Please address this question to Prof Philip Lloyd who is subscribed to this list. He is a professor of chemical engineering and has a stove testing lab. He may have good ideas on how to design a test method. </div>

<div dir="ltr">Dear stovers,
<div><br>
</div>
<div>We are testing rice straw pellet in a small TLUD gasifier in Vietnam. </div>
<div>There's a concern raised during our test that the toxic gases and Polycyclic aromatic hydrocarbons (PAHs) emitted from the gasification process of rice straw pellet may affect the human health. <br>
</div>
<div>Especially the toxic gases may comes from the left-over pesticide inside rice straw under high gasification temperature.</div>
<div><br>
</div>
<div>Any suggestion for further testing and/or scientific evidence relating to this are highly appreciated !</div>
<div><br>
</div>
<div>Thanks</div>
