Environmental Quality Control Laboratory

Base Knowledge

There is no recommended background knowledge.

Teaching Methodologies

Theoretical contents are presented at the beginning of classes, being then applied in the performance of laboratory work. 8 experimental works will be carried out.

Learning Results

At the end of this training unit the trainee should be able to:

Identify and experimentally quantify the chemical composition of foods.

Identify and experimentally quantify the main microorganisms used to monitor drinking water and food.

Identify and experimentally quantify the main chemical contaminants present in drinking water and food.

Program

1. Determination of the main microbiological parameters analyzed in drinking water and food. Determination of molds and yeasts, total coliforms, faecal coliforms, Escherichia coli, total microorganisms, faecal streptococci, Clostridium perfringens (spores), Pseudomonas aeruginosa, Staphylococus aureus and Salmonella.

2. Determination of the main physical-chemical parameters analyzed in drinking water and food. Determination of dry matter and fat, protein and sugar content. Acidity and alkalinity. Analysis of heavy metals, nitrites, nitrates, ammonium, phosphates, alcohols, phenols and color.

Grading Methods

Trainees will be subject to summative assessment in which the final result will be defined on a scale of 0 and 20 values. The trainee who achieves at least a classification of 10 values ​​in the total summative assessment components obtains approval in the training unit. The trainee's achievement results from a continuous summative assessment, taking into account the execution of the work and the respective reports, as well as attendance, punctuality, behavior, relationship and performance in class

The Final Classification of the Course Unit will result from the application of the following equation:

CFinal=0.11×T1+0.11×T2 +0.11×T3+0.11×T4+0.11×T5+0.11×T6+0.11×T7+0.11×T8+ 0.12×Out

where T is the classification obtained in the works and respective reports and Out the classification obtained in attendance, punctuality, behavior, relationship and performance in classes.
