## Abstract

**:**

## 1. Introduction

## 2. Methodology

## 3. Attractor of a Complex System

## 4. Selection of Variables

- ■
- Quality of air outside air (CAE) (The acronyms follow Spanish terms for the variables and are relevant for interpreting Tables).
- ■
- Quality of the inside air (CAI).
- ■
- Quality of the drinking water (CAP).
- ■
- Quality of river and lake water (CAR).
- ■
- Landfill (VR).
- ■
- Food quality (CAC).
- ■
- Chemicals (QMS).
- ■
- Living conditions (CDV).
- ■
- High voltage lines (LAT).
- ■
- Mobile telephone antennae (ATM).
- ■
- Mobile telephones (TFM).
- ■
- Computers (CPS).
- ■
- Household electrical equipment (EEH).
- ■
- Noise (RDO).
- ■
- Exposure to the sun (EAS).

## 5. Results

#### 5.1. Correlation Analysis

_{xy}≥ 0.7). The couple we obtained with r

_{xy}≥ 0.7 are grouped in Table 1.

#### 5.2. Development of Directed Graphs

## 6. Discussion

_{2}explains that the five variables therein have a similar level of concern among these European citizens.

_{3}, with a basin of attraction C

_{3}, and both sets are identical to the correlation graph 0.75, i.e., A

_{2}and A

_{3}= C

_{2}= C

_{3}.

_{4}can be seen below:

_{xy}≥ 0.8), the variable high voltage lines (LAT) are not part of the attractor and the response to this variable could be the cause of the effects of both ATM and TFM (mobile antennas and mobile phones).
