Title Effects of artificial light at night on human health: A literature review of observational and experimental studies applied to exposure assessment Type Journal Article
Year 2015 Publication Chronobiology International Abbreviated Journal Chronobiol. Int.
Volume (down) 32 Issue 9 Pages 1294-1310
Keywords Artificial light at night; breast cancer; circadian rhythm; light exposure; light pollution
Abstract It has frequently been reported that exposure to artificial light at night (ALAN) may cause negative health effects, such as breast cancer, circadian phase disruption and sleep disorders. Here, we reviewed the literature assessing the effects of human exposure to ALAN in order to list the health effects of various aspects of ALAN. Several electronic databases were searched for articles, published through August 2014, related to assessing the effects of exposure to ALAN on human health; these also included the details of experiments on such exposure. A total of 85 articles were included in the review. Several observational studies showed that outdoor ALAN levels are a risk factor for breast cancer and reported that indoor light intensity and individual lighting habits were relevant to this risk. Exposure to artificial bright light during the nighttime suppresses melatonin secretion, increases sleep onset latency (SOL) and increases alertness. Circadian misalignment caused by chronic ALAN exposure may have negative effects on the psychological, cardiovascular and/or metabolic functions. ALAN also causes circadian phase disruption, which increases with longer duration of exposure and with exposure later in the evening. It has also been reported that shorter wavelengths of light preferentially disturb melatonin secretion and cause circadian phase shifts, even if the light is not bright. This literature review may be helpful to understand the health effects of ALAN exposure and suggests that it is necessary to consider various characteristics of artificial light, beyond mere intensity.

Title Analysis on Luminance of Outdoor Signboards of Commercial Areas in Seoul at Night Considering Light Pollution Type Journal Article
Year 2015 Publication Journal of The Korean Society of Living Environment System Abbreviated Journal J. Korean Soc. Living Environ. Sys
Volume (down) 22 Issue 4 Pages 583-595-589
Keywords Lighting; Light pollution; Commercial areas; Night-time lighting; Outdoor Signboards; Luminance; outdoor lighting; artificial light at night; signs; LED signs; LED billboards
Abstract As the city is commercialized, the number of stores is increased and it also makes outdoor billboards’ number increased accordingly. And signboards on the street make pedestrians unpleasant, making light pollution by light reflection. In this study, we measured the luminance to target the outdoor signboards of commercial area in Seoul. On the basis of the obtained results, the External system showed high luminance values, and the luminance values of Letter-type system were lower. Furthermore, the measured value at the midnight time was higher, and we considered that the more floating population bring about the high luminance value of the External system. The signboards of External system should be avoided, the Letter-type system should be recommended.

Title Light Pollution Changes the Toxicological Effects of Cadmium on Microbial Community Structure and Function Associated with Leaf Litter Decomposition Type Journal Article
Year 2020 Publication International Journal of Molecular Sciences Abbreviated Journal Int J Mol Sci
Volume (down) 21 Issue 2 Pages
Keywords Plants; Illumina Sequencing; artificial light at night; cadmium pollution; extracellular enzyme activities; litter decomposition; microbial biodiversity
Abstract Artificial light at night (ALAN/A) can not only alter the behavior and communication of biological organisms, it can also interact with other stressors. Despite its widespread use and the numerous potential ecological effects, little is known about the impact of ALAN on plant litter decomposition under cadmium (Cd) pollution in aquatic ecosystems. In an indoor microcosm experiment, we tested single and combined effects of ALAN and Cd on the activities and community structure of fungi associated with plant litter. The results showed that ALAN and/or Cd can change both water and leaf litter characteristics. ALAN exposure not only altered fungal community structure and their correlations, but also increased the activities of alkaline phosphatase, beta-glucosidase, and cellobiohydrolase. The leaf litter decomposition rate was 71% higher in the A-Cd treatment than that in the N-Cd treatment, indicating that the presence of ALAN weakened the negative impact of Cd on leaf litter decomposition. These results suggested that ALAN exposure mitigated the negative effect of Cd on leaf litter decomposition, contributing to the duel effect of ALAN on leaf litter decomposition. Overall, the results expand our understanding of ALAN on the environment and highlight the contribution of ALAN to Cd toxicity in aquatic ecosystems.

Title Temporal changes in artificial light exposure of marine turtle nesting areas Type Journal Article
Year 2013 Publication Global Change Biology Abbreviated Journal Glob Chang Biol
Volume (down) 20 Issue 8 Pages 2437-2449
Keywords GIS analysis; artificial light; conservation planning; marine turtles; population resilience; temporal change
Abstract Artificial light at night poses a significant threat to multiple taxa across the globe. In coastal regions, artificial lighting close to marine turtle nesting beaches is disruptive to their breeding success. Prioritizing effective management of light pollution requires an understanding of how the light exposure of nesting areas changes over time in response to changing temporal and spatial distributions of coastal development. We analyzed multitemporal, satellite night-light data, in combination with linear mixed model analysis, to determine broadscale changes in artificial light exposure at Australian marine turtle nesting areas between 1993 and 2010. We found seven marine turtle management units (MU), from five species, have experienced significant increases in light exposure over time, with flatback turtles nesting in east Australia experiencing the fastest increases. The remaining 12 MUs showed no significant change in light exposure. Unchanging MUs included those previously identified as having high exposure to light pollution (located in western Australia and southern Queensland), indicating that turtles in these areas have been potentially exposed to high light levels since at least the early nineties. At a finer geographic scale (within-MU), nine MUs contained nesting areas with significant increases in light exposure. These nesting areas predominantly occurred close to heavily industrialized coastal areas, thus emphasizing the importance of rigorous light management in industry. Within all MUs, nesting areas existed where light levels were extremely low and/or had not significantly increased since 1993. With continued coastal development, nesting females may shift to these darker/unchanging 'buffer' areas in the future. This is valuable information that informs our understanding of the capacity and resilience of marine turtles faced with coastal development: an understanding that is essential for effective marine turtle conservation.

Title Coastal light pollution and marine turtles: assessing the magnitude of the problem Type Journal Article
Year 2012 Publication Endangered Species Research Abbreviated Journal Endang. Species. Res.
Volume (down) 19 Issue 1 Pages 85-98
Keywords Artificial light; Orientation; Coastal development; GIS analysis; Vulnerability assessment; turtles; reptiles; animals; marine turtles; Australia; Queensland
Abstract Globally significant numbers of marine turtles nest on Australian beaches; however, the human population of Australia is also heavily concentrated around coastal areas. Coastal development brings with it increases in artificial light. Since turtles are vulnerable to disorientation from artificial light adjacent to nesting areas, the mitigation of disruption caused by light pollution has become an important component of marine turtle conservation strategies in Australia. However, marine turtles are faced with a multitude of anthropogenic threats and managers need to prioritise impacts to ensure limited conservation resources can result in adequate protection of turtles. Knowledge of the extent to which nesting areas may be vulnerable to light pollution is essential to guide management strategies. We use geographical information system analysis to over-lay turtle nesting data onto night-time lights data produced by the NOAA National Geophysical Data Center, to assess the proportion of marine turtles in Australia potentially at risk from light pollution. We also identify the Australian nesting sites which may face the greatest threat from artificial light. Our assessment indicates that the majority of nesting turtles appear to be at low risk, but population management units in Western Australia and Queensland are vulnerable to light pollution. The risk to turtles from light generated by industrial developments appears significantly higher than at any other location. Consequently, managers of turtle management units in regions of proposed or on-going industrial development should anticipate potentially disrupted turtle behaviour due to light pollution. Our methodology will be useful to managers of turtles elsewhere.
