Environmental disasters |The first scientific analysis of the pellets reveals substances that the report commissioned by the Xunta hid - El Salto - Galiza

The first scientific and independent analysis of the pellets that have put the northwest coast of the peninsula in check reveals substances that the report commissioned by the Xunta de Galicia had hidden.Although it was expected, it is no less relevant.Especially, taking into account that the work commissioned by the Ministry of Environment of Ángeles Vázquez (PP) to the Technological Center for Multisectorial Research (Cetim) was only based on the technical prescription of the pellets provided by the manufacturer and not on an analysis of laboratory to a sample collected on Galician beaches.

The results of the report, freely accessible to anyone, confirm the majority presence of Tinuvin (UV622), an ultraviolet light stabilizer, and 14 other substances that go beyond the classification as polyethylene, the most abundant plastic, which made officially the Galician Government of the Popular Party.

The research work was born within the Universidade da Coruña, outside of any political control.Specifically, from the Applied Analytical Chemistry research group following some samples collected on Nemiña beach, in Muxía (A Coruña), one of the places on the Costa da Morte most affected due to the currents of the Atlantic Ocean, just as happened during the Prestige oil tanker disaster.

Beyond the composition based on polyethylene already mentioned in the brief report published by the Xunta de Galicia commissioned ad hoc from a private company, the researchers from the University of Coruña delve into its chemical additives.The additive found in the highest proportion is Poly (4-hydroxy-2,2,6,6-tetramethyl1-piperidine ethanol-alt-1,4-butanedioic acid), commercially known as Tinuvin 622, manufactured by the multinational chemical company BASF.An element that is used as an amine-based photostabilizer in the manufacture of plastics, that is, a substance derived from ammonia by replacing one or two hydrogen atoms.And although, indeed, its solubility in water is low, the manufacturer itself recognizes that it is “moderately toxic to aquatic organisms.”

In addition, other amine-based photostabilizers have been identified, to a lesser extent: Tinuvin 123, Tinuvin 120, Sumisorb 400, Seesorb 712, Chemisorb 112, UVCheck AM-340, Sanol LS 770 (Sankyo), ADK STAB LA-77, Mark LA-77, Tomisorb 77, or Tinuvin 770. In addition, other compounds used as chemical additives in the plastic industry have been detected: such as 4-Methylbenzyl alcohol, Dimethyl succinate, Succinic acid anhydride, 2,2,6,6- Tetramethyl-4-piperidinol, 2-Undecanone and other aliphatic ketones.Also 4-tert-Octylphenol, Calcium stearate, Methyl palmitate, Irganox 259, Sanol LS 2626, Irgafos 168, Sumilizer P-16, ADK STAB AO-2112, JP-650 and Alkanox 240.
