Effects of magnetic hydroxyapatite loaded biochar on Cd removal and passivation in paddy soil and its accumulation in rice: a 2-year field study.

Stabilized cadmium (Cd) was extremely easy to be re-released into the environment. The study was aim to explore the Cd removal efficiency and passivation in paddy soil by magnetic hydroxyapatite loaded biochar (MHBC), and to investigate the effect of MHBC on Cd accumulation and yield of rice with low Cd accumulation cultivar named ZhuLiangYou189 (ZLY189) and conventional cultivar named ZhuLiangYou929 (ZLY929) in 2-year field trials. These results shown that MHBC under the high dosage of 25.

Reduction of cadmium bioavailability in paddy soil and its accumulation in brown rice by FeCl washing combined with biochar: A field study.

Cadmium (Cd) removal from paddy soil to reduce Cd accumulation in brown rice is essential for agroecology, food safety, and human health. In this study, we demonstrate that ferric chloride (FeCl) washing combined with biochar treatment efficiently remediates Cd-contaminated paddy soil in field trials. Our results showed that 30.

Insights into deep decline of As(III) leachability induced by As(III) partial oxidation during lime stabilization of As-Ca sludge.

The enhancing effect of As(III) oxidation on As stabilization by lime is routinely attributed to the lower solubility of Ca arsenates than Ca arsenites. However, this routine explanation is insufficient for the scenario of As(III) partial oxidation, in which Ca arsenites still predominate As leachability due to the relatively high solubility. In this study, an As-Ca sludge with a high As(III) content (96 g/kg, 55% of the As(tot)) was treated by oxidant-lime to clarify the positive effect of As(III) partial oxidation.

Effect of family "upward" intergenerational support on the health of rural elderly in China: Evidence from Chinese Longitudinal Healthy Longevity Survey.

As health challenging rural elderly in an aging population, more attention is being paid on impact of family intergenerational support on the health of the elderly. This paper investigates the effects of children's intergenerational economic support and non-economic support on physical, mental, and functional health of rural elderly in China in the mean while. This paper applies the 2014 Chinese Longitudinal Healthy Longevity Survey (CLHLS), in particular, applying exploratory factor analysis to ascertain latent variables and Structural Equation Model (SEM), and analyzes the impacts of "Upward" intergenerational support on health of rural elderly.

Effect of medical insurance and family financial risk on healthcare utilisation by patients with chronic diseases in China: a cross-sectional study.

Objective: To assess the joint cumulative effects of medical insurance and family health financial risk on healthcare utilisation among patients with chronic conditions in China.

Design: A nationwide population-based case-control study with multinomial logistic regression was conducted and used to estimate the ORs of healthcare utilisation against type of medical insurance and family health financial risk using the Anderson model as a theoretical framework.

Setting: China Family Panel Studies (CFPS) database.
