It also provides links to access and download relevant datasets and some example R code for data processing and modeling.Post phytoremediation accumulation of heavy metals in plants is causing an environmental issue worldwide. In this study, we investigated the ability of eight different kinds of microorganisms to degrade and release heavy metals from heavy metal enriched ryegrass, including 5 species of bacteria (Bacillus subtilis, Bacillus licheniformis, Bacillus pumilus-I, Bacillus pumilus-II and Bacillus cereus) and 3 of fungi (Phanerochaete chrysosporium, Trichoderma ressei and Pterula sp. strain QD-1), by growing them under uranium stress and assessing their ability to degrade biomass. After 30 days, the degradation ability of fungi was found better than that of bacteria, while the metal leaching ability of bacteria was found better. The highest degradation rate (upto 60%) was obtained by using P. chrysosporium, Pterula sp. strain QD-1 exhibited the best leaching rate for uranium (upto 77%). The overall degradation rate of lignin and cellulose and hemicellulose was found lower (40% and 60%, respectively). selleckchem According to the antagonistic characteristics of microbes, we combined different dominant species, in which under optimal conditions the T2 combination (P. chrysosporium, T. reesei, and Pterula sp. strain QD-1 and B. subtilis) was able to degrade 80% of the ryegrass, 51% of lignin, 74% of cellulose and hemicellulose, releasing 78% of U, 90% of Pb and the releasing rate of other heavy metals was more than 95%. FTIR analysis showed the least degradation of lignin, while SEM-EDX analysis of the degradation residues displayed the microstructure of ryegrass being greatly damaged. Only a small amount of U was found in the residues of the researched combinations. This study provides efficient Microbial Combined Degradation Technology for heavy metal enriched biomass, which can effectively deal with heavy metal enriched plants, and provide a basis for the recovery and utilization of heavy metals, avoiding secondary pollution in the environment caused by this type of biomass.
To perform an updated and comprehensive meta-analysis on the risks of adverse perinatal outcomes in children whose mothers received antidepressants during pregnancy.

A systematic literature search of several databases was conducted through December 2018 to identify relevant studies. Risk estimates and their corresponding 95% confidence intervals (CIs) were pooled using random-effects meta-analysis. Subgroup and sensitivity analyses were performed to explore the source of heterogeneity and test the robustness.

Forty-eight cohort and 6 case-control studies were included. In cohort studies, children whose mothers received antidepressants during pregnancy had higher risks of preterm birth (RR = 1.62, 95% CI 1.37, 1.90), low birth weight (RR = 1.37, 95% CI 1.04, 1.80), and admissions to neonatal intensive care unit (RR = 1.60, 95% CI 1.38, 1.85) when compared with children born by depressed but untreated pregnant women. The risks of spontaneous abortions (RR = 1.49, 95% CI 1.29, 1.73), large for gestational age (RR = 1.11, 95% CI 1.03, 1.20), stillbirths (RR = 1.16, 95% CI 1.02, 1.32), low Apgar score at 5 min (RR = 1.91, 95% CI 1.42, 2.56), and neonatal convulsions (RR = 1.97, 95% CI 1.56, 2.48) increased in children whose mothers received antidepressants during pregnancy when compared with children born by healthy pregnant women.

Compared with children whose mothers did not receive antidepressants during pregnancy, children whose mothers received antidepressants during pregnancy had increased risks of adverse perinatal outcomes. Further research on the dose of antidepressants is needed.

A major challenge for the scientific community is to identify, quantify and characterize the sources of atmospheric particles in the aspect of proposing effective control strategies. In the frame of ICARUS EU2020 project, a comprehensive database including PM2.5 concentration and chemical composition (ions, metals, organic/elemental carbon, Polycyclic Aromatic Hydrocarbons) from three sites (traffic, urban background, rural) of five European cities (Athens, Brno, Ljubljana, Madrid, Thessaloniki) was created. The common and synchronous sampling (two seasons involved) and analysis procedure offered the prospect of a harmonized Positive Matrix Factorization model approach, with the scope of identifying the similarities and differences of PM2.5 key-source chemical fingerprints across the sampling sites. The results indicated that the average contribuzed as relatively homogenous among the sites.Heavy metal pollution of marine sediments has attracted a great deal of attention because of its persistence, bioaccumulation, and toxicity. To evaluate the effects of mega-tsunami, anthropogenic activities, and redox conditions on heavy metal accumulation in coastal areas, sediments from Matsushima Bay, Miyagi Prefecture, Japan, were sampled to test variations in heavy metal spatial distribution on the bay floor during 4 years following the 2011 Tohoku Earthquake tsunami. Cluster analysis and principal component analysis were performed to assess the influencing factors and potential sources of heavy metal enrichment in the sediments of the bay. Additionally, the sediment enrichment levels of heavy metals were assessed on the basis of the enrichment factor (EF). The results of multivariate statistical analyses showed that the Ti, Fe, V, Pb, and Zn contents in Matsushima Bay sediments, which were transported mainly from Sendai Bay, depended on the mud content. The value of EF 3 for Mn and As indicated moderate to severe contamination with these heavy metals in the bay mouth area during 2015.
