Title Artificial Light Pollution at Night: A Risk for Normal Circadian Rhythm and Physiological Functions in Humans Type Journal Article
Year 2019 Publication Current Environmental Engineering Abbreviated Journal Cee
Volume 6 Issue 2 Pages 111-125
Keywords Review; Human Health
Abstract From the past three to four decades, ecologists and scientists have exhaustively studied the effect of increased artificial light pollution at night on the ecological and physiological behavior of mammals. The Suprachiasmatic Nuclei (SCN) or master clock in the brain of mammals including humans synchronizes the physiological functions with the light: dark cycle. The prolongation of light period in the light: dark cycle disrupts the circadian rhythm of mammals causing several negative or modified physiological consequences. Changed physiological level of melatonin, an important endocrine hormone, had been identified as an important factor causing different consequences such as cancer, diabetes mellitus, metabolic disturbances, oxidative stress, and depression. The presence of artificial light at night is the demand of the era but thoughts must be given to the prevention of consequences due to artificial light pollution and ‘how much is needed’. The review paper discusses the effect of artificial light pollution on the biological clock of humans and associated negative physiological consequences. Further, the paper also briefly discusses the economics of light pollution and measures needed to prevent physiological disorders in humans.

Title Light-at-night exposure affects brain development through pineal allopregnanolone-dependent mechanisms Type Journal Article
Year 2019 Publication ELife Abbreviated Journal Elife
Volume 8 Issue Pages
Keywords Animals; chicken; neuroscience
Abstract The molecular mechanisms by which environmental light conditions affect cerebellar development are incompletely understood. We showed that circadian disruption by light-at-night induced Purkinje cell death through pineal allopregnanolone (ALLO) activity during early life in chicks. Light-at-night caused the loss of diurnal variation of pineal ALLO synthesis during early life and led to cerebellar Purkinje cell death, which was suppressed by a daily injection of ALLO. The loss of diurnal variation of pineal ALLO synthesis induced not only reduction in pituitary adenylate cyclase-activating polypeptide (PACAP), a neuroprotective hormone, but also transcriptional repression of the cerebellar Adcyap1 gene that produces PACAP, with subsequent Purkinje cell death. Taken together, pineal ALLO mediated the effect of light on early cerebellar development in chicks.

Title Artificial light sources as light pollutant of humans melatonin suppression Type Journal Article
Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL
Volume 11 Issue 3 Pages 78
Keywords Human Health
Abstract Blue light emitted by LEDs might influence thenatural biological rhythm of a human being, whichcan beconsidered as environment pollution.In this paper the effect of the latest commercially available LEDs on melatonin suppression index (MSI) was analyzed. The research was based on spectral power distributionof a given LED(SPD) and melatonin suppression functionin reference to melatonin suppression under daylight (illuminant D65). The resultsof calculations show astrong correlation between CCT and MSI;however,MSI factor might vary for different LEDs with the same CCT.

Title Outdoor Areas Lighting with LEDs – the Competition Between Scotopic Efficacy and Light Pollution Type Journal Article
Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL
Volume 11 Issue 3 Pages 75
Keywords Skyglow
Abstract In this paper the effect of spectral power distribution SPD

of typical outdoor LED lamps on star visibility index SVI was analyzed.

For those lamps the nearest color temperature CCT [K] and scotopic

efficacy lm/W] data are also provided. The SVI has been defined as a

ratio of its scotopic flux to scotopic flux created by full moon light. The

calculations show that there is a strong relation between CCT of LEDs

and SVI index. Low CCT of the lamps does not significantly affect their

SVI value. Unfortunately, those kind of lamps are less attractive in

applications because of their low .

Title Urban park lighting as a source of botanical light pollution Type Journal Article
Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL
Volume 11 Issue 3 Pages 90
Keywords Plants
Abstract That paper describesthe relative impact of anartificial lighting deviceon botanical light pollution, consideringspectral power distribution (SPD in the lighting area. This impact is described by the Relative-to-Moon Photosynthesis Index (RMPI)and Induced Phytochrome Index (IPr). We found that in the case when lighting is realized by using LED luminaires instead of high-pressure sodium (HPS) or metal halide (MH) lamps, the influence of spectral light on plant vegetation process amplifies. Additionally,our research shows that estimating botanical light pollution on the basis of lamps’CCT is not the best method and that using SPD is better for this purpose.
