including tropical and temperate climate regions across the western U.S., Brazil, Australia, South Africa, Europe, and Indonesia, and therefore may be a natural source of metals during fire conditions (Fig.1). The frequency of large (greater than 2023 ha, Fig.1) and small (Supplementary...
Fruit and vegetable wastes (FVW) are produced in large quantities in markets and constitute a source of nuisance in municipal landfills because of their high biodegradability1. It has been documented that the wastage of fruit contains a major portion of citrus peels, with a world production estima...
In addition, the biogeochemical processes responsible for Cu, Zn, and Pb cycling at background levels and their fates once introduced to the lakes remain unclear and constitute an urgent knowledge gap for large-scale and long-term water quality management, as well as for the assessment of ...
After preparation of the "button" specimens, there was a thin layer of oxide on the svirface which was easily removed by f i l i n g * When the specimens were broken with a mortar and pestle a l l of them were found to be extremely b r i t t l e . Small pieces, about 100...
The obtained SPAN compound was further dried in vacuum overnight and then manually ground using a mortar and a pestle to reduce the particle size of the SPAN particles. The SPAN particles were sieved by a 63μm sieve to ensure a homogeneous particle size distribution. Elemental analysis of ...

This study compared state of pollution around an intermediate treatment plant of industrial wastes before and after the change of its treatment procedure. Bulk atmospheric deposition, surface soil, suspended particulate matter and groundwater were collected after the plant changed main operation to waste...
The glass of this example may be considered to be a chloroborophosphate. In this case, the chlorine also played a significant role in rendering soluble in the melt the relatively large amount of zinc oxide present. EXAMPLE 2 A glass was prepared from this batch formulation: Zinc Oxide 57.13...
