Any image two hotdog dogs are shown. The top hotdog dog sitting in a bun is straight below, a bun with a curved hot dog. The text reads. How a "growth company" grows Are straight hot dogs better than curved ones? Hint: Rayonier cellulose chemistry lowers costs Answer: They're both mighty good eating. But the straight hot dog is skinless-and won't vary a jot in taste, color or texture. That's because it's shaped in special, sanitary cellulose casings. And it's the casing (stripped off after smoking) that makes straight "dogs" lower in cost, consistent in deliciousness. What's in it for you? Chemical cellulose for sausage RAYONIER IN CORPO RATED making is only a fraction of Rayonier's growth business. But this versatile raw material can actually keep many sausage meats several cents a pound cheaper on your butcher's shelf! That's because cellulose speeds production, delivers wholesome, appetizing, fresh meats. Thus, with ever better celluloses, Rayonier assures you real value in over 500 different products ranging from miracle fibers to hot dogs. In this way and others, Rayonier grows. cellulase chemistry Executive and General Sales Offices: 161 East 42nd St., New York 17, New York
The EU cracks down on ‘forever chemicals’ with new protections for drinking water. What will change?
EU-wide protections against ‘forever chemicals’ in drinking water have officially come into effect, providing member states with the “rules and tools” to protect public health.
It’s the first time levels of PFAS (per- and polyfluoroalkyl substances) are being “systematically monitored”.
The Old and New Persistent Organic Pollutants; Sources, Risks, Regulations, and Remediation by Ravi Naidu, 2025
This book provides a comprehensive coverage of new and old hazardous chemicals, their physical and chemical properties, their breakdown products, their fate in the environment, and the environmental and human risk impact.
Our understanding of persistent organic pollutants (POPs), their exposure pathways, and their impact on the environment and human health is constantly evolving and the list of new and emerging POPs is constantly changing. This book provides a comprehensive coverage of new and old hazardous chemicals, their physical and chemical properties, their breakdown products, their fate in the environment, and the environmental and human risk impact. It discusses global policies based on the United Nations’ FAO frameworks, explains the severity of contamination, and raises awareness on the assessment and remediation of contaminated sites in developed and developing countries.
Features:
• Provides a broad temporal perspective on POPs with contributions from a global team of experts.
• Covers chemistry, toxicology, remediation, regulation, and conventions related to POPs.
• Explains systematically the fate and behavior of POPs and their effect on the environment and ultimately the impact on human health.
• Brings together for the first time information on global policies on POPs.
• Includes case studies that detail assessment criteria of old and new POPs as well as remediation technologies.
This book is an excellent resource for professionals, researchers, academics, and students who work in or study environmental risk assessment and remediation.

"Recent media coverage of substances such as PFAS has increased awareness of POPs and emphasised the need for improved regulation of chemicals to protect future generations."
Chemical Environmental Pollutants and Their Effect on Health by Aikaterini Salavoura, 2025
This book focuses on the impact of environmental chemicals on human health. Its coverage includes metals contaminating the environment, persistent organic pollutants (POPs), air pollution and endocrine disruptors. Harmful consumer products, workplace exposure, cosmetics, microplastic waste are described.
Since most chemical substances are related to degenerative disorders and other communicable diseases, the proposed models of disease are analyzed, including cancer and psychiatry disorders. To provide an understanding of the mechanisms of diseases due to exposure, the book also covers basic background knowledge in genetics and epigenetic mechanisms. Oxidative stress and antioxidant mechanisms of the body are presented and how chronic inflammation and oxidative stress leads to disease. Finally, the role of a well-balanced diet and ingredients in the diet which prevent disease as well as the mechanisms of prevention are emphasized.
France's parliament on Thursday voted to limit the production and sale of some items containing polluting and health-threatening "forever chemicals" including cosmetics, most clothing and ski wax.
"Toxic 'forever chemicals' are increasingly appearing in U.S. pesticides — contaminating waterways and posing a possible threat to human health, a new study has found.
"Pesticides containing these compounds, called per- and polyfluoroalkyl substances (#PFAS), are used widely nationwide on staple foods, such as #corn, #wheat, #kale, #spinach, #apples and #strawberries, according to the study, published Wednesday in Environmental Health Perspectives.
"Known for their ability to linger in the human body and the environment, PFAS have been linked to many illnesses, such as thyroid disease, kidney cancer and testicular cancer.
"PFAS-laden pesticides are also used inside homes, for flea treatments on pets and in insect-killing sprays, noted the authors, who represent several environmental organizations.
"The researchers — from the Center for Biological Diversity, the Environmental Working Group and Public Employees for Environmental Responsibility — said they drew their conclusions by compiling data on sources of PFAS in pesticide products.
"Cordelia Saunders remembers 2021, the year she and her husband, Nathan, found out that they’d likely been drinking tainted water for more than 30 years. A neighbor’s 20 peach trees had finally matured that summer, and perfect-looking peaches hung from their branches. Cordelia watched the fruit drop to the ground and rot: Her neighbor didn’t dare eat it.
"The Saunderses’ home, in Fairfield, Maine, is in a quiet, secluded spot, 50 minutes from the drama of the rocky coast and an hour and 15 minutes from the best skiing around. It’s also sitting atop a plume of poison.
"For decades, sewage sludge was spread on the corn fields surrounding their house, and on hundreds of other fields across the state. That sludge is suspected to have been tainted with PFAS, a group of man-made compounds that cause a litany of ailments, including kidney and prostate cancers, fertility loss, and developmental disorders. The Saunderses’ property is on one of the most contaminated roads in a state just waking up to the extent of an invisible crisis.
Onur Apul, an environmental engineer at the University of Maine and the head of its initiative to study PFAS solutions, told me that in his opinion, the United States has seen 'nothing as overwhelming, and nothing as universal' as the PFAS crisis. Even the #DDT crisis of the 1960s doesn’t compare, he said: DDT was used only as an insecticide and could be banned by banning that single use. PFAS are used in hundreds of products across industries and consumer sectors. Their nearly 15,000 variations can help make pans nonstick, hiking clothes and plumber’s tape waterproof, and dental floss slippery. They’re in performance fabrics on couches, waterproof mascara, tennis rackets, ski wax. Destroying them demands massive inputs of energy: Their fluorine-carbon bond is the single most stable bond in organic chemistry."
