Abstract Introduction: Antimony trioxide (Sb2O3) has been utilized as a catalyst in polyethylene terephtalate (PET) production, and the studies conducted on the bottled water has demonstrated that antimony can be leached from PET bottles into drinking water. Methods: In this study, a simple method was applied in order to determine the trace amount of antimony in bottled drinking water bas...
Antimony ores were extracted and processed near the village of Milešov (Příbram district) for about twenty years in second halfof 19th century. Large heaps a small sludge pond left behind after this period. In 1988, locality was inspected andsampled order to gather information residual resources gold antimony. The original archive data from surveywere now studied again interpreted using modern ...
Due to the fact that metals and metalloids have a strong impact on the environment, the methods of their determination and speciation have received special attention in recent years. Arsenic, antimony, and thallium are important examples of such toxic elements. Their speciation is especially important in the environmental and biomedical fields because of their toxicity, bioavailability, and rea...
This study investigated antimony exposure among employees in industries in Taiwan and evaluated whether their immunologic markers were associated with antimony exposure. We recruited 91 male workers and 42 male office administrators from 2 glass manufacturing plants, 1 antimony trioxide manufacturing plants, and 2 engineering plastic manufacturing plants. Air samples were collected at worksites...
This study estimated the dietary exposure to antimony of secondary school students in Hong Kong and assessed the associated health risks. Dietary exposure to antimony was estimated using the local food consumption data obtained from secondary school students in 2000 and the concentrations of antimony in food samples taken from the local market. Laboratory analysis for antimony was conducted by ...
Antimonial-containing drugs are the first line of treatment against Leishmaniasis. Resistance to antimonials in Leishmania is proposed to be due to reduced uptake of trivalent antimony (SbIII) through the aquaglyceroporin (AQP1). We investigated the uptake of SbIII and involvement of aquaglyceroporin in developing antimony resistance phenotype in Leishmania donovani clinical isolates. SbIII acc...
Antimony (Sb) is a toxic metalloid that occurs widely at trace concentrations in soil, aquatic systems, and the atmosphere. Nowadays, with the development of its new industrial applications and the corresponding expansion of antimony mining activities, the phenomenon of antimony pollution has become an increasingly serious concern. In recent years, research interest in Sb has been growing and r...
Naturally occurring contamination of arsenic is of great concern in many Southeast Asian countries especially in Bangladesh. Because of the lack of understanding for the mechanism of As contamination, we have developed two studies through field surveys and laboratory experiments. First topic is focused on the underlying mechanisms controlling large spatial variation of As-contaminated groundwat...
