The present work aimed at studying the effect of drying temperature on the biochemical contents of Spirulina platensis to choose the best temperature that can be used for drying without affecting its contents to be used as a fish diet, with a good quality, low price and to give the immunity to fish in fish farms. Open air and temperatures (60oC and 120oC) were applied for drying Spirulina platensis. The alga was cultivated on large scale in concrete ponds (25 and 50 m3) to be used as fish meal. The crude protein content of the dried matter in S. platensis biomass was 59.1, 63.2, and 64.8% in case of open air, 60oC and 120oC respectively. Also there are no significant differences measured of amino acids content on open air, 60 oC and 120 oC. The nutritional value of protein is due to its amino acids contents which were of 49 %, 49% and 50% for the dried matter at open air and 60oC and 120oC respectively. Also, the lipid contents, carbohydrates, fibers and ash were 0.74%, 20.78%, 0.18% and 8.8% respectively in open air, 0.78%, 18.9%, 0.22% and 8.8% at 60oC and 0.94%, 19.74%, 0.12% and 9.0% respectively at 120 oC. The results revealed that the concentrations of chemical contents (lipid, carbohydrates, fibers and ash) were higher at 120 oC than those at the other two procedures. The concentrations of crude protein (64.8 %) and amino acids (50%) were also higher at 120 oC. It was found that there is no difference between the three procedures of drying but drying at 120 oC saves time and therefore it is better to be used. Sixteen weeks of feeding was conducted to investigate the effect of fish meal replacement with Spirulina on growth performance and body weight. About 20% increase of weight gain and with highly significant average daily gain 0.450 and 0.546 for diet1 (control) and diet 2 (Spirulina diet) respectively and feed conversion ratio were 1.189 and 1.333 for diet1 (control) and diet 2 (Spirulina diet). The use of the harvested alga S. platensis was to solve the problem of availability as protein source not only as fish feed but also saving aquatic environment.

Rosetta branch is a source of fresh water for domestic, agriculture, industry, fisheries and recreation purposes for some western Delta governorates in Egypt. Unfortunately this branch is impacted by increasing concentrations of ammonia resulted from the agricultural drains located along its sides and by the industrial effluents of industrial activities and fish farming cages. This study aims at monitoring ammonia, dissolved oxygen nitrite and nitrate concentration along the Rosetta branch. Samples were taken at an interval of 5 Km of the branch. Ammonia concentrations measured by a colorimetric Nessler method. Recorded ammonia ranged from 0.16 to 7.87 mg/l. Level of ammonia in Rosetta branch is very high after mixing with Rahawy drain, as it reached 6.77 mg/l and decreased gradually along the Rosetta branch to the lowest level of 1.67 mg/l at Kafr Yaqob village due to dilution along the branch and increased again, due to presence of fish cages along Gharbiya, Kafrelsheikh and Behaira governorate.

The textile environmental issues associated with impact represent both cotton agriculture and dyeing processes . Cotton farms emit hazard chemical compounds as Piperonyl butoxide , Cypermethrin, Lambds- cyhalothrin, Chlorpyrifos, Profenofos, Malathion, Lufenuron and Carbendazim. These compounds were detected by multiresidue method analysis for convention cotton in addition to wet processes and dyeing operations ; high BOD,COD,TS, alkaline wastewater and wasted residual unfixed dyes. So this investigation focuses on monitoring of environmental contaminants and eco-production environmental friendly clothes as model which are more healthy for humans and safe on the ecosystem. On using organic cotton instead of conventional cotton, where organic agriculture farms there are no synthetic chemical pesticides, no synthetic fertilizers .The ring spun yarns of 30/1 Ne combed organic and conventional cotton were produced with similar parameters like beating point and settings. Rib knitted fabrics were produced with similar loop length and weight using organic and conventional cotton yarn. The fabrics were processed in eco textile processing by using Levafix Red CA Gran(vinyl sulphone and difluoropyrimidine) reactive dyes by soft flow machine in single dye bath. The fabrics were tested for colour fastness to washing, water, rubbing, perspiration, light and ecological emission measurements.

Pesticides have negative impact on the human health and environment. They were classified as possible human carcinogens. World health organization (WHO) has set a limit for Atrazine (ATZ) at concentration 2 ppb. This work aims to monitor Atrazine in drinking and related raw water of Kafr El Sheikh governorate. Different treatment techniques for Atrazine removal like Fenton reaction and granulated activated carbon (GAC). The identification and quantification of Atrazine was explored using LC/MS/MS spectrometer. The study recorded the presence of Atrazine during summer spring and autumn in drinking and related raw water due to using it as herbicides in corn crops and the highest influent of atrazine was 0.15µg/l. The study showed that water purification steps have no effect on Atrazine treatment. Some trials were carried out to degrades and adsorb Atrazine using Fenton reaction and GAC. 99 % of Atrazine was removed after one hour by using Fenton oxidation, 97% was removed after two hours by using (GAC).

This paper deals with the improvement of soil swelling for purposes of constructions by adding industrial waste Phosphogypsum (PG), in addition to the chemical additive sodium chloride (NaCl) to reduce its expansiveness and improve its characteristics for many earth work construction, the test results showed significant decrease in the swelling properties and pronounced reduction in the liquid limit, plastic limit and plasticity index of the clay by increasing the ratios of PG and NaCl. Also the results from x-ray diffraction (XRD) analyses of bentonit only and the mixture (1.2% PG+3% NaCl+95.8% Bent.) showed that, large amounts of Montmoronite clay mineral were approximately transformed to other phases during the reaction. Reaction products are non-swelling clay mineral commonly Kaolinite this is because, the mineralogy of both clay minerals reflects that, Montmoronite is an immature clay mineral while Kaolinite is a mature clay mineral. This maturity state may be attained through the chemical reaction with these additives. So, the PG industrial waste helps to improve the physical characteristics of soil swelling and the results present a very important factor for constructions purposes.

Polychlorinated dibenzo-para-dioxins (PCDDs) and Polychlorinated dibenzo- furans (PCDFs) may be released during fuel combustion in several industries including cement production. Estimation of dioxins and furans released from four cement factories in the Red Sea region, Suez Governorate, Egypt, has been calculated. The Standardized Toolkit recommended by the United Nation Environmental Program, UNEP for Identification and Quantification of PCDD’s and PCDF’srelease developed by UNEP was used. Data about incineration of hazardous waste in cement kilns are also collected. Only one plant was found to incinerate according to controlled combustion processes that apply good air pollution control system, APCS, in place. The default emission factors established by UNEP toolkit were used to estimate the PCDD’s and PCDF’s. Only one plant allows the use of hazardous wastes, HW, in its fueling mixture. The calculated dioxins and furans for this plant (A) was 0.77 g TEQ/year into air with dioxins residue of 12.135 g TEQ/year. However, emission rate of other plants(B,C and D) were, 0.1165, 0.1 and0.07 g TEQ/year, respectively, compared with the permissible limit set by the European Union as is 0.1 ng TEQ /Nm³ TEQ for concentration of dioxin-like compounds in the discharged flue gas is 0.1 ng TEQ/Nm³ TEQ.( "EU limit value". europa.eu)

Cardiovascular disease is the most prominent circulation disorder around the world and one of the leading cause of disease burden in developing countries as the three fourth of the global deaths due to coronary heart disease occur in the middle income countries. Extreme cold episodes significantly has its impact on health ,especially on the cardiovascular system by different mechanisms. This is a community based study aimed to detect the influence of the surrounding environmental temperature on cardiac function. Apparent healthy individuals submitted for longitudinal study along winter and Summer seasons.
All subjects undergo specified inclusion and exclusion criteria.
All subjects will be exposed to the following investigations at one of the coldest day in Winter (below 14 º C) and one the hottest day in Summer (above 34 º C ):
-measurement of arterial blood pressure.
-local examination of heart.
-recording electrocardiograph ( ECG).
Results of the present study show significant elevation in the blood pressure, associated with cold weather.On the other hand there were no- significant changes in the heart rate or other ECG findings.
From our results we can conclude that apparently healthy individuals display adaptive functional changes in the cardiovascular system during seasonal variation. Cold weather is associated with slight increase in thearterial blood pressure (systolic and diastolic).
