“…Shenbar and Johanson (53) found that 137 Cs in soils was not taken up by plants after treating the soil with a zeolite, and Forberg et al (54) showed that a zeolite supplement to the diets of Swedish reindeer accelerated the excretion of 137 Cs ingested with food contaminated by Chernobyl fallout. Zeolites added to soils reduced the uptake of 137 Cs by pasture plants in the vicinity of Chernobyl (55), and dietary zeolite reduced sorption of radiocesium by sheep fed fallout-contaminated rations in Scotland (56). In Bulgaria, zeolite pills and cookies were prepared for human consumption to counteract Chernobyl fallout (57).…”

For nearly 200 years since their discovery in 1756, geologists considered the zeolite minerals to occur as fairly large crystals in the vugs and cavities of basalts and other traprock formations. Here, they were prized by mineral collectors, but their small abundance and polymineralic nature defied commercial exploitation. As the synthetic zeolite (molecular sieve) business began to take hold in the late 1950s, huge beds of zeolite-rich sediments, formed by the alteration of volcanic ash (glass) in lake and marine waters, were discovered in the western United States and elsewhere in the world. These beds were found to contain as much as 95% of a single zeolite; they were generally f lat-lying and easily mined by surface methods. The properties of these low-cost natural materials mimicked those of many of their synthetic counterparts, and considerable effort has made since that time to develop applications for them based on their unique adsorption, cation-exchange, dehydration-rehydration, and catalytic properties. Natural zeolites (i.e., those found in volcanogenic sedimentary rocks) have been and are being used as building stone, as lightweight aggregate and pozzolans in cements and concretes, as filler in paper, in the take-up of Cs and Sr from nuclear waste and fallout, as soil amendments in agronomy and horticulture, in the removal of ammonia from municipal, industrial, and agricultural waste and drinking waters, as energy exchangers in solar refrigerators, as dietary supplements in animal diets, as consumer deodorizers, in pet litters, in taking up ammonia from animal manures, and as ammonia filters in kidney-dialysis units. From their use in construction during Roman times, to their role as hydroponic (zeoponic) substrate for growing plants on space missions, to their recent success in the healing of cuts and wounds, natural zeolites are now considered to be full-f ledged mineral commodities, the use of which promise to expand even more in the future.The discovery of natural zeolites 40 years ago as large, widespread, mineable, near-monomineralic deposits in tuffaceous sedimentary rocks in the western United States and other countries opened another chapter in the book of useful industrial minerals whose exciting surface and structural properties have been exploited in industrial, agricultural, environmental, and biological technology. Like talc, diatomite, wollastonite, chrysotile, vermiculite, and bentonite, zeolite minerals possess attractive adsorption, cation-exchange, dehydration-rehydration, and catalysis properties, which contribute directly to their use in pozzolanic cement; as lightweight aggregates; in the drying of acid-gases; in the separation of oxygen from air; in the removal of NH 3 from drinking water and municipal wastewater; in the extraction of Cs and Sr from nuclear wastes and the mitigation of radioactive fallout; as dietary supplements to improve animal production; as soil amendments to improve cation-exchange capacities (CEC) and water sorption capacities; as soilless zeopon...

“…Different materials have been administered to ruminants for reducing radiocaesium transfer to meat and milk products. These include bentonite (Andersson 1989, Mitchell et al 1989, zeolite (Phillippo et al 1988, vermiculite (Hazzard 1969), kaolin (Giese 1989), stable caesium (Oughton et al 1991) and crude fibre (Johnson et al 1968). Organic complexes such as ferric hexacyanoferrates, commonly referred to as Prussian Blue (PB) compounds are, however, the most effective caesium binders on a unit weight basis (Giese 1989.…”

A study was carried out to examine the effect of ammonium ferric hexacyanoferrate (AFCF) on the transfer of radiocaesium from grass silage to the tissues of male lambs. During ensiling, a formic acid based additive and AFCF were sprayed on grass contaminated with 134Cs and the mixture was allowed to incubate for 45 days. A dose of 21 mg AFCF d-1, fed to sheep offered contaminated silage for fourteen days, reduced 134Cs transfer to muscle by 45% compared to that of control sheep. An equivalent dose of AFCF administered in a capsule reduced transfer by only 3%. In another experiment, AFCF intake of 50, 100 and 150 mg d-1 for ten days reduced 134Cs transfer to sheep muscle by 75, 82 and 86%, respectively. In control lambs, of average live weight 38 and 47 kg, the feed to muscle 134Cs transfer coefficient averaged 0.15 d kg-1, but equilibrium between tissue and feed 134Cs had probably not been reached due to the short feeding period. Increasing doses of AFCF from 0 to 150 mg d-1 increased the faecal/urinary 134Cs ratio from 2 to 42.;

“…The effects of clay minerals and AFCF in reducing the radiocesium concentration in different animals are well documented (Mirna 1970;Andersson et al 1990;Pethes et al 1988;Phillippo et al 1988;Jandl and Novosad 1995;Giese 1988;Voigt et al 1993;Howard et al 2001;Vitorović et al 2002;Mitrović et al 2007). As a cesium protector, AFCF exerted the best binding effects.…”

“…Natural zeolite-clinoptilolite, as one of the most important natural ion exchangers, has also been used for adsorption of radiocesium in rabbits (Pethes et al 1988) and sheep (Phillippo et al 1988;Jandl and Novosad 1995). Pöschl and Baláš (1999) proved that modified clinoptilolite (RADEKONT-natural clinoptilolite modified with hexacyanoferrate) significantly decreased the uptake of 137 Cs in broilers chicken meat after single or repeated administration of contaminated feed.…”

The aim of the present study was to investigate distribution of (137)Cs in leg and breast meat of broilers and pheasants following single alimentary contamination and administration of two protectors (AFCF and clinoptilolite). The birds were administered a single dose of (137)CsCl, with an activity of 750 Bq. Protectors were given via gastric tube or mixed in the forage pellets. AFCF given via gastric tube decreased the (137)Cs concentration by a factor of 7.8 in broilers leg meat and 7.4 in broilers breast meat. When AFCF was mixed in pellets, the (137)Cs concentration was 19.5 times lower in broilers leg meat and 22.1 times lower in broilers breast meat, than in the control group. In pheasants, AFCF administered via gastric tube decreased the (137)Cs concentration by a factor of 12.4 in leg meat and by a factor of 13.7 in breast meat, respectively. In group 4, where pheasants were administered AFCF mixed in pellets, the (137)Cs concentration was 3.7 times lower in leg and breast meat, than in the control group. For comparison, clinoptilolite administered via gastric tube decreased the (137)Cs concentration 1.8 times in broilers leg meat and 2.0 times in breast meat, compared to the control group. In pheasants, (137)Cs concentration was 2.9 times lower in leg meat and 2.6 times lower in breast meat. Clinoptilolite mixed in the feed had relatively low efficiency of protection in broilers ((137)Cs concentration was 1.4 times lower in leg meat and 1.6 lower in breast meat). A similar trend was observed in pheasants ((137)Cs concentration was 1.6 lower in leg and breast meat).
