E3: Solubility Constants for Compounds at 25°C
Although all compounds have a characteristic solubility in water at a given temperature, some families of compounds are more soluble than others and it is useful to know certain general rules of solubility. We call any substance insoluble its solubility is less than 0.01 mol/L. If its solubility is greater than 0.1 mol/L, we call it soluble.

Rethinking mercury: the role of selenium in the pathophysiology
Introduction: There is increasing evidence that the pathophysiological target of mercury is in fact selenium, rather than the covalent binding of mercury to sulfur in the body's ubiquitous sulfhydryl groups. The role of selenium in mercury poisoning is multifaceted, bidirectional, and central to understanding the target organ toxicity of mercury.
