There are two basically different methods, i.e. <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;in vitro&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;&amp;quot;In the test tube&rdquo; from the Latin &amp;lt;em&amp;gt;vitrum&amp;lt;\/em&amp;gt; &ndash; &amp;lt;em&amp;gt;glass,&amp;lt;\/em&amp;gt; referring to reactions outside the organism, sometimes under participation of autologous physiological conditions.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>in vitro<\/span> or <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;in vivo&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;From the Latin &amp;lt;em&amp;gt;vivus&amp;lt;\/em&amp;gt; &ndash; alive, characterising reactions or processes that take place in the living organism under physiological conditions.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>in vivo<\/span>, that toxicologists, mostly chemists, medical scientists or biologists, may choose for conducting such studies.<\/p>\n<p>In addition to assessing the possible biological effects of innovative materials or nanomaterials inside the human body, it is important to evaluate the materials&rsquo; epidemiological impacts, i.e. their effects on the health of the overall population. Workplace hazards, for example, are among the risks that need to be studied. Additionally, the influence of innovative materials such as engineered nanoparticles on all organisms in our environment has to be considered and studied. Does an environmental &ldquo;pollution&rdquo; with nanoparticles exert similar effects compared to chemicals?<\/p>\n<p>For all that, it is important to point out that the health hazards of any chemical substance almost always depend on the <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;Concentration&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;Collective term for measures related to volume, e.g. g\/ml, kg\/l, g\/cm&amp;lt;sup&amp;gt;3&amp;lt;\/sup&amp;gt;. Due to their high surface\/volume ratio, for nanoparticles instead of mass-related, surface-related concentration ranges, e.g. cm&amp;lt;sup&amp;gt;2&amp;lt;\/sup&amp;gt;\/ml is frequently used.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>concentration<\/span>. According to Paracelsus (1493-1541), &ldquo;all things are poison; there is nothing without poison; only the <span class=\"glossaryLink\"  aria-describedby=\"tt\"  data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;Dose&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;Term for the amount of a substance, which acts within a specific time or to a specific organism (see also LD50). In toxicity testing of nanoparticles, dose information, such as number of particles\/cell or &micro;g particles\/cm&amp;lt;sup&amp;gt;2&amp;lt;\/sup&amp;gt; surface area are used.&lt;\/div&gt;\"  data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>dose<\/span> makes a thing non-poisonous&rdquo;. It has remained valid until the present day that any substance has a biological\/toxicological effect. Only the concentration (or dose) that is taken up by the organism decides whether that effect is negative or not. However, there are exceptions from this rule, especially carcinogenic substances or endocrine disruptors may induce biological effects without a clear concentration- or dose dependency.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The discovery or development of novel chemicals or materials creates a demand of new knowledge as regards the related potential biological effects and health hazards.
