文摘

Perchlorate (ClO₄⁻) is a common trace constituent of water, soils, and plants; it has both natural and synthetic sources and is subject to biodegradation. The stable isotope ratios of Cl and O provide three independent quantities for ClO₄⁻ source attribution and natural attenuation studies: δ³⁷Cl, δ¹⁸O, and δ¹⁷O (or Δ¹⁷O or ¹⁷Δ) values. Documented reference materials, calibration schemes, methods, and interferences will improve the reliability of such studies.
