Original text from Osibanjo and Nnorom $(2007,$ p$.498)$:

The actual operation of several end$-$of$-$life processes for e$-$waste such as landfill, incineration with MSW and mechanical recycling results in emissions of heavy metals and organic pollutants to air, water, soil and residual potentially hazardous waste. E$-$waste contains more than $1000$ different substances, many of which are highly toxic $($Widmer et al$.2005).$

Student text:

The fact that many ways of managing e$-$waste result in emissions and residues $($Osibanjo & Nnorom $2007,$ p$.498)$ is of concern, particularly because electronic products are constituted of a significant number of very toxic materials $($Widmer et al$.,$ cited in Osibanjo & Nnorom $2007,$ p$.498).$
