Download or read book EVALUATION DE LA TOXICITE DES EMBALLAGES PLASTIQUES DESTINES AU CONTACT AVEC LES ALIMENTS A L AIDE DE MIGRATS D EMBALLAGE OBTENUS A PARTIR DE LIQUIDES SIMULATEURS written by Isabelle Leguy and published by . This book was released on 1997 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: LES MATERIAUX PLASTIQUES SONT TRES UTILISES DANS L'EMBALLAGE ALIMENTAIRE. CEPENDANT, CERTAINS CONSTITUANTS DE L'EMBALLAGE PEUVENT MIGRER ET CONTAMINER LES ALIMENTS. AFIN DE CONTROLER CE PHENOMENE ET DE PROTEGER LA SANTE DES CONSOMMATEURS, DE NOMBREUX PAYS ONT ETABLI UNE REGLEMENTATION. LES CONSTITUANTS COMME LES MONOMERES ET LES ADDITIFS DOIVENT FIGURER SUR LES INVENTAIRES EUROPEENS AFIN D'ETRE AUTORISES AU CONTACT ALIMENTAIRE, ET, POUR CERTAINS D'ENTRE-EUX, DES LIMITES DE RESTRICTION, BASEES SUR LEUR TOXICITE ET LEUR INTENSITE DE MIGRATION, SONT STIPULEES (DIRECTIVES 90/128/EEC ET SES AMENDEMENTS 92/39/EEC AND 93/9/EEC). MAIS LES EFFETS SUR LA SANTE DES PRODUTIS DE REACTIONS OU DE DEGRADATIONS FORMES A PARTIR DES MONOMERES ET DES ADDITIFS AU COURS DU PROCEDE DE FABRICATION, OU, DES IMPURETES DES PRODUITS DE BASE NE SONT PAS EVALUES. AUSSI LA RECHERCHE CONCERNANT LA MIGRATION DE CES SUBSTANCES POTENTIELLEMENT GENOTOXIQUES ET/OU CANCEROGENES S'AVERE INDISPENSABLE. DE PLUS, LES INTERACTIONS (SYNERGISME, POTENTIALISATION) ENTRE TOUS LES COMPOSES CHIMIQUES CEDES PAR L'EMBALLAGE NE SONT PAS PRISES EN COMPTE. NOUS AVONS MIS AU POINT UNE STRATEGIE DE CONTROLE COMPRENANT A LA FOIS DES METHODES PHYSICO-CHIMIQUES ET BIOLOGIQUES. ELLE CONSISTE EN UNE COMBINAISON D'ETUDES DE MIGRATIONS SIMPLES ET DE CRIBLAGE TOXICOLOGIQUE RAPIDE. LES QUATRE PRINCIPAUX TYPES DE MATERIAUX D'EMBALLAGES PLASTIQUES ALIMENTAIRES - POLYPROPYLENE, POLYETHYLENE, POLYSTYRENE ET POLY(TEREPHTALATE D'ETHYLENE) - ONT ETE ETUDIES. DANS UN PREMIER TEMPS, LES TESTS DE MIGRATION DES MIGRANTS NON VOLATILS ONT ETE EFFECTUES AVEC LES LIQUIDES SIMULATEURS D'ALIMENTS GRAS - ISOOCTANE PENDANT 2 JOURS A 20C ET ETHANOL 95% PENDANT 10 JOURS A 40C - SELON LES NORMES OFFICIELLES (DIRECTIVE 93/8/EEC). LES SIMULANTS ALIMENTAIRES ONT ETE ENSUITE CONCENTRES ET ANALYSES PAR CLHP AFIN D'IDENTIFIER ET DE QUANTIFIER LES ANTIOXYDANTS (ADDITIFS). DANS UN SECOND TEMPS, LA MUTAGENICITE DES MIGRATS A ETE DETERMINEE SELON LE TEST D'AMES ; LA VIABILITE DES BACTERIES A ETE PREALABLEMENT MESUREE (LES EFFETS CYTOXIQUES D'UNE SUBSTANCE OU D'UN MELANGE POUVANT INTERFERER AVEC LEURS EFFETS GENOTOXIQUES). LES RESULTATS SONT LES SUIVANTS: POUR TOUS LES MATERIAUX D'EMBALLAGES ETUDIES, LES MIGRATIONS SPECIFIQUES DES ANTIOXYDANTS AINSI QUE LES MIGRATIONS GLOBALES SONT TOUJOURS INFERIEURES AUX LIMITES REGLEMENTAIRES. DE PLUS, POUR TOUS LES MIGRANTS NON VOLATILS, AUCUNE MUTAGENICITE N'A ETE DECELEE AVEC LES SOUCHES SALMONELLA TYPHIMURIUM TA 98 ET TA 100, AVEC ET/OU SANS ACTIVATION METABOLIQUE. AFIN DE COMPLETER CES ETUDES DE GENOTOXICITE, UN AUTRE TEST DE MUTAGENICITE UTILISANT UN BIOSYSTEME PLUS PROCHE DE L'HOMME QUE LES MICRO-ORGANISMES ET POSSEDANT UN METABOLISME SPECIFIQUE COMME LE FOIE, POURRAIT ETRE ENVISAGE. TOUTEFOIS, COMME POUR LE TEST D'AMES, LA CYTOTOXICITE DES MIGRATS DOIT TOUT D'ABORD ETRE EVALUEE. POUR CETTE RAISON, NOUS AVONS MIS AU POINT LE TEST DE CYTOTOXICITE MESURANT LA VITESSE DE SYNTHESE D'ARN SUR LA LIGNEE CELLULAIRE HUMAINE HEPATOCYTAIRE HEP G2. NOUS AVONS MIS AU POINT UNE METHODE RENTABLE ET SENSIBLE PERMETTANT DE DETECTER RAPIDEMENT LES SUBSTANCES POTENTIELLEMENT MUTAGENES RELARGUEES DANS LES ALIMENTS PAR LES EMBALLAGES PLASTIQUES. AFIN DE GARANTIR LA SECURITE DES CONSOMMATEURS, NOUS PROPOSONS QUE CETTE STRATEGIE DE CONTROLE SOIT UTILISEE PAR LES INDUSTRIES ET LES AUTORITES REGLEMENTAIRES IMPLIQUEES DANS L'EMBALLAGE PLASTIQUE ALIMENTAIRE

Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.
