Life Cycle Assessment

Tool to evaluate the environmental

performance of products

Focuses on the entire life cycle of a product

Indicates results for different impact

categories and compartments

5

Pesticides

Any substance or mixture for preventing

or destroying any pest.

Can cause harm to humans, animals, or

the environment

Major groups: insecticides, herbicides and

fungicides

6

To develop a method of assessing impacts on

human health and ecosystems considering the most

used pesticides

Objectives

To make the general method operable for any kind

of crops (cultures) grown in Mediterranean

greenhouses

7

Objectives

Analytical methods to evaluate pesticide concentration in food.

Compare experimental data from field experiments to data generated through multimedia simulations
