Flowers are susceptible to many pests and diseases. Therefore, they can be sprayed several times during their growth considering that no MRL are set for flow-ers. High levels of pesticide residues potentially expose daily the florists who han-dle cut flowers and possibly could endanger their health. A study was carried out to evaluate the risk for florists exposed to fungicide residues during normal profes-sional tasks. Cotton gloves were distributed to 20 florists (two pairs to each florist) and worn during two consecutive half days during normal professional tasks (from min 2 hours to max 3 hours/day) to measure their potential dermal exposure (PDE). Samples were analyzed with a multi-residue (QuEChERS) method validated by a laboratory accredited for pesticide residues and with a combination of gas and liquid chromatography tandem mass spectrometry. It appears from the results that a total of 54 fungicides with different toxicity classes were detected on cotton gloves. An average of 15.53 mg/kg fungicide residues per glove sample was meas-ured. Six of 54 are suspected of causing cancer after prolonged or repeated expo-sure. Boscalid was both the active substance for which the highest maximum and average concentrations (26.21 and 3.47 mg/kg, respectively). Famoxadone had the most critical PDE (156% AOEL for the maximum concentration). As a consequence, this study leads to conclude that Belgian florists, who worked for several years and handled a large number of flowers contaminated by high concentrations of pesti-cide residues, are exposed daily with a potential effect on their health. This sug-gests that safety standards should be set for residue levels on cut flowers. [less ▲]

Plant protection products play a very important role in agriculture. However, their misuse can have serious negative impacts both on human health and environment. A study was carried out to identify the plant protection products used in the Niger River valley and to observe the local pesticide management practices. Ten active substances were identified as the most used chemicals by farmers. Their toxicological properties were characterized and their respective Potential Dermal Exposures (PDE) was evaluated in order to assess the risk level for the local small growers. The UK Predictive Operator Exposure Model was used to quantify the PDE during mixing/loading and application according to the local practices. The survey shows that the most common active substances are organophosphate or pyrethroids insecticides. In addition, some other prohibited and counterfeit pesticides cocktails are also used. All active substances used in Niger River valley are highly toxic. When sprayed without personal protective equipment (PPE) they could induce significant harmful impacts on the human health after exposure. The predictive exposure levels vary from 0.0013 mg/kg bw/day to 0.4125 mg/kg bw/day, several times higher the Acceptable Operator Exposure Level (AOEL) for all actives substances. The survey also revealed that 76% of operators do not use any PPE during mixing/loading or spraying. Other bad practices observed in study area can increase the exposure of operators. Moreover, local consumers could also be exposed through intake of pesticide residues on harvested products. [less ▲]

In order to investigate the relationship between desiccation and the extent of protein oxidation in desert strains of Chroococcidiopsis a selection of 10 isolates from hot and cold deserts and the terrestrial cyanobacterium Chroococcidiopsis thermalis sp. PCC 7203, were exposed to desiccation (air-drying) and analysed for survival. Strain CCMEE 029 from the Negev desert and the aquatic cyanobacterium Synechocystis sp. PCC 6803 were further investigated for protein oxidation after desiccation (drying over silica gel), treatment with H2O2 up to 1M and exposure to γ-rays up to 25 kGy. Then a selection of desert strains of Chroococcidiopsis with different survival rates after prolonged desiccation, as well as Synechocystis sp. PCC 6803 and Chroococcidiopsis thermalis sp. PCC 7203, were analysed for protein oxidation after treatment with 10 mM and 100 mM of H2O2. Results suggest that in the investigated strains a tight correlation occurs between desiccation and radiation tolerance and avoidance of protein oxidation [less ▲]
