New Pollution Challenges in Groundwater and Wastewater Due to COVID-19

Water is considered one of the most important components of life, alongside atmospheric air. Its pollution represents a serious threat not only to human health but also to the surrounding ecology. Water pollution problems were aggravated in the era of COVID-19. Approximately 80% of global diseases are waterborne, and polluted aquatic environments have been linked to the SARS-CoV-2 virus, which causes the disease COVID-19. Understanding the fate of this virus in aquatic environments like water and wastewater is critical. SARS-CoV-2 may be adsorbed on charged colloidal particles and this process probably depends on the pH of the medium. Other parameters that may influence this process include sorptive interaction with solid particles in soils, aquatic environments and sewage sludge. There are several areas of research that need to be investigated regarding the relationship between SARS-CoV-2 and the transmission of COVID-19 to aqueous environments, including indirect relationships between different aquatic environments (e.g., groundwater, drinking water and wastewater) and outbreaks of COVID-19. Different pathways and the fate of SARS-CoV-2 in water, wastewater and groundwater and subsequent human exposures also need to be determined. These issues will be explored in this review.

The ability of three LAB strains namely, L. brevis, L. plantarum and P. acidilactici to grow and produce SeNPs in MRS or whey media supplemented with 100 or 200 ppm of Se(IV) as sodium selenite (Na2SeO3) was investigated. The presence of Se(IV) in the media retarded the bacterial growth in the first six hours of incubation thereafter, the bacterial growth gradually increased up to 72 hr. P. acidilactici was more tolerable to the inhibitory effect of Se(IV) than the other two strains. Although MRS media was more suitable for the growth of the three LAB strains, as estimated by the reduction of media pH and increase of absorbance compared to whey media, both media showed significantly similar conversion rate (98-100%) of Se(IV) to SeNPs at the end of the incubation period (72 hr). L. brevis, produced smaller SeNPs (125.7 nm) followed by L. plantarum (140.7 nm) and P. acidilactici (176.6 nm). The obtained data demonstrate the possibility of using the whey as a source of low-cost culture media for the production of milk whey based product rich in SeNPs with the assistant of the environmentally friendly LAB for different usage, i.e. as a feed supplement for livestock production.

Gouda cheese was made from cow's milk inoculated with a cheese starter culture ( CSC ) without ( the control C) and with partial replacement of cheese milk with buffalo's milk ( 25%). The mixed milk was CSC with applied in T1, while Lb. helveticus CH5 and Lb. plantarum ATCC 14917 were used separately with CSC in T2 and T3 respectively. Microbiological analysis of fresh cheese and during ripening revealed that Gouda cheese treated with Lb. helveticus (T2), followed by cheese treated with Lb. plantarum (T3) had the highest values in total bacterial count and count of proteolytic and lipolytic bacteria when fresh and during ripening period, while no colonies of yeasts & moulds appeared in all cheese treatments when fresh, but after one month of ripening few colonies were observed. Lb. helveticus CH5 significantly increased during ripening and reached 9.2 log cfu. g-1 at day 60, while the number of the Lb. plantarum ATCC14917 bacteria at the beginning of the maturation period was about 8.2 log cfu g−1then increased at 60 day of ripening (8.8 log cfu g−1 ). The counts of the prementioned bacteria at the end of ripening were more than 7 log cfu/g ,Organoleptically, appearance and colour of control cheese of any age had the maximum scoring points. The control cheese and cheese from T3 ranked the maximum scores for body, texture and flavour and the differences between them were statistically significant. This was noticed in fresh cheese and during ripening period.

Potato whitefly, Bemisia tabaci (Homoptera: Aleyrodidae) is one of the most important pests of potato. Field experiments were carried out during two successive growing winter seasons of winter 2017/2018 and 2018/2019 at the Research station of Faculty of Agriculture Alexandria University, to evaluate the efficacy of six conventional insecticides , emamectin benzoate + thiamethoxam, imidacloprid, etofenprox, fenitrothion, pymetrozine and thiamethoxam against Bemisia tabaci on potato plants (Solanum tuberosum L.,) of variety sponta, either as direct effect or indirect effect during induced resistance and their relationship with crop yield. Results showed that emamectin benzoate+thiamethoxam, thiamethoxam and imidacloprid achieved high reduction percentage of whitefly adults. Also, fenitrothion, pymterozine and imidacloprid achieved high reduction percentage of whitefly immature. Fortunately, these treatments had a positive effect, both on the measures of induced resistance that were estimated, and at the same time they had a promising effect on the potato yield in terms and quality.

This study was designed to determine the effect of Chromium methionine (CrMet) at different levels on growth parameters, blood constituents, immunity, and anti-oxidative properties of growing Japanese quail. A total of 150 7-day old unsexed Japanese quail chicks were randomly distributed to five dietary treatments of thirty birds to a treatment. Each treatment was replicated three times with ten birds to a replicate. Five isocaloric and isonitrogenous diets were formulated. CrMet was added to the basal diet at five different levels being 0, 200, 400, 600, and 800 mg /kg diet, respectively. CrMet supplementation improved body weight (BW) at 6 weeks of age by 2.3%. compared with those on diet 1 (control). Feed intake (FI) increased gradually by increasing CrMet levels in the diets compared with the control group and the group fed on 200 mg CrMet /kg diet. The best (P≤ 0.05) value of feed conversion ratio (FCR) was noticed in group fed 600 mg CrMet /kg as compared with other experimental groups. CrMet improved (P ≤ 0.01) the thymus, heart and testes weights, white blood cell (WBC) counts, hemoglobin (Hb), Packed cell volume (PCV%), and monocytes of growing Japanese quail. Also, Alanine aminotransferase (ALT) and total antioxidant capacity, while albumin, albumin/globulin ratio, aspartate aminotransferase (AST), total lipids, cholesterol, triglycerides, and lipid peroxide concentrations contents decreased significantly (P ≤ 0.01). In summary, inclusion of CrMet in growing quail diets may exert beneficial effects on growth parameters, blood constituents, immunity, and anti-oxidative properties.

An Economic Study of The Impact of Overexploitation on Sustainable Use for Fish Resources in the Egyptian Lake Mariout
Roshdy
Eladawy
Excessive fishing (overfishing) is one of the most important problems facing Lake Mariout, due to its negative impact on the quantity of fish production in the coming seasons, and the lake also faces the causes that led to a decrease in its area from 204 thousand feddans in 1798 to 17 thousand tons in general. The research problem is represented in the fluctuation in the total fish production of the lake and the fluctuation of the main culture production (tilapia) from it to the total fish production in them from 61.38% as a maximum in 2001 to 52.38% as a minimum in 2000. The research aims mainly to identify the effect of excessive fishing on the sustainable use of fishery resources in the Egyptian Lake Mariout. Surplus production models It was found from the estimated results that there is wasteful use of fishing boats in the lake by 273 boats, or about 34% of the maximum number of boats in the lake, as the actual fishing effort exceeded the fishing effort achieved for the maximum sustainable yield, which indicates. The study recommends the continuous review of the maximum permissible number of fishing boats operating in the lake according to technical and economic principles, in order to ensure sustainable use of the materials in the lake, while studying the allocation of fishing boats according to the fishing effort and including them with permits for fishing, in cooperation between the lake administration, fish cooperatives and elders of fishermen.

The study aimed to identify the current status of beans production in Egypt and Sharkia Governorate. The study found that there is an annual decrease in the cultivated area and the total production of beans in Egypt, were -7% . There is an annual increase in the food gap of beans was 9%. There is an annual increase in the total costs per and the net yield of 12%. Once of most important factors affecting the production of the bean crop in the study sample were: the amount of seeds, the number of workers, and the value of pesticides. The costs of producing an feddan of beans was 11369.44 LE, the total revenue was 14924.52 LE. The net return was 3555.08 LEs, the ratio of revenue to costs was 1.31, the profitability of the invested pound was 0.31 LE. Ones of important problems facing bean growers are: Production inputs are high in value, plants are affected by Holoparasites and diseases, pesticides may not be available in agricultural societies. The study recommends the necessity of increasing the production of beans by growing them in the cultivated lands, and the crop is loaded onto other winter crops. Production requirements must be available in agricultural societies, contract farming policy must be applied, or the Government must set a price for the beans before planting them, so that the farmer guarantees an appropriate price for his crop, and also control must be tightened on pesticides in the local market
