Regional Screening Levels (RSLs) User's Guide Risk

The author of the IRIS assessment for manganese recommended that the dietary contribution from the normal U.S. diet (an upper limit of 5 mg/day) be subtracted when evaluating non-food (e.g., drinking water or soil) exposures to manganese, leading to a RfD of 0.071 mg/kg-day for non-food items.

Safe Levels Heavy Metals and Gardens

The U.S. Environmental Protection Agency (U.S. EPA) and many Public Health agencies have published what they consider to be "safe levels" of certain metals in soil based on their own research or that of other organizations. Unfortunately, these organizations do not always agree on what is safe, and "safe levels" specifically for gardens where food is grown can be higher than what is considered

Mass, Weight, Density or Specific Gravity of Bulk Materials

As 1000kg of pure water = 1 cubic metre, those materials under 1000kg/cu.m will float; more dense will sink ie. those materials with a specific gravity more than 1. Pure water was chosen as the 'base line' for specific gravity and given the value of 1. The specific gravity of all other materials are compared to water as a fraction heavier or lighter density.
