And Risk Assessment

Abstract
A review is proposed of various types of sensoristic approaches to biological
damage and risk assessment. The traditional approach to the toxicity evaluation
of a matrix based on the determination of toxic concentration is replaced by a
sensoristic one. Some sensors that are able to detect risky and dangerous
situations and to evaluate them by screening and marker procedures are
presented. The marker indexes we propose are total organic carbon, total
radicalic concentration, integral toxicity and ecopermanence.
Keywords: TOC analysis, ecopermanence, TiO2 photosensor, biosensor,
integral toxicity assessment, human tissue biosensor.
1 Introduction
There are a continuously increasing number of compounds, both newly
discovered and already known, which are disposed of into the environment and
then pass into the food chain. Very complicated controls and analysis are
required to ascertain whether there are any risks to citizens and users.
These analyses are generally very costly so they are not always completed –
and if they are completed, it may not be as frequently as is necessary – and they
are not permitted everywhere. It is also to be observed that sometimes the
obtained results show that the fear of pollution of the considered matrix is
disproportionate, as the pollution level is insignificant and below dangerous
levels, so that analysis could have been avoided, but obviously this cannot be
foreseen.
So a new approach must be more opportunely adopted: the approach of the
"crossing light", preliminary screening and markers. The first step of this
