Environmental organizations China Labor Watch and Green America called on Apple to “stop the unnecessary exposure of workers at Chinese facilities production to toxic chemicals that cause very serious illnesses.”
China Labor Watch told the Guardian, "Together with Green America, we demand that Apple take responsibility and not use chemicals such as solvents. n-hexane and the carcinogen benzene, which is known to cause leukemia to the workers."
Apple suppliers use solvents and benzene because it dries three times faster than traditional solvents, allowing employees to clean screen glass faster. Excessive exposure to n-hexane can cause nerve damage, even paralysis, according to doctors
The Guardian has managed to have a statement from Apple about the accusations accused by the two environmental groups.
"For the past decade, Apple has been working to remove toxic substances such as lead, mercury, brominated flame retardants and PVC from products which is very safe for both workers and consumers. We will require our suppliers worldwide to adhere to the safety standards of Osha, of the National Institute for Occupational Safety and Health, and American Conference of Governmental Industrial Hygienists.”
