Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

ABSTRACT: The objective of this meta-analytical study was to investigate selected

11

macrominerals, microminerals, and toxic heavy metals in the bovine whole raw milk samples

12

of published data. An analytical dataset was constructed from 72 different studies from 37

13

countries with two types of production systems: conventional production system (CPS) and

14

organic production system (OPS) compared to commercially or retail store available milk

15

(COM). Results of the meta-analytical study showed differences in the concentrations of

16

macrominerals. Concentrations of Ca, , Mg, K, and P were greater in the CPS whereas Na was

17

greater in COM (P
