“…For non-carcinogenic risk, the concentrations of TCPP, EHDPP and TiBP were the most influential variables, which contributed 53.17, 23.66 and 14.05% of the total variance of non-carcinogenic risk assessment for adults respectively, and contributed 52.6, 25.14 and 13.34% of the total variance of noncarcinogenic risk assessment for children respectively. The results were similar to the previous studies about other pollution, which suggested that the concentration of pollution is the most sensitive parameter in risk assessment [36]. Thus, controlling the concentration of OPEs, especially TCEP, TCPP, EHDPP and TiBP, is the most effective way to mitigate health risk.…”

Organophosphate esters (OPEs) are a class of synthetic chemical additives that as the primary substitute of polybrominated diphenyl ethers (PBDEs) have been extensively used as flame retardants and plasticizers in various commercial products [1]. Due to OPEs not bonding chemically to the finished products, they are easy to release into the surrounding environment through abrasion, volatilization and leaching. In recent years, OPEs have been ubiquitously found in all kinds of environmental media (water, sediment, soil, etc.) and living organisms [1-3], plus in blood, breast milk and placenta for different concentration levels [4]. However, OPEs are not safe and are potentially harmful to the ecosystem and humans. Thus far, most OPEs have been proven to induce toxicity effects on

“…Meanwhile, for the value of recreation and education, distinctions would exist between different coastal wetlands because of geomorphology and tourist attraction etc. [61][62][63][64]. There was no relationship between the value of recreation and education and wetland area, and social-economic characteristics around the wetlands.…”

Addressing the Modelling Precision in Evaluating the Ecosystem Services of Coastal Wetlands

Wetlands are one of the world's most productive ecosystems, and therefore it is crucial that management decisions regarding wetlands incorporate awareness of accurate assessments of the value of their respective ecosystem services. In this paper, we seek to improve the modelling precision in the scale transform process of ecosystem service evaluation. Firstly, we selected eight services as the criteria to calculate wetland ecosystem values: substance production, flood control, carbon sequestration, gas regulation, climate regulation, wave reduction, adding new lands, recreation and education. Then, six coastal wetlands of Liaoning province were chosen as the case study areas, and their ecosystem values were calculated by empirical method. Next, we simulated ecosystem values of the six cases by two spatial-scales transform methods named meta-analysis and wavelet transform. Finally, we compared the two groups of simulated values with the empirical measured values to examine their evaluation precisions. The results indicated that the total precision of the wavelet transform model (0.968) was higher than that of meta-analysis (0.712). In addition, the simulated values of single services such as substance production, flood control, carbon sequestration, gas regulation, and climate regulation were closer to the measured values using wavelet transform model. This research contributes to identifying an evaluation model with higher precision for evaluating wetland ecosystem services in the process of scale transform.

“…The dose values calculated in urban and semi-urban areas for adults are given in Table 1. The risk of cancer was determined by multiplying the dose of exposure by inhalation, and the potential factor of cancer is given in Table 2 [29,30]. It is necessary to multiply 10 6 by calculating the probability of the estimated cancer risk in a million cancer.…”

Air pollution is one of the factors that has a significant impact on human health, especially in many developing countries. In this study, polycyclic aromatic hydrocarbon (PAH) levels and cancer risk caused by inhalation were determined in an urban (Ovaakca) and a semi-urban (Cumalikizik) sites in Bursa, Turkey's 4th largest city. In this context, this research was carried out between May 2017-September 2017 (beekeeping period), with passive air sampling and honeybee media. Sampling was carried out in two weeks intervals during the beekeeping period. The mean ∑14PAH concentration values, obtained by polyurethane foam (PUF) disk media during the sampling period, was 198.62±24.93 ng m-3 in the Ovaakca site, while in the Cumalikizik site was 445.47 ± 59.21 ng m-3. The lowest PAH concentration in PUF disc media was measured in Ovaakca region, and the highest concentration was measured in Cumalikizik region in June. Similarly, the total ∑13PAH concentration obtained in the honeybee media during the sampling period was 380.87 ± 115.33 ng g-1 dw for the Ovaakca sampling site, and 217.96±30.10 ng g-1 dw for the Cumalikizik sampling site. The highest concentration level in the honey bee media in the Ovaakca region and the lowest concentration level in Cumalikizik site were measured in September. Inhalation cancer risk was determined for adults (70 years) using PUF disc media concentration values. It is seen that the Cumalikizik site located next to the picnic area had a higher risk of cancer. Both compounds, Benzo[a]pyrene (BaP) and Benzo[a]anthracene (BaA) are the most common species used to determine cancer risk.
