“…In the study of the nitrogen pollution and the transformation processes of NO 3 − in the urban area of Del Campillo city and its surrounding rural area with different land-use types, showed the urban area had the more nitrate concentrations than the rural area. Furthemore, denitri cation processe in groundwater in the urban area was higher than the rural area (Blarasin et al 2020). was located in the western and central areas, while the low-level ones were in the southern and eastern areas.…”

“…Existem poucos trabalhos publicados na América Latina e no Brasil que versam sobre o uso dos isótopos ambientais 15 N NO3 e 18 O NO3 em aquíferos urbanos contaminados por nitrogênio. Na busca por trabalhos em periódicos indexados, foram encontrados apenas cinco estudos na América Latina, conduzidos na Argentina (MARTÍNEZ et al 2014, BLARASIN et al 2020 O Apêndice 1 apresenta as características gerais de todos os artigos consultados, publicados entre 2006 e 2020.…”

“…O pro-cesso de nitrificação teria ocorrido a partir da oxidação de nitrogênio orgânico/amoniacal de efluentes domésticos, seja de fossas (MELO et al 1998, REYNOLDS-VARGAS et al 2006e LEITE 2019, seja de fugas de redes coletoras de esgoto e esterco (VARNIER et al 2013e MARTÍNEZ et al 2014 (Apêndice 1, Figuras 5 e 6). BLARASIN et al (2020) identificaram a presença de desnitrificação em amostras do aquífero de Del Campillo (Figura 5), cujos intervalos de δ 15 N NO3 e δ 18 O NO3 corresponderam de +10,5 a +20,9‰ e de +3,3 a +12,1‰, respectivamente (Apêndice 1, Figura 6), e um fator de enriquecimento (ε) de 2,2.…”
