Identification of some plasticizers compounds in landfill
These methodologies allow the isolation and identification of the following compounds: dioctylphthalate, diisobutilphthalate, BPA, benzoic acid, palmitic acid and diisopentylphthalate. The methods are very simple, rapid and selective, for plasticizers extraction from landfill leachate matrices. Introduction
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.

Identification of some plasticizers compounds in landfill
In this work it was described a simple method for extraction of plasticizer compounds (mainly phthalate esters and bisphenol A (BPA)) from landfill leachate samples. The samples were submitted to an extraction procedures based on precipitation, solid phase extraction (SPE) and ionic exchange chromatography (IEC). Firstly the landfill leachate sample was acidified by addition of HCl
Simultaneous determination of phthalate esters and
Furthermore, environmental risk assessments of CEC compounds in treated landfill leachate using a risk quotient method show that 2 (substituted) polycyclic aromatic hydrocarbons (sPAHs)...
- Is landfilling a common method for utilizing plastic waste at its end-of-life?
- 8. Conclusions As landfilling is a common method for utilizing plastic waste at its end-of-life, it is important to present knowledge about the environmental and technical complications encountered during plastic disposal, and the formation and spread of ...
- What type of microplastics are found in landfill leachate?
- The size of 77.48% of the microplastics was between 100 to 1000 μm. According to Xu et al. , the abundance of target MPs in raw landfill leachate was 291 ± 91 particles/L. PP (40%), PA (36%), and rayon (18%) were the main types of MPs that were detected, while PP, polyester PET, and other kinds of MPs were also found occasionally.
- What causes microplastics in landfill leachate?
- The microplastics in landfill leachate originated mainly from the breakdown of different kinds of plastic products, and thus the proportion of plastic fibers is influenced by the amount of plastic fiber products that are landfilled .
- How are MPs produced in landfills?
- Plastic waste around active and former landfills remains a source of MPs. The landfill output consists of leachate and gases created by combined biological, chemical, and physical processes. Thus, small particles and/or fibers, including MPs, are transported to the surroundings by air and by leachate.
- What are the possible pathways for plastic loss from landfills?
- Potential Pathways for the Transfer of Plastic Debris from Landfills to the Environment The possible pathways for plastic losses from landfills encompass environmental processes, including mechanisms such as wind, flooding, leaching, and runoff, and the influence of biota, including their removal by animals.
- Does plastic decompose in a municipal solid waste landfill?
- They described a 12-month decomposition process in a municipal solid waste landfill. During this time, the PE with the additive and plastic waste labelled as 100% degradable had not decomposed, and no physical changes had occurred; however, their colour had changed slightly and the plastic waste exhibited minor surface changes.
