Siv nyob rau hauv cov tshuaj dyeing kev lag luam, thiab raws li ib tug kho tus neeg sawv cev rau plastics, thiab lwm yam. Nws tuaj yeem nkag mus rau tib neeg lub cev los ntawm kev ua pa, tawv nqaij thiab plab hnyuv.Cov tshuaj lom neeg mob hnyav tuaj yeem ua rau methemoglobinemia, daim siab puas thiab hemolytic anemia.

Lub ntsiab siv thiab kev ua haujlwm ntawm phenylenediamine:
