Organophosphorus flame retardants (flame retardants, FRs) have been used for several decades in many industries, including the production of dyes, varnishes, adhesives, synthetic resins, polyvinyl chloride, hydraulic fluids, plastics and textiles. Their importance in recent times has increased due to i.a., significantly reduced use of polybrominated diphenyl ethers (PBDEs) – persistent organic pollutants, dangerous for the environment. The aim of this study was to review the available literature data concerning phosphorous FRs primarily for neurotoxic, fertility, reproductive and carcinogenic effects. The analysis concerned the following most commonly used substances: tris(2-ethylhexyl)phosphate (TEHP), tris(2-butoxyethyl)phosphate (TBEP), triphenyl phosphate (TPP), tris(2-chloroethyl)phosphate (TCEP), tetrakis(hydroxymethyl)-phosphonium chloride (THPC), tributyl phosphate (TBP), tricresyl phosphate (TCP), tris(2-chloroisopropyl)phosphate (TCPP), tris(1,3-dichloroisopropyl)phosphate (TDCP) and tetrakis(hydroxymethyl) phosphonium sulphate (THPS). In animal studies neurotoxic effects were found after exposure to TBEP, THPC, TBP and TCP, while in humans they were observed only after exposure to TCP. TCEP, THPS, TBP, TCP and TDCP caused disorders in fertility and/or fetal development of animals. Adverse effects on reproduction in humans may be caused by TPP, TCP, and TDCP. In laboratory animals the development of tumors was observed after high doses of TEHP, TCEP, TBP and TDCP. None of these compounds is classified as a human carcinogen. The environmental toxicity of phosphate FRs is low (except for TPP, TCEP and TBEP). They are not stable compounds, in living organisms they are metabolised and quickly excreted. Therefore, they can be used as an alternative to PBDEs. Med Pr 2015;66(2):235–264

Fosforowe związki organiczne zmniejszające palność (flame retardants – FRs) stosowane są od kilkudziesięciu lat w wielu gałęziach przemysłu, m.in. w produkcji barwników, lakierów, klejów, syntetycznych żywic, polichlorku winylu, płynów hydraulicznych, tworzyw sztucznych i tekstyliów. Ostatnio ich znaczenie wzrasta, co spowodowane jest m.in. znacznym ograniczeniem stosowanych dotąd polibromowanych difenyloeterów (PBDEs) – niebezpiecznych dla środowiska trwałych zanieczyszczeń organicznych. Celem pracy był przegląd dostępnych danych literaturowych dotyczących fosforowych FRs przede wszystkim pod kątem ich działania neurotoksycznego, wpływu na płodność i rozrodczość oraz działania kancerogennego. Analiza dotyczyła najczęściej stosowanych substancji, którymi są: fosforan trietyloheksylu (TEHP), fosforan tributoksyetylu (TBEP), fosforan trifenylu (TPP), fosforan tris(2-chloroetylu) (TCEP), chlorek tetra(hydroksymetylo)fosfoniowy (THPC), fosforan tributylu (TBP), fosforan trikrezolu (TCP), fosforan tris(2-chloro-1-metyloetylu) (TCPP), fosforan tri(1,3-dichloroizopropylu) (TDCP) oraz siarczan tetrakis(hydroksymetylo) fosfoniowy (THPS). Działanie neurotoksyczne wykazano w badaniach na zwierzętach po narażeniu na TBEP, THPC, TBP i TCP. U ludzi działanie neurotoksyczne zaobserwowano tylko po narażeniu na TCP. Z kolei TCEP, THPS, TBP, TCP i TDCP powodowały zaburzenia płodności i/lub w rozwoju płodów zwierząt. Niekorzystny wpływ na rozrodczość u ludzi mogą powodować TPP, TCP i TDCP. Nowotwory u zwierząt laboratoryjnych powodowały podawane w wysokich dawkach THEP, TCEP, TBP i TDCP. Żaden z tych związków nie jest jednak klasyfikowany jako rakotwórczy dla ludzi. Toksyczność środowiskowa fosforowych FRs jest niewielka (z wyjątkiem TPP, TCEP i TBEP). Nie są one związkami trwałymi, w organizmach żywych podlegają przemianom metabolicznym i są z nich szybko wydalane. Mogą być więc alternatywą dla stosowanych do niedawna PBDEs. Med.

BackgroundAllergic reactions to metals and metal salts used in tattoo pigments occur surprisingly frequently. For this reason, this study focused on the determination of thallium (Tl) in the samples of color tattoo inks. These inks are commonly used in tattooing processes worldwide.Material and MethodsThe samples were analyzed with the use of differential pulse anodic stripping voltammetry. The stripping anodic peak current of Tl was linear over its concentration range of 0.5–6.0 μg/l, which corresponds to 2.45×10–9–2.94×10–8 M. The determined value of the limit of detection (LOD) was equal to 0.149 μg/l (7.29×10–10 M).ResultsThe obtained results revealed a wide range of Tl contents in tattoo inks, i.e., 0.0029–0.4275 μg/g. The content of this metal varied substantially depending on the pigment used in tattoo inks.ConclusionsThallium was identified and determined in all tested samples. Its content depends on the country of origin but it does not depend directly on the color. The lowest content of Tl was found in the pink ink and the highest in the violet ink (from Israel), and a similar content was also found in the yellow ink (from Israel). The use of colored inks in larger quantities (a dense pattern and a larger surface area covered) may potentially pose a health risk. The danger of Tl poisoning from tattooing depends on the type of the ink (color) and its origin. As Tl is not considered a micronutrient, introducing such a Tl content into the body may be associated with a potentially harmful accumulation of this metal in body organs, causing various types of ailments and toxic effects primarily on the nervous, skeletal and circulatory systems. The obtained results suggest that tattooists may be exposed to the toxic effects of Tl in tattoo inks. The analytical data presented in the paper may constitute the basis for determining the acceptable limits of toxic Tl contents in tattoo inks. Med Pr. 2020;71(4):405–11
