In this study, we analyzed hydroxylated polychlorinated biphenyls (OH-PCBs) in urine of both PCB transport workers and PCB researchers. A method to monitor OH-PCB in urine was developed. Urine was solid-phase extracted with 0.1% ammonia/ methanol (v/v) and glucuronic acid/sulfate conjugates and then decomposed using β-glucuronidase/arylsulfatase. After alkaline digestion/derivatization, the concen...... hiện toàn bộ
How does renewable energy, newborn birth rates, industrialization, and economic growth affect environmental quality? New evidence from 90 Belt and Road countriesSpringer Science and Business Media LLC - Tập 30 - Trang 104148-104168 - 2023

Reducing carbon emissions is a critical approach for attaining global environmental sustainability and combating climate change. To investigate how energy, population, industry, and economic structure affect environmental quality. This study collects panel data for 90 Belt and Road (B&R) nations from 1995 to 2021. For the first time, the nonlinear dynamic impacts of renewable energy, newborn birth...... hiện toàn bộ
Does low-carbon city pilot affect the enterprise competitiveness in China? Based on a staggered difference-in-difference modelSpringer Science and Business Media LLC - Tập 30 - Trang 37233-37247 - 2022

China has recently instituted the low-carbon city pilot (LCCP) policy in target areas to control its greenhouse gas emissions. Studies examining those environmental regulations have not focused on how they affect enterprise competitiveness, especially emphasizing the LCCP’s dynamic effect. Here, we use the quasi-experimental opportunities of the LCCP policy along with a staggered difference-in-dif...... hiện toàn bộ

Exposure to harmful levels of ultraviolet-B radiation (UVB), a component of solar radiation, has been suggested as a potential cause of amphibian declines. We measured solar radiation (UVB, ultraviolet-A, and visible) wavebands in breeding ponds of Bufo boreas (boreal toad, a montane species that has undergone severe population declines) and Bufo woodhousii (Woodhouse’s toad, a plains toad that ha...... hiện toàn bộ
Mechanistic insights to lactic and formic acid toxicity on benthic oligochaete worm Tubifex tubifexSpringer Science and Business Media LLC - Tập 29 - Trang 87319-87333 - 2022

Lactic and formic acid are two commonly found monocarboxylic organic acids. Lactic acid is discharged into the water bodies as acidic industrial effluent from the food, cosmetic, chemical, and pharmaceutical industries, whereas formic acid is discharged from various paper, leather tanning, and textile processing industries. The present study investigated the toxicity of both organic acids upon the...... hiện toàn bộ
