| 건강 유해성 | Excerpt from NIOSH Pocket Guide for Trimellitic anhydride: |
| 유해성 요약 | There are three syndromes caused by trimellitic anhydride (TMA) based on its ability to irritate and sensitize lung tissue. Sensitized workers can develop upon re-exposure 1) asthma-rhinitis2) late respiratory systemic syndrome (LRSS)or very rarely 3) pulmonary disease anemia syndrome (PDA). [Grammer LC et al. Review of trimellitic anhydride (TMA) induced respiratory response. Allergy Asthma Proc 1997 Jul-Aug18(4):235-7] Workers exposed to less than 0.002 mg/m3 are at low risk for developing disease. [Grammer LC et al. A Clinical and Immunologic Study to Assess Risk of TMA-Induced Lung Disease as Related to Exposure. JOEM 1999 Dec41(12):1048-51] TMAN is a potent sensitizer after inhalation of either dust or fume. It causes IgE and IgG mediated disease (asthma/rhinitis, late respiratory systemic syndrome, pulmonary disease anemia, and late arthralgia myalgia). Symptoms include sneezing, rhinitis, dry throat, watery eyes, conjunctivitis, and dyspnea. Dermal contact may cause or exacerbate respiratory sensitization. When workers are not exposed to >2 ug/m3, there are no cases of disease or IgG against TM-HAS (Human Serum Albumin), but there are still cases of non-diseased workers with IgE against TM-HAS (9% incidence). TMAN cause both immediate and delayed dermal sensitization in animal studies. [ACGIH] Danger of airway sensitization[MAK] TMA skin testing provides an alternative and potentially more practical method for monitoring TMA-exposed workers for developing IgE sensitization.

| 체내 부담 | Personal breathing zone samples from two workers in a 55-gallon drum manufacturing plant had an 8 hour exposure to trimellitic anhydride of 3.6 mg/cu-m and 1.7 mg/cu-m(1). |
| 상호 작용 | ... Ozone (3 ppm for 3 hr) caused an increase in -log PC300 at 1 hr after exposure, with return of -log PC300 to control levels at 8 hr. Ozone also increased baseline RL at 8 hr. trimellitic anhydride (TMA) challenge increase -log PC300 in TMA-sensitized guinea pigs at 8 hr after challenge from 3.85 +/- 0.09 to 4.11 +/- 0.09. Ozone exposure prior to TMA challenge prevented the induction of airway hyperresponsiveness with a mean -log PC300 of 3.51 +/- 0.20, which was not different from that of control TMA-sensitized group. Baseline lung resistance was significantly higher in ozone-pretreated animals after TMA challenge when compared to those of either control or challenged with TMA alone. Ozone had no effect on TMA challenge-induced BAL eosinophilia and neutrophilia.... Before challenge, sensitized animals were pretreated iv with inhibitors of different mediators: pyrilamine (antihistamine: 2 mg/kg, indomethacin (cyclooxygenase inhibitor: 10 mg/kg), OKY-046 (thromboxane synthetase inhibitor: 30 mg/kg), ICI-198,615 (leukotriene receptor antagonist: 10-6 mol/kg), ketanserin (5-HT2 receptor antagonist: 1 mg/kg), or azelastine ("antiallergic agent": 1 mg/kg). Intratracheal instillation of trimellitic anhydride conjugated to guinea pig serum albumin (TMA-GPSA) induced a slowly progressing increase in lung resistance (RL) and produced extravasation of Evans blue dye at all airway levels in sensitized animals. Pyrilamine and azelastine abolished the increase in RL induced by TMA-GPSA until 2.5 min after the challenge. Indomethacin and OKY-046 significantly attenuated the increase in RL 3 min after the challenge. ICI-198,615 and ketanserin did not significantly affect the increase in RL. Extravasation of Evans blue dye induced by TMA-GPSA was decreased by pyrilamine, azelastine and ICI-198,615 in main bronchi and intrapulmonary airways. Indomethacin, OKY-046 and ketanserin did not significantly affect the extravasation of dye into the airway tissue.... Both IgE and IgG anti-trimellitic anhydride antibodies started to rise between weeks 1 and 3 after immunisation, reached their highest levels 7 weeks after sensitisation with 3% of TMA and then started to decline. Betamethasone and cyclosporin A (CsA) given orally over the time of sensitisation (8 days in total) inhibited the development of specific IgE and IgG anti-TMA antibodies. Betamethasone given 10-17 days after sensitisation attenuated the IgE and IgG antibody responses as well while treatment with CsA after sensitisation had no effect on the production of specific antibodies. Levels of total IgE and IgG were not affected except for a small decrease in total IgE using medium-dose betamethasone after sensitisation.... Guinea pigs pretreated with cobra venom factor (CVF) had significantly reduced amounts of complement component C3 in the lavage fluid 24 hours after trimellitic anhydride (TMA) conjugated to guinea pig serum albumin challenge. Pretreatment with CVF did not affect the immediate TMA-induced bronchoconstriction nor the TMA-induced microvascular leakage. In animals depleted of the complement system by pretreatment with CVF the TMA-induced increase in mononuclear cells, total white blood cells, red blood cells, and EPO activity in the bronchoalveolar lavage was significantly reduced.... Exposure to 0.5 mg/cu m trimellitic anhydride produced hemorrhagic foci of the lung and increased antibody levels in rats treated for six hours/day, five days/week for two weeks ... Estrogen treatment reduced the number of lung foci in both male and female rats, while testosterone treatment had no effect. |

| 환경 거동 | TERRESTRIAL FATE: Based on the structural similarities to phthalic anhydride, trimellitic anhydride is expected to have a similar hydrolysis rate(SRC). Phthalic anhydride has been reported to hydrolyze rapidly in water(1) and estimated half-lives of approximately 1.5 minutes and 2.7 minutes were calculated(SRC) using reported observed rate constants of 7.9X10-3/sec(2) and 4.3X10-3/sec(3), respectively. Based upon this hydrolysis rate, trimellitic anhydride is expected to hydrolyze in moist soils(SRC).

Therefore, volatilization from water surfaces, adsorption to suspended solids and sediments, biodegradation, and bioconcentration of trimellitic anhydride are not expected to be important in aquatic systems based on hydrolysis(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), trimellitic anhydride, which has an extrapolated vapor pressure of 9.86X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase trimellitic anhydride is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 20 days(SRC), calculated from its rate constant of 7.97X10-13 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase trimellitic anhydride may be physically removed from the air by wet and dry deposition(SRC). |

| Medical Surveillance | This article described our clinical and immunologic experience in assessing workers exposed to trimellitic anhydride (TMA) in three industrial settings. Since 1977 /the authors/ have had engaged in a prospective study of workers involved at the site of manufacture of TMA. These studies demonstrate that serologic measurements of total antibody to trimellityl human serum albumin (TM-HSA) and IgE antibody to TM-HSA are predictive of the development of an immunologically mediated respiratory illness and are useful in monitoring workers removed from TMA exposure, in identifying asymptomatic workers who may be at risk in the future, and in defining the nature of sensitization of the work force. In a different industrial setting, /the authors/ have been able to study workers who mixed previously manufactured TMA powder with epoxy resins. This study indicated that clinical assessments by a plant physician with a standardized questionnaire, along with serologic tests, could establish the presence or absence of an immunologic respiratory illness caused by the inhalation of TMA dust. In a third industrial situation, workers were exposed to both TMA and phthalic anhydride (PA). Here workers were interviewed by a local physician with minimal experience with TMA-related respiratory illness. In this situation a more detailed questionnaire was utilized, along with serologic tests utilizing the enzyme-linked immunosorbent assay to establish the presence of a TMA- or PA-related syndrome. Immunologic studies demonstrated in workers exposed to both TMA and PA that the antibody responses elicited showed little crossreactivity between antibodies directed against TM-HSA or PA-HSA.... A practical approach that has significantly reduced the incidence of immune disease due to trimellitic anhydride is periodic surveillance of exposed worker populations with serum antibody studies and questionnaires. Workers who have significant levels of antibody, report significant symptoms on questionnaires, or both, are further evaluated to determine the clinical diagnosis and whether any interventions are needed. |
