Read the passage below carefully.
Despite the rapid proliferation of electronic devices across urban Nigeria, informal electronic waste recycling practices continue to pose severe environmental and public health hazards. Unregulated recyclers frequently employ rudimentary techniques��such as open burning of printed circuit boards and acid leaching—to extract precious metals like gold and copper. While these methods yield immediate subsistence income for informal workers, they simultaneously release toxic heavy metals, including lead and mercury, into municipal soil and drainage systems. Environmental regulatory agencies advocate for formalizing the sector through subsidized collection hubs and specialized safety training. However, transition efforts remain stalled primarily because informal collectors resist joining regulated networks that impose operational compliance fees and reduce their profit margins.
Which of the following statements best summarizes the central message of the passage?
- AUnregulated recyclers in urban Nigeria extract valuable metals such as gold and copper by burning printed circuit boards and using acid leaching techniques.
- BFormalizing the e-waste recycling sector through subsidized collection hubs will completely eliminate heavy metal pollution and guarantee profitability for workers.
- Informal electronic waste recycling provides immediate subsistence income despite causing severe environmental contamination, but efforts to formalize the sector are stalled by workers' reluctance to lower their profit margins.Cevap
- DGovernment regulatory agencies have successfully banned informal recyclers from using hazardous acid leaching methods across municipal drainage systems.
