Perchlorate – properties, toxicity and human health effects: an updated review
Reviews on Environmental Health, 2020 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 very persistent in nature and it is slowly degraded.

Effect of Nitrate, Acetate and Hydrogen on Native Perchlorate-reducing Microbial Communities and Their Activity in Vadose Soil [PDF]
, 2011 The effect of nitrate, acetate, and hydrogen on native perchlorate-reducing bacteria (PRB) was examined by conducting microcosm tests using vadose soil collected from a perchlorate-contaminated site.

Case Studies in Chemical and Environmental Engineering, 2021 Both perchlorate and black carbon (BC) are known for their common source of origin (i.e. burning processes, especially fireworks display), yet to our knowledge no study has focused on the effect of perchlorate (ClO4-) on the mobility of black carbon. The

Heats of formation of lithium perchlorate, ammonium perchlorate, and sodium perchlorate
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961 Calorimetric measurements of the heats of solution of LiClO4(c), NH4ClO4(e), and NaClO4(c) have been made. The results have been combined with the heats of formation of KClO4(c), KCl(c), LiCl(c), NH4Cl(c), and NaCl(c), to obtain the following heats of formation: LiClO 4 ( c ) , Δ Hf ° ( 25 ° C ) = - 380.27 ± 1.21 kj / mole = - 90.89 ± 0.29 ...
