ESG Performance and Credit Risk: Evidence From Chinese Manufacturing Companies
International Journal of Finance &Economics, EarlyView.ABSTRACT This study investigates the effect of corporate environmental, social, and governance (ESG) performance on credit risk using a sample of manufacturing firms listed on China's Shanghai and Shenzhen A‐share markets from 2009 to 2021. Employing fixed effects, the generalised method of moments, and instrumental variable models, we find that ...

Land Degradation &Development, EarlyView.ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Isothermal Kinetic Mechanism of Coke Dissolving in Hot Metal
Metals, 2019 The carburization of molten iron is close to saturation in the blast furnace process, while that in the flash ironmaking process is uncertain because there is no pressure from solid charge and no carburization reactions occurring between the deadman and ...

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

PLANTS, PEOPLE, PLANET, EarlyView.Lead (Pb) accumulation in the human body poses serious health risks. As rice is the staple food in Sri Lanka, with a high per capita intake (114 kg), there is a significant risk of Pb transfer through rice consumption. This study evaluated exchangeable Pb concentrations in soils and produced Pb distribution maps.

PLANTS, PEOPLE, PLANET, EarlyView.Heavy metal contamination of soils poses a serious threat to ecosystem health and food security worldwide. This study investigated how native plants, such as Artemisia annua and Buddleja davidii, interact with soil microbes in Pb–Zn waste slag areas. We found that these plants stimulate microbes, which improve phosphorus availability and reduce metal ...
