The phrase "accumulated concentration" is correct and usable in written English.
It can be used in contexts discussing the buildup of focus or intensity over time, often in scientific or psychological discussions.
Example: "The accumulated concentration of pollutants in the water has reached alarming levels, prompting immediate action from environmental agencies."
Alternatives: "cumulative concentration" or "total concentration".
The accumulated concentration of H2 after 9 months of incubation is enough to possibly sustain the survival of some strains of methanogenic archaea [41] but the rates of formation are probably too low to sustain any growth.
The total accumulated concentration of zoledronic acid was 98 to 100 μg/kg/mouse, equivalent to the 4-mg clinical dose.
The mean accumulated concentration for UFP, PM2.5, PMcoarse, and PM10 fractions, measured on the different examination days between 0800 and 1000 hours, and the corresponding temperature from 0800 to 1000 hours are given in Figures 1 and 2. The mean relative humidity was 70.3% and 84.0% for the first and second sampling period, respectively.
Open image in new window Fig. 4 Accumulated concentration of heavy metals leached from porous concretes: a chromium, b lead, c cadmium, d arsenic, e copper and f mercury.
Those chemicals that have "hitched a ride on plastics" may sometimes be found "in accumulated concentrations that may be harmful to humans", says Halden.
There is no clear temperature dependence on the accumulated concentrations.
This suggests that XlnR responds to the presence of accumulated concentrations of l-arabinose or a conversion product.
However, factors that usually were taken into account include weather conditions, population density, time of day, and uncertainty about the chemicals involved and/or the accumulating concentrations in public areas.
We found that premalignant-MCF10 cells were capable of accumulating concentrations of copper similar to those found in patient tissues (Table 1) and contained at least 16 fold more copper than cells cultured in standard media.
In the process their fatty tissues accumulate concentrations of PCBs, methylmercury, and other contaminants at about 10 times the density of native mussels, giving the fish and waterfowl that feed on them an extra shot of biomagnified poison.
Although the two exposure regimes have the same mean O3 concentration and accumulated O3 concentration above 40 ppb (AOT40), our results show that O3 at CF100D reduced biomass and number of pods/plant more than O3 at CF100.
