Selenium Uptake by Plants from Soils Amended with Inorganic and Organic Materials

Metal availability and uptake by sorghum plants grown in soils amended with sludge from different treatments.

Several factors depending on the sludge, the soil, or the combination of both substrates, may affect element availability to plants. In this study, an assessment was done of the effect of two sludges obtained by different processes (activated sludge and facultative stabilization pond) on heavy-metal availability and uptake by sorghum plants in soils with high and low copper contents. Results ob...

Selenium in Soils and Plants

Sorption, degradation and leaching of pesticides in soils amended with organic matter: A review

The use of pesticides in modern agriculture is unavoidable because they are required to control weeds. Pesticides are poisonous; hence, they are dangerous if misused. Understanding the fate of pesticides will be useful to use them safely. Therefore, contaminations of water and soil resources could be avoided. The fates of pesticides in soils are influenced by their sorption, decomposition and m...

Mimicking tricks from nature with sensory organic–inorganic hybrid materials

Design strategies for (bio)chemical systems that are inspired by nature’s accomplishments in system design and operation on various levels of complexity are increasingly gaining in importance. Within the broad field of biomimetic chemistry, this article highlights various attempts toward improved and sophisticated sensory materials that rely on the combination of supramolecular (bio)chemical re...

Uptake, Metabolism, and Volatilization of Selenium by Terrestrial Plants

Selenium (Se) in irrigation drainage water became a major concern after it was implicated in deaths and deformities of waterfowl at Kesterson Reservoir (Presser and Ohlendorf 1987; Ohlendorf 1989). Subsequently, other areas with irrigationinduced Se problems (or potential problems) have been identified in several western U.S. states (Seiler 1995), reinforcing the status of Se as a U.S. Environm...
