Acid Bath: In this method, the e-waste is soaked in solutions of sulphuric, hydrochloric, and nitric acids to get the metal
            out. The salvaged metal is then used to make other things. However, acid solutions are difficult to dispose of. Releasing
            acids into water is bad for  living things.
            Mechanical recycling: The most effective and environmentally responsible method is to recycle. In this method, used
            circuit boards, ICs, motherboards, and other parts are taken from e-waste and recycled by dry physical separation.
            A printed circuit board (PCB) recycling machine may be used to separate precious metals like copper, lead, and other
            metals from e-waste.
            8.10.2 Awareness about Health Concerns

            Technology has had a great impact on our social and cultural environment. The technology revolution, especially the
            Internet, has changed everything, from education to entertainment to health to how we celebrate holidays and how
            we talk to our friends, family, and coworkers.  While technology has brought numerous benefits and advancements,
            it is crucial to understand and address potential health risks associated with its use. Here are some common health
            concerns related to technology:
            1.  Computer vision syndrome: Spending long hours in front of screens, such as computers, smartphones, and tablets,
               can lead to eye strain, dryness, blurred vision, and headaches. This is often referred to as computer vision syndrome.
               To mitigate these effects, it is recommended to take regular breaks, adjust screen brightness, use proper lighting,
               and follow the 20-20-20 rule (look at something 20 feet away for 20 seconds every 20 minutes).
            2.  Sleep disturbances: The use of technology, particularly before bedtime, can negatively impact sleep quality. The
               blue light emitted by screens can interfere with the production of melatonin, a hormone that regulates sleep. It is
               advisable to limit screen time before bed and use features like night mode or blue light filters on devices.
            3.  Musculoskeletal problems: Prolonged use of technology, especially when adopting poor posture, can contribute
               to musculoskeletal issues such as neck and back pain, shoulder strain, and repetitive strain injuries. Maintaining
               ergonomic setups, taking regular breaks, and practicing good posture can help alleviate these problems.
            4.  Mental health issues: Excessive use of technology, especially social media, can contribute to mental health concerns
               such as anxiety, depression, loneliness, and poor self-esteem. It is important to balance screen time, engage in
               offline activities, and cultivate healthy social interactions.
            5.  Electromagnetic radiation: Some individuals express concerns about the potential health effects of prolonged
               exposure  to  electromagnetic  fields  emitted  by  devices  such  as  smartphones,  Wi-Fi  routers,  and  power  lines.
               However, scientific research has not established clear evidence of harmful effects at typical exposure levels.
            6.  Digital addiction: The constant availability and engagement offered by technology can lead to addictive behaviors,
               where individuals struggle to control their use of devices. This addiction can have adverse effects on mental health,
               relationships, productivity, and overall well-being. Setting boundaries, practicing digital detox, and seeking support
               when needed are important steps in addressing digital addiction.

            To  address  these  concerns,  it  is  essential  to  promote  digital  literacy  and  encourage  responsible  technology  use.
            Educating individuals about healthy habits, advocating for breaks, promoting a balanced lifestyle, and fostering mindful
            technology  usage  can  help  mitigate  potential  health  risks  associated  with  technology.  Additionally,  researchers,
            industry professionals, and policymakers are continuously working on developing guidelines and technologies that
            prioritize user health and well-being.

                     1.  E-waste management techniques
                     2.  Health concerns related to technology
