“…The extraction solvent is an important parameter in order to achieve an efficient extraction of Fnx. In this work, a solution of n ‐exane/dichloromethane (1:1, v/v) was used for its ability to extract pesticides from mussel samples . Using two extraction cycles at 100 bar and 100°C, a good extraction efficiency was obtained.…”

The aim of this work was to develop an efficient method for the selective extraction and analysis of fenoxycarb, a carbamate pesticide, in mussel samples using a molecularly imprinted solid‐phase extraction device. The optimization of molecularly imprinted polymer synthesis was performed using the experimental design under the response surface methodology approach. A fast rebinding study and Freundlich isotherm adsorption were carried out to calculate binding capacity B, site number n, and affinity constant Kf. The optimum molecularly imprinted polymer was successfully used as sorbent of a solid‐phase extraction cartridge for the determination of fenoxycarb in real mussel samples. The range of linearity was 0.3–30 mg/L with a correlation coefficient of 0.991. The limit of detection was 0.247 mg/kg. The recovery of fenoxycarb extracted from mussel samples of Mediterranean sea was 97% (n = 3) with relative standard deviation between 6 and 7% proving the reliability of the developed method.

“…285-288 When considering similar congener compositions measured worldwide, the range of total PBDEs in soils and sediments of the Bắc Giang Province is comparable to those detected in impacted Turkish soils or Chinese sediments 35 The reviewer is right, the comparison with standards and international guidelines would be much more significant. Unfortunately, no such comparison is possible for PBDE at present because only the US-EPA has defined screening levels in residential and industrial soils.…”

“…The eluates were collected as one single fraction. Purified samples were reduced to 100 μL under a gentle nitrogen flow at 23°C and spiked with a known amount of the recovery standard solution (1 13 C-labelled PAHs at ng μL −1 , 2 13 Clabelled PCBs at pg μL −1 and 2 13 C-labelled PCDD/Fs at 20 pg μL −1 ; CIL Inc.) according to the method fully described in Pizzini et al [41,47].…”

Open burning of agricultural waste is still a common practice as it is a rapid method for waste disposal, although natural biomass, including agriculture residues, can be exploited as a renewable energy source. We assessed the viability and sustainability of using vineyard pruning residues, as wood chips, for energy conversion. Wood chips, obtained from vineyards in the Prosecco DOCG region (Italy), were characterized in terms of chemical composition, calorific value, ash content and humidity. Combustion tests were performed in a medium-size biomass boiler (maximum power 500 kW) to assess the viability of the approach in terms of sustainable steady-state combustion. Primary emissions of both macro-and micro-pollutants were measured to assess the environmental impact.An analytical method was purposely developed for the determination of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in three matrices: fly ashes, condensate and gas. The results showed that vineyard pruning residues can be used for energy conversion in medium-and large-scale biomass boilers. Primary emissions of measured pollutants were all below limit values set by current European legislation except for particulate matter, for which current available abatement technologies are required to contain emissions, thus making the use of vineyard pruning residues unsuitable for combustion in domestic appliances where such technologies are not installed. Bottom ashes produced during combustion were also characterized to assess whether they can be recycled in the vineyard as soil amendments/fertilizers. Copper content in combustion ashes exceeded limit values for ashes to be used as fertilizers in agricultural fields for some European countries but not for others, indicating that ashes may need to be disposed as waste.
