Characterizing the speciation of iodine in groundwater is essential for understanding its hydrogeochemical behavior in aquifer systems. To quantify the variations in iodine speciation and assess factors controlling the distribution and transformation of iodine, 82 groundwater samples and 1 rain water were collected from the Datong basin, northern China in this study. Factor analysis (FA) and ex...

As in other countries, the effects of human stressors on coastal areas and waters in Nigeria are increasing, and management strategies are urgent. In order to assess this, studies on phytoplankton composition in relation to physico-chemical characteristic of two tidal creeks in Lagos were conducted for six months (October 2007 to March 2008). Variations in some of the physical and chemical para...

The field of eDNA is growing exponentially in response to the need for detecting rare and invasive species management conservation decisions. Developing technologies standard protocols within biosecurity sector must address myriad challenges associated with marine environments, including salinity, temperature, advective deposition processes, hydrochemistry pH, contaminating agents. These approa...

All source information for the tasks of effective management water resources is based on results observations and measurements, ie monitoring. Despite apparent advantages assessing surface quality using comprehensive indicators, creation about 30 most well-known indicators since first attempts in this field hydrochemistry to date, only indicator that combines assessment natural masses different...

Accurately quantifying biodiversity is fundamental for both evolutionary theory and conservation strategies. DNA-based studies are exposing high cryptic diversity irrespective of taxonomic group or environmental setting, and increasing the ever-growing estimates of global biodiversity. This has severe implications for under-sampled and species-rich tropical regions, such as the Amazon Basin. We...

To better understand the mechanisms that hydrological conditions control chemical weathering and carbon dynamics in the large rivers, we investigated hydrochemistry and carbon isotopic compositions of dissolved inorganic carbon (DIC) based on high-frequency sampling in the Wujiang River draining the carbonate area in southwestern China. Concentrations of major dissolved solute do not strictly f...

[1] Groundwater biogeochemistry is adversely impacted when municipal solid waste leachate, rich in nutrients and anthropogenic compounds, percolates into the subsurface from leaking landfills. Detecting leachate contamination using statistical techniques is challenging because well strategies or analytical techniques may be insufficient for detecting low levels of groundwater contamination. We ...
