Why is Antimony being Regulated? In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine safe levels of chemicals in drinking water which do or may cause health problems. These non-enforceable levels, based solely on possible health risks and exposure, are called Maximum Contaminant Level Goals.
Maximum Contaminant Levels for Drinking Water. *** The average annual concentration of beta particle and photon radioactivity from manmade radionuclides in drinking water shall not produce an annual dose equivalent to the total body or any internal organ greater than four (4) millirem per year. **** The sum of the concentrations of ...

With respect to genotoxicity and metabolism, we and others have shown that antimony is able to modulate arsenic's toxicity.These findings may be important, because several cases are known where soil contamination with arsenic is accompanied by co-contamination with antimony ().In case of contact with aquifers, this could lead to co-contamination of drinking …
The range of pH was 6-8, which is common for drinking water. This factor does not affect leaching. However, the dissolution rate of antimony in sparkling water, which has a lower pH (4-5), is higher than in pure water. In a study at pH 4, the antimony concentration increased from 0.46 a 4.61 µg/L. Major differences were found regarding the PET ...
If the source of antimony is corrosion of antimony-containing plumbing materials, consider the following options: • Remove the source of antimony. • Flush faucets until the water runs as cold as possible before using the water for drinking, cooking, or teeth brushing. • Avoid using hot tap water for drinking, cooking, or making baby formula.

The World Health Organization (WHO) and the US Environmental Protection Agency (EPA) have set the maximum allowable concentration of Sb in drinking water as 20 μg L −1 and 6 μg L −1, respectively [7,8]. Therefore, it is of great importance for monitoring of Sb in environment and drinking water samples.
Antimony (Sb) traces in water pose a serious threat to human health due to their negative effects. In this work, nanoscale zero-valent iron (Fe0) supported on activated carbon (nZVI) was employed for eliminating Sb(V) from the drinking water. To better understand the overall process, the effects of several experimental variables, including pH, dissolved oxygen …

Antimony, cobalt, and acetaldehyde migration into the drinking water (PET bottled) was tracked for every 2 months through a year. Migration of these compounds rose with increased storage time at 20°C. The highest amounts of migrated compounds were observed in 0.5 L (smallest) of PET bottles.
This study evaluates the efficiency of iron-based oxy-hydroxides to remove antimony from groundwater to meet the requirements of drinking water regulations. Results obtained by batch adsorption experiments indicated that the qualified iron oxy-hydroxide (FeOOH), synthesized at pH 4 for maintaining a high positive charge density (2.5 mmol OH−/g) achieved a residual …

Antimony is a regulated contaminant that poses both acute and chronic health effects in drinking water. Previous reports suggest that polyethylene terephthalate (PET) plastics used for water bottles in Europe and Canada leach antimony, but no studies on bottled water in the United States have previously been conducted.
A number of studies have been published on the quantification of antimony in PET bottles and migration of antimony into water, juice, soft drinks, and into simulants. An overview of these studies can be found in Table 1. The studies showed that the concentration of Sb in PET bottles was in the range of 104 to 323 mg kg −1, but the migration ...
