Commentary on the utility of the National Toxicology Program study on cell phone radiofrequency radiation data for assessing human health risks despite unfounded criticisms aimed at minimizing the findings of adverse health effects

The purpose of the study was to establish hygienic procedures for reducing health risks of the population living and working near oil extraction sites. Based on the results obtained, we evaluated the quality of environmental settings in the oil extraction areas, studied working conditions of oil workers, and assessed public human health and occupational risks of the oil extraction industry. Oil extraction enterprises have been shown to be major sources of environmental and workplace pollution and to create a negative background causing adverse health effects.

Health And Well Being

The frequency of simultaneous or consecutive heatwaves, droughts and wildfires is increasing. Compound dry-hot extreme events, defined as a mix of concurrent or sequential occurrence of heatwaves, droughts and fires, contribute to risks and impacts to both society and the environment. Compound dry-hot extreme events already pose serious impacts on human health and well-being, and these impacts are expected to increase in the future. The purpose of this report is to discuss the need for improved individual and community preparedness and response to compound dry-hot extreme events, and to highlight the benefits such improvements would bring. In particular, the development and implementation of compound dry-hot extreme events action plans is essential for reducing the adverse health effects of current and future compound dry-hot extreme events.

Background and Purpose:The digital textbook (DT) is an appealing new educational medium. The positive effects of DT use include stimulation of interest in learning and stimulation of motivation to learn. Few studies have examined the awareness of classroom-based educational experts about the adverse health outcomes of DT use. The objective of this study was to understand the perspectives of elementary schoolteachers regarding the effects of DT use on students’ health.Methods:The recommended method of focus group discussions was used to clarify teachers’ individual and shared views about this topic. The study design included three discussions with three different groups of teachers.Results:The results indicated that the critical health issues identified by the schoolteachers were potential risks to physical health, risks to psychological health, and environmental health risks in the classroom.Implications for Practice:Awareness and evaluation of adverse health effects for DT users is an important first step for effective DT implementation in our schools. This study provided fundamental data and results that can be used to understand the effects of DT use on student health and to suggest guidelines to predict and prevent adverse health effects in the users of this technology.

Pediatric Populations

Currently, there is a paucity of studies evaluating the adverse health effects of benzene exposure in children or clinical findings of those children who have been exposed. However, emerging studies show that benzene exposure can cause deleterious health effects in children. The objective of this study was to evaluate and summarize published studies on the adverse health effects of benzene exposure in children. More than 77 articles were examined and only the articles that dealt with adverse health effects on pediatric populations were included in the study. The evaluation of those studies provided current understanding of the health effects of benzene exposure in children. Findings from the currently available studies reveal that benzene exposure is associated with abnormalities in hematologic, hepatic, respiratory, and pulmonary functions in children. Published studies clearly support the need for further assessment of the potential adverse effects of benzene exposure in children, and clinical and laboratory findings of these children.

Adverse Health

Odor control is a frequent issue at facilities that process municipal solid waste. Even waste-to-energy facilities, which are typically operated under “negative pressure,” may be less than 100% effective at preventing the occasional release of odorous emissions. When odors travel off-property to nearby residents and businesses, the tangible exposure often elicits concerns about the specific chemicals responsible for the odor and the potential for the emissions to affect public health. However, because the gaseous compounds that may lead to objectionable off-site odors are generally different than those that might result in adverse health effects, conditions of odor and risk are not as closely linked as is sometimes assumed. While odors can be assessed through personal observations, the assessment of risk requires detailed knowledge of the composition of the emitted gases. The gas produced from the aerobic decay of municipal solid waste contains a different mix of chemicals that are not as well characterized than gas produced from the anaerobic decay of waste in a landfill (which has been analyzed by the U.S. EPA and others). Air samples were recently collected from the tipping floor of a waste-to-energy facility, analyzed for chemical composition, and evaluated for their potential to lead to off-site health risks. The composition of the gas was found to be similar to published data from other MSW handling facilities, and includes both basic hydrocarbons and some EPA-designated Hazardous Air Pollutants. Thirty-two different volatile organic compounds were detected. Ethanol was found to be the most prevalent compound, almost two orders of magnitude greater in concentration than other chemicals. Additional compounds identified in the gas samples include (in order of abundance) methyl ethyl ketone, acetone, sec-butanol, isopentane, acetaldehyde, butane, isopropyl alcohol, limonene, and 1-propanol. A case-specific atmospheric dispersion of the gases was modeled to predict off-site concentrations much smaller than levels known to cause adverse health effects. Based on odor characteristics of the gas, generically extrapolating the study to other settings suggests that short-term odorous conditions due to MSW management facilities (waste-to-energy facilities, transfer stations, etc.) do not typically correspond to significant long-term health risks.

Bacterial Endotoxins

Exposure to cyanobacterial water blooms has been associated with various kinds of adverse health effects. In addition to cyanobacteria and their toxins, the bacteria associated with cyanobacteria could also be the etiological agents. We isolated Aeromonas strains (n = 176) from water samples (n = 38) taken from sites where cyanobacteria were suspected to have caused human health symptoms, of which fever and gastrointestinal symptoms were the most common. The isolates were screened by PCR for six virulence gene types (12 genes). The majority (90%) of the strains contained at least one of the virulence genes. Most common amplification products were those of genes (act/aerA/hlyA) that encode cytotoxic enterotoxin and haemolytic products. The genes encoding cytotonic enterotoxins (ast and alt), phospholipase (lip/pla/lipH3/alp-1), elastase (ahyB) and flagellin subunits (flaA/flaB) were also present in 5–37% of the Aeromonas strains. Analysed toxins (cyanobacterial hepatotoxins and neurotoxins, and bacterial endotoxins) were not detectable or were present in only low concentrations in the majority of the samples. The results indicated that the toxins were unlikely to be the main cause of the reported adverse health effects, whereas more attention should be paid to bacteria associated with cyanobacteria as a source of health effects.
