Interest in perchlorate as environmental pollutant has increased since 1997, when high
concentrations have been found in the waters of the Colorado River, USA. Perchlorate is …

Perchlorate, an iodide uptake inhibitor, is increasingly being detected in new places and
new matrices. Perchlorate contamination has been attributed largely to the manufacture and …

This paper reviews the unique situation of perchlorate contamination in Chile, including its
sources, presence in environmental media and in the human population, and possible steps …

Abstract Perchlorate (ClO4−) is an emerging contaminant whose presence and origin is of
considerable environmental interest. This article discusses known sources of perchlorate …

The national occurrence of perchlorate in drinking water was analyzed and mapped by
compiling data from existing perchlorate occurrence surveys. The existing surveys included …

Abstract Perchlorate (ClO 4−) in groundwater can be from synthetic or natural sources.
Natural sources include ClO 4− associated with historical application of imported natural …

The issue of naturally-occurring perchlorate is one that has environmental, agricultural, and
economic implications. Natural perchlorate was first identified in Chilean nitrates over 100 …

Abstract Perchlorate (ClO 4−) has synthetic and natural sources. Synthetic ClO 4− is
released to the environment from its use as an oxidant in military and aerospace …

Conclusions The frequency of detection of perchlorate impacts to soil, groundwater and
surface water, unrelated to military activities, is likely to increase as water utilities analyze for …

Lowering the federal standard for arsenic in drinking water from 50 µg/L to 10 µg/L has
led to a much wider spread of arsenic contamination in groundwater across Texas. This …
