The aim of this article is to describe how the interdisciplinary approach to teaching English, based on some aspects of content and language integrated learning (CLIL) methodology, is implemented by combining environmental science, sustainable development, and the English language. The paper introduces an English as a Second Language (ESL) course book designed for students of Environmental Monitoring, who study biomonitoring within the framework of an experimental CLIL course. At the end of each topic students present a project which proves their acquisition of professional and language knowledge. As a result, students obtain professional competence in a wide range of skills. More importantly, this goal is achieved without extending the curriculum.

Celem artykułu jest przedstawienie sposobu wdrożenia interdyscyplinarnego podejścia do nauczania języka angielskiego opartego na wybranych aspektach zintegrowanego kształcenia przedmiotowo-językowego (CLIL) poprzez połączenie nauki o środowisku i rozwoju zrównoważonym z nauczaniem języka angielskiego. W artykule opisano podręcznik do nauki języka angielskiego jako języka drugiego (ESL) przeznaczony dla studentów monitorowania środowiskowego, studiujących biomonitoring w ramach kursu CLIL. Należy zaznaczyć, że na końcu każdego tematu studenci prezentują projekt, w którym demonstrują wiedzę merytoryczną i językową, jaką sobie przyswoili. Cel ten jest osiągany bez zwiększania wymiaru czasowego programu nauczania.

Objectives: To describe blood lead (Pb-B), cadmium (Cd-B) and mercury (Hg-B) levels in children living in urban, industrial and rural areas in Fez city (north of Morocco) and to identify the determinants and some renal effects of exposure. Material and Methods: The study was conducted from June 2007 to January 2008 in 209 school children (113 girls, 96 boys), aged 6-12 years, from urban, industrial and rural areas in Fez city. Interview and questionnaires data were obtained. Blood and urinary samples were analyzed. Results: The mean of blood lead levels (Pb-B) in our population was 55.53 μg/l (range: 7.5-231.1 μg/l). Children from the urban area had higher blood lead levels (BLLs) mean (82.36 μg/l) than children from industrial and rural areas (48.23 and 35.99 μg/l, respectively); with no significant difference between boys and girls. BLLs were associated with traffic intensity, passive smoking and infancy in the urban area. The mean of blood cadmium levels (BCLs) was 0.22 μg/l (range: 0.06-0.68 μg/l), with no difference between various areas. Rural boys had higher BCLs mean than rural girls, but no gender influence was noticed in the other areas. BCLs were associated with the number of cigarettes smoked at children's homes. The blood mercury levels (BMLs) mean was 0.49 μg/l (range: 0.01-5.31 μg/l). The BMLs mean was higher in urban and industrial areas than in the rural area with no gender-related difference. BMLs were associated with amalgam fillings and infancy in the urban area. About 8% of the children had BLLs ≥ 100 μg/l particularly in the urban area, microalbuminuria and a decrease in height were noticed in girls from the inner city of Fez and that can be related to high BLLs (89.45 μg/l). Conclusions: There is a need to control and regulate potential sources of contamination by these trace elements in children; particularly for lead.

Objectives 1,5-Naphthalene diisocyanate (NDI) is used in the plastic industry as a curing agent. 1,5-Naphthalene diisocyanate is classified as a sensitizing agent. The objective of this study has been to develop biomonitoring methods for the evaluation of exposure to NDI. Material and Methods We obtained blood and urine samples from a group of 20 male workers exposed to NDI. The workers answered a questionnaire about their exposure history, job description, the number of years with the company and the time spent working with NDI over the 10 days of the study. Total plasma, albumin, and urine were analyzed for the presence of 1,5-naphthalenediamine (NDA) after acid hydrolysis using gas chromatography-mass spectrometry (GC-MS). Results 1,5-Naphthalenediamine was found in about 60% of the samples obtained from the workers. 1,5-Naphthalenediamine was obtained after acid hydrolysis of plasma, albumin, and urine at levels up to 1.5 pmol NDA/mg of plasma proteins, 1.15 pmol NDA/mg of albumin, and 55.3 pmol NDA/ml of urine, respectively. Conclusions 1,5-Naphthalenediamine found in urine correlates best with the plasma levels (r = 0.91, p < 0.01). The albumin-adduct levels did not correlate with the NDI-specific immunoglobulin E (IgE) or total IgE present in the workers. The adduct and metabolite levels correlate with the air levels of NDI.
