| Fee-fishing operations developed recently in Brazilian agricultural scenery in a rather disordered manner. This study, carried out at the northwest region of São Paulo State, Brazil, focuses on the productive performance of fee-fishing system. Several visits were made monthly to nine fee-fishing establishments, for six months. A questionnaire by owners targeting 13 indicators of the operation's productive performance. Data were submitted to multivariate analysis (MANOVA), principal component analysis (PCA) and cluster analysis. MANOVA indicated significant differences between the fee-fishing operations. The PCA analyses indicated, from the higher coefficient eigenvectors, three attributes for the lakes, such as productive system, fishery management and... |

| Abstract Milk is a very important food for human consumption, mainly due to its content of fat, protein, vitamins and minerals. However, the use of organochlorine pesticides (OCP) for decades has contaminated the soil, water and air, and thus has also contaminated the milk. In this sense, in the present work a review of scientific articles was carried out, between the years 2000 and 2018, related to the evaluation of the degree of contamination of different types of milk by OCPs in different regions of the world. As a result, it was observed that although OCPs have been banned for use in agriculture since the 1980s, these compounds or their metabolites have still been detected in many samples, and in some cases the levels were above the maximum allowed by... |
