Dislodgeable Foliar Residue Measurements and Assessment of Dermal Exposure to Captan for Workers in Apple Orchards.

Captan dislodgeable foliar residues (DFRs) were determined by following the applications of this fungicide in an apple orchard. The study comprised an investigation of the variability of captan DFR values and 14 days of DFR monitoring to assess kinetic modeling. A method combining solid-phase microextraction (SPME) gas chromatography and high-resolution mass spectrometry (GC-QTOF-MS) was developed for the quantification of captan residues from DFR aqueous extracts.

Pesticide Exposure of Residents Living in Wine Regions: Protocol and First Results of the Pestiprev Study.

The PESTIPREV study has been designed to investigate residential exposure to pesticides applied to vines and ultimately propose mitigation measures. A feasibility study was carried out to validate a protocol for measuring six pesticides in three houses located near vineyards in July 2020. Samples included indoor and outdoor surfaces sampled with wipes ( = 214), patches on the resident's skin ( = 7), hand or foot washing ( = 5), and pets sampled using wipes ( = 2).

Pesticide exposure of workers in apple growing in France.

Objective: Although apple trees are heavily sprayed, few studies have assessed the pesticide exposure of operators and workers in apple orchards. However, these data are crucial for assessing the health impact of such exposures. The aim of this study was to measure pesticide exposure in apple growing according to tasks and body parts.

Basis of a FTIR spectroscopy methodology for automated evaluation of Akt kinase inhibitor on leukemic cell lines used as model.

The PI3K/Akt-signaling pathway, associated with cancer development and disease progression, is recognized to be an anti-tumor drug target that could present important therapeutic benefit. However, no targeted Akt medicines have been commercialized yet, reflecting that drug selection procedures requires significant improvement from early research to clinical trials. Thus, new methods permitting both the evaluation of cytotoxic and proliferation inhibition effect on cancer cells but also to provide a global fingerprint of the drug action mechanism of new Akt inhibitor candidates are of major interest.

Selenium exposure in subjects living in areas with high selenium concentrated drinking water: results of a French integrated exposure assessment survey.

Background: Selenium is an essential element which can be toxic if ingested in excessive quantities. The main human exposure is food. In addition, intake may be boosted by consumption drinking water containing unusual high selenium concentration.

Kinetic and mechanistic investigations of progesterone reaction with ozone.

The removal of progesterone by ozone in aqueous solution was studied in this work. The absolute rate constant was evaluated and first by-products were identified. The reaction was studied in the 2.
