Nitrated polycyclic aromatic hydrocarbons (nPAHs) are ubiquitous environmental pollutants, which exhibits higher toxicity than their corresponding parent PAHs (pPAHs). Recent studies demonstrated that the nPAHs could represent major soil pollution, however the remediation of nPAHs has been rarely reported. In this study, biological, physical, and chemical methods have been applied to remove 1-nitropyrene, the model nPAH, in contaminated soil. A comparative study with pyrene has also been investigated and evaluated. The results suggest that the physical method with activated carbon is an efficient and economical approach, removing 88.1% and 78.0% of 1-nitropyrene and pyrene respectively, within one day. The zero-valent ion has a similar removal performance on 1-nitropyrene (83.1%), converting 1-nitropyrene to 1-aminopyrene in soil via chemical reduction and decreasing the mutagenicity and carcinogenicity of 1-nitropyrene. Biological remediation that employs scallion as a plant model can reduce 55.0% of 1-nitropyrene in soil (from 39.6 to 17.8 μg/kg), while 77.9% of pyrene can be removed by plant. This indicates that nPAHs might be more persistent than corresponding pPAHs in soil. It is anticipated that this study could draw public awareness of nitro-derivatives of pPAHs and provide remediation technologies of carcinogenic nPAHs in soil.

Objective: to develop a personalized rehabilitation program for improving age-related resilience (AR), antioxidant status (AOS), the quality of life and reducing pain in elderly patients with osteoarthritis (OA).Patients and methods. The program consisted of two parts. In the first part, we conducted a comparative study to assess the AR (Mahnach test), geriatric status, and AOS (amperometric flow-injection analysis) in 181 subjects in total, with coxarthrosis (n=92) and without it (n=89). The average age of patients in two groups was comparable: 72.1±1.1 and 71.9±1.1 years. Using factor analysis, we developed the personalized rehabilitation program based on the obtained data. The effectiveness of the program was evaluated in the second part of our work. We conducted an additional comparative study of changes in AR, AOS, severity of joint pain (by visual analogue scale, VAS) and quality of life (according to SF-36 questionnaire) in patients with coxarthrosis (n=114).Results and discussion. Patients with coxarthrosis had significantly lower level of AR, total antioxidant, and antiradical activity, and a higher content of Schiff bases as compared to subjects without coxarthrosis (p<0.05). The program of rehabilitation, which included a course of treatment with Chondroquard, significantly improved AR, AOS, quality of life and reduced hip pain compared to the standard OA therapy (p<0.05).Conclusion. The personalized rehabilitation program has a complex positive effect on pain, quality of life, AR and AOS in elderly patients with OA.
