High doses of a test chemical sometimes affect the food consumption of the treated animals even to the point of starvation. The effect of such a non-specific toxicological stress on the bone marrow micronucleus test was investigated in male and female Sprague-Dawley rats.
A 42
-h starvation had a noticeable effect on the ratio of polychromatic to normochromatic erythrocytes (
PCE
and NCE); the values in the starved animals were approx. 77% of the negative controls. An effect of starvation on the frequency of micronucleated erythrocytes (MN-E) was not discernable from the results of the present experiment.

Two industrial polycarboxylate superplasticizer samples have been selected to be used within the Priority Program 2005 of the German Research Foundation (DFG SPP 2005). The
PCE
polymers were characterized via Size Exclusion Chromatography (SEC) to determine their molar masses (
M
w
, M
n
), the polydispersity index (PDI) and the conversion rate which indicates the incorporation of the macromonomer into the polymer. The anionic charge amount of the
PCE
samples was assessed via charge titration employing a cationic polymer. Furthermore, the cement dispersing properties of the
PCE
polymers were captured via 'mini slump' tests so as to assess their ability to fluidize CEM I 42.5 R and CEM III/
A 42
.5 N samples, respectively. Also, interaction between the PCEs and the surface of the cements was investigated via adsorption and zeta potential measurements of aqueous cement suspensions. The results shall be used for the ongoing research within the Priority Program.
