Intended Use
The Fenpropathrin ELISA is an immunoassay for the detection of fenpropathrin in contaminated samples.
Storage
The Fenpropathrin ELISA Kit should to be stored in the refrigerator (4-8°C). The solutions must be allowed to reach room temperature (20-25°C) before use. Reagents may be used until the expiration date on the box.
General Description
Fenpropathrin is a synthetic pyrethroid and possess high insecticidal activity. It is used to control many species of mites and insects like whiteflies, cotton field crops, glass house crops, vegetables. Appreciable levels of pyrethroid residues can occur in food commodities from crops, food of animal origin (eg. milk, eggs and meat), soils, sediments, and surface, ground and drinking water.

Evaluation of Quechers Sample Preparation and GC Mass Spectrometry Method for the Determination of 15 Pesticide Residues in Tomatoes Used in Salad Production Plants

IRANIAN JOURNAL OF PUBLIC HEALTH

Authors: Jahanmard, Elham; Ansari, Fatemeh; Feizi, Mansour

Background: The present study was the first attempt for determination and measurement of pesticide residues in tomatoes used in salad production plants in Isfahan, central Iran. Methods: A multiresidue method based on modified QuEChERS (quick, easy, cheap, effective, rugged and safe) sample preparation, followed by Gas Chromatography Mass Spectrometry (GC-MS) was developed and validated for the determination of 15 pesticides (permethrin, primicarb, dichlorvos, diazinone, fenpropathrin, carbaryl, chlorpyrifos, malathion, chlortalonil, brompropilate, propargit, tetradifone, phosalone, iprodion and endosulfane) from different classes. The recovery yields ranged from 83.84 to 119.73% and the relative standard deviation (RSD) was below 20.54%. The limits of detection (LODs) were between 1.63 to 10.5 mg/kg and the limits of quantifications (LOQs) were between 5.43 to 35 mg/kg. The method has been successfully applied to the analysis of 22 tomato samples obtained from salad production plants in Isfahan in Sep to Dec 2014. Results: An amount of 31.81% of samples showed contamination above maximum residue levels (MRLs) with pesticides. In addition, 13.6% of samples had contamination with diazinone and 18.18% of samples with chlorpyrifos. Conclusion: A full consideration is essential for tomatoes used in salad and food productions. It suggests a need for revision of the current trend of supervision for tomatoes and other vegetables presented in wholesale markets. In all, the study confirms that pesticide residue determination in food products, especially in raw fruits and vegetables, is a very demanding task in public health safety and trade.

Pesticide residues in nut-planted soils of China and their relationship between nut/soil

CHEMOSPHERE

Authors: Han, Yongxiang; Mo, Runhong; Yuan, Xinyue; Zhong, Donglian; Tang, Fubin; Ye, Caifen; Liu, Yihua

Twenty-nine pesticide residues in nut-planted soils from China were investigated. One organophosphate (chlorpyrifos) was detected in 53% soils, and the residue levels of 7.2 mu g/kg to 77.2 mu g/kg. The concentrations of six organochlorines (DDT, HCH, endosulfan, quintozene, aldrin and dieldrin) detected in 78.9% soils were 0.6 mu g/kg to 90.1 mu g/kg. The residue levels of six pyrethroids (bifenthrin, fenpropathrin, cyhalothrin, cypermethrin, fenvalerate and deltamethrin) detected in 65.8% soils were 1.5 mu g/kg to 884.3 mu g/kg. Triadimefon and buprofezin were found in 71.1% and 52.6% samples, respectively, with the corresponding concentrations of 9.8 mu g/kg to 193.7 mu g/kg and 87.9 mu g/kg to 807.4 mu g/kg. The multiple residues were found in 76.3% soils. A significant correlation between pesticide residues in nuts and soils was observed, with the correlation coefficient (r) 0.83 (P < 0.001). In addition, the bioconcentration factor (BCF) values for the explanation of pesticides from soils into nuts were ranged from 0.8 to 16.5. The results showed that some pesticides could accumulate in nut by the uptake effect from soil. (C) 2017 Elsevier Ltd. All rights reserved.
