“…The tomato belongs to the vegetable plants which accumulate less nitrates than other vegetables (100 to 150 mg kg -1 ). The effect of climate on nitrate accumulation has been studied [81], and it was found that nitrate content was lower in years that had a high rainfall. In warm and wet years, increased accumulation of nitrate is possible, regardless of whether the nitrogen originates from organic or mineral sources [82].…”

“…The content of nitrates varies in different parts of the plant (Anjana et al, 2006;Santamaria et al, 1999). Accumulation of nitrates also depends on the amount and kind of nutrients in the soil, from the moment of application, amount and content of used fertilizers (Zhou et al, 2000). pH value of soil has the most important role in the accumulation of nitrates in the plant.…”

Summary: This paper presents the results of research on the impact of different varieties and fertilizers on the nitrate content in the leaf and root of parsley. In two-year research, three varieties of parsley were used and three variants of fertilization were applied (mineral fertilizers, organic and organo-mineral fertilizer) as well as a control variant. Nitrate content differed in the leaf and root. Depending on the investigated factors, their content in the leaf ranged from 55.60 to 426.09 mg/kg and in the root it ranged from 98.46 to 688.97 mg/kg. The nitrate content in parsley leaf and root was significantly influenced by the variety and type of fertilizer. The variety "Domestic sawmills" accumulated the minimum nitrate content in the leaf and root of parsley. Mineral fertilization contributed to the accumulation of the highest content of harmful nitrates in the leaf and root of parsley.

“…Given this standard, 17 water spinach genotypes tested in our study can be safe for consumption. The maximum permissible concentration (MPC) of nitrate is 3100 mg/kg FW (Zhou et al, 2000), which means that only five water spinach genotypes can be safe for consumption. Using the combined standards for Cd and nitrate, four genotypes were recognized as safe, i.e.…”

Abstract:Vegetables are important constituents of the human diet. Heavy metals and nitrate are among the major contaminants of vegetables. Consumption of vegetables and fruits with accumulated heavy metals and nitrate has the potential to damage different body organs leading to unwanted effects. Breeding vegetables with low heavy metal and nitrate contaminants is a cost-effective approach. We investigated 38 water spinach genotypes for low Cd and nitrate co-accumulation. Four genotypes, i.e. JXDY, GZQL, XGDB, and B888, were found to have low co-accumulation of Cd (<0.71 mg/kg dry weight) and nitrate (<3100 mg/kg fresh weight) in the edible parts when grown in soils with moderate contamination of both Cd (1.10 mg/kg) and nitrate (235.2 mg/kg). These genotypes should be appropriate with minimized risk to humans who consume them. The Cd levels in the edible parts of water spinach were positively correlated with the concentration of Pb or Zn, but Cd, Pb, or Zn was negatively correlated with P concentration. These results indicate that these three heavy metals may be absorbed into the plant in similar proportions or in combination, minimizing the influx to aerial parts. Increasing P fertilizer application rates appears to prevent heavy metal and nitrate translocation to shoot tissues and the edible parts of water spinach on co-contaminated soils.
