Dataset on trace elements and legacy and emerging organic contaminants concentrations in sediments cores in L’Albufera Natural Park (Valencia, East of Spain): Association with “in-deep” sediment characteristics and risk assessment to the aquatic biota.

Description

The dataset presents information on the vertical distribution of contaminants, covering legacy heavy metals, emerging contaminants like pharmaceuticals, personal care products, and pesticides, as well as persistent organic pollutants in sediment cores from two areas (North and South) of L'Albufera lake. It includes 14C-data for organic matter and seashells, along with physico-chemical analyses of sediment characteristics at various depth levels. Additionally, an ecological risk assessment is conducted to determine potential toxicity in the surface sediment layers.

Steps to reproduce

The data were collected for six sediment cores. Three of the cores are from the Northern zone at the coordinates 39°20'39.10"N 0°21'29.60"W and the other 3 from the Southern zone at the coordinates 39°19'16.50"N 0°21'46.00"W. The sediment cores of approximately 70 cm deep sediments were frozen, cut into 10 cm portions and the following parameters were determined for each portion: age of the sediment, age of the shells present, texture, organic carbon (Corg), inorganic carbon (IC), total nitrogen (TN), total sulphur (TS), heavy metals (HMs) and metalloids, polycyclic aromatic hydrocarbons (PAHs), perfluoroalkyl substances (PFAS), organophosphorus flame retardants (OPFRs), pesticides and pharmaceutical and personal care products (PPCPs).
