Answer laterQuestion : The term "e-waste" refers to:
Option 1: Waste generated by electronic devices
Option 2: Waste generated by industrial processes
Option 3: Waste generated by healthcare facilities
Option 4: Waste generated by construction activities
Correct Answer: Waste generated by electronic devices
Solution : The correct answer is (A) Waste generated by electronic devices.
The term "e-waste" refers to electronic waste, which includes discarded or obsolete electronic devices. These devices can include computers, laptops, smartphones, tablets, televisions, printers, refrigerators, and other electrical or electronic equipment. E-waste may also include components and parts of these devices.
E-waste is a growing concern due to the rapid advancement of technology, leading to shorter product lifecycles and increased electronic consumption. Improper disposal of e-waste can have harmful environmental and health impacts. Many electronic devices contain hazardous materials such as lead, mercury, cadmium, and flame retardants, which can contaminate soil, water, and air if not managed properly.
Proper management of e-waste involves recycling and responsible disposal to recover valuable materials and prevent environmental pollution. Recycling e-waste allows for the recovery of valuable metals and other components, reducing the need for raw material extraction and minimizing the environmental impact of electronic devices.
Question : Comprehension:
Read the given passage and answer the questions that follow.
Key factors influencing subway air pollution will include station depth, date of construction, type of ventilation (natural or air conditioning), types of brakes (electromagnetic or conventional brake pads) and wheels (rubber or steel) used on the trains, train frequency, and more recently, the presence or absence of platform screen-door systems.
In particular, much subway particulate matter is sourced from moving train parts such as wheels and brake pads, as well as from the steel rails and power supply materials, making the particles predominantly iron-containing.
To date, there is no clear epidemiological indication of abnormal health effects on underground workers and commuters. New York subway workers have been exposed to such air without significant observed impacts on their health, and no increased risk of lung cancer was found among subway train drivers in the Stockholm subway system.
But a note of caution is struck by the observations of scholars who found that employees working on the platforms of Stockholm underground, where PM concentrations were greatest, tended to have higher levels of risk markers for cardiovascular disease than ticket sellers and train drivers.
The dominantly ferrous particles are mixed with particles from a range of other sources, including rock ballast from the track, biological aerosols such as bacteria and viruses, and air from the outdoors, and driven through the tunnel system on turbulent air currents generated by the trains themselves and ventilation systems.
Question:
Inferring from the passage, what is the most practical way of reducing the health risk of subway life?
Option 1: Generating ventilation systems.
Option 2: Opting for other transportation modes.
Option 3: Wearing face masks during journey.
Option 4: Reducing subway commutation.
Correct Answer: Generating ventilation systems.
Solution : The correct choice is the first option.
The passage mentions factors influencing subway air pollution. It also discusses the observation that employees working on platforms with higher particulate matter concentrations tend to have higher levels of risk markers for cardiovascular disease. Therefore, improving ventilation systems in the subway environment could be a practical measure to reduce the health risks associated with subway life.
Therefore, generating ventilation system is the most practical way of reducing the health risk of subway life.
