“…However, in order to understand the resultant risks to environment and population health requires improvement in existing knowledge with regards to the fate of herbicides residues in ambient water bodies. The ability of these compounds to accumulate in the environment and their toxicity to aquatic lives, humans, and wildlife is a concern (Amweg et al, 2006;Parsons et al, 2009;Buah-Kwofie and Humphries, 2017;Gama et al, 2017;Morales et al, 2017).…”

Purpose: In recreational water bodies, herbicides are widely used for controlling unwanted weeds, and impacts of herbicide residues on health risks to aquatic ecosystem is a serious concern. This study was aimed to improve the existing understanding of the deposition of herbicides from water column to bed sediment and leachate of herbicides from bed sediment to water column. We investigated the attachment of two herbicides with sediment and release from sediment: (1) Glyphosate; and (2) Fluridone. The goal of this study was to determine the deposition and release of Glyphosate and Fluridone in bed sediment of the Sacramento-San Joaquin River Delta.Materials and Methods: Field sampling was performed to collect water and sediment samples from Sacramento-San Joaquin River Delta. Bottom dredge sampler was used for collecting sediment samples and horizontal water bottle sampler was used for collecting water samples. A series of experiments were conducted to determine the attachment and release of Fluridone and Glyphosate from sediment at a different level of initial concentrations. For analyzing Fluridone and Glyphosate in sediment leachate and water, samples were processed using enzyme-linked immunosorbent assay (ELISA) based method.Results and Discussion: Observations showed that proportions of Glyphosate concentrations in water were higher than Fluridone concentrations in water, when both herbicides were inoculated in water in same quantity. On the contrary, the concentrations of Fluridone in sediment-bound leachate were higher than Glyphosate concentrations in sediment-bound leachate, regardless of the initial concentrations. Fluridone and Glyphosate concentrations in water column samples differed significantly (p < 0.05) over the time even initial concentrations of these herbicides were kept similar, which indicates that Fluridone interaction with water column was considerably different than the interaction of Glyphosate with the water column. Pandey et al. Herbicide Concentration in Water and Sediment LeachateConclusions: Bed sediment can be an important sink and source for release of Fluridone and Glyphosate from bed sediment to the water column of an ambient water body. Significant concentrations of herbicides were deposited in bed sediment of Sacramento-San Joaquin Delta, and eventually the high concentrations of herbicides were observed in sediment leachate. Improved understanding of this important release pathway can provide much needed information to adequately address the impacts of particle attached herbicides on aquatic and ecological environment of a water body.Keywords: fluridone and glyphosate in ambient water, particle attached herbicides, herbicides leachate from sediment, sediment and water column interaction, deposition and resuspension

“…With the same focus, Leyva-Morales et al (2017) assessed the quality of river water from central Sinaloa (Humaya, Tamazula and Culiacan rivers) by monitoring residual pesticides. Their results showed that the following chemicals were present: lindane (0.0041-0.0104μg/L), endosulfan (0.0198-0.03601μg/L), heptachlor, dichlorodiphenyltrichloroethane (0.0525μg/L), diazinon (0.0211-0.0403μg/L), chlorpyrifos, methyl parathion, cyromazine (0.1961μg/L), permethrin (0.2351μg/L), ethion, carbofenothion, lambda cyhalotrine, pyrimicarb, aldrin (0.0099-0.1023μg/ L) and malathion.…”

Over the past two decades, the presence of so-called emerging contaminants in various environmental compartments around the world, such as water, sediments, soils and atmosphere, and in a wide variety of consumer products has become a major concern for society, public health authorities, industry (namely food industry and water sector) and the agricultural sector. Some of these substances are endocrine disruptors and others are proven carcinogens and mutagens. In particular,

“…In Costa Rica, pesticide residues have been detected in various geographical regions of the country, including the Caribbean [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ], the northern zone [ 12 ], the North Pacific [ 13 , 14 , 15 ], the South Pacific [ 16 ], and the horticultural areas of Pacayas and Zarcero in the Central Volcanic Mountain Range [ 17 , 18 ]. In the last 10 years, Cornejo et al [ 19 , 20 ] also detected several pesticide residues in Panama, Barizon et al [ 21 ] in Brazil, Hernández et al [ 22 ] in Colombia, Deknock et al [ 23 ] in Ecuador, Leyva Morales et al [ 24 ] in Mexico, and Cárdenas et al [ 25 ] in Venezuela.…”

Neotropical ecosystems are highly biodiverse; however, the excessive use of pesticides has polluted freshwaters, with deleterious effects on aquatic biota. This study aims to analyze concentrations of active ingredients (a.i) of pesticides and the risks posed to freshwater Neotropical ecosystems. We compiled information from 1036 superficial water samples taken in Costa Rica between 2009 and 2019. We calculated the detection frequency for 85 a.i. and compared the concentrations with international regulations. The most frequently detected pesticides were diuron, ametryn, pyrimethanil, flutolanil, diazinon, azoxystrobin, buprofezin, and epoxiconazole, with presence in >20% of the samples. We observed 32 pesticides with concentrations that exceeded international regulations, and the ecological risk to aquatic biota (assessed using the multi-substance potentially affected fraction model (msPAF)) revealed that 5% and 13% of the samples from Costa Rica pose a high or moderate acute risk, especially to primary producers and arthropods. Other Neotropical countries are experiencing the same trend with high loads of pesticides and consequent high risk to aquatic ecosystems. This information is highly valuable for authorities dealing with prospective and retrospective risk assessments for regulatory decisions in tropical countries. At the same time, this study highlights the need for systematic pesticide residue monitoring of fresh waters in the Neotropical region.
