Health effects of styrene include irritation of the skin, eyes, and the upper respiratory tract. Acute exposure may also result in gastrointestinal effects.
How long does styrene stay in your system?
After an 8-hour exposure of workers to styrene at concentrations of 26–130 mg/m3 (6.1–30.5 ppm), both metabolites have a half-life of about 2.5 hour for the first phase and 30 hours for the second (35). These compounds are used in assessing occupational exposure to styrene.
Is styrene toxic to inhale?
Summary of Health Effects Styrene is readily absorbed and can result in toxicity following inhalation and dermal exposure [1-3]. Although no cases of styrene ingestion have been reported in humans, it is expected to give rise to systemic toxicity, similar to that seen following inhalation [1, 2].
How is styrene poisoning treated?
The only treatment for styrene toxicity is treating the effects and symptoms of exposure and avoiding re-exposure to styrene. This includes monitoring for styrene-related cancers and tumors. 1. Agency for Toxic Substances and Disease Registry (ATSDR).
Should I be worried about styrene?
The human health effects from exposure to low environmental levels of styrene are unknown. Workers exposed to large amounts of styrene can develop irritation of the eyes and breathing passages. With long-term and large exposures, workers using styrene have had injury to their nervous systems.
Can styrene cause depression?
Chronic (long-term) exposure to styrene in humans results in effects on the central nervous system (CNS), such as headache, fatigue, weakness, and depression, CSN dysfunction, hearing loss, and peripheral neuropathy.
What does styrene smell like?

- Stop smoking. Styrene is found in tobacco smoke.
- Limit children’s exposure to tobacco smoke.
- Adhere to federal workplace regulations.
How does a TV expose you to styrene?
The television contained flame retardants at percentage levels by weight in the plastic, meaning the chemicals make up a significant portion of the product. These chemicals can migrate out of televisions and get into indoor air, household dust, and make their way into bodies, posing risks to families and pets.
How do you filter styrene?
You can safely remove styrene to below 100 ppb through the use of Reverse Osmosis (RO) and granular activated carbon (GAC). Get a whole house water filter system designed to filter out harmful contaminants like styrene. Protect your family from the health effects of chemical compounds with a reliable water filter unit.
Why is styrene used?
Styrene is a chemical used to make latex, synthetic rubber, and polystyrene resins. These resins are used to make plastic packaging, disposable cups and containers, insulation, and other products. Styrene is also produced naturally in some plants. People may be exposed to styrene by breathing it in the air.
What does AN/TPQ-53 mean?
The AN/TPQ-53 is a counterfire target acquisition radar designed and manufactured by the U.S. Company Lockheed Martin. The U.S. Army changed the designation of the Enhanced AN / TPQ-36 (EQ-36) radar to the AN/TPQ-53 (Q-53) radar in September 2011.
Is the TPQ-53 radar system in the US Army?
The system has been tested and has been accepted by the US Army. TPQ-53 radar systems will replace the aging TPQ-36 and TPQ-37 medium-range radars now in the Army’s inventory. In addition to its counter-fire and counter-drone missions, Prior to September 2011 This system was known as EQ-36 Counterfire Target Acquisition Radar.
How long has the q-53 been in combat?
The Q-53 has operated successfully in combat since 2010. Soldiers can use 90 or 360 degree modes for detection of mortars, rockets and artillery. Compared to the Q-36 and Q-37 systems, the Q-53 provides significant cost, footprint, and manpower reduction.
What is q-53 radar used for?
The Q-53 is a mobile radar system designed to detect, classify, and track projectiles fired from mortar, artillery, and rocket systems using a 90-degree or continuous 360-degree sector search. The radar provides target location of threat indirect fire systems with sufficient accuracy for effective counterfire.
