Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
E-waste can be especially harmful due to
A
the heavy and toxic metals that can be released
B
the size and weight of most e-waste items
C
wildlife eating it and becoming ill or dying
D
the single-use “throw-away” design of most e-waste products
Explanation: 

Detailed explanation-1: -As mentioned, electronic waste contains toxic components that are dangerous to human health, such as mercury, lead, cadmium, polybrominated flame retardants, barium and lithium. The negative health effects of these toxins on humans include brain, heart, liver, kidney and skeletal system damage.

Detailed explanation-2: -Toxic metals (e.g., lead, mercury, nickel, and cadmium) are released to the environment from the e-waste and eventually enter into soil, sediment, groundwater, and surface water. The release of toxic metals in the environment causes adverse effects on human health, aquatic animals, and plants.

Detailed explanation-3: -E-waste contains numerous toxic chemicals including metals such as lead, cadmium, mercury, and nickel, and organic compounds such as flame retardants, chlorofluorocarbons, polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), and polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs).

Detailed explanation-4: -E-waste is hazardous because the components used to make devices such as laptops, cell phones, and televisions, contain metals and chemicals known to harm human health. Children, who are especially vulnerable to the effects of e-waste, often work, live, and play in or near e-waste recycling centers.

Detailed explanation-5: -Beryllium is sometimes used in circuit boards as an electrical connector and/or to insulate microprocessors. When improperly handled during disposal or recycling, beryllium dust can be released, which is known to cause severe lung disease and lung cancer.
