Abstract:
Southern Mediterranean lagoons are considered among the systems most vulnerable to anthropogenic activities. In its present condition, the Mar Menor lagoon in south-eastern Spain must be considered as degraded as a result of the pressures to which its shoreline is exposed. These include the transport of arsenic from nearby mining areas, linked to soluble or particulate run-off following rainfall events and flooding. This work studies the solubility and bioavailability of arsenic in the soils of watercourses that drain into the Mar Menor, using nine single chemical extractions with different reagents. The values obtained for As, as well as for Fe and Mn, throw light on the interactions of these metals with As and predict future behaviour patterns for different scenarios. The mineral composition is seen to significantly influence the mobility of the studied elements and shows the relation between the soils and materials of mining origin. It has been suggested that the sediments deposited in the in the watercourses or "ramblas" that transport these materials may act as foci of dispersion.

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
Parameters Affecting Nonlinear Elimination: Zero-Order Input, First-Order Absorption and Two-Compartment Model
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...
