In the title molecular salt, C(7)H(14)N(5)O(+)·Cl(-) (the HCl salt of the oxo derivative of the triazine herbicide simazine), the cation and anion are linked by N-H⋯Cl hydrogen bonds. The chloride ion is also involved in a close electrostatic inter-action with an inversion-related triazine ring [Cl⋯centroid distance = 3.201 (1) Å]. A π-π inter-action having a centroid⋯centroid distance of 3.456...

Arthrobacter aurescens strain TC1 was isolated without enrichment by plating atrazine-contaminated soil directly onto atrazine-clearing plates. A. aurescens TC1 grew in liquid medium with atrazine as the sole source of nitrogen, carbon, and energy, consuming up to 3,000 mg of atrazine per liter. A. aurescens TC1 is metabolically diverse and grew on a wider range of s-triazine compounds than any...

The aim of the present work was to determine the concentration levels, as well as accumulation and magnification coefficients, of triazine derivatives in herring gulls and Baltic grey seals 11 years after a ban on their use in the EU and eight after their exclusion in Poland. Dead birds were collected in the coastal zone of the Gulf of Gdansk in the years 2010-2012. The grey seals, on the other...

The cell surface interaction between bacterial lipopolysaccharide (LPS), Toll-like receptor 4 (TLR4) and MD-2 is central to bacterial sepsis syndromes and wound healing. We have shown that a generation (G) 3.5 polyamidoamine (PAMAM) dendrimer that was partially glycosylated with glucosamine inhibits TLR4-MD-2-LPS induced inflammation in a rabbit model of tissue scaring. However, it was a mixtur...

The degradation of atrazine [2-chloro-4-(ethylamino)-6-isopropylamino-1,3,5-triazine], deethylatrazine [DEA; 2-amino-4-chloro-6-(isopropylamino)-1,3,5-triazine], and deisopropylatrazine [DIA; 2-amino-4-chloro-6-(ethylamino)-1,3,5-triazine] was assessed under limited oxygen conditions using in situ microcosms. Denitrification was induced in a shallow sand and gravel aquifer to measure the potent...

The asymmetric unit of the title complex, {[Cd(C(9)H(7)N(3)O(6)S(3))(C(12)H(8)N(2))]·0.42H(2)O}(n), contains a Cd(II) atom, one doubly deprotonated 2,2',2''-[1,3,5-triazine-2,4,6-triyltris(sulfanediyl)]triacetic acid ligand (HTTTA(2-)), a 1,10-phenanthroline (phen) ligand and a fractionally occupied water mol-ecule [site occupancy = 0.421 (15)]. The Cd(II) atom is six-coordinated within a disto...

The polyguanamines were prepared by the polymerization of bis[N-(2-anilino-4-chloro-1,3,5-triazine)yl]-4,4’-oxydianiline (Bis(ACT)) with α,ω-alkylene diamines such as 1,12-diaminododecane, 1,10-diaminodecane and 1,8-diaminooctane. NMR analysis Bis(ACT) resulting showed that hydrogen bonds cause between triazine adjacent anilino units. have good solubility in typical organic solvent. Temperature...

Simaaine, diuron, and bromacil are the most frequently detected currently registered pesticides in California groundwater. These herbicides bave been used for several decades in Fresno and ‘Mare counties, California; however, previous data are inadequate to determine whether the detections are a result of recent or historical applications (i.e., within the hut decade, or 2&3tl yr ago). Chlorofl...

During the reaction between 1,3,5-tris(2-hydroxyethyl)hexahydro-s-triazine and hydrogen sulphide, the principle by-product is the organic sulphide 5-(2-hydroxyethyl)dithiazine. It can be determined by a novel, portable, field-capable ion mobility spectrometry method described herein and enables the "degree spent" to be determined. Dependant upon the level of carbon dioxide in the produced gas, ...

BACKGROUND Enhanced atrazine degradation has been observed in agricultural soils from around the globe. Soils exhibiting enhanced atrazine degradation may be cross-adapted with other s-triazine herbicides, thereby reducing their control of sensitive weed species. The aims of this study were (1) to determine the field persistence of simazine in atrazine-adapted and non-adapted soils, (2) to comp...
