If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

PBBs的毒性确切机制因具体同系物而异。据信，主要的相互作用涉及芳基烃受体（AhR）。PBBs与AhR结合并激活它，进而启动一系列基因的转录上调，影响生化与内分泌途径、细胞周期调控、形态发生、氧化应激反应以及其他各种过程。这导致了PBBs的多种毒性反应特征。一些已知的诱导基因包括细胞色素P-450依赖性单加氧酶CYP1A1和CYP1A2。(L628)
