Assessment of occupational exposure to pesticides in Spain through a job-exposure matrix (MatEmESp, 1996-2005)
2014
Introducción: La exposición laboral a plaguicidas ha sido asociada a numerosos problemas de salud. Sin embargo, la información sobre la exposición de los trabajadores afectados en España es escasa y dispersa. Objetivos: El objetivo de este trabajo fue estimar el nivel y la prevalencia de la exposición laboral a plaguicidas en España para el periodo 1996-2005, como parte del proyecto de construcción de la matriz empleo-exposición española, MatEmESp. Métodos: El establecimiento de las ocupaciones expuestas, los agentes de referencia y las estimaciones de exposición se basó en información de otras matrices, datos de evaluaciones de riesgos en empresas españolas y revisión de la bibliografía.

Peut-on concilier un faible usage de pesticides, une bonne performance économique et environnementale ? Analyse d’un réseau national de fermes de dém…
2017
Feeding an increasing world population with a sustainable agriculture is one of the greatest challenges of this century. The reduction of the reliance on pesticides is a critical aspect in this quest for sustainability. Whether cropping systems with reduced reliance on pesticides would be able to reconcile the various components of sustainability remains however a matter of debate. Are they as productive and profitable than current mainstream cropping systems? Here the objective is to study the feasibility of a reduced reliance on pesticides in France. We used a unique dataset from a national network of more than thousand arable commercial farms between 2009 and 2011. Launched in the framew…
Assessment of pahs and selected pesticides in shallow groundwater in the highest protected areas in the Opole region, Poland
2014
The ground water quality was determined after the analyses of water samples from 18 wells. The wells were in the Groundwater Area with the Highest Protection (Triassic water, Opole region, Poland), rural build up. The water table level was low: 0.5 – 18.0 m below the ground surface level (except for one artesian well). The following parameters were determined: pH, EC, colour, ammonium, nitrite, nitrate, dissolved orthophosphate, total phosphorus, dissolved oxygen, BOD, COD-Mn, COD-Cr, humic substances, chloride, sulphate, total hardness, alkalinity, dry residue PAHs (16 compounds), pesticides (6 compounds), however, only selected data were presented in this paper. In all the analysed water …

Determination of glyphosate and its metabolite aminomethylphosphonic acid in fruit juices using supported-liquid membrane preconcentration method wit…
2005
Abstract The application of supported-liquid membrane (SLM) technique for effective extraction of N -(phosphonomethyl)glycine (glyphosate) and its primary metabolite aminomethylphosphonic acid (AMPA) from juices (orange, grapefruit, apple and blackcurrant) in combination with HPLC-UV detection after derivatization with p -toluenesulphonyl chloride (TsCl) is presented. The influence of various parameters such as the composition of acceptor phase, flow-rate, concentration of analytes, on the performance of extraction procedure, was studied. It was shown that by appropriate manipulation of SLM parameters the level of detection could be significantly improved. The influence of SLM conditions on…
Environmental remediation using nanomaterial as adsorbents for emerging micropollutants
2023
Water shortage and scarcity are issues of global concern. Water pollution caused by organic micropollutants further aggravates the problem, by rendering an already scarce resource unfit for human consumption. The existing conventional wastewater treatment methods and infrastructure were not designed to eliminate micropollutants. Therefore, their inefficiencies call for modern methods for removing emerging micropollutant residues such as Active Pharmaceutical Ingredients (APIs), Endocrine Disrupting Compounds (EDCs), personal care products and pesticides. The use of nanomaterials, for the abatement of micropollutants in water is gaining traction in recent years, due to the abundance of susta…
Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique
2021
In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …
