Why are chemicals more problematic than most hazards?

November 28, 2019 | 78 views

Chemical suit fabric cannot be breathable; it must be an effective barrier to a whole range of nasty substances. If the fabric allows air to permeate through, it's likely to allow those nasty substances through as well. Furthermore, chemical suits cover the whole body and may be sealed to other PPE, such as gloves or mask. Any workplace may present safety managers with a several hazards to deal with: working at height, falling objects, flames, heat and, of course, hazardous chemicals. It's always useful to think about hazards in terms of whether they have an immediate effect or a long-term effect. In the case of most hazards, the effect is immediate: if you fall from the scaffolding on a building site you will notice immediately; if a brick you were holding in one hand then falls on your head shortly after you hit the ground you will notice immediately;

Organic Catalyst Boasts Big Benefits

Article | June 29, 2021

An enzyme-mimicking catalyst opens a new route to important organic molecules such as glycolic acid and amino acids from pyruvate, report researchers in Japan. Moreover, the new catalyst is cheaper, more stable, safer and more environmentally friendly than conventional metal catalysts used in industry, they note, adding that it also displays the high enantioselectivity required by the pharmaceutical industry. “On top of these advantages, our newly developed organic catalyst system also promotes reactions using pyruvate that aren’t easily achievable using metal catalysts,” says Santanu Mondal, a PhD candidate in the chemistry and chemical bioengineering unit at Okinawa Institute of Science and Technology (OIST) Graduate University, Okinawa, Japan, and lead author of a study recently published in Organic Letters. “Organic catalysts, in particular, are set to revolutionize the industry and make chemistry more sustainable,” he stresses. The researchers use an acid and an amine mixture to force the pyruvate to act as an electron donor rather than its usual role as an electron receiver (Figure 1). Effectively mimicking how enzymes work, the amine binds to the pyruvate to make an intermediate molecule. The organic acid then covers up part of the intermediate molecule while leaving another part that can donate electrons free to react to form a new product. Currently, the organic catalyst system only works when reacting pyruvate with a specific class of organic molecule called cyclic imines. So, the researchers now are looking to develop a more-universal catalyst, i.e., one that can speed up reactions between pyruvate and a broad range of organic molecules. The challenge here is to try to make the electron-donating intermediate stage of pyruvate react with other functional groups such as aldehydes and ketones. However, different catalysts create different intermediates, all with different properties. For example, the enamine intermediate created by the researchers’ new reaction only reacts with cyclic imines. Their hypothesis, currently being investigated, is that creation of other intermediates such as an enolate, if possible, would achieve a broader pyruvate reactivity. In terms of cost, the researchers note that a palladium catalyst used in similar reactions is 25 times more expensive than their organic acid — which also is made from eco-friendly quinine. In addition, they believe scale-up of the process for industrial use definitely is possible. However, the researchers caution that the current amine-to-acid-catalyst loading ratio of 1:2 probably would need to be optimized for better results at a larger scale.

Transporting biological and chemical materials - what you need to know

Article | June 6, 2022

The landscape of biological and chemical logistics has changed rapidly - as have the regulatory frameworks around it. What has not necessarily kept pace is the end-user understanding of the nature of these logistical processes, their opportunities and their constraints. Twenty years ago, the transmission of biological and chemical materials was limited to a small range of organisations: usually national and international research companies, hospitals, major university departments, police and military departments with forensic responsibilities.

Setting record straight on testing harm in chemicals

Article | June 27, 2021

The modern world is built on chemicals, be it the medicines we use, or cleaning fluids, crop protection products, or the raw materials for everything from laptops and mobile phones to clothes and furniture. Across all, we have created an entire modern society with chemicals, and, as a result, constantly stretched the size of the world population we can feed, clothe and shelter. Yet, balancing all the gains from the modern chemistry around us against any negative environmental and human impact has been a rising concern, making for ever greater focus on testing and on risk assessment.

Why chemical characterization is the best way to assess patient risk

Article | February 11, 2020

Everyone is very familiar with the phrase when buying a house: All that really matters are three things - location, location, and location. This same principle applies to extractables and leachables chemistry analysis – the three things that truly matter are identification, identification, and identification. The greatest growth in the past ten years in demonstrating the safety of medical devices and container closure systems for drugs has been using analytical chemistry to determine what chemicals can leach from the device and what the patient is exposed to during its intended use.

NGOs file suit over transparency of TSCA new chemicals programme

Chemical Watch | March 18, 2020

A coalition of NGOs has sued the US EPA over an alleged lack of transparency in the TSCA new chemicals programme, which "thwart[s] the ability of the public to be informed and to provide input". According to a complaint filed by five environmental nonprofits in federal court today, the EPA has operated its TSCA premanufacture review process in a "black box, denying the public information to which they are legally entitled". Having access to timely information, they contend, is necessary to ensure the members they represent "are able to provide input on the potential risks of new chemicals and the need for protections from those risks prior to completion of EPA’s reviews." And they therefore have asked the court to ensure that the EPA complies with TSCA’s disclosure provisions, including by requiring that it:

ACC to Trump, governors: Keep chemical industry going during coronavirus crisis

S&P Global | March 18, 2020

The US chemical industry's trade group told President Donald Trump and state governors this week that its sector must maintain operations as the coronavirus outbreak spreads to ensure supply of chemicals needed for disinfectants, plastics for food preservation and medical equipment, and staples like diapers and soap. "The role of chemistry is particularly important today, as chemicals enable countless products that will be needed to support good hygiene and treat those who are infected with the coronavirus in the weeks and months ahead," American Chemistry Council President and CEO Chris Jahn said in a letter to Trump and governors late Tuesday. Efforts to hinder the spread of coronavirus have included cancellations of major sporting events, concerts, conferences, parades, and other large gatherings, as well as closures of bars and limiting restaurants to takeout and deliveries. Companies have increasingly sent employees to work from their homes, while hospitals, grocery stores, and drug stores work to keep up with demand for care and products.

How small chemical company leaders are dealing with the coronavirus

C&EN | March 17, 2020

As measures to contain the coronavirus—SARS-CoV-2—sweep across the US, the heads of privately owned chemical and instrument companies find themselves in uncharted territory trying to keep their companies going and their employees safe. C&EN reached out to CEOs of several such firms to learn what they are doing to keep business moving forward. We heard stories about setbacks, as expected supplies didn’t come through, but also small triumphs, as needed safety equipment was finally found. Overall, these leaders are keeping a close eye on supplies while planning for the real possibility that orders will drop in the coming months. Keeping staff healthy and maintaining continuity in customer service are the top priorities at Boron Specialties. “We are a pretty small facility, seven people &on-site&, so as best as we can we’re isolating,” CEO and founder Beth Bosley says.
