Abstract: Construction for absorbing a fluid, for example, a liquid or gaseous, organic chemical, has an extended web, fabric, yarn or foam member and associated with the extended web, fabric, yarn or foam member is a water-insoluble polymer. The water-insoluble polymer can absorb the fluid organic chemical, and the construction provides for contact of the water-insoluble polymer with the fluid organic chemical when deployed in an environment where the fluid organic chemical may be present for absorption. The construction may be employed in aquatic, aqueous, or dry environments, as a blotter, a wipe or sponge, a filter, in a cartridge, and so forth.

Abstract: Composition has an indicating dye encapsulated by an encapsulating material. An encapsulated indicating dye can be combined with an organic substance absorbent and/or adsorbent. The composition, combination and/or a device having one or both of them can be used to indicate the presence of an organic substance by contacting the same with a sample, and, ascertaining whether an appropriate color release occurs to indicate the presence of the organic substance by contact of the organic substance with the composition, combination and/or device.
