Measures of prevention and control against polycyclic aromatic hydrocarbons (PAHs) focus on an official food control, a code of best practice to reduce PAHs levels by controlling industry and in the development of a chemopreventive strategy. Regulation (EU) 835/2011 establishes maximum levels of PAHs for each food group. In addition, Regulations (EU) 333/2007 and 836/2011 set up the methods of sampling and analysis for its official control. Scientific studies prove that the chemopreventive strategy is effective against these genotoxic compounds effects. Most chemopreventive compounds studied with proven protective effects against PAHs are found in fruit and vegetables.

The present article analyses the preferences of the deaf who use sign language and are users of the TV interpretation service to sign language, as well as the characteristics with which TV channels provide that service in television in Spain. The objective is to establish whether the way in which the aforementioned accessibility service is provided matches the preferences of users or differ from them. The analysis presents the opinion on this service of the deaf that use the Spanish sign language as their first language for communication. A study has also been conducted on the programmes broadcast with sign language during week 10-16/03/2014. The main data collected reveal that the deaf are dissatisfied with broadcasting times. They ask for news programmes with sign language, they would rather have the interpretation carried out by deaf people who use sign language and they prefer that the interpreter is the main image on screen. Concerning the analysis of the programmes broadcast, the study shows that the majority of programmes with sign language are broadcast at night, they are entertainment programmes, the interpretation is carried out by hearing people who use sign language and that their image is displayed in a corner of the screen.
