One of the common formulations of lithium batteries is lithium nickel manganese cobalt oxide (LiNMC) particles. Increasing utilization of LiNMC batteries would require adequate disposal and/or recycling, and yet the potential disposal of lithium batteries as waste either in or outside of landfills might lead to toxic effects to people and wildlife. However, understanding of the potential toxicity of LiNMC particles is limited. Based on previous literature investigating the mechanisms of toxicity of the constituent metals, as well as lithium cobalt oxide (LCO) nanoparticles, we hypothesized that LiNMCs would cause toxicity <i>via</i> mitochondrial impairment and oxidative stress. We further hypothesized that LiNMC toxicity would be exacerbated by knockdown of <i>frh-1</i> and <i>gas-1</i>, <i>Caenorhabditis elegans</i> orthologs of human mitochondrial disease genes frataxin and NDUFS2. Finally, we predicted that LiNMC exposure would cause developmental neurotoxicity. We tested these predictions by carrying out LiNMC exposures, and found these did not significantly impact the redox state, steady-state ATP levels, mitochondrial:nuclear DNA ratio, or oxygen consumption in worms exposed developmentally to amounts of LiNMC that caused mild growth inhibition. We discuss possible reasons for the difference between our results and previous publications, including particle size. Furthermore, while knockdown of <i>frh-1</i> and <i>gas-1</i> altered several parameters, knockdown of these genes did not increase or decrease the effects of LiNMCs. However, we did find that exposure to LiNMC caused degeneration of dopaminergic, cholinergic, glutamatergic, and GABAergic neurons, but not serotonergic neurons or glial cells. Interestingly, it appears that the developmental neurotoxicity was driven either by a particle-specific effect, or a component other than lithium, because exposure to lithium chloride at the same concentration had no effect.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

As a result of partial degradation from longer PFAS's as well as their enhanced mobility in the environment, short-chain PFAS are very prolific making them a high-target focus for PFAS removal research. Using molecular dynamics simulations of functionalized graphene oxide pores, we have shown that the selectivity and capacity of adsorption media for differing tail lengths of linear PFAS are impacted by the size of the material's nanoporosity. The relationship between PFAS transport and pore size is not monotonic and different PFAS have different critical pore diameters with a minimum in transport resistance enabling an effective mechanism for PFAS specificity. More pragmatically, we have identified critical pore diameters that impact the thermodynamics and kinetics of PFAS binding and transport. For example, selectivity towards PFBA is highest in pores of 9 Å diameter.

This review includes multiple aspects of the agents, including chemical and physical properties, lethal doses, and common surrogates.

Conventional deactivation technologies, including incineration and neutralization, are discussed along with advanced approaches, such as wet air oxidation, catalytic, and metal–organic frameworks (MOF) treatments. The review indicates that all three agents can be destroyed to nearly 100% Destruction and Removal Efficiency (DRE) with incineration, but at a high cost and with a significant energy demand, and only at secure, established facilities. Several countries have used incineration to reduce large volumes of CWA stockpiles. Other neutralization, wet air oxidation, and supercritical oxidation technologies are demonstrated at lab and pilot-scale levels to achieve 98–100% DRE depending on the operating conditions. Other relatively new technologies, such as catalytic deactivation and treatment using MOF, can achieve 70–100% efficiency but are still in the embryonic or laboratory development stage. Deactivation of CWAs with MOFs exhibit high degradation potential, reaching 100% DRE, but it may not be suitable for large volumes.

Due to the chemical stability of the carbon–fluoride bonds, they are difficult to degrade. Instead, an alternative presents itself in the form of adsorption, concentration, and then removal of PFAS from contaminated sites. Both metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have recently come under significant investigation as possible adsorption media which could be adapted for the removal of PFAS from contaminated sites. To gain greater insight into the adsorption capabilities of COFs for the removal of PFAS from waterways, we have studied the adsorption of PFAS molecules in COFs of differing pores sizes using molecular dynamics simulations. We examine the absorption of aqueous PFBA, PFOA, and PFOS into Covalent Triazine-Based Frameworks (CTF) of different pore sizes. This mechanistic adsorption data shows that a goldilocks zone occurs in pores with diameters of around 8 Å where the PFAS thread through the pores smoothly. Kinetic factors from diffusion into these nanopores favors the adsorption of short chain PFAS even though larger PFAS are thermodynamically favored. Each pore tends to initially adsorb only one PFAS, occupying the mouth of the pore, until the local COF surface is saturated and then multiple occupancy per pore can occur. Discussion on the impacts of PFAS concentration and interaction with the pores will inform design principles for enhanced selectivity and capacity for PFAS adsorbent material.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.
