While working as a lab assistant in the chemistry department’s chemical storage room, I found a bottle of a reagent that had no received date, so I didn’t know how old it was and if I should toss it or use it. I asked me supervisor and she said, “Well, the manufacturer’s address on the label doesn’t have a zip code, so this has to be before zip codes were created in the 1960s.” It was that day that I realized that zip codes didn’t always exist. Mind blown.

High Levels of Toxins Found in Lipstick

A new analysis of the contents of lipstick and lip gloss may cause you to pause before puckering.

Researchers at the Univ. of California, Berkeley’s School of Public Health tested 32 different lipsticks and lip glosses commonly found in drugstores and department stores. They detected lead, cadmium, chromium, aluminum and five other metals, some of which were found at levels that could raise potential health concerns. Their findings published online today in the journal Environmental Health Perspectives.

"Huge stockpile of toxic waste in 12 provinces"

More China poison from civilization.

Amplify’d from www.chinadaily.com.cn

BEIJING - One million tons of untreated toxic industrial waste are piling up across China, risking environmental disasters like the recently exposed case in Yunnan province, a non-governmental organization has warned.

Earlier this month it was revealed that more than 5,000 tons of chromium residue were illegally dumped on roadsides and in mountains by a chemical factory in Yunnan’s Qujing city, causing the deaths of 77 head of livestock.

Official tests found “excessive sexivalent chromium” in water in the area where the waste was dumped.

Tests of the groundwater near the factory by Greenpeace, an environmental protection organization, showed that the concentration of sexivalent chromium in the water was 242 times the national standard.

Chromium residue is a heavy metal and hazardous waste residue generated in the production of chromium metal and chromium salt.

Hexavalent compounds in the residue are the most toxic. The soluble and unstable chemical may cause health problems, such as kidney and liver damage, after entering human bodies through respiration, the skin, mucous membranes and digestion of food.

The International Agency for Research on Cancer (IARC), part of the World Health Organization, lists these compounds as carcinogenic for humans.

A national remediation scheme for chromium residue pollution in 2005 showed more than 4 million tons of the chemical had been stockpiled untreated in 19 provinces. This led to official demands that the waste be disposed of safely by the end of 2010.

"Most of the waste was not properly disposed of, but directly discharged into the environment. Some of it was even dumped in important water sources and densely populated areas," reported the scheme published on the website of the National Development and Reform Commission, the country’s top economic planning agency.

It also said without decontamination, chromium residue had seriously polluted surface water, groundwater and soil, and posed a huge threat to people’s lives and property.

According to the 2010 Report on the State of the Environment in China, 3 million tons of the residue in seven provinces have been treated, which means there are still 1 million tons left untreated in 12 provinces.

Wang Peilin, deputy secretary-general of the China Inorganic Salts Industry Association, said in previous interviews the figure was 1.3 million tons.

"This Yunnan incident also confirmed that disposal of the waste was not completed by 2010, and was a warning for other businesses which had not completed their disposal tasks. We can no longer be sluggish in the management of waste," she said.

Official data shows China is the world’s largest producer and consumer of chromium with an annual production capacity of more than 300,000 tons. The chemical is widely used for the manufacture of stainless steel, leather and bicycle parts.

"Due to outdated technology, 3 to 5 tons of hexavalent chromium are generated when producing 1 ton of chromium," said Ma Tianjie, senior toxics prevention campaigner at Greenpeace.

He said this latest contamination incident once again showed the dangers of the development model of “pollution first, treatment later”.

[Fedora] Fixing SELinux Chromium / Chrome block

The problems occure while SELinux (something like Linux antivirus / firewall) and you need to add a permision for chrome to run some root libraries or something i don’t know for specific… So just switch to root user and enter these commands :
semanage fcontext -a -t textrel_shlib_t '/opt/google/chrome/chrome'

restorecon -v '/opt/google/chrome/chrome'

grep chrome-sandbox /var/log/audit/audit.log | audit2allow -M mypol

semodule -i mypol.pp


That’s it :]

A spike in the chromium contained in ancient rock deposits, laid down nearly 2.5 billion years ago, reveals what appears to be the earliest evidence for oxygen-breathing life on land.

The transformation known as the Great Oxidation Event occurred when the atmosphere gained oxygen, an element crucial for nearly all animal life, including humans. The new analysis indicates the earliest estimate to date for the start of the Great Oxidation Event  — 2.48 billion years ago. Other research has suggested small amounts of the gas appeared in the oceans and possibly the atmosphere around 2.5 billion years ago.

For this study, the researchers performed more than 2,000 analyses on samples from more than 100 rock formations, including those called banded iron formations, located around the world, from Canada to South Africa.

The Real Price of Leather

I’ve spent a lot of time recently sharing vegan fashion inspiration, much of which includes leather alternatives, especially for shoes and bags. I do this assuming that most people understand why wearing animals is so destructive, but every once in a while I hear a conversation or come across a naive comment that reminds me how crucial it is to spread the truth. Most consumers are so desensitized to the fact that the leather handbags, jackets, boots, sneakers, etc, hanging on racks throughout nearly every clothing store are made from a material that used to keep an animal alive. So, with that in mind, I wanted to share a few leather-related facts for you to learn from and/or share with others!

1) Most leather comes from China or India, where animal welfare laws are relatively nonexistent.

Shocked to see India as a leader of the leather trade? I was too, given the sacred nature of cows in the region, and the constitutional protection they are supposed to be granted. Sadly, the laws that protect them are easy to get around, and for the most part ignored.

Cows are transported from Hindu states to the Islamic states, where they can be slaughtered more openly. During this transportation, cows are often neglected, sometimes going days without food or water. When they collapse from exhaustion or dehydration, common methods of getting them to move include breaking their tails or smearing hot chili pepper into their eyes.

Between these horrors and the institutionalized mistreatment of all exploited animals in China, it’s safe to say that the vast majority of leather comes from animals who lived truly painful, sad, and fearful lives. Even if a leather product says it was made in America, Italy, or another country you trust, that definitely does not guarantee that the materials were sourced there.

2) Leather is not a by-product of the meat industry, it is a co-product.

Many people (myself formerly included), assume that avoiding leather won’t save any lives, because it’s just a by-product of the meat industry (and thus, not buying it would supposedly result in those hides being thrown away). The reality, however, is that leather is estimated to produce at least half of the profits for slaughterhouses that process cattle. The profit margin for cow meat is relatively small compared to that of leather, so many cattle processing companies rely on the leather trade to stay afloat.

Put more simply, boycott the flesh AND the skins if you want animal cruelty to be put out of business more quickly.

3) Leather tanning ranks #5 on the world’s most toxic pollution problems list.

We call it “leather” to avoid thinking about the source, but we must remember that this material is actually just the decomposing flesh of a once-living animal. If left untreated, it would be a pretty disgusting (and certainly not fashionable) sight, so the tanning process is a crucial phase in the leather production cycle. Tanning includes many steps, such as bleaching, dyeing, finishing, and shining- all of which require the use of harsh, destructive chemicals. The most noteworthy of these is chromium, a toxic chemical that, when rinsed off the hide, flows into local wastewater, causing a vast array of environmental issues. The chromium waste ends up in soil, air, food, and water, harming any animal or human who comes in contact with it. I don’t know about you, but I’d rather not find myself eating food that was contaminated by a known carcinogen

4) Employees in tanning factories suffer horrific injuries and illness

I know, vegans aren’t supposed to care about humans, right? Fortunately I don’t fit into that stereotype (nor do the majority of my compassionate vegan friends). Leather tanning often takes place in impoverished regions of China and India, where employees are not only given little to no money, but where they also risk their lives every day. Their exposure to chromium is of course dramatically higher, leading not only to possible cancer, but also eye damage, ulcerations, bronchitis, and holes in the nasal septum. Throw in the prevalence of child labor in some of these areas (the girl below stands outside a tanning factory in Bangladesh, another hot spot for leather tanning) and you have a pretty heartbreaking situation.

So, overall, the leather situation is pretty bleak. It’s horrific for animals, the environment, and humans, yet most people continue to support it despite the plethora of incredible alternatives coming to market every day! Please vote with your dollars to choose handbags, jackets, and shoes that are more aligned with your values, and together we’ll abolish this antiquated, destructive industry.

Diethyl ether and dimethyl sulfoxide. 

If a few drops of hexane is added to the ether, it will become completely immiscible with dimethyl sulfoxide, so useful compounds could be easily extracted from it, while highly polar inorganic salts remain in the DMSO. 

In this case I needed to extract a ketone from the DMSO what contained chromium(III) what caused this green color.

P.S.: did you know, that there is a blogger here on Tumblr with dimethylsulfoxide in its url? If not, let me introduce you an awesome chemistry blog: http://dimethylsulfoxide.tumblr.com/

Forget Google, Get DuckDuckGo

Why Google Needs To Go

Recently I’ve been attempting to purge Google from my online experience. If you are wondering why anyone would want to do this, here are three good reasons:

  1. Google stalks you - Every search you make is saved on Google’s servers, along with your IP address. They install cookies on your computer to track which pages you visit, how long you stay there, and so on. Basically, Google doesn’t care about privacy that much.
  2. Google engages in censorship - And not necessarily to block copyrighted content. If someone uses their services and does something Google doesn’t agree with they will have everything deleted and their accounts banned. Google also panders to governments everywhere by deleting content, handing over user information, and generally not following their “don’t be evil” motto.
  3. Google serves biased search results - Because Google engages in stalking, it knows a lot about you. Therefore, it serves search results that are tailored just for you. In this way, it will be less likely that you will be exposed to content that opposes your views. In effect, Google Search is a confirmation bias machine.

Why DuckDuckGo?

To get around this problem I have been looking for a Google replacement. The best one I have found so far is DuckDuckGo. They do not stalk you, they will not censor you, and they will serve search results that are not biased. I also wanted something that imitated Google’s minimalist approach to search, and DuckDuckGo does a better job than Google in my opinion. There are other search engines out there however I’ve personally settled for this one.

If this sounds like something you want to try, go to DuckDuckGo.com. If you want to make the change permanent, you can set it as your default search engine.

Google Chrome/Chromium:

  1. If you are using Google Chrome and don’t like other browsers, I suggest you switch to Chromium. Chrome will track you for Google even if you don’t use their online services.
    Download: Windows (32.7 MB) | Mac (35.3 MB)
  2. Go to DuckDuckGo.com.
  3. Once the page is loaded, go to Preferences/Settings>Basics>Search>Manage Search Engines. Under Other Search Engines hover the cursor over DuckDuckGo and click Make Default.

Firefox:

  1. Go to DuckDuckGo.com.
  2. Once the page is loaded, go to the search bar and click the icon with an arrow, then select Add DuckDuckGo.
  3. Click the icon again and select Manage Search Engines. Move DuckDuckGo to the top of the list and remove Google from the list, plus any other search engines you don’t want.

Safari:

  1. To edit search engines on Safari (Mac) you need to install an app called Glims.
    Download: Mac Only (8.6 MB)
  2. Open the DMG file you downloaded and follow the instructions.
  3. Once installed and Safari has been restarted, go to Safari>Preferences>Glims>Search Engine List and select DuckDuckGo. You can unselect Google and any other search engines you do not want to use.
  4. Finally, if you do not want favicons to appear in the tabs (Safari default) go to General>Improve Tabs and switch it off.
Usando mailto para Gmail no Chromium e Ubuntu 11.04

Não uso Thunderbird, Evolution ou qualquer programa de gerenciamento de email, prefiro usar o Gmail direto no navegador. Para esta função funcionar em perfeitas condições no Ubuntu existem duas aplicações possíveis:

Gnome Gmail e Desktop Webmail

Mas para mim isso não funcionou, não sei porque. Encontrei uma alternativa procurando no Google, mas tive que fazer algumas modificações.

  1. Entre em Aplicativos Preferencias;
  2. "Leitor de Email" selecione "Cliente de Email"
  3. Crie um arquivo na sua pasta principal, por exempo: “gmaildefault.sh”
  4. Cole o código abaixo e salve
  5. Execute um “mailto:” no Chromium e selecione para executar o arquivo “gmaildefault.sh”
  6. "Simples assim", haha.

Código:

#!/bin/sh

str=$(echo $1|sed ‘s/.*mailto:\([^?]*\)?.*/\1/’)

notify-send “Abrindo Gmail” “to: `echo $str`” -i /usr/local/share/icons/hicolor/48x48/apps/google-chrome.png -t 5000
