CG counts are measured by either taking the most heavily labelled area of cytoplasm, or by taking an average of two to three random cytoplasmic grain counts adjacent to the nucleus. Other counting methods (e.g. whole cell counting) may be used if they can be justified (6).

If the sludge cannot be used on the day of collection, 50 ml of synthetic sewage is added to each litre of the activated sludge prepared as described above; this is then aerated overnight at 20 ± 2 oC. It is then kept aerated for use during the day.
Kui muda ei saa kasutada selle kogumise päeval, lisatakse 50 ml sünteetilist muda igale aktiivmuda kogusele, mis on valmistatud nagu eespool kirjeldatud; seda aereeritakse seejärel öö läbi 20 ± 2 oC ning aereerimist jätkatakse kogu päeva.

From Fig.1a the influence of the soil density appears obvious; for example, for a classical centrifugation of 3000 rpm the centrifugation time is approximately 240 min for 1,2 g cm3 soil density, while it is only 50 min for 2,0 g cm3.
Joonisel 1a on selgesti näha mulla tiheduse mõju; näiteks klassikalise 3000 rpm tsentrifuugimisel on tsentrifuugimise aeg ligikaudu 240 minutit, kui mulla tihedus on 1,2 g/cm3, ja vaid 50 minutit, kui tihedus on 2,0 g/cm3.
Similarly, from Fig 1b, for a classical centrifugation of 3000 rpm the centrifugation time is approximately 50 min for a length of the mixture of 10 cm and only seven min for a length of 1 cm.
Samamoodi näitab joonis 1b, et klassikalise 3000 rpm tsentrifuugimisel on tsentrifuugimise aeg ligikaudu 50 minutit, kui segu pikkus on 10 cm, ja vaid 7 minutit, kui pikkus on 1 cm.

For toxic substances, the highest concentration tested should not reduce survival below 5 to 10 %. Relatively water-insoluble substances should be tested up to their limit of solubility, using appropriate procedures. For freely water-soluble non-toxic substances, the upper concentration should be determined on a case by case basis. Incubation conditions The plates are incubated four to seven days at 28 to 30 oC in the dark. Spontaneous mutation frequencies Sub-cultures should be used with spontaneous mutation frequencies within the accepted normal range. Number of replicates
Kui kasutatakse madala mutatsioonitasemega markereid, nagu horn 3-10, tuleb alusklaaside arvu suurendada, et saada statistiliselt olulisi andmeid.
At least three replicate plates should be used per concentration for the assay of prototrophs produced by gene mutation and for cell viability. In the case of experiments using markers such as hom 3-10 with a low mutation rate, the number of plates used must be increased to provide statistically relevant data.

When using the pooled approach, the SI is obtained by dividing the pooled radioactive incorporation for each treatment group by the incorporation of the pooled vehicle control group; this yields a mean SI. When using the individual approach, the SI is derived by dividing the mean DPM/animal within each test substance group and the positive control group by the mean DPM/animal for the solvent/vehicle control group.
Kokkupandud proove kasutades saadakse SI, jagades iga katserühma kokkupandud radioaktiivne inkorporeerumine kandeaine-kontrollrühma kokkupandud inkorporeerumisega; selle tulemuseks on keskmine SI: Individuaalset lähenemist kasutades tuletatakse SI, jagades iga katseainerühma ja positiivse kontrollrühma keskmise DPM-i looma kohta lahusti-/kandeaine-kontrollrühma keskmise DPM-iga looma kohta.

Generally, the medium is ready for use after standing for 20 h, at the test temperature. Determine the concentration of dissolved oxygen for control purposes; the value should be about 9 mg/litre at 20 oC.
Kontrollimiseks määratakse lahustunud hapniku kontsentratsioon, mis peaks 20 oC juures olema umbes 9 mg/l.
Calculate the percentage biodegradability by dividing the specific BOD by the specific ThOD (calculated according to Appendix 2.2) or COD (determined by analysis, see Appendix 2.3), thus: BOD = mg O2
