control activities, maintain quality and consistency, and in the most cost-effective manner.

Bioluminescent dinoflagellates represent an important eucaryotic group (having a nucleus and complex cellular structures) which have been present for 3.5 billion years and are widely distributed in the environment. The endpoint for ASTM E1924 testing (QwikLite) is based on a measurable reduction or inhibition in light output from the dinoflagellates. When bioluminescent dinoflagellates are exposed to toxicants, a measurable reduction in bioluminescence is observed from their cells following mechanical stimulation when compared to control cells.

This toxicity detection method uses a portable instrument to measure the light output of the organism after they have been exposed to water samples. If there are harmful contaminants, bioluminescence is reduced in a predictable and measurable relationship (as toxicity increases, light decreases). The rapid toxicity test provides results in 24 hours or less and all tested samples are compared to a control group. This method is useful in screening of water bodies for toxicity or water quality due to contaminants (organic, inorganic, and heavy metals), as well as baseline assessment applications. Regular and frequent monitoring will provide more consistent and efficient use of resources in toxicity identification projects and/or remediation plans.
