![]() Given our lack of understanding of the health impacts of Sb, more studies on its toxicity and mobility from commonly encountered products are called for. Available data in the literature suggests that, while Sb concentrations up to 30 μg g − 1 are bioaccessible in exterior paints and that concentrations of up to 20 mg L − 1 are migratable in some ceramicware, no relevant regulations are currently in place. Other performance enhancing additives include zinc stannate and ammonium octamolybdate. Antimony trioxide is the most important of the antimony compounds and is primarily used in flame- retardant applications, including such markets, as childrens. 3 Also, zinc borate can be used to reduce the amount of antimony trioxide. Antimony trioxide is a compound produced from antimony, a lustrous gray metalloid, or naturally occurring antimony-oxide containing minerals. Overall, the yellow pigment, lead antimonate, was only evident in two ceramic products analysed, with Sb concentrations exceeding 62,800 μg g − 1. Antimony oxide can be advantageously combined with huntite/hydromagnesite fillers to offer excellent flame retarding properties. Antimony was also found in contemporary container glass and ceramic products as an additive or opacifier and as a colour fastener in enamels at concentrations up to a few thousand μg g − 1. artistic) nature, but was common in old household paints as an anti-chalking agent and in brightly-coloured contemporary exterior paints (on roads, street furniture and playground equipment, for example) as a colour fastener with concentrations ranging from a few hundred to about 25,000 μg g − 1. The metalloid was only present in consumer paints of a speciality (e.g. ![]() Concentrations of antimony have been determined for paints and enamels that are available to the consumer or accessible to the public by x-ray fluorescence spectrometry.
