“…Orthophosphate (P) was analysed on a spectrophotometer using the ascorbic acid method (APHA 4500‐P E; APHA 2005). The herbicide 2,4‐D and the insecticide fipronil and its degradation products fipronil sulfone and fipronil sulfide were analysed respectively in LC–MS/MS and SPE‐on line‐LC–MS/MS following Goulart et al (2020). Phytoplankton standing crop was measured in situ weekly using an Aquafluor Handheld Fluorometer with in vivo chlorophyll a and phycocyanin channels (Turner Designs).…”

1. Sustainable intensification may depend on associating precision farming with the harnessing of ecological principles in crop fields, and integrating farms and nonfarmed land in productive landscapes. Small wetlands could play an important role in both pursuits for having high per-unit-area rates of element cycling and species richness while deeply penetrating crop fields. However, their potential for ecosystem service provisioning is unlikely to be met if land management intensification promotes ecosystem destabilization in biomass production.2. We tested the consequences of land use intensification on various dimensions of freshwater ecosystem stability by means of a large-scale field experiment converting extensive pastures to intensive pastures and sugarcane plantations in Southeastern Brazil. Nested within experimental plots were 4000 L mesocosms simulating ponds and puddles commonly found in productive landscapes.Mesocosms were monitored for basic physico-chemical parameters, nutrients, pesticides, phytoplankton standing crop, and the spontaneously colonizing biodiversity.3. Despite severe environmental change, the stability of sugarcane communities was no different from that of extensive and intensive pastures. This occurred because the local extinction of a sensitive top dragonfly predator following the application of vinasse and insecticide was compensated by colonization of a suite of more tolerant invertebrate mesopredators such as beetles and bugs. Community stability tended to increase with biomass asynchrony and species richness, evidencing a portfolio effect of biodiversity. Unfortunately, the species richness necessary to

“…The water quality parameters (temperature, dissolved oxygen (DO), pH, electrical conductivity (EC), and turbidity) were monitored using a multiparameter probe (Model YSI Pro DSS). The determination of the 2,4-D concentrations followed the methodology described by Goulart et al (2020). The analyses were performed through Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS) using Agilent 1200 chromatography equipment coupled to a Triple Quadrupole mass spectrometer with electrospray ionization (ESI) (Agilent 6410) (Agilent Technologies-Santa Clara, USA).…”

“…Method validation was performed following the National Institute for Metrological Standardization and Industrial Quality (Inmetro) (Inmetro 2018) and the guidelines of the National Health Surveillance Agency (Anvisa) (Brazil 2017). The figures of merit evaluated were linearity, the limit of detection (LOD), the limit of quantification (LOQ), trueness, precision, and matrix effect (details further described in Goulart et al 2020).…”

Pesticides can cause harmful effects to aquatic communities, even at concentrations below the threshold limit established as guidelines for the water bodies by environmental agencies. In this research, an input of the herbicide 2,4-dichlorophenoxyacetic acid (i.e., 2,4-D) was simulated under controlled conditions in a 500-m-long reach of a first-order tropical stream in Southeastern Brazil. Two water samplings at eight stations investigated the stream longitudinal contamination profile. The ecotoxicological effects were analyzed using Eruca sativa L. seed germination assays and the acute and chronic toxicity tests with the neotropical cladoceran Ceriodaphnia silvestrii. Physicochemical parameters of water quality were evaluated to characterize the study area and quantify 2,4-D concentrations along the stream to assess pesticide retention. The 2,4-D concentration was reduced by approximately 50% downstream in the samplings, indicating that the herbicide was retained along the stream. Moreover, C. silvestrii reproduction in long-term assays decreased approximately 50% in the stations with higher concentrations of 2,4-D than the laboratory control. After contamination, E. sativa L. showed a lower average root growth (1.0 cm), statistically different from the control (2.2 cm). On the other hand, similar growth values were obtained among the background and the most downstream stations. Our study highlighted the relevance of reviewing and updating herbicide guidelines and criteria to prevent possible ecological risks.

“…Traditionally, methods based on large-scale instruments for detecting 2,4-D mainly include high performance liquid chromatography, 8,9 gas chromatography, 10,11 and mass spectrometry. 12,13 Although these methods provide satisfactory and accurate results, they come with certain limitations such as high cost, complex pretreatment, time-consuming procedures, and the need for expertise to obtain accurate results. Therefore, they are not suitable for rapid on-site detection and screening samples in large numbers.…”
