“…A decrease in the yield and WUE of the three lettuce varieties was observed during the summer growing season as a result of both high air temperature and insolation and low rainfall. Abreu et al (2014) also found a decrease in the yield of different lettuce varieties when grown in the summer season.…”

Three field experiments were carried out in a tropical environment in Brazil in order to evaluate the effect of planting date on crop evapotranspiration (ET c), crop coefficient (K c) and water use efficiency (WUE) of three lettuce (Lactuca sativa L.) cultivars grown in different seasons (autumn, winter and summer) under tropical climate. ET c values were obtained through the soil water balance method and reference evapotranspiration (ET o) through the Penman-Monteith method, using data collected in an automatic weather station located close to the experimental area. The results of the research showed that the mean values of ET c and K c for lettuce were 3.5 mm day-1 and 0.82, respectively. The curly cultivar showed the highest yield (40.8 kg ha-1) during the autumn transplanting date. Results also showed that the three lettuce varieties have different responses to the climatic conditions. The greatest WUE was observed for the three lettuce varieties when they were grown during the autumn growing season, and the lowest values occurred during the winter growing season.

“…Nevertheless, the research adds to our understanding by showing that Indian mustard, when grown in calcareous soils, is attributable to the presence of highly soluble uranyl carbonate complexes, which are potentially important for generating rational policy mandates. In the taxonomic context of crops, U concentration in Lactuca sativa demonstrated notable variations, with the Romana variety exhibiting higher accumulation and retention in the roots, while the Marady variety showed increased accumulation in the leaves [50]. When comparing the recommended limit of 11.7 ppm set by UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation), the regions of Canada and Portugal exhibited the highest levels of U accumulation, particularly in RDH and LTT, with concentrations ranging from 3 to 14 mg/kg [51][52][53].…”

Uranium (U) and fluoride (F−) contamination in agricultural products, especially vegetable and cereal crops, has raised serious concerns about food safety and human health on a global scale. To date, numerous studies have reported U and F− contamination in vegetable and cereal crops at local scales, but the available information is dispersed, and crop-wise differences are lacking. This paper reviews the current status of knowledge on this subject by compiling relevant published literatures between 1983 and 2023 using databases such as Scopus, PubMed, Medline, ScienceDirect, and Google Scholar. Based on the median values, F− levels ranged from 0.5 to 177 mg/kg, with higher concentrations in non-leafy vegetables, such as Indian squash “Praecitrullus fistulosus” (177 mg/kg) and cucumber “Cucumis sativus” (96.25 mg/kg). For leafy vegetables, the maximum levels were recorded in bathua “Chenopodium album” (72.01 mg/kg) and mint “Mentha arvensis” (44.34 mg/kg), where more than 50% of the vegetable varieties had concentrations of >4 mg/kg. The concentration of U ranged from 0.01 to 17.28 mg/kg; tubers and peels of non-leafy vegetables, particularly radishes “Raphanus sativus” (1.15 mg/kg) and cucumber “Cucumis sativus” (0.42 mg/kg), contained higher levels. These crops have the potential to form organometallic complexes with U, resulting in more severe threats to human health. For cereal crops (based on median values), the maximum F− level was found in bajra “Pennisetum glaucum” (15.18 mg/kg), followed by chana “Cicer arietinum” (7.8 mg/kg) and split green gram “Vigna mungo” (4.14 mg/kg), while the maximum accumulation of U was recorded for barley “Hordeum vulgare” (2.89 mg/kg), followed by split green gram “Vigna mungo” (0.45 mg/kg). There are significant differences in U and F− concentrations in either crop type based on individual studies or countries. These differences can be explained mainly due to changes in geogenic and anthropogenic factors, thereby making policy decisions related to health and intake difficult at even small spatial scales. Methodologies for comprehensive regional—or larger—policy scales will require further research and should include strategies to restrict crop intake in specified “hot spots”.

“…Studies in soils with current and ancient mining activities have been mainly focused on metal/metalloid accumulation by plants and strategies to reduce their concentration (Santibáñez et al 2008;Monaci et al 2011;Madeira et al 2012;Abreu et al 2014). The reason is that their transfer to the food chain has been recognised as a risk by the European Union, which has set maximum levels with a view to reducing their presence in foodstuffs (Commission of the European Communities 2006).…”

Influence of compost of sewage sludge and low-quality water on pesticide uptake by tomato plants grown in an iron mine soil

Purpose In mine soils, especially from arid or semiarid areas, the use of low-quality water for irrigation is a usual practice. Therefore to fill this gap, different experiments have been carried out to evaluate the effect of compost, pesticide and wastewater on the growth of tomato plants in a mine soil located at an iron extraction area. Materials and methods Soils proceeded from Alquife mine wastes whose most outstanding characteristics are alkaline conditions, low organic matter and electrical conductivity and high As concentration. The compost of sewage sludge (CSL) used to amend this soil had a slightly acid pH (6.8), EC 3.0±0.07 dS m -1 (1/10 ratio, m/V) and 10 % organic carbon (OC) content. Irrigation was performed with distilled water (DW) or wastewater (WW) and two pesticides, the insecticide thiacloprid and the fungicide fenarimol, were applied to the soil. Tomato was grown directly from seeds on each pot. Four treatments with addition of pesticides were considered. For comparison purposes, two additional treatments without pesticides were also included.
