Special Issue Information

Dear Colleagues,

The use of pesticides and biocides plays a pivotal role in agriculture, public health, and industrial applications. However, their presence in food, feed, animals, and humans poses significant challenges to health and environmental safety. Plant production systems worldwide are working to meet diverse and growing needs of humankind while addressing challenges such as climate change and biodiversity loss. At the same time, there is an increasing demand for the transition from conventional pesticides to low-risk, sustainable plant protection products.

Despite strong political goals at the global level—including the United Nations 2030 Agenda for Sustainable Development, the Farm to Fork Strategy, the Biodiversity Strategy, REFIT and the Chemicals Strategy for Sustainability—inefficiencies in implementation and regulatory complexities remain significant barriers to achieving desired outcomes for both environmental and human health.

This Special Issue aims to address novel challenges in the monitoring, risk assessment and management of pesticides and biocides, within the framework of the One Health approach, which emphasizes the interrelation of human, animal, and environmental health. Contributions are invited in the following areas:

  • innovative analytical methods for detecting pesticides and biocides across manifold matrices, including food, feed, animals, human biomonitoring, environmental samples, and indicator species;
  • risk assessment and toxicological studies that explore their impacts (e.g., endocrine disruption, carcinogenicity and effects on pollinators);
  • research on new regulatory requirements for the renewal and approval of bioactive substances.

By uniting multidisciplinary perspectives, this Issue seeks to foster scientific advancements and policy innovations that support sustainable and health-conscious chemical management.

Do Isopropylammonium Glyphosate and LiCl Impact the Spore Diversity and Functions of Aquatic Fungi Involved in Plant Litter Decomposition in Streams?

Glyphosate based-herbicides are stressors of great concern because they can impact aquatic ecosystems. Similarly, lithium, a metal, is currently of concern because of its increasing use worldwide. Because glyphosate-based herbicides and lithium might co-occur in aquatic environments, there is a need to assess their impacts on aquatic organisms, such as aquatic fungi, as they play a key role in plant litter decomposition in streams. Microcosm assays were used to examine the effects of lithium and the herbicide isopropylammonium glyphosate (IPAG), alone or in mixtures, on microbial leaf mass loss, total fungal sporulation and biomass production. IPAG (alone and combined with LiCl) neither affected plant litter decomposition nor fungal biomass production, but boosted total fungal sporulation. Dimorphospora foliicola, the most tolerant species among the twelfth leaf inhabitant fungal species, is the major contributor to total fungal sporulation. IPAG interacts with LiCl in the total fungal sporulation and sporulation of D. foliicola, A. tetracladia, and F. curvula, indicating a species dependent-effect. IPAG alone or combined with LiCl greatly decreased the diversity of spores, as did as LiCl alone, but to a lesser extent. Finally, aquatic fungal communities reveal redundancy and resiliency to IPAG and LiCL, maintaining the health of aquatic ecosystems. Full article

Abstract
Fluorinated pyrethroids, such as cyfluthrin and cyhalothrin, are more effective insecticides due to their enhanced stability and lipophilicity. However, they pose greater risks to non-target organisms. Their persistence in the environment and accumulation in tissues can lead to increased toxicity and ecological concerns. [...] Read more.
Fluorinated pyrethroids, such as cyfluthrin and cyhalothrin, are more effective insecticides due to their enhanced stability and lipophilicity. However, they pose greater risks to non-target organisms. Their persistence in the environment and accumulation in tissues can lead to increased toxicity and ecological concerns. This study investigates the biodegradation of the fluorinated pyrethroids β-cyfluthrin (BCF) and λ-cyhalothrin (LCH) using a newly isolated Bacillus sp. MFK14 from a garden soil microbial consortium. Initial screening using 19F NMR analysis showed that the microbial consortium degraded both pyrethroids, leading to the isolation of Bacillus sp. MFK14. Subsequent GC-MS analysis revealed various degradation intermediates in both pyrethroids after incubation with Bacillus sp. MFK14. Notably, Bacillus sp. MFK14 completely degraded β-cyfluthrin and λ-cyhalothrin within 48 h at 30 °C. Fluoride ions from β-cyfluthrin and trifluoroacetic acid (TFA) from λ-cyhalothrin were detected as the end-products by 19F NMR analysis of the aqueous fraction. The pathway of the degradation was proposed for both the pyrethroids indicating shared biodegradation pathways despite different fluorinations. Inhibition studies with 1-ABT suggested the involvement of bacterial cytochrome P450 (CYP) enzymes in their biodegradation. The CYPome of Bacillus sp. MFK14 includes 23 CYP variants that showed significant sequence similarity to known bacterial CYPs, suggesting potential roles in pyrethroid biodegradation and environmental persistence. These findings highlight the potential for bioremediation of fluorinated pesticides, offering an environmentally sustainable approach to mitigate their ecological impact. Full article
