The concentration and spatiotemporal distribution of brominated flame retardants (BFRs), including hexabromocyclododecane (HBCD) and tetrabromobisphenol A (TBBPA), were analyzed in bivalves from Fujian southern coastal areas. The concentrations of HBCD and TBBPA ranged from ND (not detected) to 5.540 ng·g-1 (ww) (median of 0.111 ng·g-1) and ND to 0.962 ng·g-1 (ww) (median of ND), respectively. In addition, α-HBCD was found as the predominant diastereoisomer in all the studied samples, followed by β-HBCD and γ-HBCD. The spatial distribution of BFRs showed a peak distribution, with the content being higher in the marine environment of Xiamen and Quanzhou, in South Fujian, and lower toward the marine environment of Zhangzhou, and Putian. BFRs contamination level was correlated to the bay geographical location and proximity to local industries. Furthermore, the results of the study showed a seasonal variation pattern summer > autumn > spring > winter. This study provides base information on the contamination status of these BFRs in the marine environment of southern Fujian.Carbon neutral is among the possible ways of solving the problem of climate change. STAT inhibitor Many scholars have utilized different single indicators such as CO2 and methane with different variables to mitigate the possible ways of solving the problem of global warming. The present study employs a specific country (UAE) approach to investigate the possible way of solving climate change. The author utilized 1980-2018 annual data of the UAE to investigate the possibility of carbon neutral in the UAE as to suggest ways of limiting climate change. Both linear and non-linear (squared) foreign direct investment (FDI) and GDP per capita were added to the study and considered as the variables of interest and other control variables (energy use and population). Among the findings of this study are inverted U-shaped relationship between economic growth (GDP per capita) and ecological footprint which confirms EKC for the UAE, positive relationship between energy use and ecological footprint, negative relationship between FDI and preventive in nature towards FDI so as to maintain this positive trend towards sustainable development. The analytical abstract demonstrates the interactions that exist among the employed variables in Granger causality analysis. The big arrows denote two-way transmission while the small arrows show one-way causal transmissions passing to the variables where they are pointing at.Environmental arsenic exposure in adults and children has been associated with a reduction in the expression of club cell secretory protein (CC16) and an increase in the expression of matrix metalloproteinase-9 (MMP-9), both biomarkers of lung inflammation and negative respiratory outcomes. The objectives of this study were to determine if the levels of serum CC16 and MMP-9 and subsequent respiratory infections in children are associated with the ingestion of arsenic by drinking water. This cross-sectional study included 216 children from three Yaqui villages, Potam, Vicam, and Cocorit, with levels of arsenic in their ground water of 70.01 ± 21.85, 23.3 ± 9.99, and 11.8 ± 4.42 μg/L respectively. Total arsenic in water and urine samples was determined by inductively coupled plasma/optical emission spectrometry. Serum was analyzed for CC16 and MMP-9 using ELISA. The children had an average urinary arsenic of 79.39 μg/L and 46.8 % had levels above of the national concern value of 50 μg/L. Increased arsenic concentrations in drinking water and average daily arsenic intake by water were associated with decreased serum CC16 levels (β = - 0.12, 95% CI - 0.20, - 0.04 and β = - 0.10, 95% CI - 0.18, - 0.03), and increased serum MMP-9 levels (β = 0.35, 95% CI 0.22, 0.48 and β = 0.29, 95% CI 0.18, 0.40) at significant levels (P less then 0.05). However, no association was found between levels of these serum biomarkers and urinary arsenic concentrations. In these childr
