摘要

Abstract

In the kitchens in severely cold areas of China during winter

an effective balance has not been achieved between maintaining the indoor temperature and ensuring the air quality. Compared with other regions

the PM

2.5

pollution situation is more serious. In this paper

the PM

2.5

concentrations in 62 typical kitchens during the cooking and non-cooking processes were tested

and questionnaire surveys were conducted among 288 households. The health impacts and economic losses caused by cooking PM

2.5

in winter in Liaoning Province were quantitatively evaluated. The results indicated that the PM

2.5

concentration in the kitchen during the cooking process in Liaoning region is 0.438 mg/m

which is 0.295 mg/m

higher than that in Shanghai region. The highest PM

2.5

concentration (1.102 mg/m

) is generated when cooking four dishes

and it has the greatest impact on health and economy. In 2021

the contributions of being exposed to the PM

2.5

environment in the kitchen to the daily all-cause deaths

hospitalizations

and outpatient visits for cardiovascular and respiratory diseases were more than 3.78

15.50 and 3201.15 respectively. The indirect total economic loss caused by cooking PM

2.5

in Liaoning province was more than 844.53 × 10⁴ RMB. While meeting the temper

ature requirements

it is urgent to solve the problem of the high concentration of PM

2.5

in kitchens in cold areas to reduce the impact of the kitchen environment on health and economy.
