  • Is DEHT a class ECOTOX?
  • nictitating membrane. At 48 hours after exposure all animals appeared normal. Following GHS criteria, DEHT is not class Ecotoxicity (Ecotox)Acute Aquatic Toxicity (AA) Score (vH, H, M or L): LDEHT was assigned a score of Low for acute ased on no effects being expected at saturation levels of DEHT. ECHA 2012 –A
  • Does DOTP biodegradation affect microbes?
  • This study assessed the biodegradation and toxicity of DOTP on microbes, focusing on its impact on biofilms and microbial metabolism using Rhodococcus ruber as a representative bacterial strain. DOTP is commonly found in mass fractions between 0.6 and 20% v/v in various soft plastic products.
  • Does DOTP undergo hydrolysis when interacting with biodegrading microbes?
  • It was found that DOTP can undergo hydrolysis when interacting with biodegrading microbes, producing breakdown products. Remarkably, these products were detected even without an additional carbon source, implying potential biodegradation by R. ruber.
  • Does DOTP affect microbial communities?
  • An increase in the volume of dead cells (in the plastisphere biofilm) was observed with increasing DOTP concentrations in experiments using PVC films, indicating the potential negative impact of DOTP on microbial communities.
  • What is a low concentration of DOTP?
  • Although DOTP is found in concentrations between 0.6 and 20% in most products, these findings suggest that concentrations of DOTP exceeding 5% may compromise its viability, and even at lower concentrations like 1%, signs of stress were observed.
  • Is DEHT biodegradable?
  • 73.05% biodegradation within 28 days and met the 10-day bio DEHT was reported as readily biodegradable by study authors. UNEP 2003 – A (GLP status not reported) 28-day shake flask biodegradation test (similar to OECD 301 B) was conducted under aerobic conditions at a concentration of 1.04 mg/L. DEHT was found to have 40.2%
