The Toxi-ChromoPad test is designed for Rapid Detection of Acute Toxicity during Contact. The Toxi-ChromoPad bioassay uses a novel mutant of the bacterium E.coli as the test organism. This bacterium was selected specifically for sensitivity to a wide range of toxic substances.

The assay allows the bacteria to grow in direct contact with the toxicants in the sample, eliminating expensive extraction procedures. The endpoint of the assay is an easy to interpret colour reaction. If the sample is toxic, no colour will develop; if the sample is non-toxic, a distinctive blue colour develops around the sample.

The Toxi-ChromoPad is a bioassay screening tool used to determine acute toxicity in soils, sediments, sludge or other solid waste materials directly without extraction.

Each kit contains all the reagents and disposable materials necessary to test at least four samples, including dilutions and controls.

Used within Universities across North America, the Toxi-ChromoPad kit can be tailored to meet the demands of any university student. Used in support of a graduate thesis, or as a learning tool for laboratory use at the undergraduate level.

The Toxi-ChromoPad offers the following advantages over traditional methods:

Testing of industrial solid effluents for presence of possible toxic compounds.

Screening of municipal soils for possible routine presence or spills of toxic compounds.

Evaluation of pure or complexed raw mixtures for potential toxicity in sediments.

A convenient and easy to use teaching look for university and college laboratories.

The Toxi-ChromoPad kit is designed to be user friendly, reliable, sensitive, rapid, low cost and contains all plastics needed to complete the assay.

Blow is an example of the Toxi-ChromoTest.

Disc 1(center dot is a control) A series of 8-2 fold serial dilutions were carried out on the pad ranging from pure sludge to less than 1%. At a concentration of 0.8% the sample showed no toxicity

Disc 2 – The same test carried out on a different sludge sample. In this case toxicity disappeared at a 6% concentration showing this sample was 10X less toxic
