This clearly shows the greater effect of biological degradation
(in both physical and chemical ways) on the clearcoat having lower [T.
About two-thirds of agricultural land has been degraded over the past 50 years by erosion, salinization, soil compaction, nutrient depletion, biological degradation
, and pollution.
The resistance to biological degradation
of composite wood products is improved by applying a suitable aqueous dispersion of zinc borate onto the fibers to uniformly distribute and to adhere the zinc borate to the strands of the wood composite, applying a suitable adhesive to the wood strands, forming a strand lay-up and consolidating a lay-up under heat and pressure to form a consolidated product with zinc borate uniformly distributed therethrough.
Last August, EKOR was certified by the Ukrainian government where testing acknowledged its lack of chemical or biological degradation
even after long-term exposure to radiation.
The change in colour is due to biological degradation
effected by the bacteria in the bottom of the channels into which the wastewater is discharged.
This relatively rapid flow did not encounter the same degree of retardation, chemical adsorption, and biological degradation
as normally occurs when fluids seep slowly through soil.
Rheological agents in the coating slurry promote the even flow of the coating over the pattern, and the preservatives and bactericides retard deterioration of organic ingredients from biological degradation
Over time, biological degradation
processes ultimately reduce the contaminants to harmless end products.
PVC's superior durability can be attributed to its resistance to biological degradation
from bacteria and other microorganisms.
The present project presents solutions to the biological degradation
as described above from which the development outcome would be improved national capacity to monitor environmental conditions and trends and to assess policy performance in promoting environmental sustainability.
