Apple bans use of 2 hazardous chemicals in iPhone assembly

“Five months after the activist groups China Labor Watch and Green America launched a petition drive calling on Apple Inc. to abandon the use of benzene and n-hexane in the production of iPhones,” Apple has done just that, according to The Associated Press.

“Apple says a four-month investigation at 22 factories found no evidence that benzene and n-hexane was endangering the roughly 500,000 people who work at the plants,” AP reports. “The Cupertino, California company nevertheless decided the substances should no longer be allowed during the final assembly process.”

    1. Who needs the Chemical Rubber Handbook when they can consult you? BTW, what are the ionic transport mechanisms in conducting polymers? We are looking into the Arrhenius model in assessing the stability of CD-R media in a humid environment. Salinity is an issue. We’ll cite you in the paper.

      1. ACK! Thou hast overmuch challenged my alchemical erudition.

        All I can do is point you to Kodak’s studies of the subject:

        For those interested:

        What is the Arrhenius Model?
        The Arrhenius Model is an excellent tool for exploring the relationship between activation energy and the speed of a chemical reaction. This equation has many scientific uses including calculating the rate of decay of a CD-R disc. The equation takes its name from Svante Arrhenius, the Swedish chemist who first explored the idea of activation energy in a reaction.

  1. Lol this is safety gone mad. I use n-hexane almost daily at work, it’s a very useful solvent not sure how Apple has replaced it. Probably with another “evil” sounding solvent…

    N-hexane, in huge quantities, is even used in the food industry to extract cooking oil from corn or seeds.

    Samsung must be laughing (and maybe writing cheques), they’ll never ever ban such a thing.

    Maybe Apple should create a solvent of their own with a nice friendly name….

    1. You may wish to rethink your work flow: “N-hexane has been reported to be the most highly toxic member of the alkanes. When n-hexane is ingested, it causes nausea, vertigo, bronchial irritation, intestinal irritation and CNS effects. It has been reported that ~50 g of n-hexane may be fatal to humans. Furthermore, n-hexane is biotransformed to 2-hexanol and further to 2,5-hexanediol by cytochrome P450 mixed function oxidases by omega oxidation. 2,5-Hexanediol may be further oxidized to 2,5-hexanedione, which is neurotoxic and produces a polyneuropathy.”

      1. Hexane is used in many industries, as prevalent as formaldehyde probably. A number of years ago I was horrified to learn of trace hexane in a brand of Evening Primrose oil. That made me into an inveterate label-reader and toxin-non-ingester.

    1. As I have espoused for many years, the suffering of the souls of the damned is a remarkable renewable source of necromantic energy. Would that its most prominent exponents had not be burned at the stake, we might today be free of the tyranny of carbon fuels. 😎
