This evaluation was requested from Ministry of Health, Labour and Welfare (MHLW) to revise the standards for use of additives. Aluminium ammonium sulfate and aluminium potassium sulfate as additives are assumed reasonably to behave as ions after dissociation, such as aluminium, ammonium, potassium, and sulfate ions, in digestive tract prior to their absorption. FSCJ thus evaluated the safety of aluminium ammonium sulfate and aluminium potassium sulfate used as additives, in considering the substances that are composed of ammonium ion, sulfate ion, potassium ion and aluminium ion. FSCJ concluded that there were no safety concerns of sulfate, ammonium and potassium ions as the use of aluminium ammonium sulfate and aluminium potassium sulfate for food additives. FSCJ specified the lowest no-observed-adverse-effect level (NOAEL) of 30 mg/kg bw/day for aluminium ion based on the reproductive developmental toxicity studies in rats. FSCJ also recognized no carcinogenicity of aluminium additives. FSCJ judged no clear relationship of dietary intake of aluminium with the influences on the bone, mainly due to the insufficient amounts of evidence. FSCJ judged no sufficient evidence to indicate a causal relationship between dietary intake of aluminium and neurological diseases including Alzheimer's disease. FSCJ confirmed that no human data exist to indicate the clear association of the dietary intake with human health effects of aluminium. FSCJ specified this metal (Al) to be 1.0 mg/kg bw/week for the children (1 to 6 years) and 0.57 mg/kg bw/week for the general population. A safety factor of 100 was applied to the NOAEL of 30 mg/kg bw/day obtained in a developmental toxicity study in rats. Converting the value thus obtained to the aluminium intake per a week, FSCJ established a tolerable weekly intake (TWI) of 2.1 mg/kg bw/week (as Al) for aluminium.</p>","PeriodicalId":73044,"journal":{"name":"Food safety (Tokyo, Japan)","volume":"7 3","pages":"79-82"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.14252/foodsafetyfscj.D-19-00015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37592976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major toxicities induced by Cr (VI) were damages to small intestine and anemia in experimental animals. The finding observed at the lowest LOAEL was diffuse hyperplasia of mucosal epithelium in the duodenum in mice. Regarding to carcinogenicity, Cr (VI)-treatment by drinking water significantly increased incidences of tumors in the small intestine in mice and in the oral mucosa and tongue in rats. Therefore, FSCJ considered that Cr (VI) is carcinogenic. Cr (VI) showed positive results in many genotoxic studies <i>in vitro</i>, and <i>in vivo</i> after parenteral administration, whereas no clear positive results were obtained after the oral administration. These data indicate the genotoxic properties of Cr (VI), though genotoxicity by the oral administration including drinking water remains unclear. The mechanism of small intestinal tumors in mice is considered as follows: Continuous damage to mucosal epithelium in the small intestine by long-term exposure to Cr (VI) induces the hyperplasia in the crypt of small intestine, which would lead to the formation of tumor. In the <i>in vivo</i> gene mutation assays using transgenic rats and mice, no significant increases in mutant frequencies of the transgenes were observed in the carcinogenic target tissues, after exposure to Cr (VI) in drinking water for either 28 (rats) or 90 days (mice)<sup>1),</sup> <sup>2)</sup>. On the basis of these results, FSCJ judged that the carcinogenic mechanism of Cr (VI) intakes through drinking water was hardly attributable to the genotoxicity. FSCJ considered that the quantitative risk assessment of Cr (VI) through drinking water was difficult to conduct based on the results from epidemiological studies of non-occupational and occupational exposures in human population. Consequently, specifying a tolerable daily intake (TDI), based on the results of animal studies with oral exposure to Cr (VI) through drinking water, is rather feasible. FSCJ specified the TDI of Cr (VI) as 1.1 μg/kg bw/day after applying the uncertainty factor of 100 to BMDL<sub>10</sub> of 0.11 mg/kg bw/day, which was ascribed on the diffuse epithelial hyperplasia in the duodenum in male mice observed in the two-year oral exposure study. Since chromium in food is regarded to be present as trivalent chromium<sup>3)</sup>, FSCJ estimated daily intake of Cr (VI) from consumption of mineral water and tap water. The estimation gave the mean and high intakes as ca. 0.04 μg/kg bw/day and 0.290 μg/kg bw/day, respectively. Since both of these two values were lower than the TDI, 1.1 μg/kg bw/day, FSCJ concluded the risk of health effects from Cr (VI) at the current exposure through the consumption of mineral water and tap water to be extremely low.</p>","PeriodicalId":73044,"journal":{"name":"Food safety (Tokyo, Japan)","volume":"7 2","pages":"56-57"},"PeriodicalIF":0.0,"publicationDate":"2019-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.14252/foodsafetyfscj.D-1900002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37593948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
