“…33 mg per kg body weight [2]. Nitrite consumption has been linked with methemoglobinaemia [3], migraines [4] and chronic obstructive pulmonary disease [5], but most importantly, nitrite has been found to be a precursor in the formation of nitrosamines [6] and aromatic carbocations [7] which are well-known carcinogens.…”

“…Higher NO 2 -values are observed for the medium NO 3 -values (between 50-100 mg/l). The highest concentrations of NH 4 + correlate with the NO 3 -concentrations and the lowest NO 2 -values correlate with the lowest NO 3 -values. The highest NH 4 + concentrations are measured at groundwater samples characterized with a pH ranging between 7.0 and 7.5 pH units, while the lowest concentrations are scatter between 6.9 and 7.9 pH units; whereas NO 3 -concentrations are scatter between 6.9 and 7.9 pH units for all groundwater samples.…”

Worldwide, the groundwater (water well and public spring) is used as drinking water source. The water quality is important due to the possible negative effects on the consumers' health, especially for infants. Nitrogen compounds (NO 2 -, NO 3 -, NH 4 + ) are present as natural components of the nitrogen cycle and their presence in the groundwater is ubiquitous. But, due to the anthropogenic activities high concentrations of nitrogen compounds are release into the groundwater, thereby the chemical compounds concentrations exceed the maximum allowable concentrations (MACs). The purpose of the present study was to assess the content of nitrogen compounds in groundwater, namely private water wells and public springs used as drinking water sources by the Medias town population. The study results show alarming NO 2 -and NO 3 -concentrations; the NO 3 -concentrations exceed 5 times the MAC and NO 2 -concentrations exceed 3 times the MAC.

Intensive agricultural system with high input of fertilizer results in high agricultural output. However, excessive fertilization in intensive agricultural system has great potential to cause nitrate and heavy metal accumulation in soil, which is adverse to human health. The main objective of the present study was to observe the effects of intercropping and inoculation of endophytic bacterium Acinetobacter calcoaceticus Sasm3 on phytoremediation of combined contaminated soil in oilseed rape (Brassica napus L.). The results showed that with Sasm3 inoculation, the biomass of rape was increased by 10-20% for shoot, 64% for root, and 23-29% for seeds while the nitrate accumulation in rape was decreased by 14% in root and by 12% in shoot. The cadmium concentration in rape increased significantly with mono-inoculating treatment, whereas it decreased significantly after intercropping treatment. By denaturing gradient gel electrophoresis (DGGE) and real-time quantitative PCR analysis, the diversity of bacterial community and the number of nirS and nirK gene copies increased significantly with inoculation or/and intercropping treatment. In conclusion, the endophytic bacterium Sasm3-inoculated intercropping system not only improved the efficiency of clearing cadmium from soil without obstructing crop production, but also improved the quality of crop.
