Sri Lanka kidney disease blamed on farm chemicals

But if arsenic and cadmium are to blame, where are they coming from?

The new study blames farm chemicals, which are cheap in Sri Lanka, thanks to government subsidies, and often overused.

Cadmium is found in some fertilisers. Arsenic is an active ingredient in some pesticides.

Companies that import and sell pesticides and herbicides contest the government's conclusion. They point out that the government and WHO have not yet released their full study.
