Low-sulfur diet - Wikipedia

A low-sulfur diet is a diet with reduced sulfur content. Sulfur containing compounds may also be referred to as thiols or mercaptans. Important dietary sources of sulfur and sulfur containing compounds may be classified as essential mineral (e.g. elemental sulfur), essential amino acid and semi-essential amino acid (e.g. cysteine).

Given the known differences in chemical behavior between the various sulfur types, the probability of obtaining a significant correlation between asphalt performance versus concentration of a specific sulfur type is much greater than one versus total sulfur content.

Arsenic | Minerals Education Coalition

Arsenic metal very rarely occurs in its pure form in nature. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur. Several other, less-common minerals contain arsenic, including orpiment, realgar, and enargite, which are arsenic sulfides. Most arsenic is obtained not from an ore mineral of arsenic, but as a ...

Sulfur and Nitrogen Content | FSC 432: Petroleum Refining

Sulfur content is expressed as weight percent of sulfur in oil and typically varies in the range from 0.1 to 5.0%wt. The standard methods that are use to measure the sulfur content are ASTM D129, D1552, and D2622, depending on the sulfur level. Crude oils with more than 0.5%wt sulfur need to be treated extensively during petroleum refining.
