Environmental impacts of genetically modified crops

Science, Journal Year: 2024, Volume and Issue: 385(6712)

Published: Aug. 29, 2024

Genetically modified (GM) crops have been adopted by some of the world's leading agricultural nations, but full extent their environmental impact remains largely unknown. Although concerns regarding direct effects GM declined, led to indirect changes in practices, including pesticide use, expansion, and cropping patterns, with profound implications. Recent studies paint a nuanced picture these impacts, mixed crop adoption on biodiversity, deforestation, human health that vary trait geographic scale. New or gene-edited different traits would likely impacts.

Glyphosate lessons: is biodegradation of pesticides a harmless process for biodiversity?

Environmental Sciences Europe, Journal Year: 2024, Volume and Issue: 36(1)

Published: March 17, 2024

Abstract The historical perspective on the rapid biodegradation of pesticides as a mitigating factor in environmental risk assessment is reexamined through example glyphosate and its implications for freshwater biodiversity. Commonly employed standardized methods by national agencies assessing predominantly rely single-species tests, overlooking intricate nature ecosystems. Glyphosate, one most widely used marketed purported biodegradability, often perceived relatively innocuous. However, degradation releases phosphorus into environment, inducing trophic state shift water systems towards more eutrophic conditions, consequently affecting quality. These findings highlight cascading ecological repercussions biodegradation, driving proliferation specific aquatic organisms, such picocyanobacteria metaphyton, resulting alteration ecosystem structure dynamics. study explores challenges posed commercial pesticide formulations investigates consequences interactions with anthropogenic factors.

Characterization of Glyphosate Resistance and Degradation Profile of Caballeronia zhejiangensis CEIB S4-3 and Genes Involved in Its Degradation

Microorganisms, Journal Year: 2025, Volume and Issue: 13(3), P. 651 - 651

Herbicides are the most employed pesticides in agriculture worldwide; among them, glyphosate is successful herbicide molecule history. The extensive use of has been related to environmental pollution and toxic effects on non-target organisms. Effective remediation treatment alternatives must be developed reduce presence its adverse effects. Bioremediation using microorganisms proposed as a feasible alternative for treating pollution; due this, identifying characterizing capable biodegrading key task bioremediation polluted sites by this herbicide. This study characterized resistance profile degradation capacity bacterial strain Caballeronia zhejiangensis CEIB S4-3. According results growth inhibition assays agar plates, C. S4-3 can resist exposure high concentrations glyphosate, up 1600 mg/L glyphosate-based (GBH) formulation, 12,000 analytical-grade molecule. In assay liquid media, resisted all evaluated (25–400 mg/L). After 48 h exposure, GBH caused important (>80%) at between 100 400 mg/L, while inhibitions below 15% tested concentrations. Finally, was degrading 60% supplemented culture media (50 mg/L), when used sole carbon source, twelve hours; moreover, also degrade primary metabolite aminomethylphosphonic acid (AMPA). Genomic analysis revealed genes associated with two reported metabolic pathways degradation, sarcosine AMPA pathways. first report metabolism genus strain. from investigation demonstrate that exhibits significant potential biodegradation, suggesting applicability strategies targeting contaminant.

Pesticides affect biota inside and outside agricultural fields due to their intrinsic mode of action. This study investigated whether pesticide active substances (AS) approved for conventional agriculture in Europe differ ecotoxicity from AS organic agriculture. The evaluation was based on official ecotoxicological data surrogate honeybee, bird, earthworm species, which also serve as a reference environmental risk assessments the authorization process.

The continuous discharge of agrochemicals used in intensive agriculture contaminates aquatic systems, harming biota and their processes. Although mobile organisms can avoid exposure by moving to less-affected habitats, capacity be altered pollutant exposure. Populations with a previous disturbance history, which show lower ability respond subsequent stressors, are defined as vulnerable. Therefore, this study investigated the so far unknown escape vulnerable zooplankton population previously exposed contaminated environment. To end, agrochemically driven vulnerability was induced populations Daphnia magna sublethal concentrations glyphosate. Vulnerability verified using starvation test significant differences were observed between control history.

Herbicides are formulated to manage undesired vegetation; however, the potential adverse effects of herbicides on non-target species interest scientific community, regulators, communities, and industry alike. In this study, using glyphosate as an example, use publicly available tools assess risks several ecological receptors was demonstrated. To end, data application rates in California were gathered from 2022 Department Pesticide Regulation (CDPR) report toxicity Ecotoxicology Knowledgebase (ECOTOX) relevant agency reports. Subsequently, U.S. Environmental Protection Agency (EPA) models (BeeREX, T-HERPS, T-REX) used screening level risk honeybees, herpetofauna, birds, mammals. It demonstrated that highest honeybees compared other considered, since rate not anticipated exceed acute chronic levels concern (LOCs) estimated at 8.85×10^{− 6} lbs/A, which lower than minimal 7.70×10^{− 5} lbs/A. comparison, mammals, for LOCs 0.58, 0.53, 0.29 respectively; these between median mean 0.142 0.701 respectively. concluded can be effective during pesticide development understanding various receptors, then inform decision making it relates appropriate mitigation strategies.
