This paper presents the method of obtaining poly(propylene) (PP) nonwoven fabrics with antimicrobial properties, using Alafosfalin as the nonwoven modifying agent. Alafosfalin, namely L-alanyl-L-1-aminoethylphosphonic acid, presents representative P-terminal phosphonodipeptide, which possesses a strong, broad spectrum of antimicrobial properties. The analysis of these biofunctionalized nonwoven fabrics processed by the melt-blown technique, included: scanning electron microscopy (SEM), UV/Vis transmittance, FTIR spectrometry, and air permeability. The nonwovens were subjected to microbial activity tests against colonies of Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria. Results indicate that the described nonwovens can be successfully used as an antibacterial material.

“…glyphosate becomes 559 less bioavailable) (Borggaard and Gimsing, 2008). AMPA is water soluble and degrades more 560 slowly than glyphosate (Grunewald et al, 2001), with a reported soil half-life that ranges from 561 60 -240 days (Grandcoin et al, 2017). The low frequency of detection and generally low 562 concentration of AMPA in our water and sediment samples reveal that decomposition of 563 glyphosate by the AMPA pathway is relatively slow in our system, or that AMPA and 564 glyphosate are rapidly flushed into the waters of the adjacent bays and diluted below detection 565 limits.…”

When an invasive wetland grass degrades a Ramsar wetland and Important Bird Area, decisive management action is called for. To limit the extent and spread of European Phragmites australis, the Ontario government began the first, large-scale application of glyphosate (Roundup Custom®) over standing water to control an invasive species in Canadian history. Between 2016 and 2018, over 1000 ha of marsh were treated. To assess the risk this herbicide presented to aquatic biota, we measured the concentration of glyphosate, its primary breakdown product aminomethylphosphonic acid (AMPA), and the alcohol ethoxylate-based adjuvant Aquasurf® in water and sediments in areas of the highest exposure risk and up to 150 m into adjacent bays. We never detected glyphosate or AMPA at concentrations exceeding thresholds of toxicological concern. The maximum observed concentration of glyphosate in water was 0.320 ppm, occurring within 24 hr of application. The maximum glyphosate concentration in sediment was 0.250 ppm, occurring within 30 days of application. AMPA was detectable in water and sediment, indicating microbial breakdown of glyphosate in the marsh, but at low concentrations (maxwater = 0.025 ppm, maxsed = 0.012 ppm). The maximum distance from the point of application at which glyphosate was detected in the water was 100 m, vs. 0 m for AMPA. Concentrations in water returned to pre-treatment levels (<DL) within 20-30 days of application. In sediment, glyphosate residue persisted above detection limits (>0.005 ppm) for over one year but less than two years. Concentrations of alcohol ethoxylates were variable in space and time, following a pattern that could not be attributed to Aquasurf® application. The direct, over-water application of Roundup Custom® with Aquasurf® to control invasive P. australis does not pose a toxicological risk to aquatic biota.HighlightsGlyphosate-based herbicide was applied directly to >1000 ha of marsh to control invasive P. australisGlyphosate and AMPA did not reach levels of toxicological concern for aquatic biotaAquasurf® exceedances were observed but could not be attributed to P. australis control activityGlyphosate, AMPA, and Aquasurf® dispersed no more than 100 m from the point of applicationGlyphosate, AMPA and Aquasurf® in water returned to baseline levels within 30 days of applicationGlyphosate, AMPA and Aquasurf® in sediment returned to baseline levels within 2 years

“…The maximum admissible level of GPS in drinking water is 700 µg L −1 according to water quality standards dictated by the US Environmental Protection Agency (EPA) [20]. In the European Union, concentrations for any single pesticide are not to exceed 0.1 µg L −1 , while total pesticide concentrations are not to exceed 0.5 µg L −1 [21]. The different water quality standards are attributed to varying policies.…”

Glyphosate (N-(phosphonomethyl) glycine) (GPS) is currently the most commonly used herbicide worldwide, and is generally considered as immobile in soils. However, numerous reports of the environmental occurrence of the herbicide coupled with recent evidence of human toxicity necessitate further investigation as to the behavior of GPS in the soil environment. Batch sorption studies along with miscible displacement experiments were carried out in order to assess the mobility of GPS in two Louisiana agricultural soils; Commerce silt loam and Sharkey clay. Batch results indicated a high affinity of both soils for solvated GPS, with greater affinity observed by the Sharkey soil. GPS sorption in the Commerce soil was most likely facilitated by the presence of amorphous Fe and Al oxides, whereas the high cation exchange capacity of the Sharkey soil likely allows for GPS complexation with surface exchangeable poly-valent cations. Miscible displacement studies indicate that GPS mobility is highly limited in both soils, with 3% and 2% of the applied herbicide mass recovered in the effluent solution from the Commerce and Sharkey soils, respectively. A two-site multi-reaction transport model (MRTM) adequately described GPS breakthrough from both soils and outperformed linear modeling efforts using CXTFIT. Analysis of extracted herbicide residues suggests that the primary metabolite of GPS, aminomethylphosphonic acid (AMPA), is more mobile in both soils, although both compounds are strongly retained.
