“…The chromium utilization in basal diet was very low (4.22%); this is consistent with previous reports showing that chromium absorption of corn‐soy‐based diet is less than 5% (Anderson and Kozlovsky, ). An in vitro study reported the chromium availability to be around 0.48–3.26% (Mateos et al., ) and 4.6% (Carlos et al., ) in cereals basal diet.Chromium utilization was increased by nanoparticle preparation; this finding is consistent with the previous report that rats receiving nanoparticle CrPic (300 μ g/kg) showed increased Cr digestibility and significantly increased serum Cr level, as compared with those receiving CrPic (Lien et al., ).

“…Some studies have reported that dietary CrPic supplementation at 200–400 μ g/kg levels leads to increased muscle mass in the longissimus muscle area and decreased back fat thickness in pigs (Page et al., ; Lien et al., ). Currently, chromium is being applied in dietary supplements in animals; however, the absorption of chromium is very low (Anderson and Kozlovsky, ; Carlos et al., ; Mateos et al., ). Thus, it is worth developing a more highly digestible form of chromium.…”

The aim of this study was to investigate the effect of dietary supplementation of nanoparticle trivalent chromium on nutrient utilization, growth performance and serum traits of broilers. This study included two trials. In trial 1, 32 three-week-old broilers were divided into four groups: the control, chromium chloride (CrCl3), chromium picolinate (CrPic) and nanoparticle chromium picolinate (NanoCrPic). Chromium was added at a 1200 μg/kg level to evaluate the nutrient and chromium utilization. In trial 2, 160 one-day-old broilers were randomly divided into four groups as in trial 1, with four replicates. The results of trial 1 indicated that the chromium utilization is as follows: NanoCrPic > CrPic > CrCl3 and control groups, with significant differences between groups (p < 0.05). Crude fat utilization in CrCl3 group was lower than in that the control group (p < 0.05). The results of trial 2 indicated that feed intake of 4-5 weeks showed better result in the CrCl3 group than that in the CrPic group (p < 0.05). The results of serum traits indicated that the LDL-cholesterol in the NanoCrPic groups was lower than that in the CrPic group (p < 0.05). The NanoCrpic and CrPic groups showed significantly increased serum chromium concentration when compared with the control and CrCl3 groups; the triglyceride level in the CrCl3 group was lower than that in the CrPic group (p < 0.05). This study concluded that compared with CrPic, NanoCrpic supplementation could increase chromium utilization and lower the serum LDL-cholesterol of broilers.

“…We note that the bread in the present study (in the interest of simplicity) did not contain oil, mixed salts (other than NaCl), milk powder, malt extract or sugar, all of which were present in the bread used in the Ivankovic and Preussman study (1975), but these ingredients (lipids, ions, protein and simple sugars) are not likely to increase the bioaccessibility. Instead they would likely decrease the bioaccessibility, since the presence of simple sugars reduces chromium absorption into tissues compared with starches (Seaborn and Stoecker 1989), lipids are inversely proportional with bioaccessible chromium in food (Mateos et al 2008), and other components like protein and minerals did not have a significant effect (ibid. ).…”

Bioaccessibility measurements have the potential to improve the accuracy of risk assessments and reduce the potential costs of remediation when they reveal that the solubility of chemicals in a matrix (e.g., soil) differs markedly from that in the critical toxicity study (i.e., the key study from which a toxicological or toxicity reference value is derived). We aimed to apply this approach to a brownfield site contaminated with chromium, and found that the speciation was Cr III , using a combination of alkaline digestion/diphenylcarbazide complexation and X-ray absorption near edge structure analysis. The bioaccessibility of Cr 2 O 3 , the compound on which a reference dose for Cr III is based, was substantially lower (<0.1%) than that of the Cr III in the soils, which was a maximum of 9%, giving relative bioaccessibility values of 13,000% in soil. This shows that the reference dose is based on essentially an insoluble compound, and thus we suggest that other compounds be considered for toxicity testing and derivation of reference dose. Two possibilities are CrCl 3 ·6H 2 O and KCr(SO 4 ) 2 ·12H 2 O, which have been used for derivation of ecological toxicity reference values and are soluble at a range of dosing levels in our bioaccessibility tests.
