TL;DR: Detailed information and review on the adsorption of noxious heavy metal ions from wastewater effluents using various adsorbents - i.e., conventional (activated carbons, zeolites, clays, biosorbents, and industrial by-products) and nanostructured (fullerenes, carbon nanotubes, graphenes) is presented.

TL;DR: Adsorption is a promising method worldwide for EC removal since it is low initial cost for implementation, highly-efficient and has simple operating design.

TL;DR: Generally, ACC deaminase and IAA-producing bacteria can be a good option for optimal crop production and production of bio-fertilizers in the future due to having multiple potentials in alleviating stresses of salinity, drought, nutrient imbalance, and heavy metals toxicity in plants.

TL;DR: This review focuses on the speciation of lead in soil, its mobility, toxicity, uptake and detoxification mechanisms in plants and bacteria and bioremediation strategies for remediation of lead contaminated repositories.

TL;DR: This review provides information about the mechanisms possessed by heavy metal resistant-PGPRs that ameliorate heavy metal stress to plants and decrease the accumulation of these metals in plant, and gives some perspectives for research on these bacteria in agriculture in the future.

TL;DR: The use of Si (mostly as industrial slags and rice straw) is predicted to become a sustainable strategy and an emerging trend in agriculture to enhance crop growth and alleviate abiotic and biotic stresses in the not too distant future.

TL;DR: Based on findings from health risk assessment this study, the highest fluoride exposure for different regions of Poldasht city was observed in young consumers, children and teenager's groups, and most of the rural residents suffered from fluoride contaminated drinking water.

TL;DR: This multi-drug and multi-metal resistant bacterium can be used as a potential agent for the effective bioremediation of metal contaminated sites.

TL;DR: The pineapple leaves are an efficient precursor for preparation of ACFs, which were successful applied as adsorbent material for removal of caffeine from the aqueous solutions and revealed that adsorption process is spontaneous, exothermic and occurs preferably via physisorption.

TL;DR: It was concluded that straw could be positively effective on the improvement of the soil quality and the grain production, but it appeared that the straw return had several neglect negative effects, implying that further research and assessment on the returned straw are required before its large-scale promotion in China.

TL;DR: Results indicate that BC could be used as an amendment in metal contaminated soil for improving wheat growth and reducing Cd concentrations under semiarid conditions.

TL;DR: This review sums up the potential role of EBL in ameliorating heavy metals and pesticide toxicity in plants extensively and future needs of research about the application of 24-epibrassinolide have also been discussed.

TL;DR: The fixed-bed adsorption of pharmaceuticals on various adsorbents was reviewed and the Thomas and Yoon-Nelson more effectively predicted the breakthrough data for the studied pollutants.

TL;DR: The introduction of Sb chemistry, distribution and health threats are presented in this review, which is essential to the removal techniques, and the recent and common techniques, including adsorption, coagulation/flocculation, membrane separation, electrochemical methods, ion exchange and extraction are provided.

TL;DR: Revealing transcriptional and posttranscriptional regulation by several genes and microRNAs related to AS after xenobiotic exposure in fish will help better understanding the processes of detoxification of xenobiotics and resistance to stress, and can also provide valuable information for estimating risk assessment of environmental pollution.

TL;DR: The carcinogenic risks values for Ni and Cr were higher than the safe value, suggesting that all receptors (especially wheat) in Kermanshah province might have significant and acceptable potential health risk because of exposure toNi and Cr.

TL;DR: The muscle and carapace/exoskeleton of shrimp, lobster and crabs were analysed and contained various concentrations of Pb, Hg, As, Cr, Cd, Fe, Cu, Zn and Mn; crabs showed higher mean heavy metal concentrations than shrimp and lobster.

TL;DR: It can be concluded that BPP can be used as an effective, low cost, and eco-friendly adsorbent for CR removal than RB5 from aqueous solution.

TL;DR: Overall, the BC+CH treatment at HR was the most effective treatment for in situ immobilization of heavy metals in SPHIW and further irrigated with the same WW, compared to rest of the treatments.

TL;DR: It is suggested that Si is beneficial in remarkably affecting physiological phenomena and improving wheat growth under abiotic stress in wheat.

TL;DR: Assessment of environmentally relevant concentrations of Se toxicity in Mozambique tilapia, Oreochromis mossambicus showed that Se accumulation was observed in the gill, liver and brain tissues of fish exposed to different concentrations and accumulation varied upon different tissues.

TL;DR: The results showed that the growth of alfalfa was significantly inhibited, and an impact that was most pronounced in seedling biomass and chlorophyll content, while malondialdehyde content continually increased in metal-contaminated soil.

TL;DR: The results of this work have implications for public health near 'hot spots' such as IKBT where large populations are exposed to carcinogenic emissions.

TL;DR: Investigating the partition characteristics of phenanthrene (Phe) in three mass-produced plastic particles, including polyethylene (PE), polystyrene (PS) and polyvinylchloride (PVC) and one natural sediment, as a comparison found microplastics exhibited higher capacities for Phe, while natural sediment exhibited the largest decline.

TL;DR: The present paper summarizes the findings from the workshop: "Ecofriendly Nanotechnology: state of the art, future perspectives and ecotoxicological evaluation of nanoremediation applied to contaminated sediments and soils" convened during the Biannual ECOtoxicology Meeting 2016.

TL;DR: The aim of this literature review was to summarise the knowledge of the behaviour, and toxicity on marine and freshwater organisms, of phenols as well as to try to select a series of sensitive biomarkers suitable for ecotoxicological assessment and environmental monitoring in aquatic environments.

TL;DR: The results indicated that the concentrations of heavy metals in the freshwater fish in central and eastern North China were relatively low, and did not cause considerable human health risks.

TL;DR: The high adsorption capacity of MAHC for MB suggests that hydrothermal carbonization in acidic medium followed by alkaline treatment has the potential application to produce efficient MB adsorbents used in wastewater treatment.

TL;DR: An analysis of the Geoaccumulation Index (Igeo), Contamination Index (Pi), RI, CR and HI of heavy metals identified universal ecosystem risks and both carcinogenic and noncarcinogenic health risks in most sites.

TL;DR: This magnetic biochar derived from Enteromorpha prolifera and magnetically modified has the potential to serve as a highly efficient adsorbent for water pollution control.
