Waterbird diversity and its distribution are deemed as one of the essential issues in the ecological conservation of wetlands areas. However, the differences in the diversity of waterbirds in tidal and non-tidal wetlands have been underestimated. This study aimed to identify the variations in bird diversity between tidal and non-tidal areas in East Al-Hammar marsh to guide the efforts of bird and habitat conservation. The bird survey was extended from August 2020 to March 2021, in three selected sites; Slien (non-tidal area), Al-Sallal and Al-Burqa (tidal areas). Twenty-nine species were observed. These species were classified into three categories: migrant 68.96, resident 6.90% and migrants and residents 24.14%. Species richness indices included; number of species, Margalef and Menhienk indices indicated that the highest values were in the Slien site, there were 19, 3.191 and 1.254, respectively. Similarly, Shannon Weiner and Berlion’s indices showed the highest values in Slien. However, the Berker-Berker dominance index revealed the highest value in the Slien site 0.193. Interestingly, the Jaccard similarity index showed the highest measure of 0.791 between Al-Sallal and Al-Burqa, while the highest dissimilarity index of Whittaker was between Slien and Al-Sallal. In sum, the current data analysis demonstrated that non-tidal areas supported higher diversity of waterbirds than tidal marshes.

Studies on ambient PM2.5 exposure and AURI and ALRI in regions such as South and South-East Asia, where levels of PM2.5 are among the highest, are limited. We assessed the associations between ambient PM2.5 exposure and AURI and ALRI in children under the age of 5 years from South and Southeast Asia. We identified subjects from the demographic health survey (DHS). We retrieved PM2.5 information from the Atmospheric Compositional Analysis Group. Annual mean levels of PM2.5 ranged from 21.3 to 73.2 μg/m3. We performed the meta-analytical approach to obtain the pooled results. Our initial results show an association between ambient PM2.5 exposure and AURI (OR 1.06, 95% CI: 1.01-1.11) but not ALRI (OR 1.03, 95% CI: 0.98-1.09). However, after controlling for indoor SHS, effect estimates became stronger for AURI and ALRI (OR 1.27, 95% CI: 1.04-1.54 and OR 1.20, 95% CI: 1.00-1.44) compared to the uncontrolled group. Our study shows an association between ambient PM2.5 exposure and the prevalence of AURI and ALRI in children under the age of 5 years from South and Southeast Asia. Promoting awareness of air pollution in line with the implementation and monitoring of relevant policies is crucial in establishing clean air and health.

In the present research an economically effective porous fly ash-based filter candle (FFC) was developed for the treatment of domestic wastewater using fly ash, sodium silicate, wood dust, silica fume and water. The four testing specimens of FFC having different sizes (10, 20, 30, and 40 mm) were prepared. The parameters such as turbidity, total suspended solids (TSS), dissolved oxygen (DO), total dissolved solids (TDS), and pH of domestic wastewater were studied before and after treatment. The test results showed that there is a decrease in values of turbidity from 7 to 5.9 NTU, TSS from 300 to 218 mg/L, TDS from 400 to 302 mg/L, pH from 10.6 to 7.9, and BOD from 9.5 to 7.9 while DO values decreased in the range of 8.9 to 7.7. The observed porosity, compressive strength, and flow rate of FFC fall in the range of 24.55-27.26 %, 1.5-2.3 MPa, and 180-290 ml/h, respectively. The filtration tests using FFC exhibited good performance with >92 % filtration efficiency. Overall results have shown that FFC having a 30 mm bed thickness is recommendable for effective wastewater treatment. Thus, an attempt has been made to introduce a novel technology for domestic wastewater treatment using industrial fly ash waste.

With the Jordan River as its main tributary, the Dead Sea is a hyper-saline lake, which was formed around 140 centuries ago. Climate change used to be the principal driver of water level changes. However, anthropogenic activities have recently emerged as a prominent source of excessive depletion. This study provides a realistic strategy for desalinating the Red Sea water whilst generating electrical power for the Dead Sea conveyance project. Seawater from the Gulf of Aqaba is transformed into highly concentrated saline water flowing to the Dead Sea whilst delivering purified drinking water to nearby regions using reverse osmosis plants. Being an energy-intensive process, a series of hydro-generators with efficient energy recovery devices will minimise the running cost by half.

The DNA repair enzymes–heavy metal interaction is an interesting project that can help elucidate several diseases. The current study aims to assess the lead effect in the two DNA repair genes RAD-18 Arg302Gln (rs373572) and OGG1 Ser326Cys in Gasoline station workers. The output showed that work types were Gasoline supply worker with a high percentage (73.52%) than other groups (11.76% and 14.7%) for a maintenance worker and station employee, respectively, significant lead (p 0.010) increasing in station worker than the control group, and significant lead changes among work types groups (p 0.000), the station employee has a low level of lead than other groups, while the Gasoline supply worker has a higher level than other groups, the RAD 18 gene showed two polymorphisms Gln/Gln and Gln/Arg, and OGG1 showed two haplotypes, single and double haplotypes, non-significant association although of high frequent of Glu/Arg in the gasoline supply worker, and significant association of allele frequency, significant association with station worker that have two types of haplotypes (single and double haplotypes) while lack of tri-haplotypes which prepared in higher percentage in control group. The lead level according to RAD 18 genotyping show non-significant (p 0.454) elevation in Gln/Arg genotyping, and according to OGG 1 haplotype lead level was non-significant, changed (p 0.481) between single and double haplotypes. From these outputs, it can be concluded that the lead level is a significant elevation in gasoline station worker and it did not affect RA18 and OGG 1 genotyping, the RAD18 did not associate with workers while OGG strongly associated with them.

In the absence of environmental regulation, food stays to be contaminated with heavy metals, which is becoming a big worry for human health. The present research focusses on the environmental and health effects of irrigating a number of crops grown in the soils surrounding the Al-Rustamia old plant using treated wastewater generated by the plant. The physicochemical properties, alkalinity, and electrical conductivity of the samples were evaluated, and vegetable samples were tested for Cd, Pb, Ni, and Zn, levels, and even the transfer factor (TF) from soils to crops and crop and multi-targeted risk, daily intake (DIM) of metals, and health risk index (HRI) was calculated. The findings found that the average contents of Zn, Pb, Ni, and Cd in soil and vegetation were less than the Food and Agriculture Organization’s standards of food safety enhancers. The flooded soil included Zn (56.5), Pb (15.1), Ni (9.30), and Cd (0.850) mg·kg-1. The heavy-metal concentration trend in all samples was Zn, Pb, Ni, and Cd. Daily metal intake in crops species was above acceptable limits for Zinc (0.011 – 0.019 mg·kg-1), Lead (2.010-5 – 5.910-5 mg·kg-1), Ni (2.410-4 – 5.210-4 mg·kg-1) and Cd (1.310-5 – 3.310-5 mgkg-1). The HRI for zinc varied between 0.037 and 0.063, for lead between 5.10-3 and 1.410-2, for nickel from 1.210-2 to 2.610-2, and for cadmium from 1.310-2 to 3.310-2. The HRI for such components was larger than one, suggesting that no possible health issue existed. Crop cultivation using wastewater is a typical solution for water-stressed nations; nevertheless, previous screening and processing of such industrial wastewaters is required to minimise its detrimental effects on the environment.

Detergent serves as the most widely used cleaner, one of the ingredients for detergent is phosphate. Excessive phosphate in the waters will cause eutrophication and endanger the aquatic biota in it. Therefore, a solution is needed to reduce phosphate in the waters; one such way is by using Eichornia crassipes (Mart.) Solms and Marsilea crenata C. Presl. The purpose of this study was to determine the effect of plant species and phytoremediation time on phosphate levels in laundry waste. The variables studied were variations in plant species and phytoremediation time. In the plant variety, water hyacinth, water clover, and a combination of the two are used. In the variation of time used 0, 48 and 96 hours. The waste used is waste from a laundry business in Wonokromo, Surabaya. Parameters tested include phosphate, DO, BOD, pH, temperature, and turbidity. The exploration stage is in the form of acclimatisation and range finding tests to determine the concentration of wastewater used in the experimental stage. The results showed that plant species and phytoremediation time affected the decrease in phosphate levels. The correlation between phytoremediation time on parameters of phosphate levels, BOD, and pH will decrease with the duration of phytoremediation, but DO parameters will increase with the duration of phytoremediation.
洗涤剂是应用最广泛的清洁剂，磷酸盐是洗涤剂的成分之一。水体中磷酸盐含量过高会引起水体富营养化，危及水体中的水生生物群。因此，需要一种溶液来降低水中的磷酸盐;其中一种方法是使用Eichornia crassipes (Mart.)Solms和Marsilea creata C. Presl。本研究的目的是确定植物种类和植物修复时间对洗衣废物中磷酸盐水平的影响。研究的变量是植物种类的变化和植物修复时间的变化。在植物品种上，有水葫芦、水三叶草，以及两者的结合。在时间的变化中使用0、48和96小时。所使用的废物来自泗水Wonokromo一家洗衣店的废物。测试参数包括磷酸盐，DO, BOD, pH，温度和浊度。勘探阶段采用适应环境和测距测试的形式，以确定实验阶段使用的废水浓度。结果表明，植物种类和修复时间对磷水平的降低有影响。植物修复时间与磷酸盐水平、BOD和pH参数的相关性随着修复时间的延长而降低，而DO参数随着修复时间的延长而增加。
