A new method for determination of pyrethroids, pyrethrins, and piperonyl butoxide (PBO) by high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS) was developed for aquatic sediments. The method detection limits for pyrethroids (15 compounds), pyrethrins, and PBO ranged from 0.16 to 1.50 ng/g sediment, which was suitable for detecting these chemicals at environmentally ...

Length-weight relationship and condition factor were estimated in seven fish species, including Barbus cyri, Capoeta gracilis, Alburnoides eichwaldii, Pseudorasbora parva, Ponticola cyrius, Cobitis keyvani and Acanthalburnus microlepis from Shahrbijar River, Guilan Province, Iran. A total of 416 specimens ranging from 18 to 135 mm in total length and from 0.06 to 19.25 g in total weight were co...

a biofilm sequencing batch reactor with a volume of 1.42 m3, nylon nets providing a 4,140 m2/m3 support area for biofilms and an automated operation with 8 hour cycles was studied. the duration of the experiment was 135 days. removal efficiencies e≥ 80% were obtained for carbonaceous matter, producing an effluent with 31±26.8 mg/l of filtered cod, 7±3.6 mg/l of bod5 and 12±3.2 mg/l of toc. the ...

Plants growable in rangelands play an important role in the feeding of ruminants; hence, the nutritive value of four plants (Falcaria vulgaris, Malva neglecta, Chenopodium album, and Polygonum aviculare) was determined by different laboratory methods. The plant samples were randomly collected in vegetative phase from different rangelands of Torbat-e Jam, Iran in spring 2018. The range of dry ma...
