Advances in nanotechnology mean that a rapidly increasing number of products are being produced using engineered nanomaterials, for example, nano-enabled thermoplastics. Many of these nano-enabled products are destined to reach their end-of-life through waste incineration or accidental fire. Now, an original study has revealed that the presence of nanofiller in thermoplastics significantly enhances both the concentration and toxicity of polycyclic aromatic hydrocarbons (PAHs) produced during thermal decomposition at the product’s end- of-life, resulting in concentrations of total PAHs and more toxic PAHs that are up to eight times higher than those found in pure (non nano-enabled) thermoplastics. This finding has significant environmental health implications.

Water pollution by toxic elements is a major economic and environmental concern, and mercury is one of the most poisonous of the elements to be released into the environment by industry. Mercury exposure can cause severe ill health. Efficient, simple and convenient methods to remove mercury from industrial and other waste streams and drinking water are essential. This study successfully trialled a new technique, using magnetised multi-walled carbon nanotubes (MWCNTs), to remove mercury from waste water.

Currently laws and regulations governing nanotechnology are fragmented and do not take account of the unique properties of nanomaterials, the effect of which on humans and the environment are not yet fully understood, argue researchers in a new study. In the study, a network of European researchers propose a new universal regulatory framework that deals specifically with nanomaterials. The framework should help policymakers, organisations and researchers evaluate the risks of any existing materials and new nanomaterials entering the market. It should also help SMEs and large companies use safer products and processes, limit the potential adverse effects of nanomaterials on workers and consumers, reduce the cost of insurance and reduce the risk of governments having to pay out money in the future due to unforeseen accidents or diseases.

Nano-sized particles of plastic can be more damaging to marine species than larger sized microplastics, a new study shows. Lab tests revealed that nanoplastics can damage cell membranes in tiny marine creatures called rotifers (Rotifera), disrupting their natural defences against toxicants. The researchers found that rotifers that had been exposed to nanoparticles of polystyrene were significantly more susceptible to the lethal effects of persistent organic pollutants (POPs).

Silver nanoparticles present in the effluent from waste-water treatment plants could have toxic effects on aquatic organisms, new research suggests. The lab-based study tested the effects of nanoparticle-containing effluent on several crustacean and algae species. The researchers observed that epibenthic crustaceans (those living in or on sediments at the bottom of water bodies) were the most sensitive; notably, a 20–45% higher death rate was observed compared with those exposed to nanoparticle-free effluent.

Researchers have measured the presence of carbon nanoparticles in the air over the Mediterranean Sea. The results revealed that higher concentrations are found in air that has moved over areas of industrial activity, and that the lowest layers of the atmosphere are likely to be responsible for transporting the nanoparticles.

Researchers have presented an extensive analysis of the role of nanomaterials in environmental remediation and monitoring. Nanomaterials can be used to clean up toxins and bacteria from natural waters, wastewaters and the air.

The chances of a child developing Autism Spectrum Disorder (ASD) are higher if the mother is exposed to high levels of fine particulate air pollution during pregnancy, a recent study suggests. This increased risk was associated specifically with exposure in the last three months of pregnancy, the researchers found.

Researchers have assessed the phyto-toxic effects of copper nanoparticles on vegetables grown within urban gardens, comparing increasing doses of these nanoparticles to simulate potential aerial deposition to extreme pollution of CuO-NP in a range of increasing exposure periods. Lettuce and cabbage absorbed high amounts of copper nanoparticles, after 15 days of exposure, which interfered with photosynthesis, respiration and also reduced growth. Under the specific exposure conditions of the study the researchers indicate that metal nanoparticles could lead to potential health risks to humans from the contamination of crops from pollution.

Applying a low voltage to polluted river sediment can boost microbes’ natural ability to degrade harmful polychlorinated biphenyl (PCB) contaminants, according to a new study. The approach could be a cost-effective, sustainable strategy to bioremediate polluted sites.

Engineering at the nanoscale brings the promise of radical technological development — clean energy, highly effective medicines and space travel. But technology at this scale also brings safety challenges. Nano-sized particles are not inherently more toxic than larger particles, but the effects are complex and vary based on particle properties as well as chemical toxicity. This Report brings together the latest science on environmental safety considerations specific to manufactured nanoscale materials, and some possible implications for policy and research.

Researchers have analysed the ability of two organic nanomaterials to remove the heavy metal chromium from water. In the laboratory, the nanomaterials successfully took up around 95% of the chromium. Further work is needed to confirm the feasibility of using these nanomaterials to purify water in real-world conditions.

Although nanomaterials are already in widespread use, their risk to the environment is not completely understood. Researchers in the US have developed a next-generation risk-assessment model to better understand nanomaterials’ environmental impact. Applied to the San Francisco Bay area, the model predicted that even soluble nanomaterials could accumulate at toxic levels.

--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the remnants of Priscilla were located
near latitude 20.0 North, longitude 104.7 West. The remnants are
moving toward the north-northwest near 10 mph (17 km/h).

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: The remnants of Priscilla are expected to produce
rainfall accumulations of 5 to 10 inches, with local amounts to 15
inches, across portions of Nayarit, Jalisco, Colima, and Michoacan
in southwestern Mexico through Tuesday night. This rainfall could
produce flash flooding and mudslides within steep terrain.

Remnants Of Priscilla Discussion Number 4
NWS National Hurricane Center Miami FL EP192019
1000 PM CDT Sun Oct 20 2019

The rugged terrain of Mexico has taken a toll on Priscilla. Surface
observations indicate that the system no longer has a closed
surface circulation, and therefore this is the last advisory
issued by the National Hurricane Center on this system.

Even though the surface circulation has dissipated, there is
still a fair amount of deep convection associated with the
remnant trough over portions of southwestern and west-central
Mexico. Since the surface trough is expected to linger for another
couple of days over southwestern Mexico, there remains a significant
threat of heavy rains and flash flooding over that region.
