JOURNAL OF EXPOSURE SCIENCE & ENVIRONMENTAL EPIDEMIOLOGY 2024; 34:278-286. [PMID: 36496457 DOI: 10.1038/s41370-022-00507-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 11/24/2022] [Accepted: 11/24/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND France is one of the biggest users of pesticides in Europe and exposure to pesticides is a current concern, especially when it occurs early in life. OBJECTIVE The aim of this study was to assess the exposure of pregnant women in Brittany (western France) with high pesticide use. METHODS The pesticides were selected according to agricultural practices. Forty pesticides or metabolites were measured in urine samples collected in 2004 from 296 pregnant women in Brittany. The samples were analyzed by ultra-high performance liquid chromatography (UHPLC) coupled to high resolution mass spectrometry (HRMS) after a solid phase extraction (SPE) step. RESULTS Twenty seven pesticides were detected: the most frequently detected were the metabolites of organophosphate and pyrethroid insecticides (>89%) and several herbicides (phenoxypropionic acid derivatives and fluazifop >60%). Organophosphate and pyrethroid metabolites were also quantified in highest levels with maximum values of 590 μg/l for dimethylphosphate and 5.4 μg/l for 3- phenoxybenzoic acid. For the other parent compounds, such as prochloraz, bromoxynil and procymidone, they were also detected in 10-29% of the samples. SIGNIFICANCE Our results are consistent with pesticide use at the time of collection. The median concentrations of organophosphorus and pyrethroids were of the same order of magnitude as those reported in other countries. Herbicides and fungicides (fluazifop-p-butyl, bromoxynil, and prochloraz) were measured for the first time in this biomonitoring study, showing the usefulness of measuring widely used pesticides locally to improve knowledge of exposure. IMPACT The objective of this study is to assess the exposure of pregnant women in a region of Europe with high pesticide use.

Assessment of the impact of hydrolysis on bound sulfonamide residue determination in honey using stable isotope dilution ultrahigh performance liquid chromatography tandem mass spectrometry. Food Chem 2021; 361:130094. [PMID: 34029905 DOI: 10.1016/j.foodchem.2021.130094] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 04/09/2021] [Accepted: 05/10/2021] [Indexed: 10/21/2022]
Abstract
In this study, an analytical method based on isotope dilution-liquid chromatography tandem mass spectrometry (ID-LC-MS/MS) was developed as a candidate reference method for the determination of sulfonamides (SAs) in honey. To guarantee the accuracy and authenticity, the impact of hydrolysis on bound SA residues was first investigated by enabling (i) identification of sugar-bound SAs, (ii) clarifying the binding reaction rule between the SAs and sugar, (iii) detection of free SAs and sugar-bound SAs, and (iv) preparation of SA-contaminated honey. Thus, the efficiency of different hydrolysis conditions was assessed by comparing the bound SA content before and after hydrolysis. In addition, optimization of the sample pretreatment procedures and LC conditions to minimize matrix effects by separation from significant matrix interferences was also performed. Satisfactory results in terms of hydrolysis efficiency (approximately 88.3%-99.2%), extraction efficiency (84.2%-105.3%), recovery (95.9%-103.1%), and limit of quantification (0.6-1.5 μg·kg-1) were obtained.

Abstract
Diethylstilbestrol (DES) is used as a kind of animal feed additive and affects people's health through the food chain. The purpose of this study is to detect the residue level of DES in 576 human urine samples directly. DES-BSA was used to immunize Balb/c mice. The monoclonal antibody was produced by hybridoma that was screened through cell fusion techniques. Finally, we developed the indirect competitive ELISA method to analyze 576 human urine samples from Zhejiang Province, China. The IC50 of this method was 3.33 ng/mL. The LOD and LOQ were 0.16 and 0.54 ng/mL. Linear range of the standard curve was from LOD to 12.50 ng/mL. There was no cross-reactivity with two kinds of estrogens and two structural analogs with DES. Five hundred seventy-six urine samples were analyzed by the indirect competitive ELISA method, and the detection rate was 98.78%. The mean concentration and geometric mean were 4.70 and 3.50 ng/mL. The indirect competitive ELISA method based on monoclonal antibody was sensitive and reliable for the detection of DES in human urine samples. The results warned us to pay more attention to human health and food safety.

Abstract
A liquid chromatographic (LC)-tandem mass spectrometry (MS/MS) method was developed for simultaneous determination of stilbenes, diethylstilbestrol (DES), hexestrol (HEX), and dienoestrol (DEN) in animal tissue. Sample clean-up and analyte enrichment was performed by automated solid-phase extraction (ASPE) with a silica gel cartridge. Detection capabilities (CCbeta) related to the transition products of lowest abundance for the method were 0.04-0.45 ng g(-1) in tissue and were achieved using atmospheric pressure chemical ionization (APCI) in negative mode. The use of an internal standard in combination with the simplified sample preparation led to a sensitive and reliable analytical method. The recovery level of the method was 84-108% for DES and DEN between 0.5 and 5 ng g(-1), and 59-87% for HEX between 0.25 and 2.5 ng g(-1).

Abstract
A competitive time-resolved fluoroimmunoassay (TR-FIA) was developed for the determination of 19-nortestosterone (17beta-NT) residues in aquaculture tissues. The limit of detection (LOD) was determined to be 0.08 ng g-1 and the limit of quantification (LOQ) was less than 0.8 ng g-1. The results obtained by the TR-FIA and ELISA showed a good correlation. The established TR-FIA was validated for the determination of incurred aquaculture tissues and confirmed by liquid chromatography tandem mass spectrometry (LC/MS/MS). This proposed technique could be applied to routine residue analysis.

Abstract
The lateral flow strip test for 19-nortestosterone is one kind of immunochromatographic assay. Nitrocellulose membrane was separately immobilized with goat anti-rabbit IgG (control line) and 19-NT-OVA conjugate (test line). Anti-19-NT polyclonal antibody labeled with colloidal gold particles acted as the detector reagent. The assay is qualitatively, not quantitatively, judged with positive or negative result. We tested the sensitivity of the strip using spiked swine urine, and each specimen was independently measured by LC/MS/MS. The sensitivity, measure by eye, was determined to be 200 ng/mL. The assay time was less than 15 min, and so suitable for on-site rapid test.

Abstract
A new method is presented for the analysis of 17[small beta]-estradiol in bovine urine. After deconjugation, the sample is cleaned up using an OASIS[trade mark sign] HLB disposable cartridge and extracted into 1-chlorobutane. The hormone is derivatized using pentafluorobenzoyl chloride. The derivatized estradiol is quantitated using gas-chromatography negative-ion chemical ionization mass spectrometry. Calibrations, obtained using spiked blank urine, are linear in the range of 100-1000 pg mL(-1) with CC[small alpha] approximately 170 pg mL(-1) and CC[small beta] of 287 pg mL(-1). Recoveries are in the range of 80 to 130%. The method is rugged, rapid and sensitive when compared to other hormone methods.

Abstract
The applicability of capillary electrophoresis (CE) with UV and mass spectrometric (MS) detection for the determination of dopamine and methoxycatecholamines in urine was evaluated in comparison with the liquid chromatography-electrochemical detection (LC-EC) method widely used in catecholamine analysis. The catecholamines in urine were deconjugated with acid or enzyme hydrolysis, purified by cation exchange (CEX) or solid-phase extraction (SPE) with a copolymer of N-divinylpyrrolidone and divinylbenzene and analyzed by LC-EC, CE-UV, and CE-MS. Acid hydrolysis was more effective in the deconjugation than enzymatic hydrolysis with Helix pomatia. However, the recoveries of HMBA, DA and NMN from spiked samples were less than 30% after acid hydrolysis and SPE purification. The CEX purification was more efficient than SPE in removing matrix compounds from the urine samples. The limits of detection were lower in LC-EC analysis than in CE-UV or CE-MS. Many factors in the analytical procedure caused deviations in the concentrations measured for urinary dopamine and methoxycatecholamines. The recovery of HMBA, which was used as the internal standard, was poor after acid hydrolysis and SPE purification. The purification methods were validated in conjunction with the analytical methods and therefore cross analysis was unsuccessful. The LC-EC method was the most sensitive, but CE-UV and CE-MS were sensitive enough for the determination of dopamine and methoxycatecholamines even in healthy patient urine. The EC and MS detections were superior to the UV detection in specificity since, after acid hydrolysis, some matrix compounds were migrating close to I.S., DA and 3MT.

Abstract
We developed a competitive chemiluminescent (CL) enzyme immunoassay for rapid, sensitive analysis of 19-nortestosterone (19-NT) in bovine urine. Anti-19-NT polyclonal antibodies were raised in rabbits using a 19-NT-hemisuccinate derivative conjugated with ovalbumin; the derivative was also conjugated with horseradish peroxidase (HRP) as a label. Antibodies were immobilized on 384-well black polystyrene microtitre plates and HRP-labelled 19-NT activity was measured using an efficient chemiluminescent substrate (SuperSignal ELISA Femto) after 3 min incubation. Emitted light was recorded using a conventional, photomultiplier-tube-based microtitre plate reader or a sensitive back-illuminated, cooled CCD camera. The developed method fulfils all the requirements of precision (intra- and inter-assay CV < 10%) and accuracy (mean recovery 94-112%), with a detection limit of 0.03 ppb (1.1 x 10(-9) mol/L) in a urine matrix. Chemiluminescence enhances detectability of the HRP-labelled tracer (thus lowering the limit of detection with respect to colorimetry) and reduces analysis time. The 384-well microtitre plate cuts the sample/reagent volume (20 microL), a five-fold reduction with respect to the conventional 96-well microtitre plate. The developed method is suitable for high-throughput screening of 19-NT in urine samples, with reduced costs as compared with conventional colorimetric enzyme immunoassays.
