Abstract
Endocrine-disrupting compounds as pesticides affect the hormonal balance, and this can result in several diseases. Therefore, the analysis of representative hormones with acetamiprid (AC) and azoxystrobin (AZ) was a good strategy for the investigation of the endocrine-disrupting activity of pesticides. Hence, a sensitive and rapid analytical method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed. The method was validated for the analysis of AC, AZ, estriol, estrone, progesterone, and testosterone in the serum, testis, and liver of rats. The correlation between the residues of pesticides and the disturbance of the endocrine system was evaluated. The different mass parameters, mobile phase types, analytical columns, injection volumes, and extraction solvents were compared to get the lowest limit of detection of the studied compounds. The detection limits of AC, AZ, estriol, estrone, progesterone, and testosterone were 0.05, 0.05, 1.0, 10, and 1.0 ng/ml, respectively. The method developed was applied to evaluate the changes in these hormones induced by the duration of exposure to AC and AZ in rat testis and serum. The hormones level in rat serum and testis had a significant decrease as they were oral gavage treated with different high concentrations of studied pesticides. Both pesticides were distributed in the body of rats by the multi-compartment model (liver, testis, and serum).

Abstract
Long-term use of a single fungicide increases the resistance risk and causes adverse effects on natural ecosystems. Controlled release formulations of dual fungicides with different modes of action can afford a new dimension for addressing the current issues. Based on adjustable aperture and superhigh surface area, metal-organic frameworks (MOFs) are ideal candidates as pesticide release carriers. This study used Al3+ as the metal node and 2-aminoterephthalic acid as the organic chain to prepare aluminum-based metal-organic framework material (NH2-Al-MIL-101) with "cauliflower-like" structure and high surface area of 2359.0 m2/g. Fungicides of azoxystrobin (AZOX) and diniconazole (Dini) were simultaneously encapsulated into NH2-Al-MIL-101 with the loading content of 6.71% and 29.72%, respectively. Dual fungicide delivery system of AZOX@Dini@NH2-Al-MIL-101 demonstrated sustained and pH responsive release profiles. When the maximum cumulative release rate of AZOX and Dini both reached about 90%, the release time was 46 and 136 h, respectively. Furthermore, EC50 values as well as the percentage of inhibition revealed that AZOX@Dini@NH2-Al-MIL-101 had enhanced germicidal efficacy against rice sheath blight (Rhizoctonia solani), evidenced by the synergistic ratio of 1.83. The present study demonstrates a potential application prospect in sustainable plant protection through co-delivery fungicides with MOFs as a platform.

Abstract
As a lipophilic fungicide, pyraclostrobin is highly toxic to aquatic organisms, especially to fish. In recent years, research has mainly focused on the pyraclostrobin residue in fish tissues under chronic toxicity, but less is known about its distribution in fish tissues under acute toxicity conditions. In this study, the distribution of pyraclostrobin in fish tissues (blood, liver, muscle and gill) was determined by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The purification effects of different purification materials [1) mixtures of PSA, C18 and MgSO4; 2) QuEChERS-PC; and 3) Oasis HLB SPE] were compared for the detection of pyraclostrobin in fish tissues. Finally, the quick and easy clean-up tool of the Oasis HLB SPE procedure was selected. Under optimum conditions, the linearities had a good relationship (determination coefficient R2 > 0.999). The mean recoveries of the analyte for all tested concentrations ranged from 86.94% to 108.81% with RSDs of 0.7%-4.9%. The pyraclostrobin residue amount was much different in fish tissues. Furthermore, the pyraclostrobin residue in different fish tissues increased initially and then decreased gradually. The concentrations in each tissue were initially ranked before 120 min in the following order: gill > liver > blood > muscle. These phenomena may be attributed to the stress response of fish under acute poisoning. This is the first study to document the distribution of pyraclostrobin in fish tissues under acute toxicity conditions, and it provides reference for the management of agrochemicals in terms of aquatic ecological risks.
