“…Previous studies also indicate that PM 2.5 and PM 10 also have detrimental impact on mental health. For instance, depression has been reported by a bulk of literature to be closely correlated with PM 2.5 [28][29][30][31][32][33][34]. Importantly, depression is a primary risk factor for suicide [35][36][37][38].…”

Background: Suicidal ideation is subject to serious underestimation among existing public health studies. While numerous factors have been recognized in affecting suicidal thoughts and behaviors (STB), the associated environmental risks have been poorly understood. Foremost among the various environment risks were air pollution, in particular, the PM2.5. The present study attempted to examine the relationship between PM 2.5 level and local weekly index of suicidal ideation (ISI). Methods: Using Internet search query volumes in Baidu (2017), the largest internet search engine in China, we constructed a prefectural panel data (278 prefectures, 52 weeks) and employed dynamic panel GMM system estimation to analyze the relationship between weekly concentration of PM2.5 (Mean = 87 μg·m − 3 ) and the index of suicidal ideation (Mean = 49.9). Results:The results indicate that in the spring and winter, a 10 μg·m − 3 increase in the prior week's PM 2.5 in a Chinese city is significantly associated with 0.020 increase in ISI in spring and a 0.007 increase in ISI in winter, after taking account other co-pollutants and meteorological conditions. Conclusion:We innovatively proposed the measure of suicidal ideation and provided suggestive evidence of a positive association between suicidal ideation and PM 2.5 level.

“…In our research we have particularly used AgNPs while other nanoparticles can be investigated too, for example CuO-NPs are far more interesting in terms of toxicity, or the most widespread NPs are those using TiO 2 , and the most prominent candidate in terms of neuro-toxicity are Al-compounds that comodulate neurodegenerative diseases 77 . As a future prospect, it can be studied too whether our research can be connected to chronic atmospheric NP-exposure and translocation of ambient NPs via the BBB or the olfactory pathway directly into the brain 78 along with the associated neuro-degenerative effects 79 ? In theory such effects must also have an impact on the epigenome of NSCs 80 .…”

neurons like other living cells may have ultraweak photon emission (Upe) during neuronal activity. this study is aimed to evaluate Upe from neural stem cells (nSc) during their serial passaging and differentiation. We also investigate whether the addition of silver nanoparticles (AgNPs) or enhancement of UPE (by AgNPs or mirror) affect the differentiation of NSC. In our method, neural stem and progenitor cells of subventricular zone (SVZ) are isolated and expanded using the neurosphere assay. the obtained dissociated cells allocated and cultivated into three groups: groups: i: cell (control), ii: cell + mirror, and iii: cell + Agnps. After seven days, the primary neurospheres were counted and their mean number was obtained. Serial passages continuous up to sixth passages in the control group. Differentiation capacity of the resulting neurospheres were evaluated in vitro by immunocytochemistry techniques. Measurement of Upe was carried out by photomultiplier tube (pMt) in the following steps: at the end of primary culture, six serial cell passages of the control group, before and after of the differentiation for 5 minutes. The results show that neither mirror nor AgNPs affect on the neurosphere number. The UPE of the NSC in the sixth subculturing passage was significantly higher than in the primary passage (P < 0.05). AgNPs significantly increased the UPE of the NSC compared to the control group before and after the differentiation (P < 0.05). Also, the treatment with AgNPs increased 44% neuronal differentiation of the harvested NSCs. UPE of NSC after the differentiation was significantly lower than that before the differentiation in each groups, which is in appropriate to the cell numbers (P < 0.0001). The mirror did not significantly increase UPE, neither before nor after the differentiation of nSc. As a conclusion, nSc have Upe-properties and the intensity is increased by serial passaging that are significant in the sixth passage. The AgNPs increases the UPE intensity of NSC that pushes more differentiation of NSC to the neurons. The mirror was not effective in enhancement of UPE. As a result, UPE measurement may be suitable for assessing and studying the effects of nanoparticles in living cells and neurons.

“…The harmful physical health sequalae of these emissions are well-recognised [4][5] . In comparison, understanding of the mental health effects of pollution is emergent [6][7][8] , particularly when it comes to impacts on children and adolescents [9][10] . The under-attention to pollution's potential mental health effects is problematic, not least because much of the global burden of disease is attributable to mental illness 11 .…”

Background Whilst there is little uncertainty about the deleterious impact of pollution on human and planetary health, pollution’s impact on child and adolescent mental health is less well understood. This is particularly true for young people in underdeveloped and developing world contexts, about whom research is generally lacking. Furthermore, although child and adolescent resilience continues to be a research priority, little attention has been paid to child and adolescent pathways of resilience in the face or aftermath of pollution exposure. Methods We will conduct a systematic review that adheres to PRISMA guidelines. Its purpose is to document what is known about how pollution affects child and adolescent mental health, along with what protects children and adolescents against these effects and associations across diverse contexts. Discussion Systematic insights are likely to support psychologists and other mental health practitioners to better support child and adolescent wellbeing globally regardless of exposure to pollution. Systematic review registration We have registered the review protocol in PROSPERO (registration: CRD42020176664).
