MRI: Acquisition of Radiochemical Mass Balance Equipment for Environmental Engineering

[02:16 . 06]这个提议是为了获得可用于测量碳-14同位素的仪器。该设备将支持西雅图大学土木与环境工程系的本科生研究活动。本研究旨在研究植物对炸药RDX（六氢-1,3,5-三硝基-1,3,5-三嗪）和HMX（八氢-1,3,5,7-四硝基-1,3,5,7-四氮辛）的吸收和转化。所要求的设备将能够对[U- 14c]RDX和[U- 14c]HMX进行质量平衡，这反过来将决定爆炸物在植物组织中的运输和命运。先前的植物吸收研究表明，RDX和HMX在植物组织的叶片中积累的不良倾向，转化速度缓慢。本项目将探索减少RDX和HMX在植物体内积累的两种途径，从而提高植物修复这些化合物的适用性。

The equipment will support undergraduate research activities in Seattle University's Department of Civil and Environmental Engineering. The research activities discussed in this proposal seek to study uptake and transformation of the explosives RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) and HMX (octahydro-1,3,5,7- tetranitro-1,3,5,7-tetrazocine) by plants. The requested equipment will enable mass balances on [U- 14 C]RDX and [U- 14 C]HMX to be performed which will in turn determine the transport and fate of the explosives in plant tissues. Previous plant uptake studies with RDX and HMX have indicated an undesirable tendency to accumulate in the leaves of plant tissues with slow rates of transformation. This project will explore two ways in which to decrease RDX and HMX accumulation in plants and thus increase the applicability of phytoremediation of these compounds.
