ObjectiveAssociations between occupational styrene exposures and impairment of visual functions were investigated with a view to answering three questions: (1) are the published findings for colour vision deficiencies and impaired contrast sensitivity to reproduce in a new study approach, (2) if such effects exist, are they related to current or chronic exposures and (3) if effects exist, are there reductions in the effects during an exposure-free period?MethodsWorkers from a boat building… Expand
Occupational styrene exposure and neurobehavioural functions: a cohort study with repeated measurements
TLDR
Acute exposures to up to 40 ppm styrene and long-term exposures to about 27 ppM averaged over a period of 15 years were not identified as being associated with an elevated risk of developing impaired cognitive and psychomotor functions or increased symptom levels with the tests applied. Expand
Environmental Styrene Exposure and Sensory and Motor Function in Gulf Coast Residents
TLDR
Assessment of styrene-associated differences in sensory and motor function among Gulf coast residents found associations between higher styrene exposure and poorer visual, sensory, and vestibular function, though it did not detect associations with reduced voluntary motor system performance. Expand
Occupational styrene exposure and acquired dyschromatopsia: A systematic review and meta‐analysis
TLDR
This review confirms the hypothesis of occupational styrene-induced dyschromatopsia, suggesting a modest effect size with mild heterogeneity between studies, and assesses between-study heterogeneity and publication bias. Expand
Styrene-associated health outcomes at a windblade manufacturing plant.
TLDR
Despite styrene exposures below the recommended 400 mg/g creatinine, visual and respiratory effects indicate the need for additional preventative measures in this industry. Expand
Retinal and visual system: occupational and environmental toxicology.

TLDR
The findings elucidate the importance of conducting multimodal noninvasive clinical, electrophysiologic, imaging and vision testing to monitor toxicant-exposed workers for possible retinal/visual system alterations. Expand
Toluene inhalation exposure for 13 weeks causes persistent changes in electroretinograms of Long-Evans rats.
TLDR
Experimental evidence is provided that repeated exposure to toluene may lead to subtle persistent changes in visual function, and that elements in the rat retina may be more sensitive to organic solvent exposure than the rat visual cortex. Expand
Evaluation of potential health effects associated with occupational and environmental exposure to styrene – an update

TLDR
The updated hazard assessment of styrene’s health effects indicates human cancers and ototoxicity remain potential concerns, however, mechanistic research on mouse lung tumors demonstrates these tumors are mouse-specific and of low relevance to human cancer risk. Expand
Derivation of safe health-based exposure limits for potential consumer exposure to styrene migrating into food from food containers.
TLDR
This assessment supports a health based Specific Migration Limit of 90 ppm, a value somewhat higher than the current overall migration limit in the European Union, and based on criteria of science and health protection converged to the range of 90-120 mg/person/d. Expand
Health effects of wind turbines in working environments - a scoping review.
TLDR
The findings of the included studies indicate that substances used in rotor blade manufacture cause skin disorders and respectively, respiratory ailments and eye complaints; exposure to onshore wind turbine noise leads to annoyance, sleep disorders, and lowered general health; working in the wind industry is associated with a considerable accident rate, resulting in injuries or fatalities.

Occupational styrene exposure and neurobehavioural functions: a cohort study with repeated measurements
TLDR
Acute exposures to up to 40 ppm styrene and long-term exposures to about 27 ppM averaged over a period of 15 years were not identified as being associated with an elevated risk of developing impaired cognitive and psychomotor functions or increased symptom levels with the tests applied. Expand
Occupational styrene exposure and hearing loss: a cohort study with repeated measurements
TLDR
This study found, that chronic and intensive styrene exposure increases the hearing thresholds, and improvements of hearing thresholds during work- and exposure-free period are possible. Expand
Effects of low-level occupational exposure to styrene on color vision: dose relation with a urinary metabolite.
TLDR
This study suggests that a low level of styrene, presumably 0.1-0.2 g/L, involves the risk of inducing adverse effects on color vision, and suggests a dose-dependent relationship between the urinary concentration of mandelic acid and color vision loss. Expand
Colour vision and occupational toluene exposure: results of repeated examinations.
TLDR
Current industrial exposure limits of toluene provide sufficient protection against possible disturbance of colour vision, and age and occupational qualification were significantly associated with CCI in both kinds of analysis. Expand
Visual dysfunction among styrene-exposed workers.
TLDR
There is a positive relation between styrene exposure and early color and contrast vision dysfunction, and Logistic multiple regression models indicated that the end-shift concentration of urinary mandelic acid was related to the prevalences of blurred vision, tearing, and eye irritation. Expand
Relation between colour vision loss and occupational styrene exposure level
TLDR
Exposure to styrene would impair colour vision even if the exposure concentration was lower than 10 ppm, and if the maximum concentration of styrene exposure transiently exceeded 50 ppm in the past, the styrene related damage might remain. Expand
Low-level styrene exposure and color vision in Swedish styrene workers.
TLDR
It is indicated that styrene exposure even at levels below the current Swedish OEL of 20mg/m(3) may affect color vision negatively, and effects on the Vingrys' color vision confusion index are revealed. Expand
Intervention Study on Acquired Color Vision Deficiencies in Styrene-Exposed Workers
TLDR
It is concluded that Styrene-induced color vision dysfunction is reversible after an exposure-free interval of 4 weeks, and the current Biological Tolerance Value of 600 mg mandelic acid plus phenylglyoxcylic acid per gram creatinine, as used in Germany, protects styrene-exposed workers from this subclinical effect. Expand
Cumulative exposure to styrene and visual functions.
TLDR
Findings suggest that CS loss increases with long-term cumulative exposure, reflecting chronic damage to the neuro-optic pathways. Expand
Impairments of colour vision induced by organic solvents: a meta-analysis study.
TLDR
The impairment of colour discrimination induced by occupational exposure to toluene, styrene and mixtures of organic solvents is reviewed and analysed using a meta-analytical approach, indicating that in the great majority of the studies the exposed groups showed inferior colour discrimination.
