It often contains other chemicals that give it a sharp, unpleasant smell. It's a colorless liquid that evaporates easily and has a sweet smell. Workers exposed to styrene concentrations of about 50 mg/m3 at a plant manufacturing reinforced polyester boats were examined for neuropsychiatric symptoms both in close connection with exposure and also seven months after exposure had ceased. Analysis A Cox proportional hazards model was used for risk analyses with the variance correction based on the published literature using SAS PHREG software ( 29 – 32 ).

We set out to assess the associations between two metrics of styrene exposure - estimated ambient concentrations and measured blood levels - and self-reported neurologic symptoms among Gulf state residents. Styrene may cause cancer, though it is still unknown. According to the studies, the long-term exposure to styrene gas can cause severe brain damage resulting in symptoms like headache, depression, delayed reaction time, reduced memory, slowed visuomotor speed (ability to integrate hands and eyes to complete a task) and reduced intellectual ability. Styrene gas is highly toxic and is regarded as a "known carcinogen". Signs and symptoms of Styrene exposure. The U.S. Environmental Protection Agency (EPA) has described styrene to be "a suspected toxin to the gastrointestinal tract, kidney, and respiratory system, among others" Immediate effects of inhalation of styrene gas can cause breathing difficulties, nausea and sore eyes.

Physical workload is important for the uptake of styrene and was about 50 W at this plant. Acute exposure may also result in gastrointestinal effects. A personal exposure matrix was established by matching the detailed job history with styrene and butadiene exposure concentrations by job code, calendar period, and plant. It is also known as vinylbenzene, ethenylbenzene, cinnamene, or phenylethylene. Chronic exposure to styrene in humans results in effects on the CNS, with symptoms such as headache, fatigue, weakness, depression, CNS dysfunction (reaction time, memory, visuomotor speed and accuracy, intellectual function), and hearing loss, peripheral neuropathy, minor effects on some kidney enzyme Health effects of styrene include irritation of the skin, eyes, and the upper respiratory tract.
