Background: This paper presents the results of the quantitative study of the airborne chemical substances detected in the conservator's work environment. Material and Methods: The quantitative tests were carried out in 6 museum easel paintings conservation studios. The air test samples were taken at various stages of restoration works, such as cleaning, doubling, impregnation, varnishing, retouching, just to name a few. The chemical substances in the sampled air were measured by the GC-FID (gas chromatography with flame ionization detector) test method. Results: The study results demonstrated that concentrations of airborne substances, e.g., toluene, 1,4-dioxane, turpentine and white spirit in the work environment of paintings conservators exceeded the values allowed by hygiene standards. It was found that exposure levels to the same chemical agents, released during similar activities, varied for different paintings conservation studios. It is likely that this discrepancy resulted from the indoor air exchange system for a given studio (e.g. type of ventilation and its efficiency), the size of the object under maintenance, and also from the methodology and protection used by individual employees. Conclusions: The levels of organic solvent vapors, present in the workplace air in the course of painting conservation, were found to be well above the occupational exposure limits, thus posing a threat to the worker's health.

Wstęp: W artykule przedstawiono wyniki badań ilościowych substancji chemicznych występujących w powietrzu stanowisk pracy konserwatorów malarstwa. Materiały i metody: Badania przeprowadzono w 6 muzealnych pracowniach konserwacji malarstwa. Próbki powietrza do badań pobierano na różnych etapach prac konserwatorskich (czyszczenie, dublowanie, impregnacja, werniksowanie, retusz). Analizę ilościową substancji chemicznych w pobranych próbkach powietrza prowadzono metodą chromatografii gazowej z detekcją płomieniowo-jonizacyjną (gas chromatography with flame ionization detector - GC-FID). Wyniki: Podczas badań w powietrzu środowiska pracy konserwatora malarstwa substancje takie, jak toluen, 1,4-dioksan, terpentyna i benzyna do lakierów występowały w stężeniach znacznie przekraczających wartości normatywów higienicznych. Narażenie na te same czynniki chemiczne podczas wykonywania podobnych czynności w badanych pracowniach było różne. To zróżnicowanie wynika ze sposobu wymiany powietrza w pomieszczeniach (rodzaju wentylacji i jej sprawności), wielkości obiektu poddawanego konserwacji, ale także od sposobu prowadzenia prac przez pracowników i stosowania środków prewencji. Wnioski: Podczas wykonywania prac konserwatorskich pary niektórych rozpuszczalników organicznych występują w powietrzu w ilościach znacznie przekraczających najwyższe dopuszczalne stężenia, stanowiąc zagrożenie dla zdrowia pracowników.

Objectives Veterans of the 1991 Gulf War (GW) were exposed to a myriad of potentially hazardous chemicals during deployment. Epidemiological data suggest a possible link between chemical exposures and Parkinson’s disease (PD); however, there have been no reliable data on the incidence or prevalence of PD among GW veterans to date. This study included the following 2 questions: 1. Do deployed GW veterans display PD-like symptoms? and 2. Is there a relationship between the occurrence and quantity of PD-like symptoms, and the levels of deployment-related exposures in GW veterans? Material and Methods Self-reports of symptoms and exposures to deployment-related chemicals were filled out by 293 GW veterans, 202 of whom had undergone 3 Tesla volumetric measurements of basal ganglia volumes. Correlation analyses were used to examine the relationship between the frequency of the veterans’ self-reported exposures to deployment-related chemicals, motor and non-motor symptoms of PD, and the total basal ganglia volumes. Results Healthy deployed GW veterans self-reported few PD-like non-motor symptoms and no motor symptoms. In contrast, GW veterans with Gulf War illness (GWI) self-reported more PD-like motor and non-motor symptoms, and more GW-related exposures. Compared to healthy deployed veterans, those with GWI also had lower total basal ganglia volumes. Conclusions Although little is known about the long-term consequences of GWI, findings from this study suggest that veterans with GWI show more symptoms as those seen in PD/prodromal PD, compared to healthy deployed GW veterans.
