High Purity Standards New Brochures
High Purity Standards have recently added parts 2 new products, ICP-MS-HM and QCS-23. Both are ICP-MS and ICP multi solutions respectively . ICP-MS-HM is a mix comprised of the “big 4” heavy metals (As, Hg, Cd, Pb), designed for environmental labs with ICP-MS instrumentation in mind as well as customers in the cannabis and pharmaceutical industry. QCS-23 is a 23 element mix at 1000 ppm that adds to our existing line of quality control standards for ICP.

COMMONLY USED PESTICIDES EXPLAINED: 1,3-DICHLOROPROPENE
Dichloropropene is an abundant pesticide used on crops across the United States to control pests. 1,3-Dichloropropene, is sold under diverse trade names, it is an organochlorine compound. It is colorless liquid with a sweet smell. It dissolves in water and evaporates easily. It is used mainly in farming as a pesticide, specifically as a preplant fumigant and nematicide. It is widely used in the US and other countries, but is in the process of being phased out in the European Union. From peanuts to potatoes, dichloropropene is used as a fumigant which both deteriorates in the soil and disperses into the air before seeds can be planted. Recently, dichloropropene has been featured in the news regarding the EPA’s updated risk assessment. Read more to learn about this commonly used pesticide.
Evidence for the carcinogenicity of 1,3-dichloropropene in humans is inadequate, but results from several cancer bioassays provide adequate evidence of carcinogenicity in animals. In the US, the Department of Health and Human Services (DHHS) has determined that 1,3-dichloropropene may reasonably be anticipated to be a carcinogen. The International Agency for Research on Cancer (IARC) has determined that 1,3-dichloropropene is possibly carcinogenic to humans. The EPA has classified 1,3-dichloropropene as a probable human carcinogen.
1,3-Dichloropropene is used in agriculture as a pesticide. In fact, dichloropropene is one of California’s most-used non-organic pesticides when compared to others in pounds applied and the eighth most-used pesticide in the US per year, with 20-25 million pounds applied annually.
Specifically, dichloropropene which is a liquid but is used as a soil fumigant in its gaseous (volatilized) form. Soil fumigants are pesticide formulations that are incorporated into soil as gases. Fumigant gas molecules move through the pores of the soil and kill pests. Once the pesticide decomposes in the soil or diffuses into the atmosphere, seeds can be planted. Dichloropropene is a soil fumigant that can control pests through its nematicidal, fungicidal, insecticidal, and herbicidal properties, meaning it can kill nematodes, fungus, insects, and weeds. Therefore, dichloropropene is used on a variety of crops to improve yields.
Dichloropropene is a widely used pesticide because of its ability to be used on various popular agricultural crops. These crops include deciduous fruit and nuts, field crops like grains, bush and vine planting sites, citrus fruit, strawberries, sugar beets, potatoes, vegetables, tobacco, cotton, flowers, and ornamental trees. Dichloropropene is actually the main pesticide used for tobacco, potatoes, sugar beets, cotton, peanuts, sweet potatoes, onions and carrots which are crops that have such high pest pressure, that not applying pesticides is not possible for sufficient yields.
Recently, Dichloropropene has been featured in the media due to shifting regulations from the EPA and backlash from attorneys general and environmental groups. The EPA recently submitted a new risk assessment for dichloropropene that has downgraded its cancer risk from “likely to be a carcinogen” to “suggestive evidence of carcinogenic potential”. Eight attorneys general have openly criticized the EPA for minimizing dicholoropropene’s cancer risk as farm workers and certain communities continue to be exposed disproportionately to the fumigant. Meanwhile, the 2019 Agricultural Fumigants Market size report was released, and experts predict the fumigant market to grow. The attorneys general have asked the EPA to revise the human health risk assessment and the EPA has responded by saying it would review the comments. No matter the risks of dichloropropene, it does not change the current agricultural circumstances that require it to grow several crops in the US.

The effects of the novel coronavirus pandemic that has swept the globe during the early months of 2020 are wide-ranging and cataclysmic. First and foremost among them is the devastating tragedy of 170,000-plus deaths worldwide (as of April 15, 2020, per data from The Washington Post), but the economic impact is also undeniably, massively adverse.
While much of the world's population voluntarily stays home to help "flatten the curve" of infection, those considered "essential workers" are still out, and they risk contracting the virus's signature respiratory disease, COVID-19, every second they spend outdoors or in public, non-sterilized indoor settings.
COVID-19 is not fatal by default, but the risk of death or serious, long-lasting illness is much higher among certain groups of people: the elderly, those with compromised immune systems and individuals already prone to respiratory illnesses – throat-cancer patients, asthmatics and so on, according to the Centers for Disease Control and Prevention. Some experts have determined that regular exposure to certain chemical compounds may also increase one's chances of contracting the pandemic's disease.
Roots of the issue
The foundations for this chemical vulnerability are, unlike the disease whose odds they exacerbate, not novel, because they date back decades – nearly half a century, in fact.
Frederick S. vom Saal, Ph.D., a professor emeritus at the University of Missouri-Columbia, and Dr. Aly Cohen, founder and medical director at Integrative Rheumatology Associates, wrote a guest column for Environmental Health News in which they identified endocrine-disrupting chemicals as particularly dangerous in light of COVID-19. These substances, which include bisphenol A (better known as BPA) and the even more infamous chemicals in the perfluoroalkyl and polyfluoroalkyl families, are still found fairly easily in most people's daily lives.
Some exposure situations where EDCs can be found – working in factory settings, for example, are not as urgent at the moment, but others such as touching the packaging of many processed foods – are all but unavoidable.
EDC damage leading to increased COVID-19 risk
All of the chemicals under the EDC umbrella – in conditions of regular, consistent exposure – can compromise the function major endocrine glands within the brain, including the pituitary, pineal, thyroid and hypothalamus. The Endocrine Society noted that damage to these areas can impair the natural course of basic human growth in many ways: slowing metabolic development, weakening the development of immune responsiveness, throwing off proper calcium balance and putting reproductive abilities in grave danger, among others.
Damage to the immune system represents the most obvious route by which EDC exposure could increase one's likelihood of contracting COVID-19. That said, most of the other adverse effects scientists have linked to EDCs also contribute to making the body weaker in ways that, at the very least, don't contribute to better health.
In the interest of determining their local risk level and contributing in a notable way to flattening the curve of COVID-19, any businesses that have used PFAS chemicals and other BPAs in their manufacturing processes would be wise to commission an environmental impact assessment to figure out if their material usage has caused harm.
