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.

The Karnataka government's decision to categorise the entire Muslim community as a backward caste for reservation purposes in the state has drawn criticism from the National Commission for Backward Classes (NCBC), which said such blanket categorisation undermines the principles of social justice.

According to the data submitted by the Karnataka Backward Classes Welfare Department, all castes and communities within the Muslim religion have been enlisted as socially and educationally backward classes under Category IIB in the State List of Backward Classes.

The NCBC, during a field visit last year, examined the state's reservation policy for OBCs in educational institutions and government jobs.

"All castes/communities of Muslim religion of Karnataka are being treated as socially and educationally backward classes of citizens and listed as Muslim Caste separately under Category IIB in the State List of Backward Classes for providing them reservation in admission into educational institutions and in appointments to posts and vacancies in the services of the State for the purpose of Articles 15(4) and 16(4) of the Constitution of India," the NCBC said in a statement on Monday night.

This categorisation has led to the provision of reservation benefits for 17 socially and educationally backward castes under Category I and 19 castes under Category II-A, respectively.

The NCBC said the blanket categorisation of Muslims as a backward caste undermines the principles of social justice, particularly for the marginalised Muslim castes and communities identified as socially and educationally backward.

However, the NCBC emphasised that while there are indeed underprivileged and historically marginalised sections within the Muslim community, treating the entire religion as backward overlooks the diversity and complexities within Muslim society.

"The religion-based reservation affects and works against ethics of social justice for categorically downtrodden Muslim castes/communities and identified socially and educationally backward Muslim castes/communities under Category-I (17 Muslim castes) and Category II-A (19 Muslim castes) of State List of Backward Classes. Hence, socially and educationally backward castes/communities cannot be treated at par with an entire religion," the NCBC stated.

The NCBC also voiced concern over the impact of such reservations on the overall framework of social justice, particularly in the context of local body polls.

While Karnataka provides 32 per cent reservation to backward classes in local body elections, including Muslims, the Commission stressed the need for a nuanced approach that accounts for the diversity within these communities.

According to the 2011 Census, Muslims constitute 12.92 per cent of the population in Karnataka.

Bengaluru: With six children of Karnataka Ministers in the Lok Sabha poll arena, the campaign scene is getting spiced up in the high-stakes elections for the ruling Congress in the state. Prabha Mallikarjun, wife of Minister S S Mallikarjun, is also in the poll fray.

The grand old party tried its best to make several ministers enter the Lok Sabha election fray but none of them agreed and, instead, they proposed the candidature of their family members.

'Now, deliver' is the stern message of the Congress leadership to the ministers, putting the onus on them to ensure the victory of their kin, according to party sources.

The Congress secured only one seat in Karnataka in the 2019 general elections, and has now set an ambitious target of winning in 15 to 20 constituencies in the coming polls.

Elections in 28 constituencies in the State will be held in two phases on April 26 and May 7.

Sons of Laxmi Hebbalkar, Eshwar Khandre and H C Mahadevappa— Mrinal Ravindra Hebbalkar, Sagar Khandre and Sunil Bose— have been fielded from Belagavi (Belgaum), Bidar and Chamarajanagar, respectively.

Daughters of Satish Jarkiholi, Shivanand Patil and Ramalinga Reddy— Priyanka Jarkiholi, Samyukta Patil and Sowmya Reddy— are in contention in Chikkodi, Bagalkot and Bangalore South respectively.

Prabha Mallikarjun, wife of Minister S S Mallikarjun and daughter-in-law of veteran party leader Shamanur Shivashankarappa, is the party's nominee from Davangere.

"In this 'do or die' situation, the ministers have found the Lok Sabha election a launch pad for their children and relatives. We have to see how these ministers succeed in their mission," a Congress insider said.

Barring Sowmya Reddy, who is a former MLA, none of them have any legislative experience in elections. Stakes are high for some other ministers as well.

The party has fielded Radhakrishna Doddamani, son-in-law of Congress President M Mallikarjun Kharge in the family's home turf of Kalaburagi (Gulbarga), a seat held by the BJP.

Kharge's son and Minister Priyank Kharge has taken charge of spearheading the campaign in this segment, where his father had lost in the 2019 general elections.

"Priyank has taken this election as a prestige issue given the fact that the Congress president hails from here and had represented this constituency in the past in the Lok Sabha," a Congress leader said.

Prime Minister Narendra Modi had last month launched the BJP's formal campaign in Kalaburagi in what was seen as an aggressive message to the Congress.

Karnataka Deputy Chief Minister and State Congress chief D K Shivakumar's brother D K Suresh is seeking reelection in Bangalore Rural, where the BJP and JD(S) have fielded noted cardiologist and son-in-law of former Prime Minister H D Deve Gowda.

The Congress which came to power in the state in May last year is seeking to ride on its five guarantee schemes of the government.

Sowmya Reddy, who is contesting from Bangalore South asked the women voters during a recent roadshow - "Do you travel in the buses? Which places have you visited in the recent past? Do you pay or travel for free?".

She was referring to 'Shakti' guarantee that offers free rides to Karnataka women in non-luxury government buses within the state. Reddy explained to the people about the four other guarantees— 'Gruha Lakshmi', 'Gruha Jyoti', 'Yuva Nidhi' and 'Anna Bhagya'.

"Who brought 'Achchhe Din'? Is it Congress or the BJP? Which 'Achchhe Din' you will vote for?" Reddy asked the women voters.

In Belagavi, Mrinal Ravindra Hebbalkar, is taking on BJP candidate and former Chief Minister Jagadish Shettar.

In campaign meetings, Minister Laxmi Hebbalkar reminded the crowd how Shettar had joined Congress when the BJP denied him a ticket in the 2023 Assembly election, only to return to the saffron party a few months later.

"Shettar is from Hubballi and we are from Belagavi. We know the problems prevailing here better than any 'outsider'. Today, BJP people are saying that they vote for Shettar keeping Prime Minister Narendra Modi in mind, but I want to know why he joined Congress and abused the BJP, Modi and former Chief Minister B S Yediyurappa," the minister asked.

The BJP swept the 2019 general elections in Karnataka winning 25 out of the 28 seats, while an independent backed by the party also won. The Congress and JD(S) which fought the elections together, secured one seat each.

New Delhi: Even though Prime Minister Narendra Modi's nasty election speech in Rajasthan's Banswara has triggered a nationwide controversy, the Election Commission has so far not taken any action. Meanwhile the Opposition bloc INDIA called the speech an attempt to divert attention from "real issues".

Addressing the people Banswara, on April 21, (Sunday) Modi openly attacked India’s Muslims, suggesting they were “infiltrators” and went on to claim that the opposition if elected would give away “mangalsutras” and “land” of those listening to his speech to them (Muslims). 

He referred to his immediate predecessor, Dr Manmohan Singh who was in office for 10 years as prime minister till 2014, and said, “Earlier, when his government was in power, he had said that Muslims have the first right on the country’s property, which means who will they collect this property and distribute it to – those who have more children, will distribute it to the infiltrators. Will the money of your hard work be given to the infiltrators? Do you approve of this?” 

Modi went on to say, “This Congress manifesto is saying that they will calculate the gold of the mothers and sisters, get information about it and then distribute it. Manmohan Singh’s government had said that Muslims have the first right on property. Brothers and sisters, these urban Naxal thoughts will not let even your mangalsutra escape, they will go this far.”

Narendra Modi and the BJP so far in their campaign trail have invoked religious faith, the Ram temple and Lord Ram multiple times, directly using it to call for people to vote for them. The Election Commission has been completely silent on the messaging via videos, tweets and other exhortations. 

Did Manmohan Singh really say that?

Modi’s claim that Dr Singh said that is not new and was refuted in 2006 itself by Singh’s PMO, when Modi had first made the false claim. The PMO had termed such remarks, “a deliberate and mischievous misinterpretation of what the Prime Minister said here yesterday at the meeting of the National Development Council, on fiscal priorities of the government.” It was termed “an avoidable controversy has been generated. The Prime Minister’s observations have also been quoted out of context in some sections of the electronic media, fuelling a baseless controversy.”

The full text of the paragraph in which the Prime Minister referred to the issue of minority empowerment to clarify the matter is as follows:

“I believe our collective priorities are clear: agriculture, irrigation and water resources, health, education, critical investment in rural infrastructure, and the essential public investment needs of general infrastructure, along with programmes for the upliftment of SC/STs, other backward classes, minorities and women and children. The component plans for Scheduled Castes and Scheduled Tribes will need to be revitalized. We will have to devise innovative plans to ensure that minorities, particularly the Muslim minority, are empowered to share equitably in the fruits of development. They must have the first claim on resources. The Centre has a myriad other responsibilities whose demands will have to be fitted within the over-all resource availability.”

The PMO’s clarification said. “it will be seen from the above that the Prime Minister’s reference to “first claim on resources” refers to all the “priority” areas listed above, including programmes for the upliftment of SCs, STs, OBCs, women and children and minorities.

Opposition reacts

Chairman, Media and Publicity department of the Congress, Pawan Khera said in a video message in a post, “We challenge the Prime Minister to show us if the word Hindu or Muslim is written anywhere in our manifesto. This kind of lightness is there in your mentality, in your political values. We have talked about justice for the youth, women, farmers, tribals, middle class and workers. Do you object to this as well?”

Khera was referring to earlier mistruths uttered by Modi about the “Muslim League” having influenced the Congress manifesto.

In Jharkhand’s Ranchi at an opposition rally, Congress president Mallikarjun Kharge is reported to have said by BBC Hindi, “If democracy and the Constitution end in the country, then the people will have nothing left. Babasaheb Ambedkar ji and Jawaharlal Nehru ji gave equal voting rights to everyone, due to which all classes got respect. But Narendra Modi wants to snatch their rights from the poor.”

B.V. Srinivas termed it as unfortunate that “this person is the Prime Minister of this country, and an even bigger tragedy is that the Election Commission of India is no longer alive.” He said that “due to the frustration of impending defeat, the Prime Minister of India is openly sowing the seeds of hatred, he is polarising by misquoting Manmohan Singh’s 18-year-old incomplete statement, But the Election Commission (Modi ka parivar) is bowing down.”

Modi’s past hate-speech

Modi, in his 12-year tenure as chief minister of Gujarat was known to have made speeches targeting the state’s minority Muslim community brazenly, terming camps where Muslims were forced to stay in after communal violence gripped the state in 2002. Frontline covered him on his Gujarat Gaurav Yatra started shortly after the violence, at a rally at Becharaji in Mehsana district in northern Gujarat, when he said, “What should we do? Run relief camps for them? Do we want to open baby-producing centres? But for certain people that means hum paanch, hamare pachees.” 

In 2017 it was time again for direct speech targeting Muslims when in February he spoke of ‘shamshaan versus kabristan’ campaigning for UP and then for Gujarat elections when the BJP had its worst performance this millennium, in a speech at Palanpur on December 10, 2017 Modi invoked a “secret meeting” to get Pakistan to fix Gujarat’s assembly polls. He said that a meeting was held at Congress leader Mani Shankar Aiyar’s residence, attended by former PM Manmohan Singh, former Vice-President Hamid Ansari, former Army Chief Deepak Kapoor and distinguished diplomats to execute the plot. Modi’s PMO faced embarrassment when in response to an RTI filed by the Congress, his office was forced to say that Modi’s campaign speech could have been based on an “informal input”.

In the only question he has answered as part of a press conference with Joe Biden on June 22, 2023, Modi was asked, “India has long prided itself as the world’s largest democracy, but there are many human rights groups who say that your government has discriminated against religious minorities and sought to silence its critics.  As you stand here in the East Room of the White House, where so many world leaders have made commitments to protecting democracy, what steps are you and your government willing to take to improve the rights of Muslims and other minorities in your country and to uphold free speech?”

In response Modi appeared visibly frazzled and denied all charges. “I’m actually really surprised that people say so.  And so, people don’t say it.  Indeed, India is a democracy.” 

The journalist was trolled online by BJP leaders and supporters to such an extent that the White House had to come out and defend her and strongly denounce the trolling and abuse.
