The objectives of the present study were to investigate heavy metal accumulation in 22 vegetable species and assess human health risks consumption. Six types cultivated on farmland contaminated with metals (Pb, Cd, Cu, Zn, As). target hazard quotient (THQ) method was used posed by through Clear differences found concentrations edible parts different vegetables. decreased sequence as leafy vegetables > stalk vegetables/root vegetables/solanaceous legume vegetables/melon ability uptake...
Abstract A new data set of seasonal stable water isotopes (δD and δ 18 O) temperature‐salinity profiles was applied to improve our understanding mass distributions their impact on the environment Beibu Gulf (BG). Our study revealed that coastal current (CC), West‐Guangdong (WGCC), South China Sea (SCSW) were three dominant masses in BG, influence exhibited variations. The CC contributor BG during summer (43%) fall (45%), while it changed intrusion SCSW with higher salinity winter (57%)....
Abstract The January 2022 eruption of Hunga Tonga‐Hunga Ha'apai (HTHH) injected a huge amount (∼150 Tg) water vapor (H 2 O) into the stratosphere, along with small SO . An off‐line 3‐D chemical transport model (CTM) successfully reproduces spread H O through October 2023 as observed by Microwave Limb Sounder. Dehydration in Antarctic polar vortex caused first substantial (∼20 removal HTHH from stratosphere. CTM indicates that this process will dominate for coming years, giving an overall...
Abstract Lower Stratospheric water vapor (SWV) is one of important drivers global climate change. Increases and decreases in lower SWV have been found to strengthen offset warming effects, respectively. Using several data sets, we find that sea surface temperature (SST) the past 100 years has caused an increase SWV. SST over tropical Indian Ocean western Pacific resulted a drier stratosphere. However, Atlantic significantly wetter stratosphere main contributor increasing trend years. The...
Abstract The effect of aerosol on liquid cloud microphysical properties over the Tibetan Plateau (TP) during warm season is investigated by using index (AI) and property parameters data. Distinct differences in have been found between northern (NTP) southernTibetan (STP). composite droplet effective radius (LREF) anomalies for positive AI events are NTP negative STP. In both STP, when positive, LREF also which suggests that increased loading reduces solar radiation reaching ground thus...
Soybean is one of most important dicotyledonous food crops and widely planted in Hunan Province, China. However, mining activity causes contamination the soil which soybean grows. To assess impact mining-induced on plants, a geoaccumulation index (I(geo)) was used to evaluate 20 samples from smelting areas southern Province. The results indicated that Zn ranged uncontaminated moderately contaminated level (I(geo)<1), Pb at strongly (I(geo)>3), Cd an extremely (I(geo)>5) across whole study...
Abstract The causes of ENSO diversity, although being great interest in recent research, do not have a consistent explanation. This study provides possible mechanism focused on the background change tropical Pacific as response to global warming. second empirical orthogonal function mode sea surface temperature anomalies (SSTA) Pacific, namely cold tongue (CTM), represents under Using composite analysis with observations and subsurface ocean assimilation data sets, we find spatial structure...
Abstract Time-slice experiments with the Whole Atmosphere Community Climate Model, version 4 (WACCM4), and composite analysis satellite observations are used to demonstrate that Indo-Pacific warm pool (IPWP) can significantly affect lower-stratospheric water vapor. It is found a warmer IPWP dries stratospheric vapor by causing broad cooling of tropopause, vice versa for colder IPWP. Such imprints in tropopause temperature driven combination variations Brewer–Dobson circulation stratosphere...
A systematic method for the optical design and analysis of a multipass cell (MPC) with two spherical mirrors is presented. By varying parameters, including distance between mirrors, position incident point, angles, variety dense patterns can be formed on mirrors. Three MPCs exemplary seven circles, rotating triangles, petals are designed built. We compare analyze parameters each MPC respect to volume, path length (OPL), number reflections, stability final spot position. This new type...
Extreme precipitation events cause severe environmental and societal damage worldwide. Southwest China (SWC) is sensitive to such effects because of its overpopulation, underdevelopment, fragile ecosystems. Using daily observations from 108 rain-gauge stations, the authors investigated frequency extreme their contribution total in SWC since late 1970s. Results indicate that decreasing insignificantly, but rainfall-events significantly, whereas region experiencing more frequent intense...
The Hunga eruption, January 2022, injected ~150 Tg of water vapour into the sub-tropical mid-stratosphere, unprecedented in satellite era. effects on heterogeneous chemistry Antarctic stratosphere did not occur 2022 season, with vortex edge a barrier to transport high southern latitudes, until break-up. Here, we analyse chlorine activation and ozone loss impacts starting 2023 vortex, find these were uniform throughout limited by widespread mid-winter dehydration that occurs each year, mainly...
The 2022 Hunga Tonga-Hunga Ha'apai (HTHH) volcanic eruption injected around 150 Tg water vapor into the stratosphere. Using Microwave Limb Sounder (MLS) measurement, this study provides first evaluation of HTHH-induced stratospheric (SWV) products revealed by ERA5, MERRA2 and M2-SCREAM reanalyses. Results show that ERA5 underestimate SWV mass compared to MLS observations, while shows good consistency not only in magnitude but also transport depletion details. perform well estimation...
