However, microplastics abundance, distribution, and polymer types in surface sediment from Euphrates River were reported for the first time. Microplastics were found in all sediment sites along the river, and abundance ranging from 29.6 to 120.0 particles/kg dry, with an average 86.7 particles/kg dry. Fiber particles were the most predominant form (57.1%), followed by films (29.6.2%) and fragments (13.1%). The polymers identified using Fourier Transform Infrared Spectroscopy (FTIR) which was dominantly polyethylene (44.1%), polyethylene terephthalate (35.0%) and nylon (20.2%). It is clear that the microplastics levels in sediment from Euphrates river were polluted and these data will be useful for manage and rehabilitation the Iraqi rivers to reduce possible microplastics pollution.

In this study, an attempt was made to eliminate the validity of Al-Dujaila Channel Project water for human consumption by using the National Sanitation Foundation Water Quality index (NSFWQI). Where water quality for human consumption was found to range from poor to medium. The values of sodium percentage ratio for two periods range between 28-34.4, with respect to the RSC value Almost 100% of the samples indication negative values, which indicated that dissolved Ca2+ and Mg2+ concentrations were higher than HCO3- content. However, all samples are safe for irrigation purposes where the RSC values were less than 1 meq/l, According to Killy ratio all the samples are save for irrigation.

The water quality index (WQI) was calculated using 11 important parameters according to the assigned weight, and its values were used as the dependent variable in stepwise multiple linear regression (MLR) analysis to develop a water quality model (WQM) for the river. Twenty-three physicochemical water quality variables (2760 values) were included in developing the WQM , they are: Aluminum (Al + 3 ), Fluoride (F−1), Nitrite (NO 2 − 1 ), Nitrate (NO 3 − 1 ), Ammonia (NH3), Temperature (T), Total Alkalinity (TA.), Turbidity (Tur.), Total Hardness (TH), Calcium (Ca + 2 ), Chloride (Cl−1), Magnesium (Mg + 2 ), Potential of Hydrogen (pH), Electrical Conductivity (EC), Sulfate (SO4 − 2 ), Total Dissolved Solids (TDS), Iron (Fe + 2 ), Silica (SiO2), Phosphate (PO 4 − 3 ), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and Sodium (Na + 1 ). The annual WQI mean value during the study was 266; more than the safe value of 100; consequently, the water quality was considered as unsuitable for drinking. Significant differences in WQI values were detected over the months and across stations with the highest WQI values (poor quality) in winter and spring, while the lowest values (better quality) were in summer and autumn. The WQM, which was developed based on the stepwise MLR analysis, consisted of five parameters: Tur, EC, COD, TH, and pH with significant value (r 0.987, R2 0.974, p WQI = ( − 1 . 597 ) ( T u r ) 0 . 478 (EC) 0 . 409 (COD) 0 . 089 (TH) 0 . 291 (pH) 0 . 095 The study results show that the use of WQI as the dependent variable input improved the prediction of MLR model as a tool to understand, simplify and model the water quality variation. The model developed here can help in rapid low-cost water quality evaluation for best management of the Tigris River.

The concentrations of total and bioaccessible metals from different stations were in the range of 0.49-1.04, 0.10-0.32 μg g(-1) for T-Cd, Bio-Cd, respectively, and 12.9-128.03, 2.06-8.53 μg kg(-1) for T-Hg, Bio-Hg, respectively. The results revealed highest R-Bio-Cd in Banting station (55.3 %), while the highest R-Bio-Hg was in Kajang station (49.61 %). The chemical speciation of Cd in most sampling stations was in the order of oxidisable-organic > residual > exchangeable > acid-reducible, while speciation of Hg was in the order of exchangeable > residual > oxidisable-organic > acid-reducible.

Multivariate techniques were used to apportion the sources of the metals. The results showed that the highest concentration of metals in the Langat River were found at Jenjarom station, with the concentration of these metals decreasing in the order of Sn>Cr>Ni>Cd (114.27, 21.03, 7.84, 0.59μgg(-1) dry weight). The level of pollution in the sediment was assessed using contamination factor (CF), pollution load index (PLI), geo-accumulation index (Igeo), and enrichment factor (EF). The results of the pollution assessment showed that the Langat River sediments have severe enrichment of Sn and moderate to severe enrichment of Cd. The results of the PLI for the Langat River suggest that the sampling stations are not polluted with the exception of the Jugra, Jenjarom, and Jalan Hulu Langat stations.

Samples were taken from seven agricultural areas in Al-Qadisiyah Governorate, and the heavy elements, including lead, zinc, cadmium, nickel, copper and chromium, were examined by atomic spectrometry. In order to know the extent of the danger of these elements in the soil and their impact on human health, pollution indices and SBET were used for this purpose. The results showed the highest value of relative bioaccessibility of lead (76.14%) in Ghamas, while the lowest value was (32.5%) in Afak. The largest value of the relative bioaccessibility of cadmium was found in Afak (82.22%), and the lowest value (30.24%) in the city of Shamiya. The pollution load indices revealed agricultural soils of Al-Qadisiyah Governorate ranged from light pollution to high pollution so that the lowest pollution values were for Zn to all a...

It may be more effective to manage pollution in waterways if we can better understand the connection between heavy metals in sediments and their accumulation in green mussels. In this study, lead levels in green mussels (Perna viridis) were above the permissible maximum level (WHO, Malaysia Food Regulation, and the FAO). Moreover, zinc levels exceeded the FAO's maximum recommended range. The fractionate of heavy metals in surface sediment from the eastern part of the Johore Straits was investigated using the sequential extraction techniques (SET) method. In the majority of sampling stations, copper's chemical speciation followed the following order: residual > oxidisable-organic > exchangeable > acid reducible, while zinc's and lead's chemical speciation followed the following pattern: residual > oxidisable-organic > acid reducible> exchangeable. The results of Pearson's correlation studies demonstrated a substantial association between Zn concentration in the tissues of green mussels and total Zinc, exchangeable (F1), acid-reducible (F2), and residual (F4) Zn in surface sediment. Green mussel Cu content and surface sediment Cu of exchangeable (F1), residual (F4), and total Cu were found to correlate. As a result, green mussels are being used as a biomonitoring agent for heavy metal contamination on the eastern side of the Straits of Johor in Malaysia.

However, Marsh Dalmaj stands as a vital sanctuary for migrating birds, harboring remarkable biodiversity that underscores the need to prioritize the conservation of wetland avifauna. The study spanned from September 2020 to August 2022. Our methodology encompassed several techniques: (KDE) was employed to delineate suitable and non-suitable habitats, Hotspot Modeling determined the fidelity of suitable habitats, the LST and NDVI algorithms were utilized to monitor climate change, the point count protocol (PCP) enabled precise recording of wetland bird species, and the Adaptive Neuro-Fuzzy Inference System (ANFIS) was employed to predict future scenarios over a span of 50 years. In 2021, the average LST in suitable habitats was 42.37°C, accompanied by an NDVI value of 0.33. In contrast, non-suitable h...

The physical-chemical properties and heavy metals of agricultural soils were examined. The results showed that highest value was Ni (189.9 mg/kg) followed by Cr (124.5 mg/kg), Zn (50.8 mg/kg), Cu (36.9 mg/kg), Pb (35.2 mg/kg) and Cd (1.17 mg/kg). Moreover, Ni and Cr concentration levels were higher than Canadian soil guidelines. Geostatistical analysis was applied to know the sources of heavy metals in agricultural soil and results were revealed that Zn, Cu, Ni, and Cr were the same pollution sources and Cd and Pb also were the same pollution sources indicating these elements impacted by anthropogenic activities. The Pearson correlation coefficients found some physical-chemical properties role in increasing heavy metals in the soil such as EC and Cu, and also TOC, OM and Cr. Therefore, these results a...
