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

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.
