This study was carried out to evaluate the groundwater quality of tube wells along the length of Nullah Lai, the main sewer line of the Federal area of Pakistan. Water samples from eight locations were taken from the nearby tube-well sources of the public water supply, and analyzed for the water quality parameters using standard procedures. About twelve different physcio-chemical and biological water quality parameters were studied, depending upon their importance in the subject area. The results obtained indicated that the water quality is within the limits of the available water quality standards in terms of physical and chemical parameters, but is very much contaminated with microbial pollutants, which needed to effective disinfection prior to drinking usage. The maximum pH, turbidity, TDS, Nitrates, Chloride, and Total Coliform recorded in the studied area was 8.2, 3 NTU, 645 mg/L, 9 mg/L, 362 mg/L, and 47 MPN/100 mL, respectively. The results of this study suggested that the drinking water sources of the surrounding vicinity were at greater risk in terms of pollution carried by the Nullah Lai stream in Pakistan.

Classification of five Iranian chemical industries based on economic value-added
Malek
Hassanpour
The value that is added to the value of intermediate goods in the production process is called Economic Value-Added (EVA). This concept is related to the production process and not to a specific commodity. Due to the wide variety of goods required, most of the needs of society are provided by the Chemical Industries Group. Chemical industries are part of the industry, which convert the chemicals needed by other industries to produce more than 70,000 products through conversion. Raw materials supply the required materials. Sales of the chemical industry can be divided into several broad categories, including basic chemicals (about 35 to 37% of production), life sciences (30%), particular chemicals (20 to 25%), and consumer products (About 10%). The tabulated data were selected from the screening step of project identification in the Environmental Impact Assessment (EIA) plan of industrial projects belong to both the Iranian environment protection agency and Iranian industries organization. To classify the five Iranian chemical industries was employed EVA using empirical equations. Results were allocated for depreciation outlay, and unforeseen costs via considering the percentage of outlays of required land, landscaping, buildings, pavement, and asphalt; Investment in facilities; Investment in equipment and the installation costs; and investment in transportation facilities. Finally, the industries were assorted based on EVA from the highest percentage manifested to the lowest one as well as simple reports of costs in tables. Findings declare that the screening step of industrial projects in project identification is an indispensable stage in conducting an Environmental Impact Assessment (EIA) plan.

During this experiment, the effects of cow manure and cow manure + sawdust vermicompost replacement instead of peat in the growth media were investigated on the growth of ornamental foliage plants Aglaonema (Chinese evergreen), Dracaena marginata and Spathiphyllum wallisii. To produce vermicompost, cow manure and cow manure + sawdust (volume ratio 80 to 20) was added to Eisenia fetida earthworm medium. After preparation of vermicomposts for preparation of growth media, volumetric values of 25, 50, 75, and 100% vermicompost of cow manure and cow manure + sawdust replaced peat in the control (peat + perlite with a volume ratio of 2 to 1). After preparing the growth media, rooted cuttings were planted in them. Measured factors were nitrogen, potassium, calcium and magnesium in leaves and growth medium, height, diameter, fresh weight of stems and leaves, dry weight of stems and leaves and fresh and dry weight of plant roots. The results showed that increasing the levels of two types of vermicompost in peat replacement increased nitrogen, phosphorus, potassium, calcium and magnesium of the leaves in Aglaonema, Dracaena marginata and Spathiphyllumwallisii. With increasing two types of vermicompost in the growth medium, water holding capacity increased compared to peat and 100% vermicompost had the highest water holding capacity. Application of 25% of each vermicompost increased the height, diameter, fresh weight and dry weight of branches and leaves in plants compared to the control. Due to the problems caused by the accumulation of sawdust in the environment and the high cost of peat in the ornamental plant industry, the use of 25% cow manure + sawdust vermicompost is a more economical recommendation.

The purpose of this study was to determine the effect of green intelligence education on environmental experience, environmental citizenship behavior and relationship with nature of students. The research method was a semi-experimental study with pretest-posttest design with two groups of experiment and control. The population of this research was all 36350 elementary school students in Bojnourd, and the sample size was 35students in experimental group and 35 studentsin control group by cluster sampling method. Data gathering tools in this study were questionnaire of Nature Guard Gardner and Moran, (2006), a researcher-made environmental experience questionnaire (2017), HeidariArjlou’s Environmental Citizenship Behavior Questionnaire (2015) and Nature Relationship Questionnaire by Nisbet et al., (2009). The validity of all questionnaires has been confirmed by experts. This test was carried out between the sample groups considered based on acceptance and commitment. In order to test the research hypotheses and answer the research questions, the inferential statistics method of Covariance Co-analysis (Equation of Variance) was evaluated by SPSS-22 software. The findings of this study showed that green education training was effective on environmental experience, environmental citizenship behavior and relationship with nature of students. Therefore, training for education of green intelligence will improve the environmental experience, the citizenship behavior of the environment and the relationship with the nature of the students.
