published in the journal environmental pollution, the study establishes the links of these chemicals’ effect on the health of nail salon workers for the first time, forbes reports.

researchers at the university of colorado examined levels of chemicals known as volatile organic compounds (vocs) usually found in nail products. these include formaldehyde, a common organic specimen preservative widely “known to be a human carcinogen.”

research lead author lupita montoya noted: “the study provides some of the first hard evidence that these environments are dangerous for workers and that better policies need to be enacted to protect them.”

according to montoya, since over 90% of nail salons are small businesses, they rarely have the resources to enforce staff health and safety practices. most of them also declined to take part in the experiment.

in the study, her team soon discovered that air inside the salons contained formaldehyde and other toxic compounds. benzene, which has been previously linked to blood cancers, is among the potentially harmful chemicals.

then modeled the impact of the increased exposure to benzene and formaldehyde over 20 years on the risk of the workers developing certain types of cancer.

the cancer risk was determined according to thresholds set by the us environmental protection agency (epa) and the center for disease control and prevention.

based on their projections, the risk for developing lung cancer, head and neck cancer, and hodgkin’s lymphoma in all of the workers is increased up to 100 times after 20 years of exposure in such chemicals.

scientists warned that such a prolonged exposure has a similar effect to working an at oil refinery or garage who are at risk of developing cancer of the stomach, oesophagus, and lungs due to asbestos exposure.

however, researchers have noted that this does not pose as much danger to customers.

“it really depends on how much time you spend in and around that environment,” montoya was quoted as saying. “customers spend a fraction of the time in salons that workers do. unless they have pretty severe allergies or asthma, there’s not much for customers to be concerned about.”

the researchers recommend placing specially-treated wood or coal in nail salons as it could absorb airborne chemicals via “passive diffusion.”

users are questioning how spammers are able to access their phone number, and also why apple id and why the company has failed to offer effective filtering measures beyond reporting the spammers’ number.

even though iphone users report and delete the messages, next one keep on flooding in-and there seemingly is no solution to deal with it yet.

in february this year, apple handed over their icould operations in china to a chinese company, named guizhou-cloud big data  (云上贵州公司), to comply with government policies that require chinese citizens’ data to be held within the country. 

one user comments: “we didn’t have this [problem] before. only after guizhou-cloud took over did it occur. classic china.”

another weibo user wrote: “wake up everyone! state enterprise guizhou-cloud is responsible for icloud and is selling user data on the black market. why would you now blame apple for this problem???”

“i feel like i was in macau, hahaha.” someone added.

as a matter of fact, the following step could help you solve this problem, but it may affect your user‘ experience to a certain extent.

in settings-messages, turn off the button of imessage. then you can neither receive phone verification and notification nor send imessage.

besides imessage, fraud messages in iphone appeared more than often recently. 

what’s more,  the content and type are the same ones.

however, chinese workers are finding that such convenience comes at a price as company bosses increasingly use wechat to assign tasks to their employees.

now authorities in the xiangzhou district of the southern chinese coastal city of zhuhai are pushing back with proposed measures designed to separate work from play on the app. “no working messages should be sent to wechat working groups during non-working hours,” according to a proposal announced earlier this month on the district’s official wechat account.

the proposal comes at a time when communicating via wechat has become an extension of daily life for most chinese people due to the dominant position of the tencent-owned app in providing social media services.

wechat representatives did not immediately respond to requests for comment.

“wechat groups originally served to improve working efficiency but [with more and more groups forming] it has become a heavy working burden to employees,” said the proposal. “in principle, one company can only form one wechat group [and] the group for a project should be disbanded after it is done.”

the proposal also suggested that workers should not randomly send messages or post emojis in the wechat group unless it is related to important new information about the project.

the discussion went viral on the internet and struck a chord with chinese netizens, most of whom said they were dealing with the same problem.

“i really envy the people who work in xiangzhou,” said one netizen. “i hope the measures will be widely applied to all companies.”

“we have to respond to working messages every minute of the day,” another complained. “the boss knows i am always on wechat, so he expects me to respond immediately, even on the weekend.” 

some netizens were pessimistic that the measures in the proposal would be carried out by companies. “you are too naive if you believe it,” said another.
