1、Designation: F 1209 89 (Reapproved 1999)Standard Guide forEcological Considerations for the Use of OilspillDispersants 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
2、the year oforiginal 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 oilspill dispersan
3、ts to assistin the 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 socio-economic factors are not considered, although theseand other factors are often important
4、in spill response.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 g
5、uide only. It assumes 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, a
6、s used in this guide, 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
7、 dispersants primarily to protect habitatsfrom impact (or to minimize impacts) and to clean them aftera spill takes place.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 us
8、e decisions, appropriate govern-ment authorities should be consulted 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
9、 and determine the applica-bility of regulatory limitations prior to use.2. Significance and Use2.1 This guide is meant to aid local and regional responseteams who may use it during spill response planning and spillevents.2.2 This guide should be adapted to site specific circum-stance.3. Environment
10、 CoveredPonds and Sloughs3.1 Ponds and sloughs are small isolated water bodies thatare not part of major water systems. They have a dynamicecology, and a wide mixture of animal and plant species. Innorthern regions, these water bodies may freeze to the bottomand do not sustain a wide variety of aqua
11、tic species.3.2 While most of these bodies are naturally occurring andexist throughout the year, some may be man-made. In aridclimates, the existence of these bodies may be seasonal.3.3 The characteristics of these water bodies are:(a) Open water area of less than 10 hectares,(b) Shallow water with
12、a maximum depth of 1 to 1.5 m,(c) Soft bottom with a high organic content,(d) May have alkaline or acidic water,(e) No well defined inlet or outlet, and(f) Poorly defined shoreline consisting of floating mats ofvegetation.4. Background4.1 The effects of oil and dispersed oil on these aquaticenvironm
13、ents have been the subject of numerous studies. Thestudies have involved both intentional experimental spills andstudies undertaken during actual spill situations (1-5).24.2 There have been a number of studies on the impact of oiland oil/dispersant mixtures on microbiological systems (6-15).4.3 The
14、principal biotic components of such water bodiesare a variety of fauna and flora. The aquatic flora includebacteria, algae, (planktonic and attached), and floating orsubmerged vascular plants. Terrestrial flora include grasses,moss, lichens, herbs, forbs, and woody plants.4.4 The fauna include inver
15、tebrates, (zooplankton, mol-luscs, crustaceans, worms, and other similar species), fish, avariety of waterfowl, (ducks, loons, gulls, terns, and herons),1This guide is under the jurisdiction of ASTM Committee F-20 on HazardousSubstances and Oil Spill Responseand is the direct responsibility of Subco

17、krat, and in many areas,significant human activity. The distribution and composition ofspecies is a function of climate, local geography and soil type,and human use of the area (16).4.5 Studies of the effects of oil on vegetation includelaboratory work on the effects on willows, moss, lichen, blacks
18、pruce, 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(17-26).4.6 Floating leaves are wetted and penetrated by oil fromslicks while younger leaves whose cuticles are intact are mo
19、reresistant to penetration by oil. Penetration occurs most readilyin areas where there is damage to the leaf caused by insects ormechanical abrasion.4.7 Oil is retained in areas of dense vegetation and isreleased slowly. Dispersants applied soon after a spill appear tospeed the movement of the slick
20、 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 slicks that are restrictedto contact of the stem areas near the water surface are not veryinjurious.4.8 Fie
21、ld 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.4.9 Although oil may cause extensive damage to vegetationgrowing in low lying wetlands and shorelines of bog lakes,plants that grow
22、from rhizomes or healthy portions of aerialtissue (sedge and willow), have a high recovery potential. Longterm damage to root systems could however slow recovery ofthe vegetation in impacted areas. This may be of less impor-tance in areas with an elevated water table (bog lakes).4.10 Laboratory stud
23、ies of the foliar damage to moss,lichen, willow, blackspruce and sedge, by dispersants indicatesome damage, but this is generally not lethal. Many dispersantsare fast acting contact poisons, but their activity is limited tothe site of application. Plants treated with dispersants recoverin most cases
24、. However foliar damage may increase the plantssusceptibility to pathogens.4.11 Field studies on the effects of the direct spraying ofplants with dispersants indicated that the short term effect ofdispersants to individual plants was less than that incurredthrough natural causes. No long term effect
