WASTE

Chemical

For waste sampling, use a spatula or soil drill. Sampling of loose waste from containers (car, car body, container, etc.) is made using a probe. Quantity and required volume of a waste sample depends on its aggregate state, moisture content, degree of uniformity and its granularity (for loose waste).

Sample weight must be at least 1 kg.

Store in containers made of chemically neutral material.

If the temperature is above 4-5 °C store for 2 days.

At temperatures below -20 °C store up to 30 days.

Conservation is not allowed

Dry residue, calcined dry residue

Sample weight must be at least 1 kg.

Samples are stored in glass containers with a tightly closed lid for no more than 3 days at a temperature of (4-8)°C.

Total alkalinity

Alkalinity free

Sample weight must be at least 1 kg.

Determination is carried out no later than 6 hours after sampling. Sample is not preserved. When sampling liquid samples, the container is filled to the top so that there are no air bubbles left. During transportation, samples should be protected from heating.

Cyanides

Samples are taken in containers (jars) of dark glass with a ground-glass or tightly screwed lid, filling the container under the top.

Store in containers made of chemically neutral material.

If the temperature is above 4-5 °C store for 2 days.

At temperatures below -20 °C store up to 30 days.

Bacteriological, Parasitological

Sample weight must be at least 1 kg.

At a temperature from 4 °C to 5 °C no more than 24 hours

Conservation is not allowed.

Radiological

Sample weight must be at least 1 kg.

Store in containers made of chemically neutral material.

If the temperature is above 4-5 °C store for 2 days.

At temperatures below -18 °C - up to 30 days.

Conservation is not allowed

Toxicological

Sample weight must be at least 1 kg.

Waste samples are not subjected to preservation. Samples must be sent to a laboratory no later than 12 hours after sampling. If it is impossible to perform the analysis within the specified period, samples are cooled to (+2)-(+4)°C. Under these conditions, samples of liquid and organic waste can be stored for no more than 1 day before analysis, and solid waste can be stored for no more than 1 week.
