Climate variables including temperature, rainfall intensity, acidity, and lithological properties are among the most important factors affecting rock weathering. However, relative contribution of these four on weathering, especially chemical is still unclear. In this study, we carried out a series weathering-leaching simulations types badland sediments under controlled conditions two levels aci...

The increasing prevalence of respiratory diseases in Chinese children has focused attention on indoor environmental quality.

SYNOPSIS A study of the incidence of peptic ulcer amongst railway workers in various parts of India has shown that ulcer is more common in wet and humid areas than in the dry and arid regions. This observation is also supported by the ulcer incidence reported in other studies from India, Africa, and the West. Saliva appears to have an important role in the prevention of ulcer, because of its ri...

of meningococcal meningitis occur in areas with particular environmental characteristics. We present evidence that the relationship between the environment and the location of these epidemics is quantifiable and propose a model based on environmental variables to identify regions at risk for meningitis epidemics. These findings, which have substantial implications for directing surveillance act...
