Sedimentary pigment analyses showed that photoprotective compounds were abundant and UVR indices were elevated in the oldest sediments, but declined 3-fold to modern values ca. 3000-4000 yr BP (Figure 6). As sedimentary organic matter content also declined at this time, we infer that reductions in UVR did not arise from increased DOC content within the lake (see methods... 

Marine algae hold immense potential to be utilized as photoprotective elements. Proper utilization of this resource would pave a pay for future detonation in the cosmeceutics and medicinal food market. Advanced biotechnological approaches need to be implied to ocean sciences to explore the vast prospective of these photoprotective agents. Strategies need to be formulated for the appropriate usage of the marine algal photoprotective compounds as an answer to the photodamage caused by UVA/UVB or even the xenobiotics.

The mode of action of quenchers, however, is not dependent on the thickness of the film to be protected. Quenchers are photoprotective compounds that can take up and conduct away energy that has been absorbed by chromophores, such as hydroperoxide, which are present in PE film. Organo-nickel compounds are quenchers that also act as decomposing agents of hydroperoxide.
