As concern about the impact of conventional, petroleum-based plastics grows, bioplastics (BP) and degradable plastics (DPs) have emerged as potential sustainable alternatives.&nbsp; But the fate of BPs and DPs in the environment it remains unclear and some may breakdown into nano...

Silver nanoparticles (AgNPs) are the most widely used engineered nanomaterials in consumer products, primarily due to their antimicrobial properties. This widespread usage has resulted in concerns regarding potential adverse environmental impacts and increased probability of huma...

This presentation covers current methods used for extraction of microplastics, future potential instrumentation, an overview of interlaboratory comparisons, EPA's method development for micro and nanoplastics and future directions for the field.&nbsp;

Informal presentation for the Database Interest Group on creating a consortium of federal agencies to consolodate and integrate data on nanomaterial and nanoEHS data.Informal presentation for the Database Interest Group on creating a consortium of federal agencies to consolodate ...

Micronized Cu (&micro;-Cu) is used as a wood preservative, replacing toxic chromated copper arsenate (CCA). Micronized Cu is malachite [Cu2CO3(OH)2] that has been milled to micron/submicron particles, many with diameters less than 100 nm, and then mixed with quat or azole biocide...

Microplastics (MPs) and nanoplastics (NPs) have gained much attention in recent times because of their ubiquitous presence, which is widely acknowledged as a threat to the environment. MPs can be of less than 5 mm size, while NPs are less than 100 nm, and all of these can be dete...

Background: The difference between an individual’s chronological and DNA methylation predicted age (DNAmAge), termed DNAmAge acceleration (DNAmAA), can capture life-long environmental exposures and age-related physiological changes reflected in methylation status. Several studies...

Microbial electrolysis cells (MECs) can produce hydrogen gas from organic compounds in an energy-efficient way by taking advantage of the potential generated by microorganisms. Human urine has been successfully used as an electrolyte and organic substrate in bioelectrochemical sy...

Magnetic graphene catalysts were prepared for the removal of antibiotics (sulfamethoxazole, norfloxacin, tetracycline and flumequine) in wastewater. Different proportions of magnetite-graphene from 1:0 to 0:1 were considered to study the catalytic activation of inorganic peroxide...

The presentation outlines the basics of nanotechnology from creation in a lab to incorporation into consumer products. Nanotechnology is based on the words &quot;nano&quot;, meaning one billionth in size, and technology. There are many types of nanotechnology including nanowires,...

The use and production of engineered nanomaterials have grown exponentially over the past few decades due to their unique properties and versatility.&nbsp;&nbsp;As a result of widespread industrial applications, nanomaterials have evolved into their own unique class of emerging c...

As the market for “nano-enabled” products (NEPs) continues to expand in commercial and industrial applications, there is a critical need to understand conditions that promote release of nanomaterials and their degradation products from NEPs. Moreover, these studies must aim to qu...

This 20 minute presentation covers research under SSWR 1.4 Microplastics research. It describes method development for small micro- and nano- sized microplastics, past, present and future RARE projects associated with microplastics and ORD innovation projects associated with micr...

The supply of safe drinking and clean water is becoming increasingly challenging proposition throughout the world. The deployment of environmentally sustainable nanomaterials with unique advantages namely high efficiency and selectivity, earth-abundance, recyclability, low-cost o...

Micro- and nano-scale plastic particles in the environment result from their direct release and degradation of larger plastic debris. Relative to macro-sized plastics, these small particles are of special concern due to their potential impact on marine, freshwater, and terrestria...

In recent years, an increasing number of polymeric composites incorporating engineered nanomaterials (ENMs) have reached the market. Such nano-enabled products (NEPs) present enhanced performance through improved mechanical, thermal, UV protection, electrical, and gas barrier pro...

Achieving sustainable agricultural productivity while securing food safety to nourishing a rapidly growing world population is one of the direst challenges of this century. Addressing this challenge requires technologically-sound and evidence-driven technologies to sustainably up...

Plastic particles are now found ubiquitously in the environment, and as the abundance of plastic increases in marine systems, the magnitude of adverse biological and ecological effects of plastics of various size classes (macro-, micro-, nano-) need to be evaluated for potential ...

The use of phosphates in the drinking water industry is well known. Orthophosphate is used to reduce lead levels at the consumer’s tap by forming relatively insoluble divalent lead orthophosphate compounds on the surface of the lead source (e.g., lead service line, brass fixture...

Following substantial pH reduction in their drinking water over a span of more than 20 years, the city of Newark, New Jersey has struggled with elevated lead (Pb) release from Pb service lines and domestic plumbing in the zone fed by the Pequonnock water treatment plant. In respo...

This review focuses on the simulation of groundwater flow and solute transport through karst/fractured rock aquifers through the use of laboratory scale models. It consists of a collection of different size and types of laboratory scale models. The previously developed laboratory...

As the abundance of plastic increases in marine systems, the adverse biological and ecological effects of plastics of various size classes (macro, micro, nano) need to be evaluated to address potential risks. Nanoplastic particles (NPs) are of growing concern and enter marine sys...

Biosensors are finding new places in science, and the growth of this technology will lead to dramatic improvements in the ability to detect microorganisms in recreational and source waters for the protection of public health. Much of the improvement in biosensors has followed de...
