1.0000 Elemental speciation in human health risk assessment (EHC 234, 2006)
    Summary: 1.3 Structural aspects of speciation The definitions of species and speciation of elements are based on several different levels of atomic and molecular structure where EHC 234: Elemental Speciation in Human Health Risk Assessment 2 species differences are manifest. Uptake systems are never entirely specific for a single element, and these systems often show competition between similar EHC 234: Elemental Speciation in Human Health Risk Assessment 4 chemical species of different elements, ...

1.0000 Manganese (EHC 17, 1981)
    Summary: 1.1.7 Effects on man Occupational exposure Chronic manganese poisoning is a hazard in the mining and processing of manganese ores, in the manganese alloy and dry-cell battery industries, and in welding. Many manganese chemicals, eg., potassium permanganate, manganese(II) sulfate, manganese dichloride, and manganese dioxide are used in fertilizers, animal feeds, pharmaceutical products, dyes, paint dryers, catalysts, wood preservatives and, in small quantities, in glass and ceramics.

1.0000 Manganese And Its Compounds:Environmental Aspects (Cicads 63, 2004)
    Summary: The manganese oxides (manganese dioxide and manganese tetroxide) are poorly soluble in water. Concentrations were determined in five different fractions for each sample: manganese in the exchangeable form, manganese bound to carbonates, manganese bound to manganese/iron oxides, manganese bound to organic matter, and manganese in the residual form. The most commonly occurring manganese-bearing minerals include pyrolusite (manganese dioxide), rhodocrosite (manganese carbonate [MnCO3]), ...

    Summary: a Manganese Manganous Manganese Manganese Manganese potassium chloride sulfate (II, III) oxide dioxide permanganate Synonyms Elemental Manganese Manganous Trimanganese Manganese Permanganic acid; manganese chlorideb; sulfate; tetroxide; peroxide; potassium saltc; colloidal manganese sulfuric acid mangano-manganic manganese chameleon material manganese; dichloride manganese

1.0000 Scientific Basis for Swedish Occupational Standards XVIII, Arbete och Hälsa vetenskaplig skriftserie 1997:25 (KemI-Riskline)
    Summary: In a teratogenicity study with rats, no maternal toxicity was observed after exposure to 100 ppm DEGEE 7 hours/day for 9 days, but the report contains no further details (37). Human data There are no reports on effects of occupational exposure. ________________________________________________________________________ 12.9 8 hours Mouse 7-alkylation of guanine in DNA 27 92 6 hours Rat Saturation of ethene metabolism 11 3450 28 days Mouse No increase in micronuclei 33 3450 2 years Rat No toxic ...

0.9947 Copper (EHC 200, 1998)
    Summary: Information on the physicochemical forms of copper (speciation) is more informative than total copper concentrations. The more soluble salts (copper(II) sulfate, copper(II) chloride) are generally more toxic than the less soluble salts (copper(II) hydroxide, copper(II) oxide). Although plants require copper as a trace element, at high soil levels copper can be extremely toxic.

0.9795 Nickel (EHC 108, 1991)
    Summary: Epidemiological studies Nickel refining industry Nickel alloy manufacturing Nickel plating industry Welding Nickel powder Nickel-cadmium battery manufacturing Case-control studies 9.5.2. (c) Nickel oxide Nickel oxide was present in almost all circumstances in which cancer risks were elevated, together with one or more other forms of nickel (nickel subsulfide, soluble nickel, metallic nickel).

0.9794 Maneb (IARC Summary & Evaluation, Volume 12, 1976)
    Summary: Maneb has been tested in mice and rats by oral administration and by single subcutaneous injection. Its oral administration produced an increased incidence of lung tumours in mice of one strain, but no increase was observed in three other strains. No evaluation of the carcinogenicity of this compound can be made.

0.9688 641. Prochloraz (Pesticide residues in food: 1983 evaluations)
    Summary: Total residues of both free and conjugated residues of prochloraz (BTS 40 542), N-formyl-N'-propyl-N'-2(2,4,6-trichlorophenoxy) ethylurea (BTS 44596), N-propyl-N-2 (2,4,6-trichlorophenoxy) ethylurea (BTS 44595) and 2,4,6-trichlorophenol (BTS 45186), hereafter referred to as total residues of prochloraz and metabolites, are listed in Table 2. The values (corrected for 90 percent recoveries) are expressed as prochloraz equivalents but were determined as 2,4,6-trichlorophenol after hydrolysis. ...

0.9615 Zinc (EHC 221, 2001)
    Summary: A WHO Task Group on Environmental Health Criteria for Zinc met in McLaren Vale, Australia, from 16 to 20 September 1996. Dr G.C. Becking, IPCS, opened the meeting and, on behalf of the Director, IPCS and the three cooperating organizations (UNEP/ILO/WHO), thanked the Australian Commonwealth and State Governments for their funding of the Task Group as well as their financial and in-kind support for the preparation of the first draft of the Environmental Health Criteria for Zinc. The Task Group...
