Determinants of contractor's construction and demolition waste recycling intention in China: Integrating theory of planned behavior and norm activation model.

The abundant generation of construction and demolition waste (CDW) poses a threat to the sustainable development in China and recycling plays a vital role in complying with circular economy zero-waste goal. In this study, we first investigate the determinants of contractor's intention to recycle CDW by establishing an integrative model of the theory of planned behavior (TPB) and the norm activation model (NAM) with rational and moral considerations. Based on the questionnaire data of 210 valid responses, structural equation modeling is employed to test the proposed hypotheses and analyze the integrative structural model.

Studies on exposure status of inhabitants to water-arsenic valence states in areas with endemic arsenism in the Datong basin in Shanxi.

This study aimed to describe the distribution of water-arsenic (As) valence states and its relationship to areas with endemic arsenism in the Datong basin. Drinking water samples of patients with endemic arsenism and a control group were examined using hydride generation atomic fluorescence spectrometry (HG-AFS). We analyzed the data using SPSS10.
