Particulate and particulate-bound mercury concentrations and size distributions as related to seasonal variations during peak demand/non-peak demand periods. J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-09-16 Guor-Cheng Fang,Chao-Lang Kao,Yuan-Jie Zhuang,Gui-Ren Liang
Abstract The particulate size distributions of aerosol pollutants (particulates and Hg(p)) at a mixed site were measured and their seasonal variations identified. Atmospheric particulates and the Hg(p) mass median diameter (m.m.d.) were obtained. Hg(p) concentrations increased by approximately 20% during the peak demand period for all particle sizes (18, 10, 2.5, 1 and 0.3 μm). The mean percentage

Ambient air pollution exposure association with diabetes prevalence and glycosylated hemoglobin (HbA1c) levels in China. Cross-sectional analysis from the WHO study of AGEing and adult health wave 1. J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-07-02 Mona Elbarbary,Trenton Honda,Geoffrey Morgan,Patrick Kelly,Yuming Guo,Joel Negin
Over the past decades, air pollution has become one of the critical environmental health issues in China. The present study aimed to evaluate links between ambient air pollution and the prevalence of type 2 diabetes mellitus (T2DM) and the levels of glycosylated hemoglobin (HbA1c). A multilevel linear and logistic regression was used to assess these associations among 7,770 participants aged ≥50 years

Skin transferability of phthalic acid ester plasticizers and other plasticizers using model polyvinyl chloride sheets. J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-08-04 Tsuyoshi Kawakami,Kazuo Isama,Hideto Jinno
The transferability of phthalic acid esters (PAEs) and other plasticizers, from model polyvinyl chloride (PVC) sheets to the skin of 11 subjects was assessed by measuring the amount of substance transferred using PVC sheets containing PAEs and alternative plasticizers of different types and contents. For all subjects, the transferred amount, from sheets containing 28 wt% PAE or from mixed sheets containing

Exposure to organic solvents and hepatotoxicity. J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-06-30 Cristiano Brauner,Dvora Joveleviths,Mário R Álvares-da-Silva,Norma Marroni,Silvia Bona,Elizângela Schemitt,Raissa Nardi
The purpose of this study was to identify the long-term effect of chemical exposure on the liver. Laboratory tests included alanine aminotransferase (ALT) dosage and oxidative stress tests, such as thiobarbituric acid reactive substances in plasma and superoxide dismutase (SOD) and glutathione S-transferase analysis in erythrocytes. The cross-sectional study comprised 70 workers, 30 of them exposed

Radiation-induced synthesis of tween 80 stabilized silver nanoparticles for antibacterial applications. J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-07-02 Mohamad Bekhit,Mohamed N Abu El-Naga,Rehab Sokary,Ramy Amer Fahim,Naeem M El-Sawy
Recently, Silver nanoparticles (AgNPs) have become widely applied nanomaterial in human contacting areas such as cosmetics, food and medicine due to their antibacterial property. On the other hand, surfactants are essential ingredient of several industrial and consumer formulations. Based on these important applications, the current research was aimed to carry out the synthesis and characterization

The removal efficiency of lead from contaminated soil: modeling of cations and anions migration during the electrokinetic treatment. J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-07-02 Ourida Ait Ahmed
The effect of the presence of minerals in natural soil polluted with lead (II) was investigated to verify the efficiency of the electrokinetic remediation method. Natural soil “Sebkha of Oran” containing high calcite minerals and characterized by high salinity was used in experimental studies. This study investigates the effects of alkaline soil pH conditions on the transport and removal of lead by

Feasibility of using plastic wastes as constructed wetland substrates and potential for pharmaceuticals and personal care products removal J. Environ. Sci. Health Part A (IF 1.724) Pub Date : 2020-07-08 Xiaofei Chen; Xiaolong Huang; Kai Zhang; Chenxi Wu
Each year, large amounts of plastic waste are generated and must be appropriately disposed. In this work, we studied the feasibility of using plastics as wetland substrates as an alternative plastic waste disposal method and the ability of the constructed wetland to remove pharmaceuticals and personal care products (PPCPs) from contaminated water. Wetland microcosms were constructed using polycarbonate
