Sorption of four herbicides and a metabolite of indaziflam on a fresh macadamia nut biochar and biochars aged one or two years in soil was characterized. On fresh biochar, the sorption was terbuthylazine (Kd = 595) > indaziflam (Kd = 162) > MCPA (Kd = 7.5) > fluoroethyldiaminotriazine (Kd = 0.26) and nicosulfuron (Kd = 0). Biochar surface area increased with aging attributed to the loss of a su...

An indirect format enzyme-linked immuno-sorbent assay (ELISA) on graphite rods ( 0.8 mm x 20 mm) and, for comparison, on microtiter plates has been developed against terbuthylazine. For this purpose, a series of 2-aminoalkyl-4-chloro-6-terbuthyl-s-triazine-2,6-diamine ELISA haptens with alkyl spacer lengths of 2, 4, 6, and 8 CH2 groups has been synthesized. The graphite rods or the microtiter p...

Abstract. Biocides used in film protection products leaching from facades are known to be a potential threat the environment. This study identifies individual sources and entry pathways small-scale urban area. We investigate emissions of commonly biocides (terbutryn, diuron, octylisothiazolinone – OIT) some their transformation (TPs; diuron-desmethyl, terbumeton, terbuthylazine-2-hydroxy, terbu...

A small hydrological basin (Lerma, NE Spain), transformed from its natural state (steppe) to rain-fed agriculture and recently to irrigation agriculture, has been monitored across four seasons of an agricultural year. The goal of this study was to assess how and whether agricultural activities impacted the nearby freshwater ecosystems via runoff. Specifically, we assessed the toxicity of three ...

The study was focused on the assessment of effects of herbicide preparation Gardoprim Plus Gold 500 SC (terbuthylazine and S-metolachlor as active substances) on haematological and biochemical indices as well as tissue histopathological changes in common carp (Cyprinus carpio L.). Forty eight oneto two-year-old fish were divided into two groups, i.e. 24 fish were treated with 13.0 mg·l-1 of Gar...

The frequency and mass concentrations of 13 herbicide micropollutants (triazines, phenylureas, chloroacetanilides and trifluralin) were investigated during 2014 in surface, ground and drinking waters in the area of the city of Zagreb and its suburbs. Herbicide compounds were accumulated from water by solid-phase extraction using either octadecylsilica or styrene-divinylbenzene sorbent cartridge...

Many countries are now facing the problem of increase in resistant biotypes weeds. The spread herbicide-resistant weeds across agrophytocenoses poses a threat decrease effectiveness use herbicides agricultural fields. In order to develop anti-resistant compositions for protection maize (Zea mays L.) crops, we studied effects interaction and efficiency weed control greenhouse field experiments. ...
