“…The method that was developed was based on the method reported in Eyring et al, but improvements were made by decreasing preparation and instrument time [4]. The decrease in instrument time was achieved by decreasing the number of injections for each extract from two to one.…”

“…Therefore, the modified WAHSPE method excels exactly where QuEChERS and SweEt fall short. Furthermore, the improvement of the WAHSPE procedure from our previous work [4] allows for increased sample throughput.…”

“…Although QuEChERS and SweEt are widely used methods and generally perform well, some analytes, such as organochlorine pesticides and other nonpolar pesticides, have low recoveries when extracted from lipid-rich samples [6]. We previously developed a method, "water-acetonitrile-heptane-solid-phase-extraction" (WAHSPE), that effectively addressed this problem [4]. However, for the analysis of pesticides in high-fat fish feed, the WAHSPE method requires multiple injections of each sample.…”

“…Analyte recoveries were typically in the range of 70-120% with relative standard deviations below 20%. [4]. This article aims to further develop the WAHSPE method by minimizing the time from sample preparation to final result, while still obtaining good recovery and detection of highly polar and nonpolar pesticides in a lipid-rich matrix, thereby providing a more generic alternative to the QuEChERS and SweEt methods.…”

Animal feed is typically plant-based and can contain pesticide residues. Methods for testing food and feed samples, such as the Quick Easy Cheap Effective Rugged Safe (QuEChERS) method or the Swedish Ethyl Acetate (SweEt) method, successfully extract many pesticide residues. However, nonpolar pesticides, such as organochlorine pesticides, show poor recovery when extracted from lipid-rich samples. The previously developed water-acetonitrile-heptane-solid-phase-extraction (WAHSPE) method shows better recoveries for the nonpolar pesticides but requires two injections per sample and per instrument. Here, we present a modified version of the WAHSPE method for pesticides in fish feed using one injection per sample and per instrument. Of the 184 pesticides tested, 179 met the European Union Legislation’s validation criteria at a spike level of 50 μg/kg, showing recoveries between 70 and 120% and a relative standard deviation (RSD) below 20%. Organochlorine pesticides accounted for 14 of the tested compounds.

The treated distillate aromatic extract (TDAE) is widely used in tread compounds. However, polycyclic aromatic hydrocarbons (PAHs) contained in TDAE is serious harm to the environment and human. In this paper, liquid polybutadiene (LPB) of different brands was used to replace TDAE to plasticize solution polymerized styrene-butadiene rubber/cis-1,4-polybutadiene rubber (SSBR/BR). The effects of liquid polybutadiene instead of TDAE on crosslinking network and mechanical properties of matrix rubber were studied. LPB could participate in vulcanization reaction (different from TDAE).The results showed that LPB effectively reduced the critical strain amplitude of Payne effect (ameliorated filler dispersion) compared with TDAE plasticizing SSBR/BR. The degree of crosslinking decreased slightly, but there was no significant difference in rolling resistance and wet skid resistance at the same sulfur content. Changing the sulfur content, the wet skid resistance of tread and tensile strength of SSBR/BR vulcanizate plasticized by LPB were significantly improved, and the effect of LPB with high 1,2-vinyl content was better.
