1、Designation: F 1209 08Standard Guide forEcological Considerations for the Use of Oil SpillDispersants in Freshwater and Other Inland Environments,Ponds and Sloughs1This standard is issued under the fixed designation F 1209; the number immediately following the designation indicates the year oforigin
2、al adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the use of oil spill dispersants to assistin t
3、he control of oil spills. The guide is written with the goal ofminimizing the environmental impacts of oil spills; this goal isthe basis on which the recommendations are made. Aestheticand socioeconomic factors are not considered, although theseand other factors are often important in spill response
4、.1.2 Spill responders have available several means to controlor clean up spilled oil. In this guide, the use of dispersants isgiven equal consideration with other spill countermeasures. Itis not considered as a “last resort” after all other methods havefailed.1.3 This is a general guide only. It ass
5、umes the oil to bedispersible and the dispersant to be effective, available, appliedcorrectly, and in compliance with relevant government regula-tions. In the assessment of environmental sensitivity, it isassumed that the dispersant is nonpersistent in the naturalenvironment. Oil, as used in this gu
6、ide, includes crude oils andrefined petroleum products. Differences between individualdispersants or between different oil products are not consid-ered.1.4 The guide is organized by habitat type, for example,small ponds and lakes, rivers and streams, and land. Itconsiders the use of dispersants prim
7、arily to protect habitatsfrom impact (or to minimize impacts).1.5 This guide applies only to freshwater and other inlandenvironments. It does not consider the direct application ofdispersants to subsurface waters.1.6 In making dispersant use decisions, appropriate govern-ment authorities should be c
8、onsulted as required by law.1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations

Thestudies have involved both intentional experimental spills andstudies undertaken during actual spill situa
16、tions (1-6).35.2 There have been a number of studies on the impact of oiland oil/dispersant mixtures on microbiological systems andplankton (7-16).5.3 The principal biotic components of such water bodiesare a variety of fauna and flora. The aquatic flora include algae(planktonic and attached) and fl
17、oating or submerged vascularplants. Terrestrial flora include grasses, moss, lichens, herbs,forbs, and woody plants.5.4 The fauna include invertebrates (molluscs, crustaceans,worms), fish, a variety of waterfowl and seabirds (ducks, loons,gulls, terns, and herons), mammals, such as beaver andmuskrat
18、, and in many areas, significant human activity. Therehave been some studies on the effects of oil and oil/dispersantmixtures on fauna (17, 18). The distribution and compositionof species is a function of climate, local geography and soiltype, and human use of the area (19).5.5 Studies of the effect
19、s of oil on vegetation includelaboratory work on the effects on willows, moss, lichen, blackspruce, and sedge. These studies showed that the pouring of oildirectly on the vegetation was lethal to willow and moss, andcaused some nonpermanent damage to the other species(20-29).5.6 Floating leaves are
20、wetted and penetrated by oil fromslicks while younger floating leaves whose cuticles are intactare more resistant to penetration by oil. Penetration occursmost readily in areas where there is damage to the leaf causedby insects or mechanical abrasion.5.7 Oil is retained in areas of dense vegetation
21、and isreleased slowly. Dispersants applied soon after a spill appear tospeed the movement of the slick through the vegetation if thereis some water movement. Only the oil that contacts the leavescauses some damage. Leaves and stems that are subsurface arenot damaged by the presence of oil. Oil slick
22、s that are restrictedto contact of the stem areas near the water surface are not veryinjurious.5.8 Field studies in northern environments have shown littlelong term effects of spilled oil. There have been few studies onthe effects of dispersed oil in these environments.5.9 Although oil may cause ext
23、ensive damage to vegetationgrowing in low-lying wetlands and shorelines of bog lakes,plants that grow from rhizomes or healthy portions of aerialtissue (sedge and willow) have a high recovery potential.Long-term damage to root systems could, however, slowrecovery of the vegetation in impacted areas.
24、 This may be ofless importance in areas with an elevated water table (boglakes).5.10 Laboratory studies of the foliar damage to moss,lichen, willow, blackspruce, and sedge by dispersants indicatesome damage, but this is generally not lethal. Plants treatedwith dispersants recover in most cases. Howe
