TAILIEUCHUNG - Trichloroethylene (TCE): TEACH Chemical Summary

Severe chemical contamination was found in ash contaminated soil samples from open burning sites at both Agbogbloshie and Korforidua, as well as in sediment from a shallow lagoon at the Agbogbloshie site. Most samples contained numerous toxic and persistent organic chemical pollutants, as well as very high levels of many toxic metals, the majority of which are either known to be used in electronic devices, or are likely to be formed during the open- burning of materials used in such devices. The nature and extent of chemical contamination found at these sites in Ghana were similar to those previously reported for e-waste open burning sites in. | Trichloroethylene TCE TEACH Chemical Summary . EPA Toxicity and Exposure Assessment for Children s Health This TEACH Chemical Summary is a compilation of information derived primarily from . EPA and ATSDR resources and the TEACH Database. The TEACH Database contains summaries of research studies pertaining to developmental exposure and or health effects for each chemical or chemical group. TEACH does not perform any evaluation of the validity or quality of these research studies. Research studies that are specific for adults are not included in the TEACH Database and typically are not described in the TEACH Chemical Summary. I. INTRODUCTION Trichloroethylene TCE is a volatile organic chemical VOC used primarily as an industrial solvent 1 . TCE is a colorless or blue liquid with a sweet chloroform-like odor. The most common use of TCE is to remove grease from fabricated metal parts and some textiles. It is also an ingredient in adhesives paint removers typewriter correction fluids rug-cleaning fluids spot removers and pepper sprays 1-3 . The most recent available report of . production stated a production volume of 321 million pounds of TCE in 1991 production capacity in the . was approximately 320 million pounds at that time 1 . TCE has been found in ambient air surface water and ground water 1 4-9 . TCE levels above background have been found in industrial settings in homes undergoing renovation and in homes using private wells located near TCE disposal or contamination sites 1 4-6 . The most likely TCE exposure route for children is ingestion of contaminated drinking water 1 . Exposure to TCE has been reported to have adverse effects on the central nervous system immune system and endocrine hormonal system in adults 1 . Reported effects often involve the central nervous system with reported symptoms of fatigue sleepiness headache confusion and blurred vision 1 3 . Other effects on liver kidney gastrointestinal tract and skin have been reported 1 3 . .
