TL;DR: This review focuses on and describes heavy metal contamination in soil-food crop subsystems with respect to human health risks, and explores the possible geographical pathways of heavy metals in such subsystems.

TL;DR: The concept of the Water-Food-Energy nexus must be expanded, forming the Water/Soil/Energy nexus, because ongoing soil degradation is decreasing the long-term ability of soils to provide humans with services, including future food production, and is causing environmental harm.

TL;DR: The environmental and health hazards associated with a widespread distribution of micro-pollutants, pesticides, pharmaceuticals, hormones, and industrially-related synthetic dyes and dyes-containing hazardous pollutants, etc. in the water bodies are discussed.

TL;DR: A novel sorbent for the removal of potentially toxic elements, inherent cations, and hetero-chloride from hydraulic fracturing wastewater (FWW) by elucidating the removal mechanisms of different contaminants is demonstrated.

TL;DR: An ensemble model that integrated multiple machine learning algorithms and predictor variables to estimate daily PM2.5 at a resolution of 1’km × 1 km across the contiguous United States allows epidemiologists to accurately estimate the adverse health effect of PM 2.5.

TL;DR: The present review focuses on the environmental sources of antibiotics, it's possible degradation mechanisms, health effects, and bacterial antibiotics resistance mechanisms, and the antibiotic degradation and elimination from the environment and its health benefits.

TL;DR: The present paper is focused on the remediation of noxious wastes from wastewater using graphene based materials as adsorbents, and it contains all the details on materials - i.e., from their synthesis to application in the field of wastewater treatment (removal of hazardous contaminants of different chemical nature - heavy and rare-earth metal ions, and organic compounds - from wastewater effluents).

TL;DR: Immobilization is highlighted as a promising approach to improve enzyme catalytic performance and stabilization, as well as, to protect the three-dimensional structure of the enzyme against the undesirable consequences of harsh reaction environment.

TL;DR: Particulate plastics made of synthetic polymers, their origin, and characteristics are described with emphasis on how particulate plastics and associated toxic trace elements contaminate terrestrial and aquatic ecosystems.

TL;DR: This review focuses on current technologies for the production of polyhydroxyalkanoates (PHA) from food waste, with particular attention paid to fermentation technologies based on pure and mixed cultures.

TL;DR: Arsenic was found to be the primary contributor to total risk, accounting of 57.4% of HI in all three- person groupings, and the presence of V, a less-expected element, among those of major risk contribution, reveals the necessity of monitoring areas at large scale.

TL;DR: Findings provide support that street view green and blue spaces are protective against depression for the elderly in China, yet longitudinal confirmation to infer causality is necessary.

TL;DR: This first analysis of the diversity, abundance, and co-occurrence of ARGs and MRGs, and their relationships within the microbial community, using metagenomic data of plastic particles observed in the North Pacific Gyre obtained from the National Centre for Biotechnology Information Sequence Read Archive database suggests the co-effects of selection for antibiotic or metal resistance are important factors influencing the resistome of the microbiota on the plastic particles.

TL;DR: Indoor dust is a non-negligible source of human exposure to MPs, accounting for a geomean daily intake of 17,300 ng/kg-bw of PET MPs in children, and polyester was identified as an important component in MPs from dust.

TL;DR: FA can be leveraged to substantially enhance the biodegradability of secondary sludge, which would further improve biological nutrient removal and enhance renewable energy production.

TL;DR: This review aimed at collecting TE regulation limits in soils from major countries and organizations around the globe, and critiquing them by assessing potential human health risks in the case of soils attaining the maximum allowable values by calculating human health risk indices.

TL;DR: Factors affecting Hg release from soil to the atmosphere are reviewed, including how rainfall events drive gaseous elemental mercury flux from soils of low Hg content, and how ambient conditions such as atmospheric O3 concentration play a significant role.

TL;DR: The health risk assessment indicated that ingestion is the most important pathway of exposure to metal pollution in street dust for both children and adults, followed by dermal contact and inhalation, and the health risks for children were higher than those for adults.

TL;DR: The impacts of poultry and cattle manure application on the patterns of resistome in soil and lettuce microbiome including rhizosphere, root endosphere, leaf endosphere and phyllosphere are explored, to identify the potential transmission routes of ARGs in the soil-plant system.

TL;DR: Predictions were equally good in capturing annual and daily PM variability, therefore they can be used as reliable exposure estimates for investigating long-term and short-term health effects.

TL;DR: Significant greater stability and enhanced nitrogen removal efficiency have been demonstrated in the novel integrations of PD and anammox process, indicating a broad perspective in dealing with the mainstream municipal sewage, ammonia-rich streams, and industrial NO3--N contained wastewater.

TL;DR: This study proposes a low-carbon, cement-free, clay-based approach for simultaneous S/S of As and Pb in the contaminated soil, and elucidates the chemical interactions between alkali-activated clay binders and potentially toxic elements.

TL;DR: Assessment of plausible sources of heavy metals at children's playgrounds in a representative metropolitan environment in Beijing suggests that heavy metals in playground equipment dust may derive mainly from atmospheric deposition of air pollution of both natural and anthropogenic origin.

TL;DR: Three statistical models were applied to assess the association between the exposure to a mixture of seven xenobiotics and obesity and MCOP, BPA, and BPS were identified as the most important factors associated with obesity.

TL;DR: It is concluded that urban vegetation can facilitate broad health benefits, but there is little empirical evidence linking these benefits to air pollution reduction by urban vegetation, and appreciable efforts are needed to establish the underlying policies, design and engineering guidelines governing its deployment.

TL;DR: It is suggested that polar PAHs could have serious toxicological effects on human health and should be considered during risk assessment of PAH-contaminated sites and critical knowledge gaps and future research requirements are discussed.

TL;DR: A new machine learning (ML) model with high-dimensional expansion (HD-expansion) of numerous predictors (including AOD and other satellite covariates, meteorological variables and CTM simulations) is developed to predict daily PM2.5 concentrations during 2000-2016 across China and estimate long-term trends in PM 2.5 for the period.

TL;DR: The background information and developments from pure TiO2 to chemically modified TiO1-based materials as photocatalysts were discussed in detail, which covered their basic properties and their role in the air pollutant removal.

TL;DR: An optimized method that considers the frequency of concentrations above predicted no effects levels was developed on the basis of the traditional method, and it was then used to identify and screen candidate priority pollutants in European surface waters and proved the feasibility and advantages of the optimized method.

TL;DR: Using O3 exposure-response functions, the costs of O3-induced losses in rice, wheat, forests and forest production, and SOMO35-based morbidity for respiratory diseases and non-accidental mortality are evaluated, representing 7% of the China Gross Domestic Product in 2015.
