Form 7 Peer reviews were not required for this proposal because it is an Interagency agreement and a service agreement. The National Science Foundation (NSF) Proposal and Award Manual states in section 122 .2.(B) that peer review is not applicable for " services provided by another Federal agency in support of Polar Programs" 9314735 Petty The Fish and Wildlife Sevice will further develop and test lipid dosimeters or semipermeable membrane devices for use in Antarctica. The dosimeter is essentially a semipermeable plastic tube containing triolein (a lipid). The device is designed to be placed insitu in water and simulate the uptake of contaminants by aquatic biota. The contaminants in the lipid are extracted and analyzed by conventional analytical methods. The advantages of the technique are 1) deployment of the dosimeter is much simpler than collecting aquatic biota; 2)data between sampling locations are comparable whereas data from different species are not; 3). divers are not needed; 4) aquatic biota are not harvested; and 5). sample holding time are probably extend. ***

表格7本提案不需要同行评审，因为它是一个机构间协议和服务协议。美国国家科学基金会（NSF）的提案和奖励手册在第122.2节中规定。(B)同行评议不适用于“其他联邦机构为支持极地项目提供的服务”9314735佩蒂鱼类和野生动物管理局将进一步开发和测试用于南极洲的脂质剂量计或半透膜装置。剂量计本质上是一个含有三油酸（一种脂质）的半透塑料管。该装置被设计放置在水中，模拟水生生物对污染物的吸收。用常规的分析方法提取和分析脂质中的污染物。该技术的优点是：1)使用剂量计比收集水生生物群要简单得多；2)采样地点之间的数据具有可比性，而不同物种的数据则不具有可比性；3).不需要潜水员；4)水生生物群未被捕捞；5)试样保温时间可能延长。＊＊＊
