  Title Case Study of Light Pollution in Urbanized Area of Slovakia Type Journal Article
  Year 2014 Publication Advanced Materials Research Abbreviated Journal Amr  
  Volume 899 Issue Pages 277-282  
  Keywords Slovakia; light pollution; light at night; public policy  
  Abstract This paper deals with the problem of light pollution and its potential impact on human body. Loss of darkness during the night has a negative effect on the environment, animals, plants and humans. Concerning humans, the light during the night can lead to desynchronization of circadian rhythms with subsequent lower production of sleeping hormone called melatonin. In addition to the negative impact on organisms, there is also economical effect of wastage of lighting during the night. Pollution caused by the occurrence of light during the night is relatively new term, which has been perceived very roughly so far. That is probably the reason, why Slovak legislation deals with this problem very roughly. Some limitation levels of illuminance of billboards were stated, but the legislation doesn ́t deal with the effect of the occurrence of higly influential light during the night on people at their homes.

  Title Model predicting discomfort glare caused by LED road lights Type Journal Article
  Year 2014 Publication Optics Express Abbreviated Journal Opt. Express  
  Volume 22 Issue 15 Pages 18056  
  Keywords LED; LED lighting; glare; road safety; traffic  
  Abstract To model discomfort glare from LED road lighting, the effect of four key variables on perceived glare was explored. These variables were: the average glare source luminance (Lg), the background luminance (Lb), the solid angle of the glare source from the perspective of the viewer; and the angle between the glare source and the line of sight. Based on these four variables 72 different light conditions were simulated in a scaled experimental set-up. Participants were requested to judge the perceived discomfort glare of these light conditions using the deBoer rating scale. All four variables and some of their interactions had indeed a significant effect on the deBoer rating. Based on these findings, we developed a model, and tested its general applicability in various verification experiments, including laboratory conditions as well as real road conditions. This verification proved the validity of the model with a correlation between measured and predicted values as high as 0.87 and a residual deviation of about 1 unit on the deBoer rating scale. These results filled the gap in estimating discomfort glare of LED road lighting and clarified similarities of and differences in discomfort glare between LED and traditional light sources.

  Title On Light Pollution, Passive Pleasures, and the Instrumental Value of Beauty Type Journal Article
  Year 2010 Publication Journal of Economic Issues Abbreviated Journal Journal of Economic Issues  
  Volume 44 Issue 1 Pages 71-88  
  Keywords ecomonics; skyglow  
  Abstract The night sky is a unique and exquisitely valuable cultural asset that is being lost to humanity. Light pollution obscures the heavens, interferes with wildlife, and wastes billions of dollars in energy annually. Light pollution can be easily mitigated, but unfortunately, it has gone largely unnoticed as a preventable environmental problem. This paper examines light pollution as well as the value of the night sky. The paper focuses on society's disregard for the loss of a cultural asset that has been a part of art, science, and culture for as long as these things have existed. It argues that the blame lies largely in an inability to articulate adequately the value of natural beauty. It is further argued that such beauty has instrumental value, and the explicit recognition of this value is an important step toward preserving the night sky and other objects of natural beauty.

  Title Artificial light as a disturbance to light-naïve streams Type Journal Article
  Year 2014 Publication Freshwater Biology Abbreviated Journal Freshw Biol  
  Volume 59 Issue 11 Pages 2235–2244  
  Keywords cutthroat trout; drift; invertebrates; light pollution; urbanization; *Fishes; Oncorhynchus clarkii; British Columbia  
  Abstract Summary

Artificial light at night is prevalent in human-dominated landscapes, and streams in these landscapes can be expected to be affected by artificial lights. We hypothesised that artificial light at night would reduce the activity of aquatic insects, resulting in reduced drift rates, lower fish growth rates and lower leaf litter decomposition rates.

We tested these hypotheses by installing street lights to reaches in four forested, natural streams of coastal British Columbia each paired with a control reach. Cutthroat trout (Oncorhynchus clarkii) are the top predators in these streams and feed mostly on terrestrial and drifting aquatic invertebrates.

We found that the night-time drift of aquatic invertebrates in lit reaches was ˜50% of the drift in dark reaches. However, the density of emerging aquatic insects, the density of insects falling into reaches, leaf litter decomposition rate and the number and growth rate of trout caught were not significantly different between the dark and experimentally lit reaches.

We conclude that, while short-term exposure to artificial light during the summer changes invertebrate behaviour, it does not significantly alter other trophic levels in forested headwater streams. Our results suggest that low levels of artificial light do not strongly influence stream ecosystems, but future research should determine whether this is true for all seasons and longer-term exposure to light.
