Emission Spectra02:39

Emission Spectra

75.9K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color Vision01:24

Color Vision

1.4K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Positron Emission Tomography01:29

Positron Emission Tomography

7.0K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...

Changes in Skin Color: Clinical Perspectives

3.4K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Summary
This summary is machine-generated.

Polychlorinated biphenyls (PCBs) emitted from paint colorants can reach environmentally relevant concentrations. Even fully chlorinated PCBs and those in low concentrations can be released, posing a risk to indoor air quality.

Area of Science:

  • Environmental Chemistry
  • Toxicology
  • Occupational Health

Background:

  • Polychlorinated biphenyls (PCBs) are persistent organic pollutants and known human carcinogens.
  • PCBs are byproducts of pigment manufacturing and are present in colorants used in consumer paints.
  • These PCBs can be emitted from paints into the air, posing potential health risks.

Purpose of the Study:

  • To quantify the gas-phase emissions of total PCBs (∑PCBs) from paint colorants.
  • To investigate the rate and extent of PCB congener release from freshly applied colorants.
  • To determine factors influencing PCB emission rates from paints.

Main Methods:

  • Polyurethane foam (PUF) was used to capture gas-phase PCB emissions from freshly applied colorants.
  • Emissions were monitored over a 6-week period.
  • PCB concentrations in colorants and on PUF were analyzed.

Main Results:

  • PCB emissions were detected on PUF within 1 day of application.
  • All PCBs initially present in the colorant were found on the PUF after 6 weeks.
  • Lower chlorinated PCBs were released faster than higher chlorinated congeners.
  • Even highly chlorinated PCB209 was emitted from green colorant.
  • PCB emissions can reach environmentally relevant concentrations (≥500 pg m⁻³) within hours.

Conclusions:

  • Paint colorants are a source of airborne PCBs, contributing to indoor air contamination.
  • The rate of PCB emission depends on the congener's properties and environmental factors like water presence.
  • PCB emissions from paints pose a significant environmental and potential health concern.
