TL;DR: It is highlighted that both adults and children consuming food crops grown in wastewater-irrigated soils ingest significant amount of the metals studied, however, health risk index values of less than 1 indicate a relative absence of health risks associated with the ingestion of contaminated vegetables.

TL;DR: The model-free affected-pedigree member method was used during initial screening with chromosome 6p, 8q, and 1p microsatellites, and only individuals with absence seizures and/or electroencephalogram 3-4-Hz spike- and multispike-slow wave complexes were considered to be affected.
Abstract: Childhood absence epilepsy (CAE), a common form of idiopathic generalized epilepsy, accounts for 5%-15% of childhood epilepsies To map the chromosomal locus of persisting CAE, we studied the clinical and electroencephalographic traits of 78 members of a five-generation family from Bombay, India The model-free affected-pedigree member method was used during initial screening with chromosome 6p, 8q, and 1p microsatellites, and only individuals with absence seizures and/or electroencephalogram 3-4-Hz spike- and multispike-slow wave complexes were considered to be affected Significant P values of 00000-02 for several markers on 8q were obtained Two-point linkage analysis, assuming autosomal dominant inheritance with 50% penetrance, yielded a maximum LOD score (Zmax) of 36 for D8S502 No other locus in the genome achieved a significant Zmax For five smaller multiplex families, summed Zmax was 24 for D8S537 and 17 for D8S1761 Haplotypes composed of the same 8q24 microsatellites segregated with affected members of the large family from India and with all five smaller families Recombinations positioned the CAE gene in a 32-cM interval

TL;DR: It is confirmed that the sorption of PBDEs on sediment organic matter governed their spatial distribution, transport, and fate in the sediments, and risk quotients derived from concentrations ofPBDEs in sediments from the authors' study may pose high ecological risks to exposure of benthic organisms.

TL;DR: Algae played an important role in regulating the distribution of EDCs in surface waters, and relationships between UV absorbance and EDCs revealed that π-π interactions were among the dissolved organic carbon (DOC)-EDC binding mechanisms and that DOC fractions with higher degrees of aromaticity and humification possessed higher affinities towards EDCs.
25 citations
TL;DR: This study indicated that the important roles of aromatic moieties, accessibility, and microporosity in the sorption of HOCs by SOM, including the NHC fractions, dominate the overall sorption by the bulk samples.

TL;DR: The principles, advantages and disadvantages of immobilization, soil washing and phytoremediation techniques which are frequently listed among the best demonstrated available technologies for cleaning up heavy metal contaminated sites are presented.
Abstract: Scattered literature is harnessed to critically review the possible sources, chemistry, potential biohazards and best available remedial strategies for a number of heavy metals (lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel) commonly found in contaminated soils. The principles, advantages and disadvantages of immobilization, soil washing and phytoremediation techniques which are frequently listed among the best demonstrated available technologies for cleaning up heavy metal contaminated sites are presented. Remediation of heavy metal contaminated soils is necessary to reduce the associated risks, make the land resource available for agricultural production, enhance food security and scale down land tenure problems arising from changes in the land use pattern.
2,826 citations
TL;DR: The present review mainly focuses on NMOs' preparation, their physicochemical properties, adsorption characteristics and mechanism, as well as their application in heavy metal removal.
1,828 citations
TL;DR: Estimated daily intake (EDI) and THQs for Cd and Pb of rice and vegetables exceeded the FAO/WHO permissible limit and bio-accumulation factors of heavy metals were significantly higher for leafy than for non-leafy vegetable.
1,022 citations
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.
952 citations
TL;DR: A comprehensive map of both soil and water pollution threats to food safety in China is presented and integrated policies addressing soil andWater pollution for achieving food safety are suggested to provide a holistic approach.
