0.7742 Nitrobenzene (EHC 230, 2003)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc230.htm
    Summary: Since its inauguration the EHC Programme has widened its scope, and the importance of environmental effects, in addition to health effects, has been increasingly emphasized in the total evaluation of chemicals. A WHO Task Group on Environmental Health Criteria for Nitrobenzene met at the Fraunhofer Institute of Toxicology and Experimental Medicine, Hanover, Germany, from 19 to 23 February 2001. The Task Group reviewed and revised the draft monograph and made an evaluation of the risks for ...

0.7742 Toxicokinetic studies, principles of (EHC 57, 1986)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc57.htm
    Summary: In vivo methods 3.3.2.1 Methods for the pulmonary exposure of intact animals 3.3.2.2 Methods for the pulmonary exposure of anaesthetized animals 3.3.3. Finally, selected biological, chemical, or physical methods must be used to identify the toxic chemical unambiguously and to determine the exact amount present in the sample. If a bioassay is used, the organisms used in the assay should ideally respond only to the test chemical, or to a limited number of other chemicals that can be shown not ...

0.7742 Guidance values for human exposure limits (EHC 170, 1994)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc170.htm
    Summary: 2.3 Interpretation and use of guidance values Media exposure allocations of TIs for the derivation of guidance values in EHC monographs are based on relative exposure by different routes for a given scenario. 3. Development of guidance values from intake assigned to each medium, taking into account, for instance, body weight, volume of intake and (relative) absorption efficiency ( relative where guidance value is derived on the basis of a TI by another route of exposure). Use TI for principal...

0.7742 Butanols - four isomers (EHC 65, 1987)

0.7742 Morpholine (EHC 179, 1996)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc179.htm
    Summary: Based on the available data, the main source of general population exposure to morpholine is food, which can be contaminated with morpholine through direct treatment of fruit with waxes containing morpholine for conservation purposes, through steam treatment during food processing, and by the use of packaging material containing morpholine. (1990) also used an isotachophoretic method for determining morpholine in rubber samples (see Table 2). 2.4.2 Determination of morpholine in water The ...

0.7742 Biomarkers and risk assessment: concepts and principles (EHC 155, 1993)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc155.htm
    Summary: 1.3 Biomarkers and the risk assessment process For a general discussion of concepts and principles underlying assessment of risk to human health associated with exposure to chemicals, the reader is referred to WHO (in press). The relevance of biomarkers to the phases of the risk assessment process is discussed more fully in later sections that address biomarkers of effects, exposure and susceptibility. 5. BIOMARKERS OF EXPOSURE The exposure assessment component of the risk assessment process ...

0.7742 Fluorine and fluorides (EHC 36, 1984)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc36.htm
    Summary: Compounds dealt with in this document, besides fluorine, include hydrogen fluoride, alkali fluorides, fluorspar, cryolite, fluoroapatite, other inorganic fluoride compounds, and certain organic fluorides that release fluoride when metabolized. Sodium fluoride and other alkali fluorides The alkali fluorides are typical salts. For instance, gaseous fluoride compounds such as hydrogen fluoride and silicon tetrafluoride are more toxic to vegetation than most particulate fluoride compounds (Less ...

0.7742 Man-made mineral fibres (EHC 77, 1988)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc77.htm
    Summary: Identity, Terminology, Physical and Chemical Properties, Analytical Methods Man-made mineral fibres (MMMF), most of which are referred to as man-made vitreous fibres (MMVF), are amorphous silicates manufactured from glass, rock, or other minerals, which can be classified into four broad groups: continuous filament, insulation wool (including rock/slag wool, and glass wool), refractory (including ceramic fibre), and special purpose fibres. Nominal fibre diameters for these groups are 6 - 15 ┬Ám...

0.7742 Inorganic lead (EHC 165, 1995)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc165.htm
    Summary: Environmental Health Criteria 3: Lead, published in 1977, examined the effects of lead on human health and Environmental Health Criteria 85: Lead - Environmental Aspects was published in 1989. The level of dietary exposure to lead depends upon many lifestyle factors, including foodstuffs consumed, processing technology, use of lead solder, lead levels in water, and use of lead-glazed ceramics. Blood lead (PbB) levels are used as a measure of body burden and absorbed (internal) doses of lead.
