“…Although the total mass of Ag used in this manner is relatively small in comparison with other industrial and commercial uses, many nanosilver applications (e.g. in personal care products and textiles) are dispersive in nature (Donner, 2010), and wastewater is the principal receiving pathway. This contrasts with other major uses where resource capture and recovery are used to both economic and environmental advantage.…”

Increasing commercial use of nanosilver has focussed attention on the fate of silver (Ag) in the wastewater release pathway. This paper reports the speciation and lability of Ag in archived, stockpiled, and contemporary biosolids from the UK, USA and Australia, and indicates that biosolids Ag concentrations have decreased significantly over recent decades. XANES revealed the importance of reduced-sulfur binding environments for Ag speciation in materials ranging from freshly produced sludge to biosolids weathered under ambient environmental conditions for more than 50 years. Isotopic dilution with (110 m)Ag showed that Ag was predominantly non-labile in both fresh and aged biosolids (13.7% mean lability), with E-values ranging from 0.3 to 60 mg/kg and 5 mM CaNO3 extractable Ag from 1.2 to 609 μg/kg (0.002-3.4% of the total Ag). This study indicates that at the time of soil application, biosolids Ag will be predominantly Ag-sulfides and characterised by low isotopic lability.

“…Most of the studies relate to male meiosis, so the sensitivity of the ovule is largely unknown. Hundreds of xenobiotic compounds have been assessed, including those tested by the Tradescantia Trad-MCN assay, but this represents a small fraction of the 10,000s of compounds present in the environment ( Donner et al, 2010 ; European Psychiatric Association [EPA], 2018).…”

“…Atmospheric and terrestrial pollutants, and xenobiotic compounds (defined as any non-biological compounds that have a detrimental effect on the organism) are prevalent in the environment. The actual number of such compounds is difficult to ascertain accurately, but the United States Environmental Protection Agency currently lists over 85,000 substances on their Toxic Substances Control Act Chemical Substance Inventory ( Donner et al, 2010 ; European Psychiatric Association [EPA], 2018 1 ). The genotoxicity of such compounds on plants has been assayed using a variety of methods and a range of plants species including Tradescantia paludosa , Allium cepa , and Vicia faba ( Kristen, 1997 ).…”

Anthropogenic Impacts on Meiosis in Plants

As the human population grows and continues to encroach on the natural environment, organisms that form part of such ecosystems are becoming increasingly exposed to exogenous anthropogenic factors capable of changing their meiotic landscape. Meiotic recombination generates much of the genetic variation in sexually reproducing species and is known to be a highly conserved pathway. Environmental stresses, such as variations in temperature, have long been known to change the pattern of recombination in both model and crop plants, but there are other factors capable of causing genome damage, infertility and meiotic abnormalities. Our agrarian expansion and our increasing usage of agrochemicals unintentionally affect plants via groundwater contamination or spray drift; our industrial developments release heavy metals into the environment; pathogens are spread by climate change and a globally mobile population; imperfect waste treatment plants are unable to remove chemical and pharmaceutical residues from sewage leading to the release of xenobiotics, all with potentially deleterious meiotic effects. In this review, we discuss the major classes of exogenous anthropogenic factors known to affect meiosis in plants, namely environmental stresses, agricultural inputs, heavy metals, pharmaceuticals and pathogens. The possible evolutionary fate of plants thrust into their new anthropogenically imposed environments are also considered.

“…Alcohol is a Sirt1 inhibitor [144][145][146][147] and its consumption may promote hepatic dysfunction such as alcoholic fatty liver with the ill affects on hepatic xenobiotic metabolism that are now released to various organs in the periphery and brain. Activators of hepatic Sirt 1 are important to prevent chronic diseases with the maintenance of liver nuclear receptors and regulation of nutrient and xenobiotic metabolism [61,62] Foods that contain toxic xenobiotics [148] induce genotoxic stress with chromatin modifications that leads to hepatic DNA damage and NAFLD that threaten the survival of various obese and diabetic individuals [148,149].…”
