According to Codex Alimentarius, pesticides are considered as chemicals that prevent, suppress, destroy and repel some pests during manufacture, storage, transport or processing of food, feed and agricultural goods. These chemicals can also be used as plant growth regulator, as defoliant, agent inhibition. The purpose of this study was to evaluate the content of organochlorine pesticides in home-grown vegetables products. The objectives were the establishment of the working matrices and the organochlorine pesticides determination in the matrices chosen by GS method. Due to the high cost of analysis, the vegetable matrix was consisted in 12 sample- lettuce and spinach samples grown in garden and roots samples (carrots, parsley, parsnip and celery) from both home-grown production. Organochlorine pesticide residues were extracted from the sample with acetonitrile and petroleum ether, purified by passage through florisil column and eluted with a mixture of ethyl ether and petroleum ether. Concentrated eluate was subjected to gas chromatographic determination.In all examined samples, there were identified organochlorine pesticide residues with high residual, HCH, DDE, DDT, DDD, endosulfan, and heptachlor, some being above the maximum allowed by European legislation

Due to the changes that have taken place over the last period of time, at the level of the macromedium and micro-environment factors of an agricultural enterprise, the agricultural producer is challenged to have an activity characterized by performance and competitiveness. In order to support the needs of consumers of agri-food products, which suffer from many changes, it is important for the agricultural entity to obtain agricultural production at a higher quality level. This paper presents the stages of the establishment of a vegetable farm with professional solariums and greenhouses, having as main activity the tomato, pumpkin and spinach crops. During the paper, the elements of the micro-society (objectives, risks, market strategies), as well as elements of the macromedi (economic, technological, politico-legislative, natural) will be presented. It is also attempted to briefly present the aforementioned crop technology of vegetables. As a method of analysis, a feasibility study on setting up a vegetable farm will be presented in this paper, taking into account annual expenditure, estimated revenue, including estimated production costs. After analyzing all the elements presented, the section "Results and Discussions" presents the financial result and the recovery of the investment, taking a five-year horizon.

The consumption of fruit and vegetables is essential for a healthy lifestyle and preventing many diseases. Still, in Romania the consumption is very low compared to the countries of the European Union. The main aim of the research was to determine the consumer behavior of local fruit and vegetables for the urban consumers in Cluj-Napoca. A study was conducted using the questionnaire. Result indicated that consumers purchase fruit and vegetables 2-3 times per week, and most of them spend between 50-80 lei per week for this food category. The most preferred place of purchase is the farmers markets and the local origin is a very important criterion during the decision-making process of purchase.
