ISSN:
0045-6535
Subject:
ammonium chloride; bioavailability; clay; clay fraction; fractionation; guidelines; particle size; radioactivity; sand; silt; sodium
Abstract:
... In order to investigate the influence of differently sized particle fractions on the fate of ionic chemicals in water-sediment systems, we performed simulation studies following OECD guideline 308. We used ¹⁴C-labelled anionic (4-n-dodecylbenzenesulfonic acid sodium salt, ‘¹⁴C-DS⁻’), cationic (4-n-dodecylbenzyltrimethyl ammonium chloride, ‘¹⁴C-DA⁺‘) and non-ionic (4-n-dodecylphenol, ‘¹⁴C-DP’) orga ...

Subject:
Lactuca sativa; adsorbents; adsorption; agricultural soils; ammonium chloride; aqueous solutions; bioavailability; desorption; dolomite; fertilizers; microorganisms; models; phosphates; phytotoxicity; wastes; water treatment
Abstract:
... Desorption is a method that contributes to two important aspects for the sustainability of the water treatments that involve adsorption processes: a) the regeneration of the adsorbent making it reusable in several efficient cycles and, b) the recovery of the adsorbate. In previous studies, it was shown that dolomite constituted an efficient adsorbent of phosphates from aqueous solutions. Once the ...

Subject:
Brassica rapa subsp. chinensis; ammonium chloride; arsenic; bioavailability; correlation; greenhouse experimentation; heavy metals; hydrochloric acid; iron oxides; models; pH; soil properties; soil solution; China
Abstract:
... Several predictive models and methods have been used for heavy metals bioavailability, but there is no universally accepted approach in evaluating the bioavailability of arsenic (As) in soil. The technique of diffusive gradients in thin-films (DGT) is a promising tool, but there is a considerable debate with respect to its suitability. The DGT method was compared with other traditional chemical ex ...

Abstract:
... Cationic surfactants such as benzalkonium chlorides (BACs) are used extensively as biocides in hospitals, food processing industries, and personal care products. BACs have the potential to reach the rooting zone of crop plants and BACs might thereby enter the food chain. The two most commonly used BACs, benzyl dimethyl dodecyl ammonium chloride (BDDA) and benzyl dimethyl tetradecyl ammonium chlori ...

Subject:
Triticum aestivum; ammonium chloride; ammonium sulfate; bioavailability; burning; flowering; foliar application; grain yield; leaves; nitrogen; nitrogen content; phytic acid; urea; wheat; zinc; zinc sulfate
Abstract:
... It is still unclear if different sources of nitrogen (N) can variably influence grain accumulation of zinc (Zn), N, and phytate. We tested foliar treatments of 0 or 0.25% Zn as zinc sulfate in combination with 0 or 1% N as ammonium chloride, ammonium sulfate or urea sprayed on field-grown-wheat (Triticum aestivum L.) foliage at anthesis and 10 days later. Leaf burning caused by ammonium chloride s ...

Abstract:
... Phosphorus (P) immobilization by inactivating agents in the sediment of eutrophic lakes to reduce immediately available P in lake water is often crucial for mitigating nuisance eutrophication symptoms, such as cyanobacterial blooms. Macrophytes and phytoplankton, however, can directly utilize P from the sediment for growth. Accordingly, a comprehensive analysis of the P bioavailability in lake sed ...

Abstract:
... Plant ash derived from fire plays an important role in nutrient balance and cycling in ecosystems. Factors that determine the composition and availability of ash nutrients include fire intensity (burn temperature and duration), plant species, habitat nutrient enrichment, and leaf type (live or dead leaf). We used laboratory simulation methods to evaluate temperature effects on nutrient composition ...
