Trichloroethylene: An Update on an Environmental Contaminant with Multiple Health Effects

The halogenated solvent trichloroethylene (TCE) has had many uses in medicine, construction, consumer products, and the military. Many of these uses have been discontinued or restricted due to its toxicity, which affects multiple target organs and includes both acute, high-dose toxicity and chronic, low-dose toxicity that also encompass several cancers. US and international agencies have conducted risk and hazard assessments for TCE, with comprehensive publications coming out in the last 10-15 years. Accordingly, the focus of this article is to review recently published data since that time (i.e., 2014) that clarify unsettled questions or provide additional insights into the metabolism and mechanisms of toxicity of TCE in several target organs. Besides metabolism, the review focuses on the kidneys, liver, immune system, nervous system, cardiovascular and pulmonary systems, the search for biomarkers, and recent analyses of human cancer risk and incidence from TCE exposure.

Preventing Parkinson's Disease: An Environmental Agenda

Fueled by aging populations and continued environmental contamination, the global burden of Parkinson's disease (PD) is increasing. The disease, or more appropriately diseases, have multiple environmental and genetic influences but no approved disease modifying therapy. Additionally, efforts to prevent this debilitating disease have been limited. As numerous environmental contaminants (e.g., pesticides, metals, industrial chemicals) are implicated in PD, disease prevention is possible. To reduce the burden of PD, we have compiled preclinical and clinical research priorities that highlight both disease prediction and primary prevention. Though not exhaustive, the "PD prevention agenda" builds upon many years of research by our colleagues and proposes next steps through the lens of modifiable risk factors. The agenda identifies ten specific areas of further inquiry and considers the funding and policy changes that will be necessary to help prevent the world's fastest growing brain disease.
