Cadmium (Cd) is a toxic heavy metal that enters the environment through various anthropogenic sources, and inhibits plant growth and development. Cadmium toxicity may result from disturbance in plant metabolism as a consequence of disturbance in the uptake and translocation of mineral nutrients. Plant nutrients and Cd compete for the same transporters and, therefore, presence of Cd results in m...

We describe a vision for national-scale heavy mineral (HM) map generated through automated mineralogical identification and quantification of HMs contained in floodplain sediments from large catchments covering most Australia. The composition the reflects dominant rock types each catchment, with generally resistant largely preserving fingerprint their host protoliths weathering-transport-deposi...

The mining industry located along the fall line region of central Georgia has been and remains as one of the largest global exporters of the clay mineral kaolinite. Among the kaolin deposits in that region, the Cretaceous Buffalo Creek formation and the Eocene Jeffersonville member contain the most commercially viable kaolin to extract and process for resale. The minerals of the sand and silt f...

A field experiment was carried out to study the effect of application rates of sewage sludge and mineral nitrogen and phosphate fertilizers on As, Ba, Cd, Cr, Cu, Ni, Pb, Se, and Zn concentration in soil, cane plant, and first ratoon (residual effect) in a Typic Hapludult soil. To allow an analysis by means of response surface modeling, four rates of sewage sludge (0, 3.6, 7.2 and 10.8 t ha(-1)...

Plants are sessile organisms therefore, cannot avoid adverse environmental conditions (such as soil salinity, drought, heat, cold, flooding and heavy metal contamination). These stress factors are a menace for plants, prevent them from reaching their full genetic potential and limit crop productivity worldwide. Soil contamination with heavy metals has become a world wide problem leading to loss...

The red sand which is known as Teri sand in Tamil Nadu consists of 5.5% Total Heavy Minerals (THM) out of which 3.7% is ilmenite. The other minerals, zircon, sillimanite and garnet are in the order of abundance identified. On processing this feed to recover ilmenite by using spirals followed by dry high intensity magnetic separator and high tension separator, the ilmenite concentrate obtained c...

OBJECTIVES Determine particulate matter (PM10) and heavy metals concentrations in the environment, as well as in surrounding communities of the Las Bambas project after five years of mineral exploration. MATERIALS AND METHODS A comparative cross-sectional study was conducted in three districts in the area of influence of the Las Bambas project in Apurimac, Peru. Samples of water, air and soil...
