Abstract

Pesticides and metals are often used in agriculture and are therefore often simultaneously discharged to nearby estuarine and marine areas. The effects of this organic-inorganic chemical mixture on food quality of aquatic organisms are currently unknown. In this study we test if a mixture of copper (inorganic) and the herbicide Primextra® Gold TZ (organic) affects the quality of the diatom Thalassiosira weissflogii and the copepod Acartia tonsa – two key species that fuel the local food-web. We quantified quality (i.e. energy content as food for the next trophic level) in terms of fatty acids, proteins and thiobarbituric acid reacting substances. We found non-additive effects (positive and negative) of the metal-herbicide mixture on the diatom and copepod species. In general, nutritionally important biochemical parameters of Acartia tonsa were most sensitive to the chemical stressors.

Funding

This work was funded through the Erasmus Mundus MARES Joint Doctorate programme ( FPA 2011-0016 ) ( www.mares-eu.org ). This study had also the support of Portuguese Foundation for Science and Technology (FCT, Portugal), through the strategic project UID/MAR/04292/2013 , granted to MARE, and UID/AMB//50017/2013 , granted to CESAM. A. M. M. Gonçalves and Sérgio M. Marques also thank FCT for financial support through the post-doctoral grants SFRH/BPD/97210/2013 and SFRH/BPD/112803/2015 respectively, co-funded by the Human Potential Operational Programme (National Strategic Reference Framework 2007–2013 and 2014–2020), European Social Fund (EU) and the program POPH/FSE. The FA analyses were supported by FWO-Flanders (research grant 1523814N ) and by the Special Research Fund of Ghent University (BOF-UGent) in the form of the starting grant ‘Energy transfer at the basis of marine food webs in a changing world’, both awarded to M. De Troch.
