Daphnia swimming activity parameters (median speed) under normal conditions (Vc) and with addition of toxicants (Vo); Median toxicity index value in a series of N experiments (A, %) Substance N Vc, cv/sec Vc, cm/sec A, % Potassium dichromate
has made it easier for the applied colorant to be seen from the other surface and also made the expected reflection to appear on either the interior or the exterior surface.
Neither of the reference toxins, Mevinphos (2000 [micro]g/ml) nor potassium dichromate
(800 [micro]g/ml) produced notable mortality compared to the negative controls in 4 h.
Then 1 ml of Potassium dichromate
reagent was added.
is one of the most common causes of dermatitis; chromium is highly likely to induce sensitization leading to dermatitis, especially of the hand and fore-arms, which is chronic and difficult to treat.
All oocysts in stool samples in this study were stored in potassium dichromate
5ml of potassium dichromate
solution was added to 1 ml of cell free culture filtrate and mixed well.
5% potassium dichromate
solution from persons in Lima and Iquitos with Cyclospora infection.
Chromosomal aberrations and morphological transformation in hamster embryonic cells treated with potassium dichromate
5 percent (w/v) aqueous potassium dichromate
solution and, following a brief microscopic examination of portions of the samples, shipped to Kansas State University.
technical, technological lame anhydride for the needs of the Kazan Aviation Plant.
In spring 1998, we returned to Wollega Province, collected additional stool samples from three species of primates (baboons, colobus, and African green monkeys [Cercopithecus aethiops]), and placed these samples in potassium dichromate
for subsequent biologic and molecular studies.
