Guideline for Elemental Impurities 2 46 This guideline does not apply to drug products used during clinical research stages of 47 development. In the later stages of development, the principles contained in this 48 guideline can be useful in evaluating elemental impurities that may be present in new drug product prepared by the proposed commercial process.
The Nutritional Relationships of Manganese plants, dry cell battery, and fuel oil industry. The first reports of manganese toxicity were made by Couper in 1837.24 He described a condition similar to paralysis agitans in pyrolusite mill workers. Greater attention to manganese toxicity developed in the 1930's and 40's following

a Silicon-Manganese addition. Following tap, heats are treated at a Ladle Metallurgy Facility (LMF). At the LMF, slag additions and modifiers are used to work the slag and trap inclusions. Alloy additions are made at the LMF, as well as re-heating the steel for further processing or shipment to the caster.
Filtration 1 Filtration . Filtration plays an important role in the natural treatment of groundwater as it percolates through the soil. It is also a major part of most water treatment.

Manganese is a naturally-occurring element that can be found ubiquitously in the air, soil, and water. Manganese is an essential nutrient for humans and animals. Adverse health effects can be caused by inadequate intake or over exposure. Manganese deficiency in humans is thought to be rare because manganese is present in many common foods.
Manganese greensand is one of the most common medium in use for removing of iron and manganese, through pressure filtration. Commercial products that can be found on the market for removal of iron, manganese and hydrogen sulfide are: Greensand, Greensand Plus and Filtersorb FMH. The basis of Greensand makes glauconite, whereas the ba-

effects of residual sulfur. However, silicon and manganese can be added in amounts greater than those required strictly to meet these criteria so that arbitrary upper limits for these elements have to be set; usually, 0.60% for silicon and 1.65% for manganese are accepted as the limits for carbon steel.
