“…This is in line with already published studies, which covered the potential of surfactants in general as a potential remediation tool for contaminated soils. 14,15,35,36 The pyrethroid formulation used 1 week before the azadirachtin A product did not show any measurable effects, most probably due to its relatively low surfactant content of <5% Tween.…”

“…Surfactants may increase the mobility of SOM-adsorbed lipophilic contaminants, which was already discussed for the direct application of surfactants to soils for remediation purposes or even to support biodegradation . In the field of remediation, DDX and other organic contaminants are mobilized from the soil organic matter which subsequently leads to a depletion. − It was also shown that the influence on the mobility of organic pollutants depends on the type of clay minerals in soil. − …”

Even more than 50 years after the ban of DDT in Germany, farmers are still affected by its persistence in contaminated soils. Depending on the crop cultivated on such soils, this often leads to low-level residues of DDT and its metabolites DDE and DDD ("DDX"), which are perceived as a risk by the food value chain. Pesticide formulations used in modern agriculture commonly contain high levels of surfactants, but so far no open-field studies have evaluated the effects of these treatments on the mobility of lipophilic contaminants, such as DDX. In this field trial, a 1.03 ha section was cultivated with Cucurbita maxima under realistic conditions to monitor the mobility of DDX in low-level contaminated agricultural soils in dependence of common pesticide applications. A typical organic treatment was compared to a conventional protocol. Soil samples were taken before and after each application. Samples from the organic section featured significantly higher extractable DDX contents in soil and water compared to the conventional section. The results show that modern pesticide treatments can have an unforeseen, yet significant influence on the mobilization and, subsequently, on the plant bioavailability of incurred DDX residues depending on the formulation composition.

The practice of incorporating animal manure into soil is supported within the European Circular economy as a possible substitute for mineral fertilizers and will become crucial for the sustainability of agriculture. However, this practice may indirectly contribute to the dissemination of antibiotics, resistance bacteria, and resistance genes. In this study, medicated drinking water and poultry litter samples were obtained from a broiler-chick farm. The obtained poultry litter was incorporated into the soil at the experimental field site. The objectives of this research project were first to develop analytical methods able to quantify fluoroquinolones (FQs) in medicated drinking water, poultry litter, and soil samples by LC–MS; second to study the fate of these FQs in the soil environment after incorporation of poultry litter from flock medicated by enrofloxacin (ENR); and third to screen the occurrence of selected fluoroquinolone resistance encoding genes in poultry litter and soil samples (PCR analysis). FQs were quantified in the broiler farm’s medicated drinking water (41.0 ± 0.3 mg∙L−1 of ENR) and poultry litter (up to 70 mg∙kg−1 of FQs). The persistence of FQs in the soil environment over 112 days was monitored and evaluated (ENR concentrations ranged from 36 μg∙kg−1 to 9 μg∙kg−1 after 100 days). The presence of resistance genes was confirmed in both poultry litter and soil samples, in agreement with the risk assessment for the selection of AMR in soil based on ENR concentrations. This work provides a new, comprehensive perspective on the entry and long-term fate of antimicrobials in the terrestrial environment and their consequences after the incorporation of poultry litter into agricultural fields.

While this is applicable for (expensive) building land as an alternative to removal and extraction, this is not feasible for agricultural soils.…”

Modern Agrochemicals Influence Bioaccumulation of Incurred DDT Soil Residues in Pumpkins – Residue Risk or a Chance for Phytoremediation?

Due to the high persistence of DDT and its metabolites DDE (1-chlor-4-(2, 2-dichlorphenyl-1(4chlorphenyl) ethenyl) benzene) and DDD (1-chlor-4-(2,2-dichlor-1-(4-chlorphenyl) ethyl) benzol) (-DDX‖) against microbial and chemical degradation, still distinct quantities of DDX are found in many soils all over the world [2-5]. The main hot spots are found in Asia [2,3], America [4,5] and southern Africa, while levels in Western Europe [6,7] are comparably low. In combination with the highly lipophilic character (log K ow DDT = 6,91 [8]), DDX remain adsorbed mainly to soil organic matter and therefore, relatively static in upper soil layers. It is however known that lipophilic contaminants adsorbed to the dissolved organic carbon (DOC) fraction of the soil show an increased water solubility and therefore, mobility. This mobility may be significantly influenced by the application of surfactants, which was demonstrated in a number of studies [9-15], where surfactant/ water mixtures were directly applied to soil samples or used to extract soils. Such mixtures are commercially used for the removal of non-aqueous phase liquids (NAPLs) [16] from highlycontaminated soils, e.g. resulting from oil leakages. This process is commonly performed by the Abstract: Although banned more than 50 years ago, residues of first generation organochlorine pesticide residues, such as DDT are still found in agricultural soils all over the world. Phytoremediation is a potential remediation strategy, using plants to remove these residues from the soils. One limiting factor is the low mobility and bioavailability of lipophilic compounds for plants. Soil mobility can be significantly increased by the application of surfactants to the soils. Agrochemicals, in particular crop protection formulations commonly contain major amounts of surfactants as adjuvants, a fact which so far has not been considered an influencing factor for the mobilization of organochlorine contaminants such as DDT. This study evaluated the influence of commonly applied agrochemical products on the bioavailability of DDT and its metabolites in pumpkins in an open-field trial. To compare different typically used products, organic farming pesticides were compared against conventional formulations.
