The samples will be analyze for microplastics. I have found research articles that used plastic bags or aluminum bags.
Dear Jean
USE a clean spade.
USE sterile whirl-pack bags (Hi-media) to avoid contamination.
DO NOT USE galvanized buckets cause it will contaminate the sample with zinc
DO NOT USE brass equipment of any kind as it will contaminate the samples with micronutrients.
RINSE the spade in between each use and with water to remove any visible debris and then 70% ethanol prior to the next sample collection.
Determine soil samples as sandy or clay depending on (% of sand, and clay)
Soil sampling Bags.
1. A chrome plated or stainless steel soil probe or auger. Shovels and spades may be used (see Fig attached), but they are inefficient.
2. A plastic bucket to mix the "cores" of soil in. Do not use equipment made of galvanized metal. The soil sample will be contaminated by the zinc in the galvanized metal.
3. A pen or marker with water-proof ink for labeling the soil bags.
4. We recommend that you take a clipboard or notebook and, if possible, field maps to record how the field was sampled.
Use cloth bags made from 100% cotton. You can also use aluminium containers if the sample size is less and no transportation is involved.
for the soil sampling, the sampling bags or a clean container can be used.
The bag used for sampling must always be clean and free from any
contamination. If the same bag is to be used for second time, turn it inside out and
remove the soil particles. Write the details of the sample in the information sheet like
name of the farmer, location of the farm, survey number, previous crop grown, present
crop, crop to be grown in the next season, date of collection, name of the sampler etc.,, Put a copy of this information sheet in the bag. Tie the mouth of the bag carefully.
Estoy de acuerdo con la recomendación de Rosana Goncalves, que el envase para recolectar muestras de suelo sean las bolsas de polietileno de alta densidad, ya que permiten contener todos los elementos a ser investigados.
Commonly soil sampling used Polyethylene bag, but even some times and depends on our sample purpose, use paper bag also.
To minimize the contamination of samples during sampling and analysis, standard non-plastic equipment, i.e. metal and glass, should be used as much as possible.
