Identification of some plasticizers compounds in landfill
As plasticizers are compounds of hard microbial decomposition, the common treatment applied to the landfill leachate is not able to eliminate them. In this way, plasticizers can persist in the environment and contaminate superficial and groundwater. It is estimated that from 90% to 95% of the organic materials in municipal landfill leachate are
Preliminary study of some plasticizers compounds in sewage
As plasticizers are compounds of hard microbial decomposition, it is very probable that the common treatment applied to the sewage (independently of the source, domestic or industrial plants) it is not able to reduce their concentrations to safe levels, before the discard into superficial waters.

Abstract In this work it was described the extraction and analysis of plasticizers compounds, namely: dioctylphthalate (DOP) and diisobutylphthakate (DBP) in samples of liquid residues of the...
Identification of some plasticizers compounds
The highest concentrations were found for two plasticizers (bisphenol A and di(2-ethyhexyl)phthalate, mean concentration up to 930 ng/L) and two pharmaceutical compounds (caffeine (up to 623 ng/L

- Do microplastics and plasticizers exist in municipal wastewater treatment plants?
- Microplastics (MPs) and plasticizers, such as phthalate esters (PAEs), were frequently detected in municipal wastewater treatment plants (MWTP). Previous research mainly studied the removal of MPs and PAEs in wastewater. However, the occurrence of MPs and PAEs in the sludge was generally ignored.
- Are plasticizers a priority pollutant?
- Plasticizers can persist during the treatment of wastewaters in sewage treatment plants (STPs) and can be discharged in effluents and/or accumulated in sewage sludges. For example, di-2-ethylhexyl phthalate (DEHP) is a common plasticizer that is nowconsidered a priority pollutant and is known to accumulate in sludges.

- Does biodegradation of plasticizers cause toxic metabolites?
- Recently, it was demonstrated in studies with pure cultures that the biodegradation of plasticizers including DEHP and di-ethylhexyl adipate (DEHA)generates toxic metabolites including 2-ethylhexanoic acid, 2-ethylhexanol, and 2-ethylhexanal.
