“…Farmers specifically referred to seawater intrusion as a result of overpumping (37%), irrigation with saline water (12.6%), excessive application of fertilizer (10.9%), irregular irrigation patterns (9.2%) and mismanagement by labourers (5%) (Figure 5c). These findings are consistent with the studies of Choudri, Baawain, and Ahmed (2015), Choudri, Baawain, Ahmed, Al‐Sidairi, and Al‐Nadabi (2015) and Choudri et al (2018). Moreover, more than half of the respondents indicated that they do not receive any assistance or recommendations on how to alleviate soil salinity (Figure 5d).…”

“…Additionally, the detrimental effects of intensive and unsustainable agricultural practices, coupled with the use of low‐quality saline water for irrigation, contribute to the problem. Furthermore, the overpumping of groundwater in coastal areas like Al‐Batinah and Salalah leads to seawater intrusion, exacerbating soil salinity levels in Oman (Abdalla et al, 2010; Al‐Ajmi et al, 2002; Askri & Ali Al‐Shanfari, 2017; Choudri, Baawain, & Ahmed, 2015; Choudri, Baawain, Ahmed, Al‐Sidairi, & Al‐Nadabi, 2015; Shammas & Jacks, 2007).…”

Soil salinity threatens agricultural sustainability globally and is a significant challenge in Oman. Previous studies in Oman focused on examining the causality and spatiotemporal variation of groundwater and soil salinity, neglecting farmers' perceptions and attitudes toward salinity management. Therefore, this study evaluates (i) perceptions and attitudes of landowners and farmers toward soil salinity and its management, and (ii) determinants of willingness to use elemental sulfur to alleviate soil salinity in Oman. A questionnaire survey (122 responses) assessed perceptions, attitudes, and knowledge using Likert scales and qualitative questions. Binary Logistic Regression analyzed determinants of willingness to use elemental sulfur. Results reveal variations in perceptions, attitudes, knowledge, and management practices. Most of the respondents were aware of adequate nutrient and water requirements for crops (P<0.05). Respondents rely on social media (38.5%), fellow farmers (32.1%), and personal experiences (11.5%) for knowledge acquisition about soil salinity management. Half of the respondents did not monitor soil salinity, while the other half relied primarily on visual observation. A substantial number (62.6%) of the respondents did not implement any techniques to alleviate soil salinity, while among those who acted, a majority preferred cultivating date palms (55%) or fodders (29.4%). Awareness of the national salinity management strategy and commercial products is lacking. However, when introduced to elemental sulfur as a soil amendment for salinity, 74.8% of the respondents demonstrated a willingness to utilize it. Most (82.4%) preferred elemental sulfur products within the lowest price range. Being a full‐time farmer, owning a farm, awareness of the national strategy, and low‐price preferences were positive determinants, while <1 year farming experience was negative determinant to willingness to use elemental sulfur. These findings inform future research on socio‐economic perceptions of salinity in Oman, the Gulf region, and similar arid areas facing food production limitations.

“…It is suggested that the bioaccumulation of organic compounds in an aquatic environment is more related to partitioning coefficients than their absolute exposure concentrations. Furthermore, the fate of the environmental contaminants is not only affected mainly by their physio-chemical characteristics, but also biological processes including environmental parameters that play a critical role in the uptake of these chemicals [44][45][46][47]. Biological factors including individual size, life cycle, feeding type, lipid content, respiration strategy, habitat and metabolic processes may affect the uptake and sensitivity of individuals to the contaminants [48][49][50]; however, the available information is still limited [51].…”

In the modern world, organic chemicals have extensively been used in a variety of industries, including pharmaceuticals, fuels, beverages, foods and agricultural products [1-3]. However, limited information is available about their potential risk to the environment-especially in developing countries because of time and economic constraints [4-6]. In aquatic systems, it is often difficult to make relationships of cause and consequences for aquatic life [7]. So far, different efforts have been made to look into other avenues, i.e., physico-chemical properties, different biological barriers and modelling of existing data to address the toxic potential of pollutants [8-12]. Among different physico-chemical properties (e.g., adsorption forces at surface, solubility, hydrogen bonding, lone-pair electrons, chemical polarity and polarizability among different atoms and molecules)

“…Different studies reported their effects on physiology, which can lead to the development of chronic degenerative diseases with epidemiological impact [1][2][3]. The residues of these compounds have been reported in food, water, sea life, birds, and biological substrates such as different tissues and breast milk [4][5][6][7][8].…”

Permethrin (PERM) is a member of the class I family of synthetic pyrethroids. Human use has shown that it affects different systems, with wide health dysfunctions. Our aim was to determine bioenergetics, neuroinflammation and morphology changes, as redox markers after subacute exposure to PERM in rats. We used MDA determination, protein carbonyl assay, mitochondrial O2 consumption, expression of pro-inflammatory cytokines and a deep histopathological analysis of the hippocampus. PERM (150 mg/kg and 300 mg/kg body weight/day, o.v.) increased lipoperoxidation and carbonylated proteins in a dose-dependent manner in the brain regions. The activities of antioxidant enzymes glutathione peroxidase, reductase, S-transferase, catalase, and superoxide dismutase showed an increase in all the different brain areas, with dose-dependent effects in the cerebellum. Cytokine profiles (IL-1β, IL-6 and TNF-α) increased in a dose-dependent manner in different brain tissues. Exposure to 150 mg/kg of permethrin induced degenerated and/or dead neurons in the rat hippocampus and induced mitochondrial uncoupling and reduction of oxidative phosphorylation and significantly decreased the respiratory parameters state 3-associated respiration in complex I and II. PERM exposure at low doses induces reactive oxygen species production and imbalance in the enzymatic antioxidant system, increases gene expression of pro-inflammatory interleukins, and could lead to cell damage mediated by mitochondrial functional impairment.
