“…4c). The anti-DP concentrations (Range ¼ BDL-63.10 ng/g, Mean ¼ 2.70 ng/g) were the leading ones followed by syn-DP (Range ¼ 0.00e22.90 ng/g, Mean ¼ 2.00 ng/g) in the dust (indoor and outdoor) of different zones that was concurrent with the results of Tao et al (2015) in the soil samples. The results of Li et al (2015) in indoor house dust in China are also in close agreement with our results.…”

“…These products for their prompt merchandise innovation, oldness and to cope with sale demand for peoples of developing countries, most of the aforementioned consumer products were discarded within a three-year duration from the date of purchase. All these functionless products due to their low life span are going to increase day by day as a waste stream of dump (Tao et al, 2015). Currently, majority of e-waste generated in developed countries are exported for recycling purposes to the developing countries viz., India, China and Pakistan (Lundgren, 2012).…”

In reverse logistics, the accurate prediction of waste electrical and electronic equipment (WEEE) return amount is of great significance to guide electronic enterprises to formulate a reasonable recycling plan, remanufacturing production plan and inventory plan. However, due to the uncertainty of WEEE return, it is a challenge to accurately predict the WEEE return amount of recycling sites. Differently from the existing research methods aiming at the spatial correlation of the recycling amount of recycling sites, a spatial mathematical model based on Kriging method is proposed by this paper to predict the return amount of WEEE in reverse logistics. Based on the second-order randomness of the return amount, the spatial structure of the return amount of the recycling network is analyzed. According to the principle of unbiased prediction and minimum variance, the Kriging space mathematical model of WEEE return amount is derived, and the calculation process of three variograms is given. The results of Monte Carlo simulation and the case study on J company in Shanghai show that it is effective to utilize the Kriging method-based spatial mathematical model to predict the WEEE return of reverse logistics and analyze the spatial correlation structure of each recycling site. The proposed model can accurately predict the WEEE return amounts of unknown sites as well as those of the whole area through the known site data, which provides a novel analysis method and theoretical basis for the prediction of reverse logistics return amount.

“…Dechlorane Plus (DP) is a polychlorinated flame retardant designed to replace Brominated flame retardants or Mirex (Ji et al, 2018 ), and it is widely used in plastic roofing materials, electrical wires, hard disk connectors of computers, and other polymeric systems (Ren et al 2008). DP is found common in the aquatic environment Sun et al 2017;Tao et al 2015;Wu et al 2016), with a half-life of about 24 years in the water environment. It is a typical persistent organic pollutant and has an effect of bio-enrichment and bio-fortification in the biota (OxyChem 2007;Yu et al 2013).…”

Dechlorane Plus (DP) is a widely using chlorinated flame retardant, and has been detected extensively in the environment. Even though the DP content in the surface water is low, it can pose a continuous exposure risk to aquatic organisms due to its strong bioaccumulation. Since related researches on the toxicity mechanism of DP exposure on carp embryo development are limited, we carried out the evaluation of DP effect on carp. In this study, Carp embryos were exposed to DP of 0, 30, 60, and 120 µg/L at 3h post fertilization (hpf). The expression of genes associated with the neural and skeletal development such as sox2, sox19a, Mef2c, and BMP4 were evaluated using quantitative PCR (qPCR), and analysis of different developmental toxicity endpoints changes were observed with microscopy. Our results demonstrated that the expression of sox2, sox19a, Mef2c, and BMP4 were significantly changed and several developmental defects were observed in the exposed carps embryo, such as DNA damage, increased mortality rate, delayed hatching time, decreased hatching rate, decreased body length, increased morphological deformities. In addition, reactive oxygen species (ROS) and malondialdehyde (MDA) were significantly increased with DP exposure at 60µg/L and 120 µg/L. Altogether, our results suggest that DP may have an unique modes of action, which results in aberration occurrence in the early development stage of common carps, that may relates to some gene damage and oxidative stress. Besides, the parameters evaluated here can be used as tools to access the environmental risk for biota and humans exposed to DP.
