AMMC designates samples from the Amazon Macrotidal Mangrove Coast from Pará and Maranhão States.
By designating samples with values below the detection limit as having values of 3 pmol/l a mean suppression of 88% may be calculated, but this is inevitably an underestimate.
On the basis of these groupings, we designated samples VS25, VS28, VM75, and VM82 as group 1; samples VS14 and VM88 as group 2; VS32, VS33, VM40, VM55, VM55, and VM71 as group 3; and VS63 as group 4. From each of these groupings, we selected 1 sequence to represent the entire group.
To arrive at the designated sample size, systematic random sampling was used.
An aliquot of 0.5 mL of the supernatant solution was removed from each vial at the designated sampling intervals and replaced with the same amount of fresh buffer.
The respondents were interviewed along those lines, e.g. starting from the first landmark, the first four households were skipped, and the fifth household was considered for the interview; this exercise continued until the designated sample size was achieved.

At the designated sampling intervals, each specimen was removed from the container, rinsed with 10 ml normal saline and placed in a fresh 5-ml bath in a fresh container.
But the monitors, which MSHA says cost between $13,000 and $15,000 apiece, will be used only by certain miners during designated sampling periods, much like the dust pumps now in use.
