“…Sulfur dioxide can cause damage to plant tissues by entering the stomata and reacting with water to form sulfuric acid. This can result in reduced crop yields, forest decline, damage to vegetation in the affected area, alongside reduced availability of food and food products and consequent problems of starvation and malnutrition [21,33,42]. Inhalation of nitrogen dioxide and other nitrogen oxides can cause respiratory problems, particularly in individuals with pre-existing respiratory conditions.…”

The practice of artisanal refining of crude oil remains rampant within the Niger Delta region of Nigeria with consequent pollution and destruction of the environment as well as exposure of the human population to various pollutants known to cause health problems. It was thus necessary to conduct this study to assess the quality of water and air in communities where artisanal refining of crude oil is carried out in Ekeremor, Bayelsa state, Nigeria. This was a comparative cross-sectional study that was conducted in Peretorugbene community in Ekeremor Local Government Area of Bayelsa state. Water samples from five points (L1-L5) in the study site and one control site (LX were obtained and assessed. Also, air quality assessments were conducted and results were comparatively assessed for significant differences between test and control sites. Results revealed that the water samples from the third sampling site (L3) had the highest levels of chromium of 0.100±0.055, while the first sampling site (L1) had the highest levels of lead of 5.225±0.687. Heavy metals’ concentrations from the water samples obtained from the artisanal refining sites significantly differed from the concentration of the samples from the non-artisanal refining site (p-value: 0.006 [for chromium], p-value: <0.001 [for lead]). Assessment of the concentration of noxious gases in the air at these two differing sites revealed that the carbon monoxide (3.110±0.160), nitrogen oxides (2.870±0.212), and sulfur oxides (2.557±0.105) from the first sampling site (L1) were the highest, and carbon monoxide and nitrous oxides concentration at the non-artisanal refining site was significantly lower from the concentrations at all the artisanal refining sites (p-value: <0.001). Also, the turbidity, temperature, and salinity of the water samples exceeded the allowable standard limits, alongside the lead, cadmium and mercury levels. In this study, it was thus concluded that the turbidity, temperature, and salinity of the water samples exceeded the allowable standard limits, while the conductivity, and total dissolved solids (TDS) in the water samples were below the acceptable standards. Also, the assessed air quality parameters were found to exceed the laid down allowable limits. It was recommended that stakeholders at the federal level of government should strengthen and enforce regulations specifically targeting artisanal refining activities in order to control and monitor their environmental impact.

“…Thus, it is well established that stomata movement as it has happened with photosynthesis activity can be affected by numerous atmospheric pollutants [ 63 , 64 , 65 , 66 , 67 , 68 ].…”

“…At present, it is known that plants can emit • NO [ 11 , 69 , 70 , 71 ] and H 2 S [ 12 , 72 , 73 ] to their surrounding atmosphere; however, plants could also release other gases such as CO 2 , nitrous oxide (N 2 O) [ 74 , 75 ] and methane (CH 4 ) [ 76 , 77 ] which are part of the greenhouse gases that contribute to global warming. At the same time, it is important to note that atmospheric • NO/NOx and H 2 S may be adsorbed at the leaf’s surface through the stomata [ 65 , 78 , 79 , 80 ], and depending on their concentration, these gases can have either negative or beneficial effects on higher plants. For example, it has been pointed out that • NO seems to be a key signaling molecule in the mechanism of response against higher levels of atmospheric gases including CO 2 , N 2 O, CH 4 , or O 3 which usually provoke stress in plants that have associated oxidative stress because they trigger an uncontrolled increase in the generation of ROS and RNS associated with a lower antioxidant capacity [ 81 ].…”

“…On the other hand, ethylene induces H2S production in guard cells and this H2S can then inhibit the synthesis of ethylene by the inhibition of 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) activity by persulfidation (Cys-SSH) at Cys60 [62]. Thus, it is well established that stomata movement as it has happened with photosynthesis activity can be affected by numerous atmospheric pollutants [63][64][65][66][67][68].…”

Atmospheric stressors include a variety of pollutant gases such as CO2, nitrous oxide (NOx), and sulfurous compounds which could have a natural origin or be generated by uncontrolled human activity. Nevertheless, other atmospheric elements including high and low temperatures, ozone (O3), UV-B radiation, or acid rain among others can affect, at different levels, a large number of plant species, particularly those of agronomic interest. Paradoxically, both nitric oxide (NO) and hydrogen sulfide (H2S), until recently were considered toxic since they are part of the polluting gases; however, at present, these molecules are part of the mechanism of response to multiple stresses since they exert signaling functions which usually have an associated stimulation of the enzymatic and non-enzymatic antioxidant systems. At present, these gasotransmitters are considered essential components of the defense against a wide range of environmental stresses including atmospheric ones. This review aims to provide an updated vision of the endogenous metabolism of NO and H2S in plant cells and to deepen how the exogenous application of these compounds can contribute to crop resilience, particularly, against atmospheric stressors stimulating antioxidant systems.

This work describes the green synthetic process for magnesium sulfide nanoparticles (MgS NPs) using an extract from Hordeum vulgare leaves. An examination of the MgS NPs was performed utilizing X-ray diffraction (XRD), UV-visible spectroscopy, and scanning electron microscopy (SEM) techniques. The MgS NPs generated were spherical and had a high level of purity. They had a band gap of 2.0 eV, a uniform distribution, and an average crystal size of 14 nm. The MgS nanoparticles synthesized exhibited several geometrical morphologies, including spherical, rod-shaped, and bean-shaped structures. The nanoparticles exhibited an average size of 5 nm, with a band gap of precisely 4.85 eV. The efficacy of MgS NPs on Brassica nigra and Trigonella foenum-graecum for seed priming, germination rate and time, root length, and shoot length has been assessed using different doses. Optimal germination occurs at concentrations of 15mg/100ml and 20mg/100ml, while germination is impeded when the concentration surpasses 30mg/100ml. MgS NPs exhibit a diminutive size and elevated reactivity, which allows them to augment the water absorption and nutrient control capacities of seeds. Consequently, this promotes the germination process and plant growth by decreasing the average duration of germination. Seeds of Brassica nigra and Trigonella foenum-graecum that had been subjected to treatment with MgS NPs had enhanced average root and shoot lengths, as well as accelerated germination. The results of this study suggest various promising opportunities for investigating the application of environmentally friendly nanotechnology to improve agricultural practices.
