Review of literature on stress management project

The two main issues considered in this review are the evidence for the ability of these NPs to penetrate the skin to reach viable cells and the potential toxicity exerted by them. This review is a further update to include relevant literature that has been published between May and August The majority of in vitro studies using both animal and human skin and in vivo studies have shown that both ZnO and TiO2 NPs either do not penetrate or minimally penetrate the stratum corneum and underlying layers of skin.

This suggests that systemic absorption, hence toxicity, is highly unlikely.

What is a Literature Review?

In conclusion, on current evidence, neither TiO2 nor ZnO NPs are likely to cause harm when used as ingredients in sunscreens and when sunscreens are used as directed. Introduction Nanoparticle characteristics Dermal exposure Cytotoxicity and genotoxicity Conclusion Bibliography 1.

Introduction Inorganic UV filters zinc oxide ZnO and titanium dioxide TiO2 have been used as ingredients in sunscreens for over three decades.

However, one apparent disadvantage of ZnO and TiO2 is that in their macroparticulate bulk form in sunscreens, they are visible on the skin as an opaque layer resulting in reluctance of consumers to use the products. This undesirable visual effect has been addressed by decreasing the particle size of these metal oxides to nanoparticle NP form see Section 2.

When used in this NP form, these oxides cannot be seen on the skin but retain or even augment their UV-sunscreening properties. These NPs are particularly useful in sunscreens because of their intrinsic ability to filter ultraviolet UV A as well as UVB wave length spectra, thus providing broader protection than any other sunscreening agent.

A review on these issues was first published by the TGA inwhich was updated in and again in This scientific review report is limited to the review of safety concerns surrounding ZnO and TiO2 NPs present in sunscreens. The two main issues considered in this review are the evidence for ability of these NPs to penetrate the skin to reach viable cells and the potential toxicity exerted by them.

Nanoparticle characteristics For the purpose of this report, the definition of TiO2 and ZnO NPs includes materials within the nanosize range of 1 to nm.

Eclipse Project Handbook

Nanosized TiO2 and ZnO exist in three separate states: Primary particles cluster together to form aggregates and are the smallest units present in a final sunscreen formulation Butler et al.

The larger agglomerates form when aggregates bind loosely during the manufacturing process Schilling et al. These are not efficient UV absorbers so they need to be broken down into the more efficient aggregates, which are chemically bound.

This review includes assessments of NP preparations that contain aggregates and agglomerates. The latter have been included because of their yet unclear potential to disaggregate and disagglomerate when applied on the skin in a sunscreen formulation.

A preliminary study by Bennett et al. Thus, any potential hazard linked with nanosized particles is likely to be reduced if these particles aggregate and form structures above the nanoscale, which then do not dissociate into smaller NPs, thus reducing their ability to penetrate the skin.

Working management of stress involves preparing role occupants to. Mercury is a toxic heavy metal which is widely dispersed in nature. Most human exposure results from fish consumption or dental amalgam.

Mercury occurs in several chemical forms, with complex pharmacokinetics. Mercury is capable of inducing a wide range of clinical presentations. Diagnosis of mercury toxicity can be challenging but can be obtained with reasonable reliability.

Stress Management Literature Review. STRESS MANAGEMENT IN A WORKING ENVIRONMENT Stress is a perceptional phenomenon resulting from a comparison between the demand on a person and his ability to cope. An imbalance in this mechanism, when coping is important, gives rise to the experience of stress, and to the stress response (Cox, ).
