1,2,4-Trichlorobenzene results

MS0240270 , HCUA-West

176 samples have been analysed for 1,2,4-Trichlorobenzene at HCUA-West.

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.

Every 1,2,4-Trichlorobenzene result

The table below lists 1–10 of 176 samples, newest first — collected March 6, 2024 to February 11, 2025.

10 1,2,4-Trichlorobenzene results from the 10 samples listed here: 0 detected, 10 not detected. Those samples also carried 200 results for other analytes, which are on the full results page.

1,2,4-Trichlorobenzene results for HCUA-West, from 1 to 10 of 176 samples shown analysed for it, newest first. This view leaves out other analytes on the same samples. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
