0.7742 FLUORIDES (EHC 227, 2002)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc227.htm
    Summary: Data on hydrogen fluoride, calcium fluoride, sodium fluoride, sulfur hexafluoride and silicofluorides are covered, as these compounds are considered to be the most relevant of the inorganic fluorides on the basis of quantities released to the environment, environmental concentrations and toxicological effects on living organisms. Sodium fluoride (NaF) is a colourless to white solid that is moderately soluble in water. The most common procedure used to quantify free fluoride anion is the ...

0.7742 Barium (EHC 107, 1990)
    10-09-18, http://www.inchem.org/documents/ehc/ehc/ehc107.htm
    Summary: In nature barium occurs only in a combined state, the principal mineral forms being barite (barium sulfate) and witherite (barium carbonate). With the exception of barium sulfate, the water solubility of the barium salts increases with decreasing pH. The two most prevalent naturally occurring compounds of barium are barite (barium sulfate) and witherite (barium carbonate).

0.7742 Chlorobenzenes Other Than Hexachlorobenzene: Environmental Aspects (Cicads 60, 2004)
    10-09-18, http://www.inchem.org/documents/cicads/cicads/cicad60.htm
    Summary: Concentrations of chlorobenzenes (MCB, dichlorobenzenes, and trichlorobenzenes) have been reported in ambient air, with mean concentrations in the order of 0.1 µg/m3 and maximum levels (at hazardous waste sites) of up to 100 µg/m3. Concentrations of chlorobenzenes in surface waters are generally in the ng/litre to µg/litre range, with maximum concentrations up to 0.2 mg/litre in areas close to industrial sources. Chronic no-observed-effect concentrations (NOECs) for freshwater invertebrates ...

0.7742 Thiourea (CICADS 49, 2003)
    10-09-18, http://www.inchem.org/documents/cicads/cicads/cicad49.htm
    Summary: Tolerable intakes should be much below 0.07 mg thiourea/kg body weight per day. From data on its use as a thyroid depressant, <15 mg thiourea/day (<0.2 mg/kg body weight per day) had no effect, whereas 70 mg/day (about 1.0 mg/kg body weight per day) showed an effect. In the USA, thiourea is used in animal hide glue, which contains thiourea at a concentration of 10-20% as a liquefying agent.

0.7742 Scientific Basis for Swedish Occupational Standards XXVII, NR 2006:11 (KemI-Riskline)
    04-02-08, http://www.inchem.org/documents/kemi/kemi/ah2006_11.pdf
    Summary: In the subjects accustomed to exposure, a significant increase of irritation symptoms was reported only at 50 ppm and there was no significant increase of respiratory symptoms at any exposure level. In persons unaccustomed to exposure, both irritation symptoms and respiratory symptoms increased significantly with increasing exposure, but the exposure levels at which the increases became significant (besides 50 ppm) is not clear. At 50 ppm, persons accustomed to exposure reported significantly...

0.7742 Scientific Basis for Swedish Occupational Standards XXVI, NR 2005:17 (KemI-Riskline)
    04-02-08, http://www.inchem.org/documents/kemi/kemi/ah2005_17.pdf
    Summary: With exposure to hydrogen fluoride from hydrofluoric acid baths, urine fluoride level rose by 4.6 mg/l when fluoride in air rose by 1 mg/m 3 (63). For welding with basic electrodes containing calcium fluoride, urine fluoride level rose by 1.5 mg/l when fluoride in air rose by 1 mg/m 3 (137). In Germany there are biological exposure limits for urine content of fluorides as indicators of exposure to hydrogen fluoride and inorganic fluorides. Table 3 (skin exposure), Table 4 (inhalation exposure...

0.7742 Scientific Basis for Swedish Occupational Standards XXIV, NR 2003:16 (KemI-Riskline)
    04-02-08, http://www.inchem.org/documents/kemi/kemi/ah2003_16.pdf
    Summary: Human studies - controlled exposure Effects of diesel exhaust The cellular and biochemical effects on respiratory passages of short-term exposure to diesel exhaust have been studied in exposure experiments. A compilation of the conclusions in surveys of a connection between lung cancer and exposure to diesel exhaust is given in Table 3. Table 3. Assessments of relationships between exposure to diesel exhaust and lung cancer given in meta-analyses and surveys of epidemiological studies. In ...

0.7742 The Nordic Expert Group for Criteria documentation of Health Risks from Chemicals and The Dutch Expert Committee on Occupational Standards, NR 2003:14 (KemI-Riskline)
    04-02-08, http://www.inchem.org/documents/kemi/kemi/ah2003_14.pdf
    Summary: Exposure lasted 3.5 hours and concentrations in exhaled air were followed up to 50 hours after termination of exposure. However, these studies do not allow for more quantitative conclusions, because data on exposure or concentrations in biological samples were too incomplete and simultaneous respiratory and dermal exposure and absorption may have contri- buted to effects or concentrations in biological samples. (257) show that upon repeated exposure (101 ppm (696 mg/m 3 ); periods of 7 hours ...
