Final answer:
Bulk samples are taken for analysis to identify asbestos in building materials. Preparation of samples involves crushing the material to finer grains for analysis, particularly in understanding mineral composition. Different solids sampling methods are used based on the material type to ensure representative samples.
Explanation:
Bulk samples are taken to a laboratory to identify if a building material contains asbestos. These samples represent the overall composition of the material. The extraction process involves collecting a large quantity of the material for analysis.
Lithology is determined by preparing a sample from the bulk sediment, which includes crushing the material into finer grains. This process allows for further analysis to understand the mineral composition.
Solids sampling methods vary based on the material type, with larger particulates like ores being sampled using techniques like riffles to obtain representative samples for analysis.
