... The naturally occurring element selenium (Se) is essential to human and animal
health, in trace amounts, but can be harmful in excess. The intake range between
dietary deficiency and excess is very narrow (UK Lower Reference Nutrient Intake

... The Alder-Reilly anomaly is associated with the genetic mucopolysaccharidoses. Patients with mucopolysaccharidoses lack the lysozymal
enzymes necessary to break down mucopolysaccharides. Dense azurophilic

Dioxins and dioxin-like compounds
Dioxins and dioxin-like compounds (DLCs) are by-products of various industrial processes, and are commonly regarded as highly toxic compounds that are environmental pollutants and persistent organic pollutants (POPs). They include: Polychlorinated dibenzo-p-dioxins (PCDDs), or simply dioxins. PCDDs are derivatives of dibenzo-p-dioxin. There are 75 PCDDs, and seven of them are specifically toxic. Polychlorinated dibenzofurans (PCDFs), or furans. PCDFs are derivatives of dibenzofuran. There are 135 congeners (derivatives differing only in the number and location of chlorine atoms). Whilst they strictly speaking are not dioxins, ten of them have ""dioxin-like"" properties. Polychlorinated biphenyls (PCBs), which also are not dioxins, but twelve of them have ""dioxin-like"" properties. Under certain conditions PCBs may form dibenzofurans through partial oxidation. Finally, dioxin may refer to dioxin proper, the basic chemical unit of the more complex dioxins. This simple compound is not persistent and has no PCDD-like toxicity
