Particulate matter from cooking oil fumes (COF) has
great potential adverse effects on human health. In this report, to study the
effect of kinds of Chinese ordinary family cooking dishes and air flow rates of
range hood on the cook’s health risk, numerical simulations are executed to
obtain the exposure concentration of PM2.5 from COF. Compared with
the types of cooking dishes, the air flow rate of range hood has a more
significant effect on PM2.5 capture efficiency. On the contrary, the
health risks of family cook exposed to PM2.5 from COF are more
likely to be affected by types of cooking dishes. The results showed that the
health risk value all exceed the acceptable limit of 10-6,
and thus of health concerns. The recommended frequencies of the three
dishes were proposed. |
