**2.8 Sulfur (S)**

In summer, the plants have accumulated higher concentrations of S. The average concentration of S in the plants was 22826.03 μg/g in summer whilst in autumn it was 22749.46 μg/g as presented in **Figure 13**. The uptake of S is also not very pronounced and the average values, do not differ much between the plants measured from the sites as shown in **Figure 13**.
