Residents adjoining a die-casting plant had excessive headaches, numbness of hands and feet, dizziness, blurred vision, staggering, sweating, abnormal heart rhythm, and depression, which led to measurements of neurobehavioral performance, affective status, and the frequency of symptoms. They had all been exposed via well water and proximity to the plant to volatile organic chemicals (VOC) and to polychlorinated biphenyls (PCBs). The 117 exposed women and men and 46 unexposed referents were studied together for simple and choice visual reaction time, body sway speed, blink reflex latency, color discrimination, Culture Fair (a nonverbal nonarithmetic intelligence test), recall of stories, figures, and numbers, cognitive and psychomotor control (slotted pegboard and trail making A and B), long-term memory, profile of mood states (POMS), and scores and frequencies of 34 symptoms. Choice reaction time, sway speed, and blink latency were impaired in both sexes of the exposed group and trail making B was impaired in exposed women. The POMS scores and frequencies of 30 of 34 symptoms were elevated in both sexes, compared to referents. Recall, long-term memory, psychomotor speed, and other cognitive function tests were reduced in exposed subjects and in the referents as compared to national referents. Neurophysiological impairment, and cognitive and psychomotor dysfunction and affective disorders, especially depression and excessive frequency of symptoms, were associated with the use of wells contaminated with VOCs, TCE and PCBs.

Trichloroethylene-induced hypersensitivity dermatitis is one of the serious occupational health events in China, however, little is known about the clinical features and possible mechanism of this disorder. The objective of the present study was to report some typical trichloroethylene-induced dermatitis patients and investigate their occupational exposure as well as the clinical features. We sampled and tested some cleaning agents from the companies where TCE-induced skin disorder occurred, the trichloroethylene concentrations were also monitored in the workplace air. Additionally, the symptoms, signs and laboratory test results of patients were collected. TCE concentrations varied from 10.2% to 91.4% in the cleaning agent by gas chromatography-mass chromatography analysis, and TCE levels in the workplace air ranged between 18 mg/m(3) and 683 mg/m(3), at most sampled sites TCE levels were higher than China national health standard for TCE. The trichloroethylene exposure time of the patients was 5-90 days (average 38.2 d), the patients with headache, dizziness, skin itch, fever were 90.5%, 100%, 100%, and 61.9%, respectively. 85.7% patients had skin erythema, 90.5% with rashes, and 38.1% with blisters. In addition, liver enlargement occurred in 3 patients, the abnormal rate of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (T-Bil) were 90.5%, 85.7% and 76.2%, respectively. 6 out of 15 patients were with abnormal electrocardiogram, and trichloroacetic acid (TCA) elevated in 14 patients (66.7%). Taken together, the major detrimental effect of trichloroethylene was to induce hypersensitivity dermatitis and liver dysfunction, the occurrence of this disorder is likely related to the individual hypersensitivity to trichloroethylene exposure.
