Interestingly, numerous phylotypes decreased in abundance following CBZ exposure and these varied with soil type, concentration, duration of exposure, and the availability of oxygen.
We examined the effect of precursors (ammonium molybdate, sodium sulphide and citric acid) concentration, duration and the temperature on the morphology of the product.
Statistically designed experiments were carried out to study the effect of processing conditions, such as photoinitiator concentration, duration of irradiation, UV lamp intensity, cooling air pressure, and photoinitiator type, on rheological properties, molecular weight characteristics and branching level.
Selenium exposure was varied during a 21-d chronic toxicity test to examine the effects of exposure concentration, duration, and recovery on survival, growth, and reproduction of D. magna.
In addition, the possible toxic effect of NPs depends on their concentration, duration of their interaction with living matter, their stability in biological fluids, and the capacity for accumulation in tissues and organs.
It is reported that the biodistribution of carbon nanomaterials depends strongly on various factors such as nanoparticle size, type of functionalization, concentration, duration of exposure, administration method, and even dispersant [5 11].
The accumulation of Pb increased in a concentration-duration-dependent manner, however its translocation from root to shoot was low.
Sediment rating curves are essential tools for the calculation of sediment load, concentration-duration curve (CDC), and concentration duration frequency (CDF) analysis for more accurate assessment of water quality for ungauged basins.
