Assessment and Significance of Sediment-Associated Oil and Grease in Aquatic Environments


Book Description

A review of the literature suggests that the term 'oil and grease', as used in descriptive and regulatory context for dredged material disposal, is a broadly based term defined by the methodology used in its determination. Oil and grease contains numerous natural and petroleum derived hydrocarbons, plus fats, oil, and waxes of both natural and anthropogenic origin. Also included in oil and grease are trace quantities of fat-soluble materials such as DDT and PCB. Elemental sulfur is a contaminant often included in oil and grease determinations by virtue of its solubility in some organic solvents. Although some oil and grease fractions are readily degraded by microbiological action, many petroleum hydrocarbons are resistant to decomposition. Little is known concerning the effects of sediment-associated oil and grease on organisms and ecosystems, although in the case of certain oil spills it is known that toxic oily residues can be retained over periods of years in sediments with little abatement of their toxic properties.

Seafood Regulations Compliance Manual


Book Description

A first of its kind, the Seafood Regulatory Compliance Manual is a comprehensive work that comprises the myriad of governmental requirements and guidelines applicable to all aspects of seafood from harvest to the marketplace. The intent of the authors was to develop for users a manual that is easy to use, with a structured format to ensure compliance with governmental requirements. They have been highly successful in achieving this objective and presenting a user friendly tool. The manual represents a major advancement by providing a single source reference to all requirements, except for some specific end product and labeling requirements, for a highly complex global industry. In addition, it is an outstanding contribution to the seafood industry in addressing a long-standing need for systems changes in the form of a single source manual, in contrast to the obsolete approach of having to access a library of multiple regulations and the affiliated agencies' bureaucracies to determine how and/or whether compliance with a particular regulation has been achieved. For those engaged in international commerce in seafood, the manual should be especially useful. Well integrated throughout the manual are the applicable provisions of the recommended international Codex standards for fish and shellfish products and the codes of hygienic and technological practice for handling and processing these products. These standards and codes were developed through an international harmonization process, and are familiar to seafood-producing countries worldwide.
