“…The Pb results in lettuce samples for the current study showed values that were similar to those from Croatia [ 1 ], Brazil [ 19 ], Chile [ 33 ], and Spain [ 35 ]. In the case of tomatoes, the Pb concentrations obtained by the present study were higher than all the international studies in Table 5 , except from the mining area of India (Andhra Pradesh) [ 46 ], which clearly demonstrate the possible toxicity of Ecuadorian tomatoes, especially those from the four markets where the samples exceeded the CDX 193-95 threshold values [ 22 ].…”

Graphical abstract In most of the samples, each individual metal content does not overpass the FAO/WHO threshold limits, nevertheless 25 % of the tomato samples were near or exceeded the Pb threshold value. The total metals content suggests that there is an important contamination in tomatoes and lettuces commercialized in the markets from Central and South zones of the DMQ. In addition, the organic products analyzed have an alarming metal content that should be considered.

“…Comparatively, most of these studies evaluated the content in chard, especially commercial samples. The content of nitrate observed in these studies varied from very low (<200 mg/kg) and low (200-500 mg/kg) to extremely high (>5000 mg/kg) [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Only the study carried out by Menal-Puey and Asensio [29] reported values in the range of medium (500-1000 mg/kg) and extremely high.…”

Curing meat products is an ancient strategy to preserve muscle foods for long periods. Nowadays, cured meat products are widely produced using nitrate and nitrite salts. However, the growing of the clean-label movement has been pushing to replace synthetic nitrate/nitrite salts (indicated as E-numbers in food labels) with natural ingredients in the formulation of processed foods. Although no ideal synthetic nitrate/nitrite replacements have yet been found, it is known that certain vegetables contain relevant amounts of nitrate. Beta vulgaris varieties (Swiss chard/chard, beetroot, and spinach beet, for instance) are widely produced for human consumption and have relevant amounts of nitrate that could be explored as a natural ingredient in cured meat product processing. Thus, this paper provides an overview of the main nitrate sources among Beta vulgaris varieties and the strategic use of their liquid and powder extracts in the production of cured meat products.

“…Studies had focused on the effect of applying different levels of N, forms, and the time and way of application to leafy crops, as well as nitrate accumulation (Corradini et al, 2018 andTabaglio et al, 2020). Less studies had pointed to the effects of P on the growth and yield of leafy crops and its effect on NO 3 accumulation rate inside the plants' tissues (Sadeghi et al, 2009).…”

Equilibrium Content between Nitrogen and Phosphorus for Lettuce (Lactuca sativa L.) Grown in a Clay Soil

T HIS study aims to investigate the effect of different nitrogen concentrations (60, 120 and 180 mg L -1 ) applied in the form of ammonium nitrate (NH 4 NO 3 ) through fertigation and, also, phosphorus concentrations (15, 35 and 55 mg L -1 ) in the form of phosphoric acid (H 3 PO 4 ), individually or in combination with each other,on the growth parameters and yield of lettuce plants (Lactuca sativa L.), as well as nitrate accumulation in plant tissues. The investigations were conducted under the field conditions during the two growing seasons of 2019/2020 and 2020/2021 at the experimental farm of Dokki site, Giza Governorate, Egypt, following a split plot design. Obtained results indicated that increasing N supplies up to 180 mg L -1 led to concurrent increase in the vegetative growth characters (i.e., plant height, stem diameter, number of leaves per plant and chlorophyll content) of lettuce plants. While the lowest growth and productivity of plants were obtained by applying 60 mg N L -1 . Regarding the effects of P additions, increasing P supply up to 55 mg L -1 increased the growth and productivity of plants during both studied seasons. Interaction effect between N and P levels indicated that 180 mg N L -1 combined with 55 mg P L -1 gave the highest lettuce productivity followed by 180 mg N L -1 combined with 35 mg P L -1 . The weight of lettuce head took the same trend of vegetative growth. The chemical analyses revealed that increase N dose led to increase the content of N, K, Ca and Mg as well as N-NO 3 in plant tissues. Increase P level led to increase the P content. Finally, increase P level led to decrease N-NO 3 and transformation rate of nitrate in plant tissues.
