Abstract: Zero valent metal composite, manufacturing thereof, using thereof, and system including thereof, for (in-situ or ex-situ) catalytically treating contaminated water, such as sub-surface water, surface water, above-surface water, water vapor, or/and gaseous water. Composite includes powdered diatomite matrix incorporated with nanometer (1-1000 nm) sized particles of a zero valent (transition) metal (iron, cobalt, nickel, copper, zinc, palladium, platinum, or/and gold) and at least one electron transfer mediator (catalyst) from porphyrinogenic organometallic complexes (e.g., metalloporphyrins (chlorophylls, hemes, cytochromes) or metallocorrins (e.g., vitamin B12), and optionally, includes vermiculite. System includes composite and in-situ or/and ex-situ unit containing the composite, enabling exposure of contaminated water thereto. Applicable to in-situ sub-surface permeable reactive barriers (PRBs). Treatable water contaminants are organics (halogenated organic compounds), or/and inorganics (metal elements, metal element containing inorganic species, nonmetal elements, and nonmetal element containing inorganic species). Applicable to non-aqueous fluids (liquids, vapors, gases), for removing contaminants therefrom.

Abstract: Method of exposing agricultural substrates (plant matter 10, animal matter 12) to agrochemicals (A); method of decreasing or preventing sub-surface geological matter (20, 22) contamination resulting from exposing agricultural substrates to agrochemicals; composition [(A)/(T)] 30 used therein; article-of-manufacture including the composition. Includes exposing agricultural substrates to composition including combination (mixture) of an agrochemical and at least one transforming agent capable of decreasing or eliminating concentration of the agrochemical which contacts sub-surface geological matter (at temporally varying times, and at spatially varying depths). Before entering sub-surface geological matter, transforming agent exhibits inactivity for decreasing agrochemical concentration, and inactivity for affecting or/and interfering with agrochemical functionality with respect to agricultural substrates. Transforming agent co-migrates and is co-distributed with agrochemical within and throughout sub-surface geological matter, and exhibits activity for decreasing or eliminating agrochemical concentration therein. Transforming agent activity is exhibited at spatially varying depths, at temporally varying times, within sub-surface geological matter.

Abstract translation: 农业基质（植物10，动物12）暴露于农用化学品（A）的方法; 降低或防止由于将农用基材暴露于农用化学品而导致的地下地质（20,22）污染的方法; 组合物[（A）/（T）] 30; 制品包括组合物。 包括将农业基质曝露于包括农业化学品的组合（混合物）和至少一种能够降低或消除接触次表面地质学（在时间上变化的时间和在空间上变化的深度）的农药的浓度的转化剂的组合物。 在进入地下地质事件之前，转化剂表现出不活跃的农药浓度降低，以及影响和/或干扰农用基料农药功能的不活动。 转化剂共同迁移，并与农用化学品共同分布在地下地质物质内部和整个地表，并表现出减少或消除其中农药浓度的活性。 转化剂活性在空间变化的深度，在时间上变化的时间，在地下地质物质内表现出来。
