The toxicant is added to the water in order to obtain the correct concentrations to be tested.

The possibility of loss of toxicant due to volatilization, adsorption, degradation, and uptake is reduced.

The choice of cell system, toxicant concentration and exposure time must all be carefully considered.

Early evidence indicates that schisandrin B can protect liver against toxicant challenge .

Since the concentration for both drugs are not toxicant to cells, the drug specific differentiation is not due to selection but induction of cells.

The repeatability or precision of toxicity tests is also a function of the number of test organisms used at each toxicant concentration.

For example, when the data are analyzed by hypothesis testing, the nonparametric alternatives cannot be used unless there are at least four replicates at each toxicant concentration.

Using these six concepts Pagenkopf looked at copper, zinc, cadmium, lead, combinations of metals, and hydrogen ion concentration using effective toxicant concentration.

If the numbers of data points for each toxicant concentration are not equal, the Wilcoxon Rank Sum Test with Bonferroni's adjustment should be used (see Appendix F).

"The law only requires that a cosmetic manufacturer with a product that contains a toxicant report it," said Kevin Reilly, deputy director of prevention services of the state's public health program.

There are substantial activities in using in vitro systems to advance mechanistic understanding of toxicant activities, and the use of human cells and tissue to define human-specific toxic effects.

"Our findings suggest that reduction of toxicant exposures may be an important avenue for ADHD prevention and they underscore the enormous burden that may be associated with continued exposure to tobacco and lead," the researchers conclude.

The types of control charts illustrated (see USEPA, 1979a) are used to evaluate the cumulative trend of results from a series of samples, thus reference toxicant test results should not be used as a de facto criterion for rejection of individual effluent or receiving water tests.

For practical reasons, the responses observed in these tests are usually limited to hatchability, gross morphological abnormalities, survival, growth, and reproduction, and the results of the tests are usually expressed in terms of the highest toxicant concentration that has no statistically significant observed effect on these responses, when compared to the controls.
