Perchlorate concentration was the highest in Chilean nitrate, ranging from 3.3 to 3.98%. [51] Perchlorate in the solid fertilizer ranged from 0.7 to 2.0 mg g −1, variation of less than a factor of 3 and it is estimated that sodium nitrate fertilizers derived from Chilean caliche contain approximately 0.5–2 mg g −1 of perchlorate anion.
