  First report on the presence of Alloxan in Bleached Flour by LC-MS/MS Method
  https://doi.org/10.31396/Biodiv.Jour.2019.10.4.493.494

  ABSTRACT
  Alloxan is a ketone with a low molecular weight and neutral functional groups. In this work the presence of Alloxan in bread, pastry and cake bleached flour was investigate in order to verify possible risk for consumers related to the use of chemicals for flour bleaching.

  Determination of Chlorpyriphos in Sicilian peaches by Gascromatography-MSMS method coupled with quechers sample preparation procedure preparation

  ABSTRACT
  Chlorpyrifos is an organophosphate pesticide used to kill a number of pests including insects and worms. It is considered moderately hazardous to humans by the World Health Organization and is harmful for these classes of animals. Gas chromatography tandem mass mass spectrometry (GC-MS) was used for the quantification and confirmation of Chlorpyrifos pesticide residues in peaches. The analysis carried out on peach samples confirmed that chlorpyrifos are widely used in Sicilian territory so that 34 percent of the samples were contaminated by the pesticide.

  Use of terrestrial gastropods (Cornu aspersum) as bioindicators of the environmental contamination status of the Sicilian Natural Parks to assess the contamination status of the pastures
  https://doi.org/10.31396/Biodiv.Jour.2019.10.4.471.473

  ABSTRACT
  The use of land molluscs in biomonitoring can evidence interactions between the contaminant and the biotic sphere. The concentration of heavy metals were determined by ICP-MS. In areas where anthropic and industrial contamination persist, heavy metal levels were above the quantification limit; sampling in agricultural areas shows lower levels of heavy metals. The same trend of results can be found for the analysis of IPAs. Snails can be considered as bioindicators of pollutants living in close contact with the soil and ingesting plants with a high concentration of contaminants.

  Investigation on the presence of Dioxins in the Sicilian Sheep’s milk
  https://doi.org/10.31396/Biodiv.Jour.2019.10.4.463.464

  ABSTRACT
  Our studies were conducted in 2016 and several sicilian sheep farms were involved. The goal of this research was to evaluate the possible use of sheep as a “sentinel” body to be used as a biological indicator for environmental biomonitoring of dioxins. For the determination of dioxins in sheep’s milk was used a method on high-resolution gas chromatography along with a high resolution mass spectrometry (HRGC/HRMS) in order to evaluate the existence of dioxins with concentrations exceeding the limits imposed by the EC Regulation 1881/2006. A total of 200 samples were analyzed, of which 14 samples exceeded the limits imposed by the EC Regulation 1881/2006: 3.0 pg/g fat sum of dioxins (WHO.PCDD/F-TEQ). It is conceivable that the proximity to high anthropization areas and industrialization, may have a positive influence on the propagation of dioxins in the environment having been detected values exceeding the allowed limit. The samples with low dioxin concentrations were analyzed, with values not exceeding the prescribed limit.
