Article Synopsis
- Tire additives known as benzothiazole (BTs) are emitted into agricultural environments, and their uptake and metabolism in food crops, particularly in carrots, were evaluated to understand their behavior.
- Carrot plants readily absorbed BTs through their roots, but the upward movement to leaves was limited, with variations in translocation efficiency based on the specific BT structure.
- High-resolution mass spectrometry identified 18 novel BT metabolites in carrots, highlighting that transformation mainly occurs through glycosylation and amino acid conjugation, leading to structure-specific metabolic processes.
Enhanced emissions of brominated flame retardants from indoor sources by direct contact with dust.
Environ Monit Assess
February 2019
The emissions of brominated flame retardants (BFRs) from consumer products have been considered the major to the ubiquitous occurrence of contaminants in indoor environments. Direct contact with dust covering the surface of source materials in a real environment could introduce significant uncertainty. This study investigated the effects of dust coverage on the emissions of four BFRs, including 1, 2, 5, 6, 9, and 10-hexabromocyclododecane (HBCD), bis(2-ethyl-1-hexyl) tetrabromophthalate (BEHTBP), tetrabromobisphenol A (TBBPA), and hexabromobenzene (HBBZ), from decorative laminate, cotton sound insulation, PVC floor, and carpet.

Those compounds containing hydroxyl may undergo direct conjugation with endogenous biomolecules in plants, and potentially be preserved as conjugates, thus enabling overlooked risk via consumptions of food crops. In this study, we evaluated the uptake and metabolism of 2,4-dibromophenol (DBP) by both carrot cells and whole plant.
