Your smartphone batteries emit over 100 toxic gases!

October 21, 2016

Washington, Oct 21: More than 100 potentially fatal gases are produced by the batteries found in billions of consumer devices such as smartphones and tablets, a new study has warned.

The research identified over 100 toxic gases released by lithium batteries, including carbon monoxide, which can cause strong irritations to the skin, eyes and nasal passages and harm the wider environment.

Researchers from the Institute of NBC Defence in the US and Tsinghua University in China said many people may be unaware of the dangers of overheating, damaging or using a disreputable charger for their rechargeable devices.

In the new study, they investigated a type of rechargeable battery, known as a "lithium-ion" battery, which is placed in two billion consumer devices every year.

"Nowadays, lithium-ion batteries are being actively promoted by many governments all over the world as a viable energy solution to power everything from electric vehicles to mobile devices," said Jie Sun, lead author and professor at the Institute of NBC Defence.
"The lithium-ion battery is used by millions of families, so it is imperative that the general public understand the risks behind this energy source," said Sun.

Sun and her colleagues identified several factors that can cause an increase in the concentration of the toxic gases emitted. A fully charged battery will release more toxic gases than a battery with 50 per cent charge, for example.

The chemicals contained in the batteries and their capacity to release charge also affected the concentrations and types of toxic gases released.

Identifying the gases produced and the reasons for their emission gives manufacturers a better understanding of how to reduce toxic emissions and protect the wider public, as lithium-ion batteries are used in a wide range of environments.

"Such dangerous substances, in particular carbon monoxide, have the potential to cause serious harm within a short period of time if they leak inside a small, sealed environment, such as the interior of a car or an airplane compartment," Sun said.

Almost 20,000 lithium-ion batteries were heated to the point of combustion in the study, causing most devices to explode and all to emit a range of toxic gases.

Batteries can be exposed to such temperature extremes in the real world, for example, if the battery overheats or is damaged in some way.

The researchers now plan to develop a detection technique to improve the safety of lithium-ion batteries so they can be used to power the electric vehicles of the future safely.

"We hope this research will allow the lithium-ion battery industry and electric vehicle sector to continue to expand and develop with a greater understanding of the potential hazards and ways to combat these issues," Sun concluded.

The study was published in the journal Nano Energy.

Mangaluru: This year too, the Mangaluru International Airport has missed being designated as an embarkation point for the annual hajj pilgrimage. 

According to the Haj Committee of India, not many are choosing Mangaluru as an embarkation point. Last year, although Mangaluru was notified as one of the embarkation points, the Union government removed it from the list at the last minute.

Several associations and organisations submitted memorandums to the Haj Committee of India, requesting the reinstatement of Mangaluru as one of the embarkation points, but their efforts have not materialised this year either.

The use of Mangaluru Airport as an embarkation point for the haj began in 2010. In 2019, 1,400 haj pilgrims flew from MIA to Saudi Arabia.

“When the number is less, it is difficult to consider it. It was the same issue as last year,” reacted AP Abdullakutty, chairman of the Haj Committee of India.
Mangaluru as an embarkation point served people from undivided Dakshina Kannada, Kodagu, Shivamogga, Uttara Kannada, and Chikkamagaluru districts.
Last year, the Muslim Central Committee of Dakshina Kannada and Udupi districts submitted a memorandum to Abdullakutty. They expressed their disappointment with Abdullakutty and stated that Mangaluru had a good number of applicants ever since it was identified as an embarkation point. 
Now, they have to travel to Bengaluru. 

UT Khader, speaker of the Karnataka legislative assembly, pointed out that several Union ministries are involved in the process of designating embarkation points for the haj.

“We are not sure why MIA as an embarkation point was removed. Is it because of fewer applications, or are airlines not willing to bid for MIA as an embarkation point? Is it only an issue with MIA as an embarkation point, or are there other airports in the country facing similar issues? We will try to find out and seek answers. Meanwhile, we will also start working at the earliest so that MIA is considered as an embarkation point for hajj next year,” said Khader.

Hubballi, Apr 23: Karnataka Chief Minister Siddaramaiah on Tuesday spoke to father of slain student Neha Hiremath over phone and said "sorry" over his daughter's killing, and assured that "we will be on your side".

The Chief Minister also informed Niranjan Hiremath, who is also a Congress councillor of Hubballi-Dharwad Municipal Corporation, about the government's decision to hand over the murder case to the Criminal Investigation Department (CID) and setting up a special court to fast-track trial.

"Niranjan... very sorry. We will be on your side," Siddaramaiah told Hiremath over the phone call during state's Law and Parliamentary Affairs Minister H K Patil's visit to Hiremath's house here.

In the conversation on Patil's phone with speakers on, Siddaramaiah can be heard informing Hiremath about the CID probe and setting up a special court.

"It is a serious offence... setting up a special court will ensure punishment for the accused person."

Hiremath thanked Siddaramaiah on behalf of his family well-wishers and the community for handing over the case to CID and setting up a special court "...ensure there is an order at the earliest and provide us justice," he said, as he also thanked Patil, Home Minister G Parameshwara, local Congress MLA Prasad Abbayya and others for their support.

Replying to this, Siddaramaiah said, "We will ensure it, at the earliest."

In a shocking incident, Neha Hiremath (23), was stabbed to death on the campus of BVB College last Thursday. The accused Fayaz Khondunaik, who fled from the scene, was arrested by the police subsequently.

Neha was a first year Master of Computer Application (MCA) student and Fayaz was earlier her classmate.

Siddaramaih on Monday had announced his government has decided to hand over the investigation into the incident to the Crime Investigation Department, and to set up a special court for speedy disposal of the case.

The case of brutal murder, which sparked widespread outrage, has snowballed into a political slugfest between ruling Congress and opposition BJP.

While the ruling party has tried to project it as an incident with personal angle, the saffron party has called it a "love jihad" case and has said it's a testimony of deterioration of law and order in the state.

Earlier, Siddarmaiah's statement that the murder was due to "personal reasons" and Home Minister G Parameshwara's comments that the duo was in love, has elicited sharp reactions from Hiremath and family members and opposition parties.

Gowdaprajwal.jpg

The JD(S) on Tuesday, April 30, announced that former Indian Prime Minister HD Deve Gowda's grandson Prajwal Revanna has been suspended from the party temporarily until allegations against him over sexual abuse are probed.

Revanna and his father HD Revanna, also a JD(S) MLA, were booked on Sunday by the police for sexual harassment and criminal intimidation based on a complaint from a woman, who worked in their household.

"We welcome SIT against Prajwal Revanna. We've taken a decision to recommend our party's national president to suspend him from the party till the SIT investigation is completed, " JD(S) core committee president GT Devegowda said.

Revanna currently is not in India. Opposition members raised concerns over how he was allowed to leave the country.

"A decision was already made. Tomorrow it is to be recommended at the core committee meeting in Hubballi. Because he (Prajwal) is a Member of Parliament, it has to be done from Delhi. So I had requested Deve Gowda (JD(S) National President and former PM). Neither he (Gowda) nor I were aware of this issue," party chief H D Kumaraswamy has said yesterday. "Some issues have come out, based on that it has been decided yesterday itself to suspend (him). But many were in a hurry."

Prajwal, 33, represents the BJP-JD(S) alliance in the Lok Sabha election in Hassan, which happened on Friday.

Kumaraswamy alleged that Congress was manipulating facts to destroy the image of his family amid the controversy over the 'obscene' video case against his nephew Prajwal.

"We are not going to protect him, we will take severe action but the government's responsibility is more," Kumaraswamy said.

"This is the manipulation of Congress to destroy the image of our family. What is the role of Dewegowda Ji or me? We are not responsible for all those things. This is the individual issue of Prajwal Revanna. I am not in contact with him (Prajwal). It is the responsibility of the government to bring him before the law. Morally we have decided to make some decisions," Kumaraswamy told reporters on Tuesday.

Prajwal Revanna sex scandal

The state government under CM Siddaramaiah has formed a Special Investigation Team to look into the matter. In recent days, certain explicit video clips purportedly featuring Prajwal have circulated in Hassan.

In response, Revanna stated his willingness to cooperate with any investigation regarding the allegations of sexual abuse against his son and himself. He affirmed their readiness to accept any legal consequences if the accusations are substantiated.

Prajwal's father HD Revanna said that his son would appear for an SIT probe whenever he is asked to.

A case of sexual harassment and stalking was registered on Sunday against HD Revanna and Prajwal Revanna at Holenarasipur police station based on a complaint by their cook.

The complainant said she is a relative of Revanna's wife Bhavani.

She claimed that four months into her employment, Revanna began sexually harassing her, while his son Prajwal engaged in video calls with her daughter, engaging in "vulgar conversations."

She also alleged that there is a threat to her life as well as other members of her family.
