Data for the paper: Modelling metal uptake by selected vegetables from urban soils in Europe: Uncovering key soil factors using Partial Least Squares Regression (PLS-R)

https://doi.org/10.5878/mpyy-9j29
The dataset comprises geochemical analysis data from 22 soils collected from allotment gardens in urban environments across six cities in Europe, along with chemical analyses of three vegetables cultivated in a greenhouse environment using these soils. The soils exhibit varying degrees of contamination by typical urban metal contaminants; Ba, Cd, Cu, Ni, Pb, and Zn. The record consists of two files, a CSV file containing analysis data, and a PDF document with explanations and descriptions of analysis methods for the parameters in the CSV file.

Data collection Field/Intervention experiment

Mode of collection:

Field/Intervention experiment

Description of the mode of collection:

Three vegetables; lettuce, chard, and carrot, was cultivated in a greenhouse, in the collected soils. Plant parts were harvested, washed, and dried in a drying cabinet at 60 degrees Celsius for 24 hours before chemical analysis. Soil samples were sieved to < 2 mm size. Following this, pH measurement and determination of organic content were conducted using loss-of-ignition (580 degrees Celsius) at Linnaeus University in Kalmar on a subset of the samples. The remaining soil was dried in drying cabinets at 60 degrees Celsius for 24 hours, and then sent to ALS Scandinavia AB in Luleå for chemical analyses. All analysis methods applied to plants and soils are described in the post's PDF document.
