It was observed an enhancement of photodegradation reaction of methylene blue (MB) and paracetamol (PC). For example, when the content of TiO2 increased from 30 to 80% (wt./wt.), the efficiency increased from 58 to 99% (for MB) and 39 for 80% (for PC) under UV (λ = 254 nm). The reactions carried out with solar radiation showed 56 to 95% efficiency to discolor MB. In addition, the results of sedimentation kinetics and characterization confirmed the goals of the synthesis.The impacts of vegetation cover changes (VCCs) and land use land cover changes (LULCCs) on climate variabilities need to be addressed while maintaining healthy urban development. This study aimed to evaluate LULCCs and VCCs and their impacts on land surface temperature (LST) and rainfall in the Darbhanga district of Bihar, India. Landsat data and climate hazard group infrared precipitation with stations (CHIRPS) were used to assess LST or LULCCs and rainfall, respectively, over the study area. Results showed a decline in vegetation cover to 11.73% (26,857.43 ha) in the year 2019 from 19.12% (43,733.61 ha) in 1999. Also an increase in built-up and cropland by 4.9% (11,224.6 ha) and 4.38% (10,043.2 ha), respectively, was observed in the last 20 years. With decreasing vegetation cover in the study area, the mean LST increased while the mean annual rainfall decreased for the study period. The Mann-Kendall trend (MKT) test exhibited no significant trends for LST and rainfall with p values of 0.43 and 0.69, respectively, although Sen's slope indicated variability in LST and rainfall even though it was insignificant over the study area. The study would identify areas requiring immediate action for saving its resources and providing insight into upholding its competence. The findings would also lead to proper decision making for the concerned stakeholders, assuring sustainability in appropriate planning of land use and utilisation of resources and maintain the agroclimatic condition.In recent times, the persistent global environmental challenges have paved the way for the underpinning of climate change within the perspective of financial performance. Given this motivation, the current study further examines the interaction of foreign direct investment, fiscal development, renewable energy usage, economic growth, and CO2 outrush of South Africa (1970 to 2014). The unit root test of Zivot-Andrews and augmented Dickey-Fuller (ADF), vector autoregressive (VAR), and Pesaran ARDL (autoregressive distributed lag bounds) approach were employed in the data analysis. The existence of a statistically significant correlation among the series was detected by the Johansen multivariate cointegration in long term and subsequently by the long run coefficient of the vector error correction model test result. Furthermore, in the long run, significant positive correlation existed among renewable energy, GDP (economic growth), development in finance (FD), and CO2 outrush. https://www.selleckchem.com/products/Dexamethasone.html While in the short run, GDP and development in finance have a statistically positive correlation with outrush of CO2; renewable energy consumption exerts a negative relationship on CO2 in the short run. The Granger causality results show overall causality among the series; proof of bidirectional stimulus running from renewable energy to economic growth; foreign direct investment to trade; and also one causality direction running among the other variables. The policy twist is that the implementation of energy efficiency programs currently pursued by the South African government to enhance renewable energy consumption should be facilitated with more determination. In addition, the government and policymakers should thrive to align these energy efficiency programs with other macroeconomic and financial variables such as foreign direct investment (FDI), fiscal development, and trade openness to achieve minimum CO2 outrush level in South Africa, thus yielding environmental sustainability.Water quality is one of the most important indices for public health especially for drinking water consumptions. This study was conducted to survey the presence of heavy metals in drinking water resources of Iran using a systematic review and meta-analysis. The literature search was conducted in data bases of PubMed, Web of Science, EMBASE, Scopus, Google Scholar, and some Persian databases up to 31 July 2018. Of all the articles reviewed (1151 articles), 61 papers were eligible for systematic review. Results indicated variable heterogeneity between studies for different pollutants (I2 between 0 and 100). A subgroup analysis was performed for three different types of water resources such as drinking water, groundwater, and surface water to find the possible source of the heterogeneity. The pooled mean concentration level of iron was the highest at 255.8 (95% CI = 79.48-432.13 μg/l) and vanadium the lowest at 3.21 (95% CI = 1.45-4.98 μg/l). The sequence of metal concentration (μg/l) in descending order is as follows Fe (255.8) > B (159.81) > Al (158.5) > Zn (130.73) > As (85.85) > Mn (51.61) > Cu (47.98) > Se (42.68) > Pb (37.22) > Co (22.76) > Mo (18.92) > Ni (16.79) > Cr (13.47) > Hg (4.49) > Cd (4.19) > V (3.21). The mean pooled concentration level of Al, As, Se, Pb, and Cd was higher than the WHO guideline and Iran Standard, and the rest of the metals had lower mean pooled concentration level. Pb and Cd were the common heavy metals that existed in all subgroups. As a recommendation, the relationship assessment of water parameters and heavy metals could be addressed in future studies of Iran's water resources.The present study evaluates the development of visible injury related to phytotoxic ozone dose (PODy) in native tropical species Astronium graveolens Jacq. (Anacardiaceae) and validates the symptoms using structural markers attributed to oxidative burst and hypersensitive responses. Increasing POD0 was associated with increasing O3 visible injury using different metrics as the incidence (INC = number of injured plants/total number of plants × 100), severity (SF = number of injured leaves/total number of leaves on injured plant × 100), and severity leaflet (SFL = number of injured leaflets/total number leaflets injured plant × 100). The effective dose (ED), which represents the POD0 dose responsible for inducing 20 (ED20), 50 (ED50), or 80% (ED80) of visible injury, were used to demonstrate that for this species, the response is similar even when the plants are exposed to diverse climate environments. Further investigation of the INC and SF index may help in long-term forest monitoring sites dedicated to O3 assessment in forests, while the SFL index seems to be an excellent indicator to be used in the short term to investigate the effects of O3.
