[Characteristics of Heavy Metal Pollution and Ecological Risk Evaluation of Indoor Dust from Urban and Rural Areas in Taiyuan City During the Heating Season].

The presence of heavy metals in indoor dust is a world-wide concern owing to its negative impact on humans. In this study, we collected indoor dust samples from urban and rural residential areas during the heating season in Taiyuan City. We then identified the concentrations of 11 heavy metals (Cd, Co, Cr, Pb, Mn, Ni, Cu, Zn, V, As, and Hg) using inductively coupled plasma-mass spectrometry.

[Influence of PM Pollution on Health Burden and Economic Loss in China].

Research on health and the economic losses caused by PM pollution nationwide is critical for pollution control planning. First, the spatiotemporal distribution of PM and exposure levels were simulated and analyzed using the air quality model (WRF-Chem) in China in 2016. Then, the health burden and economic loss caused by PM pollution were estimated using environmental health risk and environmental value assessment methods.

[Source and health risk assessment of heavy metals in ambient air PM10 from one coking plant].

To investigate the sources and health risk of heavy metals in ambient air PM10 from the coking plant, the PM10 in the air around one coking plant was collected in June 2012. Then the heavy metals concentrations in PM10 were tested by the microwave-ICP-MS method. Furthermore, the USEPA's human exposure assessment model was applied to preliminarily evaluate the human health risks of the heavy metals in air particulate matter.

[Effect of heavy metals exposure on neurobehavioral function in welders].

Objective: To explore the relationship between heavy metals exposure and neurobehavioral function impairment in welders.

Methods: The metals exposure in 82 welders and 51 operators were investigated with blood Pb, Cd and Mn via AAS, and the nervous impairment was evaluated with neurobehavioral core test battery (NCTB).

Results: Pb [(115.
