Nine hundred sixty imported and three hundred and eighty three agricultural crop samples were gathered from regions in southern Jordan and analyzed for pesticide residues in 2020 and 2021. The results for both local and imported samples showed that there were no detected pesticide for the banned organochlorine pesticides. There were 6.53% and 7.92% of local and imported crop samples, respectively, contained residues more than the adopted maximum residue limits (MRLs). In addition, there were 12.53% and 10.73% of the monitored local and imported samples, respect- tively contained residues less than the MRLs. There were 80.94% local and 81.35% imported samples of the remained analyzed ones without detect detectable residues. It is recommended to keep monitoring the pesticide residues in all environmental components including the agricultural crops locally and imported ones to protect human health of the citizens and the environment, and to assess the decision makers to take the right decisions concerning pesticide handling and registration.
Tabuk region is situated in the northwestern side of the Kingdom of Saudi Arabia; its strategic location is a main center connecting the three old continents, Europe, Africa, and Asia, making it one of the most promising and suitable region for industrial investment in mining industries, agriculture, fisheries, livestock, crafts, and tourism. \nThe importance of this region and its futuristic growth stands as a promising source for development and investment in this region, in order to achieve the VISION 2030 of Kingdom of Saudi Arabia. Giga projects like Red Sea Project, NEOM, & Line are under development, and projects will flourish greatly in this region in a way that suits the expected growth of the kingdom\'s economy and population. This is a preliminary review about the published data, discussing the important aspects of Tabuk region in light of heavy metals and its toxicity in ground water and marine organism. It further interprets the importance and the value of coastal ecosystems in Tabuk region. While the gaps in data and results regarding metal pollution resulting from all major activities in multiple sectors (desalination plants, industrial plants and oil refineries) in the Tabuk region, a modest redefinition of the priorities of the existing processes would be required. Recommendations, temporal monitoring and regional strategies are provided to increasingly promote the effectiveness and competence of coastal region administration.
The Mesoamerican region is center of origin, domestication, and diversification of maize. In this ecogeographic context, the objective was to evaluate the variation in the phenolic compounds, antioxidant activity and concentration of minerals in the grain of a population collection of yellow maize landraces from southeastern Mexico. During 2016, samples of landraces of yellow maize were collected and integrated into 32 populations and experimental varieties, which were planted in two locations in Oaxaca, Mexico, under a random block design. At harvest, a sample of grain was taken, which was grounded to evaluate the polyphenolic compound contents and antioxidant activity by UV–visible spectrophotometry, and macro- and microelement contents were determined using inductively coupled plasma–optical emission spectrometry. The effect of crop location was significantly greater than the effects of populations and location-population interaction on polyphenol contents and concentration of Ca, P, Mg, K, Na, S, Cu, Fe, Mn and Zn. In the Amatengo locality, a higher macroelement contents were recorded, and in the second locality, the concentration of microelements, polyphenols, and flavonoids contents were higher. The populations showed high variability, with significant interactions with crop location in bioactive compounds, antioxidant activity and Ca, Cu, Na, Mn and S contents.
The objective was to know the perceptions and strategies of nursing professionals about the medication dispensing process carried out in a central nursing station of an emergency care unit. This is an exploratory, descriptive, qualitative research carried out with 43 nursing professionals. Data were collected from June to August 2018 through semi-structured interviews with subsequent discursive textual analysis. Two units were formed regarding weaknesses/difficulties and strategies for the medication dispensing process at the central nursing station. These units resulted in seven categories: prescription, dilution/time; training and elaboration of a standard manual; professional attention; extinction of the central nursing station; and idealization of a central station in the unit. The weaknesses were: insecurity in administering medications diluted by colleagues, prescription errors, and inattention to the stages of the process. Professional updates, training, elaboration of manuals, and a greater number of professionals were suggested as strategies.
