Research advance on toxicity and occupational exposure limits of ethanolamine
-
Abstract
Ethanolamine (including monoethanolamine, diethanolamine, and triethanolamine) as an important raw material in chemical in dustry is widely applied in chemical products. It can affect human health by invading through respiratory tract, digestive tract, and skin. Animal studies have demonstrated that ethanolamine is irritating to skin and mucosa, hepatoxic, and nephrotoxic, but its effects on carcinogenesis and reproductive system are still controversial. Twenty-six countries/regions, including China, have set occupational exposure limits of monoethanolamine, but the limits of diethanolamine and triethanolamine are still absent in most countries/regions, including China. Due to the lack of occupational hygiene and occupational epidemiological studies to elucidate the impact of ethanolamine exposure on worker's health in actual occupational settings, the applicability of existed exposure limits remains to be assessed.
