The study found that a microalgae consortium can effectively remove pesticides from water, with chlorpyrifos and cypermethrin showing the best removal efficiency, and a transformation product of chlorpyrifos was identified. Anaerobic digestion was not inhibited by the pesticides, and the removal efficiency of the pesticides in the digestate decreased in the order of chlorpyrifos > cypermethrin > oxadiazon.
Intensive and extensive use of pesticides has contributed to their wide distribution in soil, air, and water. Due to their detrimental effects on non-target organisms, different technologies have been considered for their removal. In this work, three hydrophobic pesticide active compounds, namely, chlorpyrifos, cypermethrin, and oxadiazon, were selected to study the potential for their removal from aqueous media by a microalgae consortium. An abiotic and a killed control (thermally inactivated dead microalgae biomass) were employed to clarify their removal pathways, and pesticide content was quantified in liquid and biomass phases for 7 days. At the final time, total degradation (biodegradation plus photodegradation) contributed to the removal of 55% of oxadiazon, 35% of chlorpyrifos, and 14% of cypermethrin. Furthermore, more than 60% of chlorpyrifos and cypermethrin were removed by sorption onto microalgae biomass. Overall, the three pesticides showed high removal from the liquid phase. O,O-diethyl thiophosphate was identified in the liquid phase as a transformation product of chlorpyrifos formed by microalgae degradation. Phycoremediation was coupled with anaerobic degradation of the microalgae biomass containing the retained pesticides by sorption through biochemical methane potential tests. Anaerobic digestion was not inhibited by the pesticides as verified by methane production yields. The removal efficiency of the pesticides in the digestate was as follows: chlorpyrifos > cypermethrin > oxadiazon. These results highlight the potential of low-cost algal-based systems for the treatment of wastewater or effluents from agrochemical industries. The integration of wastewater treatment with biogas production through anaerobic digestion is a biorefinery approach that facilitates the economic feasibility of the process. (C) 2020 Elsevier B.V.

First study on the presence of plastic additives in loggerhead sea turtles (Caretta caretta) from the Mediterranean Sea

Berta Sala, Aleix Balasch, Ethel Eljarrat, Luis Cardona

Summary: Loggerhead turtles voluntarily ingest floating plastic debris and are chronically exposed to plastic additives. The presence of organophosphate esters (OPEs) in their tissues is mainly from ingestion of plastic debris rather than their prey, leading to biomagnification potential of certain OPEs in turtle muscle compared to their main prey. Regular ingestion of plastic debris and contamination from their prey may explain the significantly higher levels of OPEs in loggerhead turtles than in other marine animals in the western Mediterranean.

Pesticide bioremediation by Trametes versicolor: Application in a fixed-bed reactor, sorption contribution and bioregeneration

Eduardo Beltran-Flores, Montserrat Sarra, Paqui Blanquez

Summary: The study showed that using Trametes versicolor immobilized on Quercus ilex wood chips is an effective method for removing pesticides from agricultural wastewater. The differences in removal efficiency of diuron and bentazon on wood materials are mainly influenced by their affinity for wood. Regenerating pesticide-contaminated wood using T. versicolor in a biopile-like system can achieve high fungal colonization, degradation rate, and degradation yields.

Human exposure to organophosphate esters in water and packed beverages

Julio Fernandez-Arribas, Teresa Moreno, Ethel Eljarrat

Summary: Drinks are a significant source of human exposure to plasticizers like OPEs. This study analyzed OPE levels in various drink samples and found that tap water had higher levels compared to packed water, possibly due to PVC water pipes. Regular cola drinks had the highest OPE concentrations, particularly EHDPP. Although OPE exposure was below safety limits, the potential health risks from regular cola drinks, juice, and tap water should not be ignored, and other exposure routes should also be considered.

A. Peris, R. Baos, A. Martinez, F. Sergio, F. Hiraldo, E. Eljarrat

Summary: Donana National Park (DNP) is a protected area known for its diverse bird species. However, the use of pesticides in the surrounding agricultural practices has led to contamination of the park's bird eggs, with detrimental effects on their health and reproduction. A study conducted over a span of more than twenty years (1999-2021) identified 26 pesticides in the collected bird eggs, including commonly detected organochlorine and newly detected pyrethroid pesticides. The concentrations of these pesticides varied, with some exceeding levels known to be harmful to avian species. The findings call for control measures to limit pesticide use and further investigation into the impact on bird populations in this protected area.
