The relevance of these traditional occupations to the demands of a modern economy has to be defined now. 6Centuries of irrigated agriculture and rice farming have been embedded in Sri Lanka’s cultural traditions, enriching the lives of her people in all aspects. According to the version our mathematics teacher in Istanbul told us, a class of high school students in Germany was misbehaving (much like we were), and to punish them, their teacher told them to add up all of the numbers from one to one hundred.

6There is a charming anecdote about the German mathematician Carl Friedrich Gauss. El desarrollo humano de una comunidad dada puede ser medido y conocido gracias a los esfuerzos que en este sentido realiza la Organizaci Although the HDI is not a comprehensive measure of human development, it is a broader assessment of human well- being and it shows how. Y aunque el IDH no es una medida integral – s. Bien que l’IDH ne soit pas une mesure compl. But the prevailing understanding of the relationship between conflict and employment does not fully recognize the complexity of this relationship – a shortcoming that undermines effective employment policies in fragile states. 6There is no denying that conflict has far- reaching negative effects, including on employment. The imported rice had better quality in terms of the presence of AFs.What are some of the positive changes and some of the less positive ones? People easily ignored it with a common perception that they are poor children, and they are working. The rice which originated from Mexico contained (AFt = 16.9 μg/kg), and those imported from the United States (AFt = 14.4 μg/kg) and Uruguay (AFt = 15.6 μg/kg). The rice imported from France to Spain had AFt of 26.6 μg/kg and from Pakistan AFt of 18.4 μg/kg, showing less AF contamination than the local one. The average total AF (AFt) in the Spanish rice was 37.3 μg/kg, the range was from 1.6 to 1383 μg/kg, the most contaminated samples being from San Juan de Aznalfarache, Sevilla (AFt = 138.6 μg/kg), from Tortosa, Tarragona (AFt = 104.6 μg/kg), and Calasparra, Murcia (AFt = 103.9 μg/kg).

The methodology was validated, the rice samples were concentrated and purified with immunoaffinity columns and were quantified by high-pressure liquid chromatography (HPLC).

The purpose of this study was to identify and quantify AF (B 1, B 2, G 1, and G 2) in 67 rice samples cultivated in Mexico and Spain, and from imported crops collected in 20. Rice is an important cereal but it is often contaminated with aflatoxins (AFs).
