“…Research in the study region has shown an environment with moderate levels of contaminants [11,22], but these levels already pose a potential risk to human health [23][24][25][26]. Epidemiological studies have shown damage to health from exposure to coal [27][28][29][30], but the information on maternal and neonatal outcomes is still scarce in Brazil.…”

Brazil has one of the largest mineral coal reserves in the world. More than 40% of this ore is in the Candiota Mine, in the extreme south of Brazil, which was previously identified as a hotspot of environmental pollution. In addition, an important part of Brazil’s population suffers from socioeconomic vulnerability. Since there is no information on unfavorable gestational and neonatal outcomes associated with these problems, we conducted a cross-sectional study with 1950 mother–child binomials, aiming to evaluate the association between these outcomes and air pollution as well as socioeconomic, demographic and health variables in seven cities in the region. Of the total births, 11.6% were preterm and 9.5% of neonates had low birth weight (<2500 g). These conditions were also associated with skin color, previous abortions, birth type and prenatal care, as well as exposure to higher levels of coarse particulate matter (PM10) during the first trimester of pregnancy. Regarding air pollutants, although the daily limits for PM10 were exceeded on less than 5% of days, the annual average overtook the values proposed by WHO. Thus, we concluded that prematurity and low birth weight in this region are related to air pollution, and to socioeconomic variables and health care.

“…For several decades, the continuous spread of organic and inorganic fertilizers, as well as the application of sludge from wastewater treatment plants as fertilizers, has progressively led to the accumulation of the metals in soils. The soil pollution with heavy metals is persistent due to the long half-time persistence of the contaminants in the environment and can be harmful along the whole food chain [9,10].…”

While heavy metals (HM) have been considered in recent decades to be the most common and problematic pollutants, the expansion of the list of pollutants due to the active use of carbon nanotubes (CNT) raises new questions about the benefit and harm of HM released to nature individually or fixed on CNT walls. A pot experiment was conducted to compare the effect of two classes of potential pollutants—metal salts of Pb, Mn, Cu, Zn, Cd, and Ni; and functionalized CNTs with COOH, MnO2, Fe3O4, and MnO2-Fe3O4—applied in soil, on the elemental transfer, the bioactive compounds accumulation, and the antioxidant activity in lettuce. While CNTs mainly increased the elemental transfer from soil to leaves, HM salts strongly obstructed it. In the presence of CNTs, the antioxidant activity in lettuce leaves correlated with the transfer of elements from soil to root and from root to leaves. The excess of HMs in soil induced a greater variation of the polyphenols quantity and antioxidant activity than the excess of CNTs. It might be assumed that lettuce perceived HMs as a more aggressive stressor than CNTs and more strongly activated the defense mechanism, showing the reduction of the element transfer and enhancing of total polyphenol production and antioxidant activity.

“…Thus, these waters fed by the Upper Devonian and Cretaceous aquifers can be recommended for the water supply of the populations with iodine deficiency. Ramires et al (2022) studied the assessment and spatialization of the risk to human health of potentially harmful elements (PHEs) in the soil for children and adults living in the coal Candiota mines, Brazil. The no carcinogenic risks (HQ) of Cu, Pb, Zn, Ni, Cr, Fe, Mn, Cd, as and Se and carcinogenic risks of As were estimated and spatialized.…”

In the following paragraph, I will summarize the content and main results of these papers published in this Special Issue. The order of papers is based on submission date. Content and main results of the papers of this Special IssueEl-sherbeny et al. ( 2022) conducted an experiment on nitrogen fixation (NF) in an experimental farm with a drip irrigation system, at the Atomic Energy Authority, Inshas, Egypt, in order to measure the impact of efficiency symbiotic Bradyrhizobium sp. and asymbiotic Azotobacter sp. on NF, from air and soil, in the presence or absence of plant residues on the growth and yield of peanut plant. Bradyrhizobium sp. inoculation showed nearly the same levels of nitrogen derived from air (Ndfa) to those recorded with Azotobacter sp. in both the presence and absence of plant residue application through the two seasons. Results show that both possibility of NF of peanut and nitrogen uptake in the soil are enhanced by field J. Bech (*
