Iaciofano, E. Schimmenti, S. Lo Brutto*Department STeBiCeF, University of Palermo, Palermo, Italy*E-mail: sabrina.lobrutto@unipa.itInvasive alien species (IAS) can influence whole ecosys-tems altering habitats and local biodiversity, modifying themarine activities (including fishing and tourism) and introduc-ing diseases that threaten human health. However, they mayhave positive impacts on the composition of local fauna andbiotic interactions. The record and the spread monitoring inthe Mediterranean Sea of the invasive aorid amphipod crus-tacean Grandidierella bonnieroides is an example of positiveeffect on local biodiversity. In 2014, the species was record-ed with explosive abundance along Haifa Bay, in the north ofIsraeli coast, on soft bottom. Over the last two years, thisspecies has spread throughout the Israeli coast, probably byship fouling or ballast sediments, showing constant abun-dance so that it is possible considered established along theIsraeli coast and part of the local fauna. The presence of G.bonnieroides did not induce a change on assessment ofautochthonous species but only an increasing of local biodi-versity. Soft bottom biodiversity is commonly lower than hardbottom; so, the new colonization of G. bonnieroides as pos-sible read as an increasing of food available for the localfauna that feeding on macrozoobenthos. Finally, consideringthat this species has a short turn over and large range of tol-erance (salinity, temperature and substrate) is a good candi-date for food in aquaculture. This study showed that knowl-edge of invasive species is still underestimated and that, con-sequently, the direct or indirect introduction of alien speciesby human activities can bring benefits to local scale and beused as new resource for marine culture.ASSESSMENT OF HEAVY METAL CONTAMINATION INTERRACES FOR PUBLIC USE RECOVERED IN THE CITYOF PALERMO AND IN AGRICULTURAL TERRACESF. Venturella1, A. Sciara2, C. Giambelluca3, A. Ciani2*1Department of Biological, Chemical and PharmaceuticalSciences and Technologies, University of Palermo, Palermo,Italy; 2Graduated in Pharmacy, University of Palermo, Palermo,Italy; 3Laboratory Manager SOGEST, Palermo, Italy*E-mail: a91.ciani@gmail.comThe contamination by heavy metals in the soil is nowadaysconsidered an indicator of environmental pollution caused byto several factors, such as waste disposal, industrial dis-charges and the use of irrigation water. Developed in collab-oration with SO.GEST Ambiente Laboratory, in Palermo, thisstudy had as a purpose to monitor the levels of heavy metals- Cd, Cr, Fe, Mn, Pb, Zn -both in public lands and in agricul-tural terrains. All the soil samples collected have been subject-ed to an acid extraction process by using HCL and eventuallyto a mass spectrometer-based analysis for the quantitative/qualitative determination, specifically by the technique offlame atomic absorption spectrophotometer (FAAS) andgraphite furnace (GFAAS). From the elaboration of the results,it emerged that all the soils in the city of Palermo featureheavy metals, with the predominance of Cd, Cr and Zn,respectively in the percentages of 5.69%, 64.06%, 1.40% on60 soil samples analyzed, what is surely due to vehicular traf-fic, the use of irrigation water and also the use of fertilizers.Lead (Pb), instead, has not been detected in all publicgrounds, probably due to the switch-over to the lead-freegasoline, which has reduced the inflow of this metal. Lastly,the confrontation between the two types of soil showed ahigher rate of contamination by heavy metals in the agricultur-al grounds, thus demonstrating how today the use of plantprotection products has gained the upper hand, in order toincrease agricultural production. In particular, the percent-ages found are the following: Cd 6. 37% Cr 210.06%, Fe20.42, Mn 9.35%, Pb 125.1%, Zn 2.04 on 60 samples ofsoil. Although all metal concentrations have fallen within thelimit values  of the law, this will not exclude the fact that theyare present into the soil and that even though in minimal con-centration they are toxic to the man by contact, by ingestionor by respiratory action.CONTAMINATION CONTROL OF AFLATOXINS INMILK INTENDED FOR HUMAN CONSUMPTION:COMPARISON OF DATA OBTAINED BETWEEN 2014AND 2017F. Venturella1, A. Ciani2*, C. Giambelluca3, A. Sciara21Department of Biological, Chemical and PharmaceuticalSciences and Technologies, University of Palermo, Palermo,Italy; 2Graduated in Pharmacy, University of Palermo, Palermo,Italy; 3Laboratory Manager SOGEST, Palermo, Italy*E-mail: a91.ciani@gmail.comAflatoxin M1 (AFM1) is the hydroxylated metabolite on thehepatic level of aflatoxin B1 (AFB1), found in milk when theanimal is lactating after ingestion of zootechnical feeds con-taminated with aflatoxin B1. Exposed with the present work isa study conducted at the laboratory So.gest s.r.l of Palermo,which lasted more than three years, on the presence ofMycotoxins in bovine milk which provenance is from farms inthe Sicilian area of Catania, Enna and Caltanissetta in orderto determine whether during this period some changes in con-centration of aflatoxin M1 (AFM) have occurred and access ifthe presence of the toxin is always within the legal limits. Theanalyzes were conducted with ELISA method on samples ofmilk just milked, and stored in the refrigerator of the laborato-ry some samples at 3°C±1°C. The study was carried out onthe product to quantify Mycotoxins and ensure compliancewith the limit imposed by EC Regulation 1881/2006, pub-lished in the EU Official Journal on 20.12.2006. The ECRegulation 1881/2006 establishes for aflatoxin M1 (AFM1) amaximum limit tolerated (LM) of 0.050 µg/kg (50 ppt) for milkand 0.025 µg/kg (25 ppt) for the milk intended for the firstchildhood. The analyses carried out in these four years haverevealed that in all the samples the presence of AFM1 hasbeen found. In this last period, only one sample was found tohave a mycotoxin concentration above the limit required bycurrent regulations.AQUACULTURE, IS EVERYTHING ALL RIGHT?E.
