Objectives Environmental pollution is a significant global issue. Both objective (scientifically measured) environmental pollution and perceived levels of pollution are important predictors of self-reported health. The purpose of this study was to compare the associations between perceived environmental pollution and health in China, Japan, and South Korea. Methods Data were obtained from the...
Background: Electromagnetic fields interact with human tissues and may have adverse effects on fertility and reproduction. During the last decades there has been a growing concern on the effects of electromagnetic radiations on biological systems in general. Radiation risks from electromagnetic fields generated by processes such as reduced fertility and a significant decrease in implantation ra...
The main goal of this study was to evaluate the possible effect of whole-body magnetic field (MF) exposure on the variations of corticosterone, Free-T3, Free-T4 and malonyl dialdehyde in plasma in 48 adult white New Zealand male rabbits. Animals were divided into six groups namely, C1 (normal diet, not exposed), C2 (normal diet, sham exposed), T1 (normal diet, exposed to electromagnetic field),...
OBJECTIVES Air pollution contributes to mortality and morbidity. We estimated the impact of outdoor air pollution on public health in Seoul metropolitan area, Korea. Attributable cases of morbidity and mortality were estimated. METHODS Epidemiology-based exposure-response functions for a 10 μg/m3 increase in particulate matter (PM2.5 and PM10) were used to quantify the effects of air pollutio...
Abrupt environmental pollution accidents cause considerable damage worldwide to the ecological environment, human health, and property. The concept of acceptable risk aims to answer whether or not a given environmental pollution risk exceeds a societally determined criterion. This paper presents a case study on acceptable environmental pollution risk conducted through a questionnaire survey car...
Background and Objective: Diabetes influences the normal function of the pituitary-thyroid axis. According to the antidiabetic and antioxidant effects of curcumin and the different effects of electromagnetic fields on animal cells, this study was done to evaluate the effect of curcumin and weak low frequency electromagnetic fields on thyroid hormone serum levels in male diabetic rats. Materi...
Abstract Background and Objective: Omega-3s are considered essential fatty acids that cannot be synthesized by human body and should be obtained from foodstuff. This study aimed at evaluating the beneficial effect of Omega-3s ,exposed in Electromagnetic Field (EMF), on sexual behavior ,Serum total testosterone level, malondialdehyde (MDA) level and total antioxidant capacity(TAC) in male...
The objective of this paper is to survey the results of studies on the biological effects of electromagnetic fields on fish. First, the basic concepts of electromagnetism and electromagnetic spectrum and the importance of studying it in the case of fish are discussed. Then a summary of the results obtained on the effects of extremely low frequency electromagnetic fields (ELF-EMFs) and radiofreq...
Using China’s provincial economic and pollution data from 1992 to 2008, we employ data envelope analysis (DEA) and econometric analyses to explicitly estimate technical efficiency and examine the role of technical efficiency, pollution control instruments (pollution levy and pollution quantity control), and prices of production inputs on pollution intensity. We find that an increase of labor wa...
