Project Consortium in order to track the project progress <strong>and</strong> meet its administrative objectives.<br />

The main objective <strong>of</strong> this work package is to assess the risks caused by the NMs studied in SANOWORK in<br />

all the stages <strong>of</strong> their life cycle. The risk assessment characterization will be done on the different NMs<br />

before <strong>and</strong> after applying the risk management strategies proposed by SANOWORK. The data obtained<br />

from the risk assessment will be used to inform the industrial partners about the strategies to implement in<br />

their processes to create a safer workplace environment.<br />

In this WP, we will develop databases for NMs along their life cycle which will be versatile to include new<br />

data from other sources. These databases will include description <strong>of</strong> materials <strong>and</strong> processes, their<br />

applications, their physico-chemical properties <strong>and</strong> their toxicological pr<strong>of</strong>ile. These data will be generated<br />

in the project as well as included from literature sources <strong>and</strong> will be used in the risk characterization.<br />

The collected information <strong>and</strong> risk characterization transfer to insurance companies will be one <strong>of</strong> the<br />

relevant objectives <strong>of</strong> this WP2.<br />

Strictly connected with the sustainability assessment <strong>of</strong> the proposed strategies is the Cost / Benefit<br />

evaluation <strong>of</strong> the proposed strategies, that will be based on cost analysis <strong>and</strong> evaluation <strong>of</strong> process<br />

efficiency <strong>and</strong> NMs functional properties BEFORE <strong>and</strong> AFTER the introduction <strong>of</strong> Risk Remediation<br />

Strategies.<br />

The aim <strong>of</strong> this work package is to assess risks associated with chronic <strong>and</strong> accidental worker exposure<br />

scenarios applied to Processing Lines 1-6 at pilot-scale levels. Therefore the following specific objectives are<br />

proposed:<br />

• Devise a qualitative worker exposure assessment method based on design or control approaches;<br />

• Develop a control b<strong>and</strong>ing risk assessment methodology to evaluate risks at the pilot industrial<br />

scale level;<br />

• Develop a quantitative worker exposure methodology by performing on-site exposure<br />

measurements, to provide inputs to the control b<strong>and</strong>ing (CB) risk assessment methodology.<br />

The main objective <strong>of</strong> this WP is the development <strong>of</strong> the following Risk Remediation Strategies <strong>and</strong> their<br />

integration within the target processing lines:<br />

Strategy I: Coating by organic or inorganic based additives.<br />

Strategy II: Control <strong>of</strong> colloidal forces <strong>and</strong> disintegration <strong>of</strong> NPs.<br />

Strategy III: Integration <strong>of</strong> spray-drying process.<br />

Strategy IV: Immobilization by organic film coating deposition.<br />

Strategy V: Wet milling.<br />

Target Processing Lines:<br />

Processing Line 1: ZrO2 NPs as additives in the chemical industry .<br />

Processing Line 2: ZrO2 NPs as additives in ceramic materials.<br />

Processing Line 3: Polyamide Nan<strong>of</strong>ibers as membrane components for filter industry.<br />

Processing Line 4: TiO2 Nan<strong>of</strong>ibers as photocatalytic components in Solar Cells.<br />

Processing Line 5: TiO2 NPs as photocatalytic additives <strong>and</strong> Ag NPs as antibacterial additives in the ceramic<br />

industry.<br />

Processing Line 6: MWCNTs as additives in plastic industry.<br />

Strictly connected with the above described objective is the assessment <strong>of</strong> process efficiency as well as <strong>of</strong><br />

NMs functional properties. This objective aims to provide useful information for COST / BENEFIT evaluation<br />

performed by WP6.<br />

In order to assess the performance <strong>and</strong> the validity <strong>of</strong> proposed Risk Remediation Strategies (WP4) the WP5<br />

will:<br />

1) Identify the hazardous properties <strong>of</strong> NMs, by reviewing the available literature data <strong>and</strong> relying on<br />

the thorough physico-chemical characterization performed within WP4;<br />

2) Assess the impact <strong>of</strong> pristine <strong>and</strong> surface modified NMs by using representative <strong>of</strong> exposure<br />

pathways in vitro models: a) primary human cells; b) established mammalian including human cell lines;<br />

3) Determine how the cellular bio-reactivity <strong>of</strong> NMs relates to their physicochemical properties <strong>and</strong><br />

give indications for the development <strong>of</strong> a safe <strong>and</strong> sustainable manufacturing <strong>of</strong> nanoproducts.<br />

The following specific objectives will be pursued:<br />

i) Review toxicological data on selected NMs <strong>and</strong> identify knowledge gaps in hazard which are<br />

expected for such newly synthesized NMs (e.g. nan<strong>of</strong>ibers, new functionalized nanostructures);<br />

ii) Assess cellular responses to the pristine <strong>and</strong> surface modified NMs delivered by WP4 by developing<br />

a testing strategy based on in vitro tests, using human cell models representative <strong>of</strong> the pulmonary <strong>and</strong><br />

cardio-vascular systems;<br />

iii) Implement an hazard characterization strategy in close collaborations with SMEs, by assess cellular<br />
