International prevalence of fragrance sensitivity | SpringerLink
“Fragrance sensitivity” is a health condition characterized by adverse health effects from exposure to fragranced consumer products (Caress and Steinemann 2009). A “fragranced consumer product” (or “fragranced product”) is a product that contains an added fragrance or that is largely comprised of fragrance (Steinemann 2016). Fragranced products can include air fresheners, deodorizers, cleaning supplies, laundry detergents, fabric softeners, essential oils, scented candles, soaps, personal care products, colognes, and hand sanitizers, to name a few out of numerous everyday items. A single “fragrance” in a product is typically a complex mixture of dozens of compounds, many derived from petrochemicals (Sell 2006), among nearly 4000 documented fragrance ingredients (IFRA 2016).

No law in any country requires full disclosure of all ingredients in a fragrance. Instead of listing specific ingredients, a product may list the general term “fragrance” (or another legally accepted term, such as “perfume”). Further, no law requires full disclosure of all ingredients in a consumer product (other than for foods, drugs, and cosmetics), not even the general term “fragrance.” Thus, consumers have limited information about individual fragrance ingredients in a product as well as whether a product even contains a fragrance (Lunny et al. 2017; Steinemann 2009).

Exposure to fragranced products has been associated with a range of adverse human health and societal effects among the general population, and especially among vulnerable sub-populations such as individuals with asthma (Weinberg et al. 2017; Steinemann 2018c; Steinemann et al. 2018), autism (Steinemann 2018d), and chemical sensitivity (Steinemann 2019). Fragrance sensitivity can also be considered a disabling health condition that is covered under disability legislation in certain countries. However, relatively little research has investigated the prevalence of fragrance sensitivity, and more specifically links between fragranced consumer products and adverse health and societal effects.

This study investigates the effects of exposure to fragranced products on adults in four countries: United States (US), Australia (AU), United Kingdom (UK), and Sweden (SE). It builds upon and extends the individual national studies in the US, AU, UK, and SE (Steinemann 2016, 2017a, 2018a, b), offering greater breadth and depth of analysis, including new data and results on specific fragranced product exposures associated with specific health effects, amounts and costs of lost workdays and lost jobs, and comparisons and summaries across countries.

kaberett | Some sexism 101 I've just left as several comments on Facebook
... in response to a dude being shitty when a mutual (male) friend shared this tumblr OP. He started out doubling down but after Our Host told him his behaviour was unacceptable, he put himself on timeout and then came back and did actually ask me to explain, yes, really, he was interested and wanted me to now, and I... wrote 3k words. Which I don't want to have just... disappear into the bowels of Facebook. (And would quite like some validation on.)

Understanding genetic ancestry testing
Genetic ancestry testing is the use of DNA information to make inferences about someone’s "deep" ancestry, hundreds or thousands of years into the past. Genetic genealogy on the other hand combines DNA testing with genealogical and historical records, and typically makes use of large databases to identify matches, or direct comparisons to test for expected matches. There is some overlap between the two, but genetic genealogy is generally more reliable because of its use of additional information...

"Crack Babies' Aren't Harmed by Cocaine, but by Poverty"
Now, after nearly a quarter century, the federally funded study was ending, and the question the researchers had been asking was answered.

Did cocaine harm the long-term development of children like Jaimee, who were exposed to the drug in their mother's womb?

The researchers had expected the answer would be a resounding yes. But it wasn't. Another factor would prove far more critical.

Ruth Patrick, a Pioneer in Science and Pollution Control Efforts, Is Dead at 105 -
worked for free for

--- begin forward ---
Dr. Patrick built her career around research on thousands of species of single-cell algae called diatoms, which float at the bottom of the food chain. She showed that measuring the kinds and numbers of diatoms revealed the type and extent of pollution in a body of water. Her method of measurement has been used around the world to help determine water quality.

Dr. Patrick’s studies led to the insight that the number and kinds of species in a body of water — its biological diversity — reflected environmental stresses. That idea became known as the Patrick Principle, a term coined by the conservation biologist Thomas Lovejoy. In an interview, Dr. Lovejoy, of the H. John Heinz III Center for Science, Economics and the Environment in Washington, said the principle can be applied to bigger settings, like an entire ecosystem, and lies at the heart of environmental science.

Four years after her PhD, she worked seven years for FREE

She began her association with the Academy of Natural Sciences, which had the best collection of diatoms in America, as a graduate student in 1933. In 1937, she became an assistant curator of microscopy, an unpaid position. Only in 1945 was she put on the payroll, and two years later she established the limnology department, now called the Patrick Center for Environmental Research. She was its chairwoman until 1973, when she was named to the Francis Boyer chair of limnology. From 1973 to 1976 she was chairwoman of the academy’s board.
