The concentrations of sixteen elements and organic carbon were determined in 78 marine sediment samples collected from the Iranian coastal waters of the Persian Gulf. Nine transects perpendicular to the coastline were sampled. Sixteen elements, including As, Ba, Cd, Co, Cu, Mn, Ni, Pb, Zn (trace metals) and Ca, Fe, Mg, Na, P, S, Si (major metals), were determined by Inductively Coupled Plasma M...

The water quality of the Persian Gulf is influenced by various industrial and urban discharges. The study area is a small linked estuary with the Straits of Hormuz in the Persian Gulf. This study was conducted to evaluate anthropogenic assessment, pollution status and potential ecological risk of some heavy metals (Pb,Ni, Zn, and Fe) in intertidal surface sediments of a mangrove estua...

both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the imandra lake (the largest subarctic lake at kola peninsula, russia) were investigated during the 1990 - 2003 period. we used different indexes of solar activity (sunspot numbers and uv- radiation values) as heliophysical factors. information about uv- radiation values was derived from satellite...

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Printer-friendly Version Interactive Discussion EGU Abstract Subsurface temperatures in Bangkok, where population and density increase rapidly, were analyzed to evaluate the effects of surface warming due to urbanization. The magnitude of surface warming evaluated from subsurface temperature in Bangkok was 1.7 • C w...

in recent years, the topic of desertification has been discussed in different ways in scientific areas. this event occurred globally, regionally and nationally and many steps were taken to stop it. desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. the identification of sensitive regions and prevention ...
