Data on the profile of organic contaminants in the L'Albufera Natural Park (2019-2020). Target and non-target screening.

This article presents a dataset on 71 pesticide levels and the identification of additional synthetic organic chemicals, including pharmaceuticals and industrial compounds, in L'Albufera Natural Park (Valencia, Spain). Sampling was conducted during May-June (spring) and end of September-October (autumn) 2019, timed to the rice cultivation cycle, the region's main agricultural activity. A total of 130 samples (100 water and 30 sediments) were collected from 51 strategically selected sites, including rivers, irrigation channels, Albufera Lake, and Mediterranean outlets, utilizing a combination of targeted and non-targeted screening (NTS) methods. The dataset encompasses physical-chemical parameters for both spring and autumn seasons. Advanced analytical techniques, such as high-resolution mass spectrometry (HRMS), were employed to detect contaminants beyond traditional methods, providing critical insights for environmental management and policy development. The findings contribute to addressing gaps in knowledge regarding contaminants of emerging concern (CECs) and their distribution across different environmental compartments. These data supplement the findings of the research article "Fingerprinting of Emerging Contaminants in L'Albufera Natural Park (Valencia, Spain): Implications for Wetland Ecosystem Health".
