[Impact of different temperatures and ambient PM2.5 on the cytotoxicity and cytophagocytic function of alveolar macrophages of rat].

Objective: To investigate the interactive effects of different temperatures and ambient PM2.5 on the rat alveolar macrophages.

Methods: The rat alveolar macrophages were collected.

Improving Knowledge about Children's Environmental Health in Northwest China.

The main purpose of this study was to identify policy maker opinions and attitudes towards children's environmental health (CEH), potential barriers to child-specific protective legislation and implementation in northwest China, and evaluate knowledge and attitudes about CEH before and after an educational conference. We conducted seventy-two interviews with regional officials, researchers and non-governmental organization representatives from five provinces, and surveyed participants (forty-seven) before and after an educational conference in northwest China about CEH. Interviews identified general consensus among participants of the adverse effects of air pollution on children, yet few participants knew of policies to protect them.

Rat lung response to PM2.5 exposure under different cold stresses.

Ambient particulate matters and temperature were reported to have additive effects over the respiratory disease hospital admissions and deaths. The purpose of this study is to discuss the interactive pulmonary toxicities of cold stress and fine particulate matter (PM2.5) exposure by estimating inflammation and oxidative stress responses.
