Incidence of dairy wastewater on morphological and physiological comportment of Chemlali and Chetoui olive

In the present study the analysis of the physico-chemical parameters of the collected TWW shows the BOD, COD, COT, Cl-, NO3, NO2, suspended matter, organic matter, turbidity and conductivity were in accordance with the required Tunisian legislations. In the same occurrence, the ICP-MS and the UPLC-MS/MS analysis show that TWW were devoid of different toxic metals and antibiotics, respectively. We opted to reuse of the TWW in the irrigation of young olive trees of two varieties: Olea europaea L. cv. Chetoui and Olea europaea L. cv. Chemlali which receiving 1 L/week of TWW during five months. Results show that dry roots weight and the content of chlorophyll a in 'Chetoui' variety increased significantly (p < 0.05) when compared to the control group. On the same way, significantly increase of leaf area, dry roots and leaves weights was observed in 'Chemlali' variety treated with TWW.

When Did We Begin to Spell 'Heteros*Edasticity' Correctly?

Using digitized texts scanned by Google and subjected to optical character recognition, I show that heteroskedasticity overtook heteroscedasticity as the preferred spelling in 2001 and has continued to dominate, except for 2005, up to 2008. The latest trends indicate that writers are moving toward the k variant. However, for words such as homoskedasticity, heteroskedastic, and homoskedastic, the corresponding spellings using c are still overwhelmingly dominant, albeit slowly shifting.Unter Verwendung von Texten, die durch Google digitalisiert und einem Texterkennungsprogramm unterzogen wurden, zeige ich, dass sich heteroskedasticity gegenüber heteroscedasticity 2001 als bevorzugte Schreibweise durchsetzte und, mit Ausnahme von 2005, bis 2008 weiterhin vorgeherrscht hat. Die aktuellen Entwicklungen deuten darauf hin, dass Verfasser vermehrt die k-Schreibweise verwenden. Allerdings ist für Wörter wie homoskedasticity, heteroskedastic und homoskedastic die Schreibweise mit c immer noch deutlich stärker verbreitet, wenngleich auch hier ein langsamer Wandel stattfindet

Pesticide Residues on Three Cut Flower Species and Potential Exposure of Florists in Belgium

In order to assess the prevalence of pesticide contamination and the risk of florists’ exposure when handling cut flowers, sampling and analysis of 90 bouquets of the most commonly sold cut flowers in Belgium (50 bouquets of roses; 20 of gerberas, and 20 of chrysanthemums) were carried out. The bouquets were collected from 50 florists located in the seven largest cities of Belgium (Antwerp, Brussels, Charleroi, Ghent, Leuven, Liege, and Namur) and from five supermarkets located in the different regions. To have a better understanding of the route of exposure and professional practices a questionnaire was also addressed to a group of 25 florists who volunteered to take part in the survey. All florists were interviewed individually when collecting the questionnaire. The residual pesticide deposit values on cut flowers were determined in an accredited laboratory using a multi-residue (QuEChERS Quick Easy Cheap Effective Rugged Safe) method and a combination of gas chromatography (GC) and liquid chormatograhphy (LC) analysis. A total of 107 active substances were detected from all samples; i.e., an average of about 10 active substances per bouquet. The most severely contaminated bouquet accumulated a total concentration of residues up to 97 mg/kg. Results show that roses are the most contaminated cut flowers; with an average of 14 substances detected per sample and a total concentration per rose sample of 26 mg/kg. Some active substances present an acute toxicity (acephate, methiocarb, monocrotophos, methomyl, deltamethrin, etc.) and exposure can generate a direct effect on the nervous system of florists. Nevertheless, fungicides (dodemorph, propamocarb, and procymidone) were the most frequently detected in samples and had the highest maximum concentrations out of all the active substances analysed. Dodemorph was the most frequently detected substance with the highest maximum concentration (41.9 mg/kg) measured in the rose samples. It appears from the survey that, despite being exposed to high deposits of residues, florists usually do not protect themselves from contact with residues even if they spend several hours handling cut flowers and preparing bouquets (from 2 to 6 h/day, depending on the time of year and/or selling periods) daily. Bad habits (eating, drinking, or smoking at work) and absence of personal protective equipment of most florists also increase the risk of contact with pesticide residues

A survey of pesticide residues in cut flowers from various countries

As in any intensive culture, flowers require the use of a wide range of pesticides to control diseases and pests which can damage production and marketability. In order to evaluate the average levels of contamination of the cut flowers and to assess the risk for professionals exposed to pesticide residues when handling cut flowers, a survey was carried out with a group of florists from the Belgian largest cities. Fifty samples of roses (5 stems per bouquet) were collected: 45 bouquets were sampled in the 7 largest cities of Belgium (Antwerp, Brussels, Charleroi, Ghent, Leuven, Liege and Namur) and 5 were sampled from 5 supermarkets. Analysis of residual pesticide deposit is made by combining two multi-residue methods (GC-MS-MS and LC-MS-MS) in a laboratory accredited for pesticide residues. For all the samples analysed, a total of 97 active substances were detected, i.e. an average of 14 active substances per bouquet and a total average pesticide load of 26,03 mg/kg per flower sample. Most active substances (a.s.) reached high levels of residues, with concentrations between 10 and 50 mg/kg. Samples from Belgium and The Netherlands have a lower average number of a.s./sample, but the amount of residues is about the same in all samples (20-30 mg/kg) whatever the country of origin , except for the sample from Germany who is the worst case (22 a.s. with a total amount of 92 mg/kg). Most of the detected active substances are fungicides (dodemorph, spiroxamine, cyprodinil, fluopyram, pyrimethanil, benomyl (carbendazim), propamocarb, boscalid and iprodione) which are present on more than 20 of the 50 samples. All of them have a dermal acute toxicity. Consequently, florists who handle a large number of flowers are exposed daily with a potential effect on their health
