LA FINE... DELLA FINE DEL MONDO. Plastica Super tossica. Mamme, non usiamola più ! Migliaia di veleni sconosciuti nella plastica di tutti i giorni: TREMENDO. Veleni per imballare anche prodotti BIO. Ricercatori norvegesi hanno identificato solo 260 della 1.400 SOSTANZE TROVATE NELLA PLASTICA. Molte sono sconosciute (scarti industriali smaltiti illegalmente, o residui di pesticidi revocati perchè tossici? meglio indagare a fondo). link: https://pubs.acs.org/doi/10.1021/acs.est.9b02293# Oltre 4.000 prodotti chimici trovati in imballaggi di plastica, ma ve ne possono essere molti di più, soprattutto in quella riciclata. “La plastica contiene sostanze chimiche che innescano effetti negativi”, ha detto Wagner. Tali sostanze chimiche non dovrebbero essere nella plastica.” Salviamo i nostri figli dalla plastica e dai pesticidi ...ora omai più, è troppo tardi per non fare nulla,
We hypothesized that the toxicity present in plastics can be benchmarked based on the polymer type. Further, we tested the hypothesis that their chemical signature predicts the toxicity. Finally, we aimed at identifying and prioritizing the chemicals leaching from plastics.

Most (74%) of the 34 plastic extracts contained chemicals triggering at least one end point, including baseline toxicity (62%), oxidative stress (41%), cytotoxicity (32%), estrogenicity (12%), and antiandrogenicity (27%). In total, we detected 1411 features, tentatively identified 260, including monomers, additives, and nonintentionally added substances, and prioritized 27 chemicals. Extracts of polyvinyl chloride (PVC) and polyurethane (PUR) induced the highest toxicity, whereas polyethylene terephthalate (PET) and high-density polyethylene (HDPE) caused no or low toxicity. High baseline toxicity was detected in all “bioplastics” made of polylactic acid (PLA). The toxicities of low-density polyethylene (LDPE), polystyrene (PS), and polypropylene (PP) varied.

Our study demonstrates that consumer plastics contain compounds that are toxic in vitro but remain largely unidentified.

Since the risk of unknown compounds cannot be assessed, this poses a challenge to manufacturers, public health authorities, and researchers alike. However, we also demonstrate that products not inducing toxicity are already on the market.
