0.8909 866. Maneb (Pesticide residues in food: 1993 evaluations Part II Toxicology)
    10-09-18, http://www.inchem.org/documents/jmpr/jmpmono/v93pr12.htm
    Summary: During weeks 1-4, residue levels in lungs for males ranged between 3.9-7.9 ppm (7.9-6.8 ppm for weeks 2 and 4) for maneb; 4.8-6.0 ppm for manganese and 0.12-0.19 ppm for ETU; for females 2.1-4.2 ppm for maneb, 1.8-2.8 for manganese and < 0.1-0.12 ppm for ETU. The NOAEL was 200 ppm, equal to 6.4 mg/kg bw/day for males and 7.2 mg/kg bw/day for females, based on thyroid enlargement and thickening and thyroid follicular cell hyperplasia at 1000 ppm (Corney et al., 1992).

0.8792 Toluidine,o- (Screening Information Data Set - SIDs)
    12-14-06, http://www.inchem.org/documents/sids/sids/95534.pdf
    Summary: In in-vitro tests for chromosomal aberrations o-toluidine yielded positive results in several cell systems and did induce micronuclei in human lymphocytes in-vitro. As results from further testing would not affect the most stringent exposure control measures being already in place due to genotoxicity and carcinogenicity of o-toluidine, no further tests are warranted. The test design is comparable to the Zahn-Wellens-test (OECD TG 302 B). The test substance o-toluidine in a concentration of ...

0.8792 IPCS Risk Assessment terminology (Harmonization Project Publications)
    02-19-08, http://www.inchem.org/documents/harmproj/harmproj/harmproj1.pdf
    Summary: The risk assessment process includes four steps: hazard identification, hazard characterization (related term: Dose-response assessment), exposure assessment, and risk characterization. The following terms were cited as synonyms: dose-response, effect assessment, effects assessment, toxicity assessment, dose-effect assessment, effects characterization, dose- response evaluation, dose-response estimation, toxicity test, and bioassay. A number of synonyms were mentioned: risk estimation, ...

0.8792 Thallium (EHC 182, 1996)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc182.htm
    Summary: Plants 9.3.1.1 Plant photosynthesis 9.3.1.2 Cytotoxic effects 9.3.1.3 Growth of plants 9.3.1.4 Different sensitivities to thallium(I) and thallium (III) 9.3.1.5 Concentration of trace elements 9.3.1.6 Sensitivity of plants 9.3.2. Thallium has two important oxidation states, thallium(I) and thallium(III). The most recent (1980s) concentrations of thallium observed were < 22 µg thallium/m3 (in the production of a special thallium alloy and in a thallium smelter).

0.8792 Chromium (EHC 61, 1988)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc61.htm
    Summary: Reduction of chromium (VI) within the cell nucleus and the formation of chromium (III) complexes suggests that chromium (III) would be the ultimate mutagenic form of chromium. Chronic effects of exposure to chromium (excessive industrial exposure of the skin to hexavalent chromium, when associated with damaged skin or inhalation of airborne chromium (VI) or mixed dust) occur in the lung, liver, kidney, gastrointestinal tract, and ciculatory system. Sodium and potassium dichromates are widely ...
