“…EDCs are ubiquitous because of their abundant use in many industrial and agricultural applications [360]. Most EDCs are synthetic organic chemicals introduced into the environment by anthropogenic sources, but they can also be naturally generated by the estrogenic hormones 17β-estradiol and estrone in humans exposured to EDCs especially via drinking water.…”

Electronic-nose (e-nose) instruments, derived from numerous types of aroma-sensor technologies, have been developed for a diversity of applications in the broad fields of agriculture and forestry. Recent advances in e-nose technologies within the plant sciences, including improvements in gas-sensor designs, innovations in data analysis and pattern-recognition algorithms, and progress in material science and systems integration methods, have led to significant benefits to both industries. Electronic noses have been used in a variety of commercial agricultural-related industries, including the agricultural sectors of agronomy, biochemical processing, botany, cell culture, plant cultivar selections, environmental monitoring, horticulture, pesticide detection, plant physiology and pathology. Applications in forestry include uses in chemotaxonomy, log tracking, wood and paper processing, forest management, forest health protection, and waste management. These aroma-detection applications have improved plant-based product attributes, quality, uniformity, and consistency in ways that have increased the efficiency and effectiveness of production and manufacturing processes. This paper provides a comprehensive review and summary of a broad range of electronic-nose technologies and applications, developed specifically for the agriculture and forestry industries over the past thirty years, which have offered solutions that have greatly improved worldwide agricultural and agroforestry production systems.

“…), crustacea (Daphnia magna, Artemia franciscana) and bacteria (Vibrio fischeri) (Lundstrom et al, 2010;Tigini et al, 2011) whereas the endocrine interference is generally evaluated by means of human cell lines or yeasts (Jobling, 1998). Assays include estrogen receptor (ER) binding, ER-dependent transcription system, and proliferation of estrogen dependent cell lines such as MCF-7 cells; they can determine the total estrogenic EDCs activity of environmental samples (Berckmans et al, 2007;Nelson et al, 2007;Schilir o et al, 2009).…”

a b s t r a c tThis study describes a multidisciplinary approach that investigates the breakdown potential of a laccase mediated system from Trametes pubescens MUT 2400 against several micropollutants including already recognized endocrine disrupting chemicals at their natural residual concentrations (from mg/L up to ng/ L).In model solution, the chemical speciation focused on a mixture of 18 analytes and adopted stir bar sorptive extraction with directed in-situ derivatization followed by gas chromatography and mass spectroscopy analysis. The method's key performance parameters were evaluated in consideration of the chemical peculiarities and complexity of real wastewaters: precision, accuracy, estimated working range extended to a wide residual concentration interval (10 ng/L to100 mg/L) indicated its fitness for purpose. Laccases were extremely active towards all the target compounds, both in term of removal yields and rate. The maximal percentage of removal was obtained for 4-t-butylphenol, 2-hydroxybiphenyl, 4-noctylphenol, salicylic acid and estrone (percentage of removal above 90%). Enzymes concentration played a central role and in most of the cases, the catalyzed reactions were very fast: the initial concentration of 9 compounds was halved within the first 3 h.The laccase-mediated treatment was then applied to a municipal wastewater collected in a real wastewater treatment plant, containing at least 9 xenobiotics as drugs, pesticides, plasticizers and personal care products. Although the harsh chemical and biological conditions of the effluent influenced enzyme stability, the reaction took place, and above 70% transformation was obtained for most analytes during the 24 h experiment. Bioassays were carried out to estimate the estrogenic activity (the E-screen test and the MELN gene-reporter luciferase assay) and the ecotoxicity (Lepidium sativum, Pseudokirchneriella subcapitata and Vibrio fischeri), demonstrating the capability of laccases to mediate an effective detoxification of the wastewater and a decrease of the estrogenic activity. treatment plant; U/L, enzymatic activity expressed as International Unit per liter; PR, percentage of removal; MEC, minimal effective concentration; t 1/2 , analyte half-life; Ti, Target Ions; RSD%, relative standard deviation percentage; LOQ, limit of quantification; QCx, quality control samples; Rel.Err %, relative error percentage; COD, chemical oxygen demand; GI%, germination index; I%, inhibition percentage of the algal growth or of the bacterial bioluminescence; EEQ, 17-b-estradiol equivalent quantity; RPE %, relative proliferative effect; TRANS%, rate of luciferase gene expression.

“…The E-screen assay was carried out according to the method of Korner et al [42], modified by Schilirò et al [43] and adapted to food samples. Briefly, subconfluent MCF-7 BUS cells were trypsinised and resuspended in steroid-free experimental medium.…”
