Abrégé
A multifunctional formed object containing an adsorbent for hazardous substances is provided in the form of a water-soluble sheet or tablet. The formed object comprises a hazardous-substance-adsorbing formed object having a multiple function imparted thereto, and can be applied to a contaminated environment while preventing a fine powder from flying off or causing dust explosion and without necessitating much labor. After application, the formed object adsorptively fixes thereto a hazardous substance present in the contaminated environment. The hazardous-substance-adsorbing formed object, to which a hazardous substance is adsorptively fixed in a contaminated environment, e.g., a soil, is produced from a plurality of raw-material ingredients, one of which is a powdery adsorbent for hazardous substances. The adsorbent is a porous fine powder which includes particles each having a diameter capable of passing through 200-mesh and a particle density of an average particle size of 100 µm or smaller, the proportion of the particles being more than 80% of the weight of the powder. Besides the adsorbent, an additive for imparting another function is suitably incorporated.
