Field/Intervention experiment

Water samples from the streams were collected using Teledyne ISCO 6712 portable automatic samplers. The samplers were equipped with 8 of 1.8L glass bottles. These samplers were programmed to take time-proportional sub-samples. The samples were collected 0.5 m below the stream surface. The time intervals for sampling were determined based on the predicted precipitation duration during wet weather. For dry weather sampling, the intervals were consistently set to one hour, with sampling conducted over a 24-hour period. After each sampling event, sub-samples were thoroughly mixed and composited to create a 7.2 L composite sample from each site. The samples were then submitted to ALS Scandinavia AB. Bottom sediment samples were collected using a powder-coated brass Ekman sediment sampler (Hydro-Bios). Several grab samples were collected, thoroughly mixed and homogenized, and subsequently transferred to Eurofins Environment Testing Sweden AB for further analysis.
