This in situ study aimed to evaluate the protective effect of Tooth Mousse (GC) containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on human enamel erosion and to compare the difference in erosion between the anteriorly and posteriorly positioned human enamel.
The climatic instability, human disturbance, erosion and redeposition have resulted in a pedogenic regression over the tableland.
When airborne particulate matter (PM) settles, it can become resuspended by human activity, erosion and wind.
Human-induced erosion is one of the key factors leading to the soil degradation.
The recent human-induced erosion partly destroyed polycyclic Luvisols and exposed ancient subsurface pedosedimentary strata.
In the last 40 years, Earth has lost a third of its farmable land to human-caused erosion and pollution, The Guardian reports.
Mainly during the 1700s and 1800s, the salt marshes expanded atop a temporary bounty of sediment delivered to the estuary's shores as a result of human-induced erosion, the researchers contend.
Knowledge of the topography prior to human-induced erosion (paleotopography) in naturally stable landscapes is valuable for identifying vulnerable landscape positions and is required as starting point for erosion modelling exercises.
The establishment of a chronology of landscape-forming events in lowland and mid-altitude Tasmania, essential for assessing the relative importance of climatic and human influences on erosion, and for assessing present erosion risk, has been limited by the small number of ages obtained and limitations of dating methods.
Effects on local ecosystems are great, from pollution of station areas by human wastes to erosion from overgrazing by sheep and to decimation of bird populations by dogs and cats and of whale and fur-seal stocks by humans.
In the past century and under increased human pressure, renewed erosion is in evidence in the interior valleys and at the coast.
