EPA takes closer look at confidentiality of safety studies under TSCA
The US EPA says that it is going to be "much more careful" with how it approaches the protection of confidential business information (CBI), following public outcry over its withholding of health and safety data supporting a TSCA risk evaluation.

Speaking last week at the GlobalChem conference in Washington, DC, Office of Chemical Safety and Pollution Prevention Assistant Administrator Alexandra Dunn said that the agency has learned from the controversy over its draft evaluation of pigment violet 29 (PV29).

The draft evaluation, released last November, relied in part on 20 studies submitted to Echa, when the substance was registered under REACH, that were protected as CBI. But several consumer advocacy groups protested that health and safety data cannot be withheld and filed a public records request to gain access to them.

In her public remarks, Ms Dunn acknowledged that the agency has received "a lot of very strong feedback" on its PV29 review.

And the government shutdown, she said, forced a delay to the peer review process and gave the EPA more time to think about those comments and "address the perception – real, or perceived (since perception is reality for many people) – how we can be more transparent in the work we’re doing."

Pigment violet 29 presents a low risk to human health and the environment, U.S. EPA says
colorant described as dark red-purple or bordeaux, pigment violet 29 is used in inks, paints, coatings, and plastics. It also “does not present an unreasonable risk of injury to human health or the environment under the conditions of use,” according to a draft risk evaluation prepared by the U.S. Environmental Protection Agency. EPA assessed pigment violet 29 under the updated Toxic Substances Control Act (TSCA), which was overhauled in 2016. EPA based its risk evaluation on the properties of the pigment, including its “low solubility, low vapor pressure, low bioaccumulation potential, and poor absorption across all routes of exposure,” as well as manufacturing and use information and environmental data, the agency says. However, EPA appears to have discounted some environmental hazards, foreseeable uses, and manufacturing that fall below reporting thresholds for individual companies, says Rep. Frank Pallone Jr. (D-N.J.) in a statement. “We look forward to holding hearings on this draft and EPA’s broad efforts to undermine” the updated TSCA provisions, adds Pallone, who is likely to become chair of the House of Representatives Committee on Energy & Commerce when Democrats take control of the House in January.

Algaemy - crafting our future food (Blond & Bieber) von Rasa Weber on Vimeo
An eco-friendly textile dye made from algae
Blond and Bieber’s Algaemy project investigates the creative possibilities of various forms of algae. Textile designer Essi Johanna Glomb and product designer Rasa Weber are the duo behind Blond and Bieber – a Berlin-based design studio interested in developing processes and concepts as types of modern day rituals. The step-by-step narrative of the studio’s latest project, Algaemy, reveals the ceremonial process involved in turning algae into a non-toxic textile dye.

Blond and Bieber’s work occupies an experimental space somewhere in between product and textile design. Because the design process is a central focus for the studio, textile acts as the physical tool with which to explore the thinking and story behind a concept.

In Algaemy, Glomb and Weber investigate the colour properties and creative possibilities of various forms of micro algae. While researching algae’s diverse usages across assorted industries, the designers were drawn to the vibrant pigmentations found in the organisms and how it could be used as a dye in the textile printing industry.

This led to a scientific project that involves growing algae in glass by blowing carbon dioxide into the glass bottles to aid photosynthesis. The algae is then filtered through fabric and made into a naturally pigmented paste, which can be used as an eco-friendly and completely non-toxic dye. The duo plan to introduce the algae dye to the market by designing a range of textiles with the paste.

American Academy of Pediatrics on Food Additives and Child Health
Our purposes with this policy statement and its accompanying technical report are to review and highlight emerging child health concerns related to the use of colorings, flavorings, and chemicals deliberately added to food during processing (direct food additives) as well as substances in food contact materials, including adhesives, dyes, coatings, paper, paperboard, plastic, and other polymers, which may contaminate food as part of packaging or manufacturing equipment (indirect food additives); to make reasonable recommendations that the pediatrician might be able to adopt into the guidance provided during pediatric visits; and to propose urgently needed reforms to the current regulatory process at the US Food and Drug Administration (FDA) for food additives.

Concern regarding food additives has increased in the past 2 decades, in part because of studies in which authors document endocrine disruption and other adverse health effects. In some cases, exposure to these chemicals is disproportionate among minority and low-income populations. Regulation and oversight of many food additives is inadequate because of several key problems in the Federal Food, Drug, and Cosmetic Act. Current requirements for a “generally recognized as safe” (GRAS) designation are insufficient to ensure the safety of food additives and do not contain sufficient protections against conflict of interest. Additionally, the FDA does not have adequate authority to acquire data on chemicals on the market or reassess their safety for human health. These are critical weaknesses in the current regulatory system for food additives. Data about health effects of food additives on infants and children are limited or missing; however, in general, infants and children are more vulnerable to chemical exposures.

Substantial improvements to the food additives regulatory system are urgently needed, including greatly strengthening or replacing the “generally recognized as safe” (GRAS) determination process, updating the scientific foundation of the FDA’s safety assessment program, retesting all previously approved chemicals, and labeling direct additives with limited or no toxicity data.

The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson - Free Ebook
"Here I proceeded to examine its contents. The powders were neatly enough made up, but not with the nicety of the dispensing chemist; so that it was plain they were of Jekyll's private manufacture; and when I opened one of the wrappers I found what seemed to me a simple crystalline salt of a white colour. The phial, to which I next turned my attention, might have been about half-full of a blood-red liquor, which was highly pungent to the sense of smell and seemed to me to contain phosphorus and some volatile ether. At the other ingredients I could make no guess. The book was an ordinary version-book and contained little but a series of dates. These covered a period of many years, but I observed that the entries ceased nearly a year ago and quite abruptly. Here and there a brief remark was appended to a date, usually no more than a single word: "double" occurring perhaps six times in a total of several hundred entries; and once very early in the list and followed by several marks of exclamation, "total failure!!!" All this, though it whetted my curiosity, told me little that was definite. Here were a phial of some tincture, a paper of some salt, and the record of a series of experi-"

Small chemical spill cleaned up in residential neighborhood
LUBBOCK, Texas - Lubbock Fire Rescue was called Wednesday afternoon to the 2200 block of Flint Avenue for the report of a small chemical spill.
