... Metals, many of which are potentially toxic, are present in the aquatic environment originated from both natural and anthropogenic sources. In these ecosystems, these elements are mostly deposited in the sediment, followed by water dissolution, potentially contaminating resident biota. Among several aquatic animals, crustaceans are considered excellent bioindicators, as they live in close contact ...
... Elevated sediment-bound trace elements and iron-bearing minerals in intertidal habitats have been drawing more attention, but there is rarely a comparative study assessing these features between halophyte plants habitat and mudflats. In this paper, sediment samples were collected in S. alterniflora and the corresponding mudflat at 7 typical intertidal habitats (Chongming, Xiapu, Yueqing, Yunxiao, ...

Abstract:
... Heavy metals are compounds which exist in many food products that we consume daily, and they show a toxic effect in certain concentrations. In this study, firstly, lead, cadmium, arsenic and mercury levels in 36 samples of infant formula were determined with ICP-MS. Then, infant formula consumption data of 268 babies within the age range of 0–24 months were acquired with 24 h dietary recall method ...
... Toxic metals were identified from soil and different edible and non edible parts of Allium cepa and Daucus Carota. Results showed that there is significant metal movement from soil to vegetables. Different vegetables have different mechanism of metal sorption and uptake. Levels of heavy metals in soil were in the order of Zn>Cu>Ni>Sb>Co>Mn>As>Cd>Pb>Cr before the cultivation of vegetables i.e. Alli ...
... A three-step bipolar membrane electrodialysis (BMED) system was used to remove arsenic and cation metals from copper slag (CS) generated during the copper ore hydrometallurgical process. The desorption kinetics results show that pH significantly influences metal desorption from CS. The Elovich model can be used to describe metal desorption. A high current density increased the metal desorption fro ...

Abstract:
... The burden of disease attributable to exposure to heavy metals via drinking water in Iran (2019) was assessed at the national and regional levels. The non-carcinogenic risk, carcinogenic risk, and attributable burden of disease of heavy metals in drinking water were estimated in terms of hazard quotient (HQ), incremental lifetime cancer risk (ILCR), and disability-adjusted life year (DALY), respec ...

Abstract:
... In this study, 214 surface sediment samples were collected from the offshore area of the Dongying coast and were analysed for heavy metals; particularly, their concentrations and pollution status were evaluated. The copper (Cu) and chromium (Cr) distributions were similar, their concentrations were the highest in the northeast areas and the Xiaoqing River estuary, where dominated by fine-grained s ...
... Presence of heavy metals in herbal raw materials exceeding the safety limit have potential security risks and has proven adverse effects and its prolonged consumption may causes serious health problems. The present study was carried out to quantify the heavy metals, content in some of the herbal raw materials traded in Indian market. A total 183 samples belongings to 74 different herbal raw materi ...

Abstract:
... Heavy metal contamination in cultivated land is turning out to be a major problem these days. This paper presents the experimental results of the variation of heavy metal concentration in the cultivated land before and after planting different crops and accumulation of heavy metal concentration in the crops. Six crops including corn, potato, broad beans, oats, beans and soybeans were planted in 13 ...
... The association between prenatal exposure to the metal mixture and allergic diseases is poorly understood. We aimed to explore the individual effect and the combined effect of prenatal exposure to vanadium (V), chromium (Cr), nickel (Ni), arsenic (As), cadmium (Cd), thallium (Tl), and lead (Pb) on early childhood allergic diseases based on a birth cohort study that included 628 mother-infant pairs ...
... This study aimed to assess the tissue content of essential and toxic metals including lead (Pb), cadmium (Cd), arsenic (As), silver (Ag), aluminum (Al), chromium (Cr), copper (Cu), iron (Fe), selenium (Se), and zinc (Zn) in the breast cancerous tissues compared to the non-cancerous tissue. The biopsy specimens of 63 breast cancers along with 63 adjacent healthy tissues in Kurdistan Province, Iran, ...

Abstract:
... Drinking water is considered to be an important exposure pathway for humans to ingest trace elements; human urine samples are widely accepted as biometric substrates that can reflect human exposure to trace elements. The current study aimed at investigating the concentrations of trace elements including selenium (Se), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel ( ...
... Trace elements have various physiochemical functions in humans and are associated with the occurrence of preterm birth (PB). However, their mixed effects on PB risk have rarely been studied. We aimed to investigate the associations between hair levels of trace elements and PB risk among pregnant women. A nested case-control study with a prospective cohort was conducted in Beijing City, China. We i ...
... Cadmium (Cd) and Arsenic (As) in rice grains are a primary exposure source for human beings. However, the simultaneous stabilization of Cd and As in soil becomes difficult due to the opposite properties of those. In this study, we investigated the simultaneous effects of biochar-supported nanoscale zero-valent iron (nZVI-BC) and water management on the decrease of Cd and As bioaccumulation in rice ...

... People living and working in artisanal and small-scale gold mining (ASGM) areas are frequently exposed to elemental mercury (Hg), which is used for gold extraction. However, additional exposure to other toxic metals such as arsenic (As), cadmium (Cd) and lead (Pb) may result from mining-related activities and could be ingested via dust, water or food. In these areas, only limited biomonitoring dat ...
... The 32-mile Detroit River and surrounding tributaries have been designated as a Great Lakes Area of Concern due to pollution from decades of municipal and industrial discharges, sewer overflows and urban development. The Agency for Toxic Substances and Disease Registry and the Michigan Department of Health and Human Services conducted a biomonitoring study to assess exposures to persistent toxic s ...
... Cadmium (Cd) and arsenic (As), two common heavy metals that are toxic to living bodies, are often commonly coadsorbed onto minerals in the soil environment and influenced by many surrounding factors. Among them, pH is the critical factor in determining the As(V)–Cd(II) interaction during coadsorption processes; hence, this study aimed to elucidate the regulatory mechanisms in determining the As(V) ...
... Silver nanoparticles (AgNPs) and heavy metals are considered to coexist in the environment. Increasing evidence shows that AgNPs can interact with heavy metals; however, the impact of distinct exposure conditions on their combined toxicity is still largely unknown. Here, we investigated the co-effects of AgNPs and heavy metals, including arsenic (As), cadmium (Cd), and nickel (Ni), in target cell ...
... Heavy metals play an important role in inducing fine particulate matter (PM₂.₅) related cardiovascular disease (CVD). However, most of the past researches concerned the associations between CVD mortality and the PM₂.₅ mass, which may not reveal the CVD mortality risk contributed by heavy metals in PM₂.₅. This study explored the correlations between individual heavy metals in PM₂.₅ and CVD mortalit ...
... There is increasing interest in using autonomous sensor technology to monitor aquatic ecosystems in real time and in employing such monitoring data to perform better ecological risk assessments. At seven locations in McClean Lake in northern Saskatchewan (Canada) that received diluted uranium milling effluent, we deployed sensor units to track effluent distribution and help predict potential biolo ...
