This may be due to the high variance in the total amount of substances within the two groups, which is partly explained by the fact that different halictid species were included in the analysis.
The guidelines require determination of the deposition rate and the use of a breath simulator for determination of the active substance delivery rate and total amount of active substance delivered.
In the assessment of the detriment from inhaled substances, the overall collective intake commitment is simply the total amount of each substance ever to be inhaled, irrespective of when or where.
But Mr. Bramblett said the initial weight included containers and paraphernalia ("that's the stuff you smoke it in, or whatever, or a roach, whatever that is"), and that the total amount of the substance was about three ounces.
Due to the magnitude of renal blood flow the total amount of noxious substance delivered may be disproportionately high.
Bioaccessibility can be defined as the fraction of the total amount of a substance released from the soil during digestion.
Focusing on the total amount of all substances, as in EM- MFA, provides useful information, and analysis of a specific substance provides different, and also useful, information.
EC values approximately capture the total amount of dissolved substances in water.
When the researchers compared their results against records of drug-related criminal activity, they found that airborne concentrations of cocaine correlated with the amount of drugs seized by police; R2 values were 0.54 for cocaine seizures and 0.73 for the total amount of illicit substances.
As has been demonstrated in P. triangulum, it is the increased proportion of unsaturated HCs, rather than the total amount of cuticular substances, that is crucial for the change in physicochemical properties and the resulting antimicrobial effect of prey embalming [ 18].
The total amount of cuticular substances on provisioned bees was, on average, twice as high as on control bees; however, this difference was statistically not significant (8.7 ± 6.5 μg vs. 4.1 ± 3.9 μg; Mann–Whitney U test, N provisioned bees = 6, N controls = 9, U = 12, exact p = 0.09).
