- Beyond the Headlines: Canada's environmental shortfalls; what clean water is worth.
In this week’s trip beyond the headlines, Environmental Health News and Daily Climate Publisher Peter Dykstra tells us about a scathing report about the Canadian government’s environmental shortfalls written by the Canadian government, the cash value of clean water and the invention of nylon stockings.
- Forward-thinking companies bet on green energy.
A couple of decades ago, two academic chemists developed 12 principles of green chemistry to guide the design of chemical products and processes which reduce or eliminate the use or generation of hazardous substances.
- Wonder stuff: Shrimp plus spider kills plastic.
Combine the hard stuff in shrimp shells with a spider silk protein and you get shrilk, a tough, biodegradable replacement for world-choking plastics.
- Making it with mushrooms.
For a more sustainable world, Ecovative Design’s marketing and sales manager says, industry will need to exploit processes found in nature. That’s the goal of a handful of companies developing mushroom plastics.
- Fish still contaminated with phased-out Scotchgard chemical.
A persistent chemical formerly used in Scotchgard still contaminates most fish in U.S. rivers and the Great Lakes despite a phase-out a dozen years ago, a new federal study shows.

- Cape Cod studies seek link between breast cancer, septic systems.
As advances continue in the detection and treatment of breast cancer, some argue that more investigation is needed into the root causes of the disease.
- Hand sanitizer may increase BPA absorption.
About 15 billion pounds of Bisphenol A, or BPA, are produced for commercial use each year. This week a new study in PLOS One, authored by endocrinologist Frederick vom Saal, reports that touching thermal paper after using hand sanitizer can increase the amount of BPA absorbed by the skin 100-fold.
- Why receipts and greasy fingers shouldn’t mix.
An order of French fries may be bad for your health in ways that extend well beyond the outsize calorie count. According to a new study by scientists at the University of Missouri, people who used hand sanitizer, touched a cash register receipt and then ate French fries were quickly exposed to high levels of bisphenol A (BPA), a chemical widely used to coat receipt paper.
- Controversial chemical may leach into skin from cash receipts.
Touching cash register receipts can dramatically increase your body's absorption of a potentially dangerous chemical, bisphenol A (BPA), researchers report. The chemical is found in products ranging from plastic water bottles and food-can linings. It is also used as a print developer in thermal paper for airline tickets and store and ATM receipts, according to the researchers.
- Hand sanitizer speeds absorption of BPA from receipts.
Though BPA in plastics has borne the brunt of public and media attention, it may be the paper that is most worrisome. A new study published today has found that BPA is absorbed more quickly and extensively when people apply hand sanitizers before handling receipts.
