Technology innovation has accelerated progress in Information and Communications
Technology (ICT), especially in the mobile phones sector. Concurrently, local,
national, and international governments are enforcing stricter regulations to
protect natural resources and human health. The paper attempts to address the
question: Have technological innovations and regulation development had a
positive impact on ecosystems and public health? We identified 36 waste mobile
phones (WMPs) manufactured between 2002 and 2013, assessed their metals
concentration, leachability, and potential impact on environment and human health
using digestion, Toxicity Characteristic Leaching Procedure (TCLP), and USEtox
model, respectively. The results highlight that regulations did not have
significant impact on total metal content, except some heavy metals, while
technology innovation recorded stronger impact. WMPs should be classified as
hazardous due to excessive lead content. Copper posed the most significant
ecotoxicity risk, and chromium showed the most significant risk for both
cancerous and non-cancerous diseases. Additionally, we demonstrated that WMPs
toxicity increased with technology innovation.
