Speciation of Elements via a Sequential Extraction Procedure in Municipal Wastewater Biosolids from Three Rural WWTP in East Texas (USA)

In this data article, the bioavailability of elements in municipal wastewater sludge (also known as biosolids) in samples collected from three treatment plants in East Texas, USA was evaluated. Although detailed speciation of the metals were assessed by using inductively coupled plasma optical spectroscopy (ICP-OES), and were discussed in the research article titled “Evaluating bioavailability of elements in municipal wastewater sludge (Biosolids) from three rural wastewater treatment plants in East Texas (USA) by a sequential extraction procedure” [1], this report presents the absolute raw concentrations and fractionations of the 26 metals from the biosolids (Nacogdoches Wastewater Sludge, Lufkin Wastewater Sludge, and Neches Compost sludge; NWWS, LWWS, NCS) produced from three wastewater treatments plants in East Texas. This data is important and useful for understanding the bioavailability of each of the elements in biosolids generated from activated wastewater treatment plants.
