Nigeria is becoming a digital dump, the recipient of vast numbers of broken gadgets from the West that can leak dangerous substances into water supplies and create cancer-causing particles when burnt, a toxic waste watchdog [Basel Action Network] said on Thursday..."We are still trying to quantify the magnitude of the electronic waste we have in Nigeria and the components that are toxic," Dada [Oludayo Dada of the pollution control unit at Nigeria's environment ministry] told IRIN, adding that the government would need to update its laws to criminalise the import of such products.
