Acute health effects of styrene are generally irritation of the skin, eyes, and the upper respiratory tract. Acute exposure also results in gastrointestinal effects. Chronic exposure affects the central nervous system showing symptoms such as depression, headache, fatigue, weakness, and may cause minor effects on kidney function.
