Sulfur in bladder wrack from the Sylt-Römö-Watt
Increasing sulfur levels until the early 2000s
Sulfur is an essential element for all organisms. It is not bioaccumulated. In contaminated environments, however, sulfur levels in plants may be elevated.
In bladder wrack from the Sylt-Römö-Watt sulfur levels increased between the mid 1980s and the early 2000s. This was probably a result of increased emissions from industry and traffic. Thereafter improved emission protection obviously prevented further increases in environmental sulfur.
Routine sampling of bladder wrack was discontinued in 2013.
