DRIVERS-TREATMENT-TTHM-POLLUTION-SCARCITY-FUNDING Disinfection by-products (DBP) are a class of chemical by-products also referred to as trihalomethanes (THMs), formed when chlorine or bromine interacts with the natural organic materials found in water. DBPs also include other formed products, such as haloacetic acids, haloacetonitriles, haloketones, and chlorophenols. The composition and levels of specific DBPs are determined by water quality, water treatment conditions, and disinfectant type (IPCS, 2000). Primary sources of DBPs are chlorinated drinking water and recreational water bodies, such as swimming pools. In drinking water, trichloromethane is the predominant DBP, usually found at much higher levels than bromodichloromethane; tribromomethane is the least abundant (Krasner et al., 1989). DBPs are volatile at room temperature and can be detected in ambient air during activities such as showering, bathing, dishwashing, and swimming (Backer, et al., 2000; Gordon et al., 2006). Trichloromethane has industrial applications and is used to produce refrigerants and feedstock. It may be released into the environment where chlorine-based chemicals are used for bleaching and disinfecting processes or disposed at hazardous waste sites (IPCS, 2004; LaRegina, et al. 1986). Tribromomethane has limited industrial uses, mainly in geological assaying, electronics manufacturing, and as a solvent in laboratory analyses (ATSDR, 2005). DBPs tend not to bioaccumulate in aquatic organisms or persist in open or surface waters or soils, but they can remain in water within closed pipe systems. Workplace exposure may occur during the production of trichloromethane or tribromomethane, or in workplaces where DBPs may be generated, such as pulp or paper manufacturing, swimming pools, and water treatment plants (IPCS, 2004).
Tap Water and Trihalomethanes: Flow of Concerns Continues - 0 views

DRIVER-TTHMs-POLLUTION-PURITY-INFRASTRUCTURE-TREATMENT Trihalomethanes (THMs) are the result of a reaction between the chlorine used for disinfecting tap water and natural organic matter in the water. At elevated levels, THMs have been associated with negative health effects such as cancer and adverse reproductive outcomes. Now a study by government and academic researchers adds to previous evidence that dermal absorption and inhalation of THMs associated with everyday tap water use can result in significantly higher blood THM concentrations than simply drinking the water does [EHP 113:863-870]. The results of this exposure assessment study could serve as a guide for future epidemiologic investigations exploring the potential connection between THMs in tap water and adverse health effects.

Designers should ensure that spaces for all six modalities of work will be available as needed for both hypersensitive and hyposensitive occupants. While the right sizes and combinations of space will vary for each organization, the key is to provide a seamless array of choices. Spaces should easily adapt to the needs of people with work styles and behavioral needs at both ends of the spectrum. They also must be exceptionally flexible to integrate new technologies over time and, as more people continue to work remotely after the pandemic, to blend real and virtual work environments. Our current design is old and un-informed. We are ripe for a huge disruption in this space. I saw some recent pictures of Tesla's office. It's lame. How can you expect excellent and group breaking work when the environment is meh.
Elon Musk reminds us all that 'a bunch of people will probably die' going to Mars | Space - 1 views

"It's dangerous, it's uncomfortable, it's a long journey. You might not come back alive. But it's a glorious adventure, and it'll be an amazing experience," he said. "You might die ... and you probably won't have good food and all these things. It's an arduous and dangerous journey where you may not come back alive, but it's a glorious adventure," Musk said. Another indication that Musk doesn't really value humans.

Terraform Mars: After Inspiration4, Elon Musk hints at his long-term goal - 0 views

The comments hint at Musk's goal, stated multiple times over the years, that he would like to transform the planet's atmosphere to make it more hospitable to human life. It forms part of his overall goal with SpaceX: reduce spaceflight costs, use it to establish permanent human presences elsewhere in space, and transform humanity into a multi-planetary species. I absolutely love that he thinks about changing another planets atmosphere. For get changing the world, change a different planet. Amazing.
An expert explores how robots will affect the future of work | World Economic Forum - 0 views

A new survey-based study explains how automation is reshaping the workplace in unexpected ways. Robots can improve efficiency and quality, reduce costs, and even help create more jobs for their human counterparts. But more robots can also reduce the need for managers. What if more robots = a better quality of life. We always seem to go negative. What if we could work less, not more?
