OCTOBER 2004 AMERICAN METEOROLOGICAL SOCIETY | A erosols are airborne suspensions of tiny particles, each typically about one-thousandth the diameter of the period at the end of this sentence. Cumulatively, they have profound effects at a variety of scales, exerting myriad influences on the earth’s environment and climate and on human health. Many aerosols originate from natural sources—volcano...

Human activities can create noise pollution and there is increasing international concern about how this may impact wildlife. There is evidence that anthropogenic noise may have detrimental effects on behaviour and physiology in many species but there are few examples of experiments showing how fitness may be directly affected. Here we use a split-brood, counterbalanced, field experiment to inv...

Arsenic (As) toxicity in soil and water is an increasing menace around the globe. Its concentration both in soil and environment is due to natural and anthropogenic activities. Rising arsenic concentrations in groundwater is alarming due to the health risks to plants, animals, and human beings. Anthropogenic As contamination of soil may result from mining, milling, and smelting of copper, lead,...

Terrain surfaces conserve human activities in terms of textures and structures. The objective of geomorphological filters is to distinguish between anthropogenically undisturbed and disturbed surfaces. Filters applied over high-resolution DTM show a clear anthropogenic character of contour lines and channels. Based on methodology of geomorphometry and geo-statistics a series of analyses functio...

Environmental pollution due to heavy metals like mercury is of serious concern throughout the world. Due to anthropogenic activities, the concentration of mercury has increased in the environment. Though many methods are available for mercury removal, adsorption is considered as simple, economical and versatile method. In this paper the efficiency of mercury removal from aqueous solution using ...
