    Summary: Oral studies in rats and mice resulted in LD50 values in the range 10-160 mg/kg body weight for vanadium pentox ide and other pentavalent vanadium compounds, while tetravalent vanadium compounds have LD50 values in the range 448-467 mg/kg body weight. This method can be used for measuring vanadium and vanadium compounds in workplace air, but no method performance data are available for vanadium. The most frequently used vanadium pentoxide catalyst contains 4-6% vanadium as vanadium pentoxide ...

0.7967 DECOS and NEG Basis for an Occupational Standard, 1997:14 (KemI-Riskline)
    Summary: The divalent compounds are predominantly four-coordinate and square planar, the tetravalent compounds six-coordinate and octahedral and the zerovalent compounds four-coordinate and tetrahedral (22, 46).

0.7961 Tetraethylenepentamine (Screening Information Data Set - SIDs)
    Summary: The results of a 28-day repeated dose dermal toxicity study of TEPA indicated a systemic toxicity NOEL of 200 mg/kg/day and a dermal toxicity NOEL (local) of 50 mg/kg/day. OECD SIDS TETRAETHYLENEPENTAMINE UNEP Publications 9 2. GENERAL INFORMATION ON EXPOSURE TEPA does not occur naturally. 3.1.3 Repeated Dose Toxicity Dermal: TEPA was administered to rabbits at doses of 5 0, 100 or 200 mg/kg/day for 6 hours/day, 5 days/week for 4 weeks.

    Summary: In studies in which 59FeSO4 and 55Fe-glycinate (55Fe-Ferrochel® ferrous glycinate) were administered together in a whole-maize or wheat-flour meal (Allen et al., 1998; Bovell-Benjamin et al., 2000; Layrisse et al., 2000), significantly more iron was absorbed from ferrous glycinate (or Ferrochel® ferrous glycinate) than from FeSO4. There was no exchange of radiolabelled iron (i.e. 59Fe and 55Fe) between ferrous glycinate (or Ferrochel® ferrous glycinate) and FeSO4 in the non-haem ...

0.7961 551. Copper (WHO Food Additives Series 17)
    Summary: Daily food intake was less as dietary copper increased, with average copper intakes being 5, 8, 11 and 8 mg/rat/day, respectively. It was concluded that 1600 ppm (0.16%) copper either as copper sulfate or copper gluconate was toxic while 530 ppm (0.053%) copper as the sulfate caused only variable effects on testicular degeneration and tissue storage of copper (Harrison et al., 1954). Elevated blood copper levels occurred immediately before or during the haemolytic crisis and both plasma ...

0.7961 4-Methylpentan-2-ol (Methyl Isobutyl Carbinol) (Screening Information Data Set - SIDs)
    Summary: The results indicated that metabolism and clearance of MIBC is rapid through MIBK to HMP concluding that dosing with MIBC or MIBK results in similar internal exposure to MIBK and HMP and minimal exposure to MIBC. Therefore, the internal exposure to MIBC is minimal following MIBC dosing, and oral dosing of MIBC or MIBK results in similar internal exposure to MIBK and HMP. OECD SIDS 4-METHYLPENTAN-2-OL UNEP PUBLICATIONS 16 Inhalation A 6-week inhalation toxicity study with MIBC (Reliability = 2...

0.7961 Pyrrolizidine alkaloids (EHC 80, 1988)
    Summary: CONTENTS ENVIRONMENTAL HEALTH CRITERIA FOR PYRROLIZIDINE ALKALOIDS PREFACE INTRODUCTION - PYRROLIZIDINE ALKALOIDS AND HUMAN HEALTH 1. SUMMARY AND RECOMMENDATIONS 1.1. INTRODUCTION - PYRROLIZIDINE ALKALOIDS AND HUMAN HEALTH Pyrrolizidine alkaloids (PAs) are found in plants growing in most environments and all parts of the world. 6. Study is required of the possible alkaloid content of the meat, organs, and fat of animals that have recently consumed plants containing pyrrolizidine alkaloids.
