Lead is one of the most important pollutants in the environment. Plants absorb lead when it is present in the environment. Lolium perenne L and Lactuca sativa var. capitata L are species used for toxicity tests. The experiments were performed with different concentrations of lead nitrate (0.05 g/L; 0.1g/L; 0.5 g/L; 1 g/L). Test targets refer to seeds germination, the growth of seedlings, fresh biomass weight, dry biomass weight and physiological parameter (dry weight/fresh weight; the quantity of dry mass from 100 g fresh weight) at seven and fourteen days. Lead toxicity inhibits germination of seeds and reduces the growth of seedlings. Lead can decrease germination percent, root length and strain length. Seedlings growth inhibition is not necessarily correlated with biomass reduction.

In this paper we studied the emergence and development of pear scab (Venturia pirina), as well as the combat methods, testing a couple of fungicides. The aim of the research has been to highlight the resistance, respectively the sensitivity of some pear varieties against the fungi attack, in order to make recommendations for the new plantations, as well as the testing of 7 fungicides, remarking the product with the highest biological effectiveness. The researches were conducted in the years 2013-2014 at the company SC Mecanochim Lapusel, Maramures County. The experiments were conducted on plots planted with the Olivier de Serres and Bergamotte Crassane varieties. The attack was calculated determining the attack frequency, intensity and degree. The linear-interrupted method was used, comprising 3 variants of 5 trees each. Analyzing the climate data, it has resulted that in 2013 scab had favourable development and attack conditions. The Olivier de Serres variety was noted for its resistance to fungus attack, with a frequency of 0.2-1.3% on fruits and insignificant frequency on leaves, for all 7 tested product variants. The Bergamotte Crassane variety was placed on the other end, with a higher frequency and intensity, both on fruits (2-3%) and on leaves (2.5-3.5%). The infections diminished in 2014 due to the unfavourable climatic conditions. Three products had better results, from the seven tested products, thus: Alcupral 50PU, Stroby DF and Chorus 50 WG.

This study has examined the response of two species of the blueberry bushes: Elliot and Bluecrop cultivated in the climate conditions of the years 2014 and 2015 to the attack of the Phomopsis vaccinii; we have also testedand determined the biological efficiency of three fungicide products in order to recommend the best of them to be used in the bushes treatment. The attack was calculated by determining the disease frequency (F%) and its intensity (I%). We also calculated the biological efficiency for the three selected products, considered as being the best ones. We utilized the interrupted-linear setting method which consists of 5 plants/three repetitions / product and we monitored 3 plants from each repetition; 2 marginal plants were for untreated control. Our analysis of the two species pointed that the Bluecrop species has a much higher sensitivity against the pathogen than the one discovered in the Elliot species. The calculation of the biological efficiency proved that the best product Funguran OH 50 PW (90,5%) was followed by Alcupral 50 PU (88,8%) and the Copac ( 86,2%) for the Elliot variety, occupied the last place; the same hierarchy with smaller values was found for the Bluecrop variety.

During June, 2017, ten products from the food bases category have been studied. The companies and the products types were noted and the manufacturer’s labels were studied. It has been found that the rules on the labeling of food bases are respected. The study had the following objectives: studying the ingredients and the nutritional composition and identifying the additives used in the manufacture of the product. Studying product labels also highlighted an increased salt and sugar content. The percentage of dehydrated vegetables was between 4.49% and 38%. The vegetables content was different for the food bases investigated. The 40% of food bases had between nine and ten dehydrated vegetables, the 60% had between four and six dehydrated vegetables. Additives added to foods during processing are important to improve their appearance and to extend their shelf life.

The milk samples were yielded by manual milking from a goat farm that was maintained in extensive system, at monthly intervals during the production period (spring, summer, autumn). Goat milk from a traditional stall in the Maramures County, depending on the lactation period and the season has been analyzed in this study. The milk samples were collected aseptically and transported in laboratory for microbiological analysis. During springtime, when milking is done three times a day, and the amount of milk is higher, the total number of germs is 77.8×103 CFU/ml. A smaller number compared to the number of microorganisms recorded in the summer (97.3×103 CFU/ml) when milking is done twice a day and there are higher temperatures. During autumn, in the conditions of low milk production, at the end of the lactation period and when the samples are harvested only once a day, the number of microorganisms was 81.5×103 CFU /ml. Somatic cells from milk indicating an excess of the normal values especially towards the end of the lactation period. Particular attention should be paid to hygiene conditions when handling milk, to improve its quality. Thus, goat milk has a higher bacterial load (SPC) during summer, and SCC exceeds the recommended limits, especially in the autumn.
