Dataset description

As part of a federal-state cooperation project, storage tests of PM10 filter samples for benzo(a)pyrene analysis (BaP) were carried out in cooperation with the Office of the Carinthian State Government. It was found that if the samples were frozen to –18 °C, the storage period could be extended to up to one year in glass Petri dishes. Another series of experiments was used to determine the influence of different solvents on the result of BaP analysis. The investigations showed that the solvents acetone:n-hexane, dichloromethane:cyclohexane or toluene, in combination with ultrasonic methods, are suitable for use in BaP analysis. The solvents n-hexane or cyclohexane led to inferior results in the analysis of the reference materials and in a large part of the filters.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
