Experts from the Intermediate Technology Development Group, a research organization, claim that people who are too poor to afford cleaner fuels could still reduce their exposure to dangerous fumes by as much as 80 percent by using well - designed chimney stoves or smoke hoods.
Uurimisorganisatsiooni Intermediate Technology Development Group ekspertide väitel saaksid need, kes on puhtamate põletusainete muretsemiseks liiga vaesed, korraliku korstnaga varustatud pliiti või suitsulõõri kasutades vähendada ohtlike suitsugaaside hulka isegi 80 protsendi võrra.
