Application and Selection of Remediation Technology for OCPs-Contaminated Sites by Decision-Making Methods

Abstract

The production and use of organochlorine pesticides (OCPs) for agricultural and industrial applications result in high levels of their residues, posing a significant risk to environmental and human health. At present, there are many techniques for OCP-contaminated soil remediation. However, the remediation of contaminated sites may suffer from a series of problems, such as a long recovery cycle, high costs, and secondary pollution, all of which could affect land redevelopment and reuse. Therefore, the selection of an appropriate technology is crucial for contaminated sites. In order to improve and support decision-making for the selection of remediation techniques, we provide a decision-making strategy for the screening of remediation techniques of OCP-contaminated sites. The screening procedure is proposed based on combining the analytic hierarchy process (AHP) and the technique for order preference by similarity to ideal solution (TOPSIS). The screening indexes include economic indicator, environmental indicator, and technical indicator. The assessment results show that co-processing in cement kiln obtained the highest overall score and was thus considered to be the most sustainable option. This suggested remediation technology was similar to the practical remediation project, indicating that the screening method could be applied for the selection of remediation technologies for sites contaminated with persistent organic pollutants.

Seasonal Changes in Pesticide Residues in Water and Sediments from River Tano, Ghana

“…In spite of the ban on the use of OCP by the Stockholm convention, they are illegally used in some developing countries making the ban ineffective [ 21 ]. For example, about 4.99 × 10 6 tons of OCPs are produced and distributed annually for agricultural purpose in China [ 22 , 23 ]. In the year 2014, China alone consumed about 1.8 million tons of pesticide, Argentina consumed about 200 thousand tons of pesticides, USA consumed 125,000 tons, India consumed 110,000 tons, and Mexico consumed 98,000 tons [ 24 ].…”

Research on Investment Environment Performance Evaluation of Blockchain Industry with Intuitionistic Fuzzy CODAS Method

“…Future research could tackle the interdependency of attributes by utilizing some other methods including ANP, AHP, and information entropy. Furthermore, the developed method could be used to tackle some other MAGDM like project selection [50][51][52][53][54] and site selection [55][56][57]. It could also be applied to some other diverse uncertain and ambiguous settings [58][59][60][61][62][63][64][65][66].…”

A Soil Environmental Quality Assessment Model Based on Data Fusion and Its Application in Hebei Province

“…The hierarchical analysis model is shown in Figure 2. There are several methods that can be used for calculating weights in the DPSIR model, such as the AHP method [32,33], the Delphi method [34], the coefficient of variation method [35], the entropy weight method [36], and the principal component analysis method [37]. When using the entropy weight method or the principal component analysis method, we need to know the values of each indicator before calculating the weights; however, this is not realistic in our application.…”
