Cyanide results

MS0240135 , Lizana Elementary School

21 samples have been analysed for Cyanide at Lizana Elementary School.

This is one analyte out of the system’s whole record. For what has ever been detected here, and when, see all chemical and radiological results; for everything the system is tested for, see the analyte list.

What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.

No date range is applied: this list draws on every sample on record. Show the last two years only.
