TL;DR: In this article, the authors investigated the properties of organo(oxinato)antimony(V) compounds and showed that the stability of the SbN coordinate bond in R4SbOx follows the order of the I-effect of the group R. All the compounds are monomeric in benzene.

TL;DR: In this article, the authors used hydride generation inductively coupled plasma atomic emission spectrometry (HG-ICP-AES) based on pre-reduction kinetics of antimony to antimony(III) with l -cysteine.

TL;DR: A new procedure was elaborated to determine mercury(II) using an anodic stripping square-wave voltammetry at the antimony film carbon paste electrode (SbF-CPE) using in highly acidic medium of 1M hydrochloric acid, voltammetric measurements can be realized in a wide potential window.

TL;DR: The investigation indicates that the two antimony compounds show virtually equal pulmonary absorption and renal elimination and form the basis for proposals regarding appropriate biological exposure limits for occupational antimony exposure.
Abstract: In the production of lead batteries two antimony compounds occur: in the casting of grids antimony trioxide (Sb2O3), and in the formation of lead plates stibine (SbH3). Seven workers from the grid-casting area and 14 workers from the formation area were examined with regard to the antimony concentration in blood (Sb-B) and urine (Sb-U). Antimony air concentrations (Sb-A) were measured by means of personal air samplers. Urine samples were collected at the end of the working week, at the beginning (U1) and the end (U2) of the shift, and at the beginning of work following a weekend without Sb exposure (U3). At U2 among the casters, the median Sb-A exposure was 4.5 (1.18-6.6) micrograms Sb/m3 and among the formation workers, 12.4 (0.6-41.5) micrograms Sb/m3. The exposure in both groups is more than 10 times lower than the present threshold limit values. The median Sb-B concentrations in the preshift samples was 2.6 (0.5-3.4) micrograms Sb/l for the casters and 10.1 (0.5-17.9) micrograms Sb/l for the formation workers. The average Sb-U values (U2) were 3.9 (2.8-5.6) micrograms Sb/g creatinine in the casting area and 15.2 (3.5-23.4) micrograms Sb/g creatinine in the forming area. Our investigation indicates that the two antimony compounds show virtually equal pulmonary absorption and renal elimination. The statistically significant correlations between Sb-A/Sb-B and Sb-A/Sb-U form the basis for proposals regarding appropriate biological exposure limits for occupational antimony exposure.

TL;DR: The occupational exposure, clinical findings, lung function and radiological characteristics of 51 workers in an antimony smelting plant are presented and the pneumoconiotic changes developed after at least one decade of work are presented.
Abstract: The occupational exposure, clinical findings, lung function and radiological characteristics of 51 workers in an antimony smelting plant are presented. The workers were exposed to the airbone dust containing a high concentration of antimony trioxide (up to 88%) and antimony pentoxide.
