Of the critical environmental crisis should refer to global warming, overcrowding, decreasing natural resources, garbage disposal, ozon layer destruction, deforestation, rainfalls, water pollution, public health issues, and genetic engineering. Men around the Iran are experiencing new and challenging environmental problems daily. Some of these problems are likely to affect the health of the ecosystem, but somehow they change the recent landscapes. The planet is on the verge of a massive environmental crisis. Environmental problems in Iran also make human beings vulnerable to natural disasters occurs currently and in the future, as well. So due to the growing problems of the environment in Iran, this is an emergency situation. Therefore, the current environmental situation greatly needs urgent consideations and many factors to be addressed. By increasing community awareness and concern about issues, it can help to create a more friendly environment conscious for survival.}, keywords = {Environmental awareness,Environmental Issues,Crisis,Global warming, Iran}, url = {http://www.cas-press.com/article_103703.html}, eprint = {http://www.cas-press.com/article_103703_75bef666498ae8a07ff7f4288821753f.pdf} } @article { author = {Usman, Adamu Kyuka and Abdullahi, Hauwa and A.Opara, Jacinta}, title = {Forest resources management using geospatial tools (Case study: Northern Nigeria)}, journal = {Central Asian Journal of Environmental Science and Technology Innovation}, volume = {1}, number = {1}, pages = {12-20}, year = {2020}, publisher = {Central Asian Scientific Press (CAS-Press)}, issn = {2717-4034}, eissn = {2717-0519}, doi = {10.22034/CAJESTI.2020.01.02}, abstract = {The present study investigates the reliability of Remote Sensing (RS) and Geographical Information System (GIS) in monitor and management of vegetation resources for sustainable development. Vegetation change is a major environmental problem experienced in different land use types particularly in lands under uncoordinated practices.. Landsat MSS satellite images, Landsat Operational land imager and field survey were used. Results revealed that woodland (6.5%) and crop/bare land (8.1%) experience a steady decreasing trend. Moreover, annual rate of change for crop/bare land is alarming culminating to about plus 50% during the study, while that of woodland and grassland has been minus 15.59 and 3.9%, respectively. This clearly suggests that vegetation resource in the study area is rapidly decreasing and therefore needs urgent attention. Hence, due to crucial importance of vegetation cover in the provision of food, shelter, wildlife habitat, fuel, daily supplies of medicinal ingredients and paper, forest resources management using geospatial tools is highly indispensable for sustainable development. }, keywords = {Remote Sensing,GIS,Forest management,Vegetation Change,Northern Nigeria}, url = {http://www.cas-press.com/article_95589.html}, eprint = {http://www.cas-press.com/article_95589_20c60905ac238a355d92cf1211cfd097.pdf} } @article { author = {Qayyum, Sadia and Khan, Ibrar and Meng, Ke and Zhao, Yangguo and Peng, Changsheng}, title = {A review on remediation technologies for heavy metals contaminated soil}, journal = {Central Asian Journal of Environmental Science and Technology Innovation}, volume = {1}, number = {1}, pages = {21-29}, year = {2020}, publisher = {Central Asian Scientific Press (CAS-Press)}, issn = {2717-4034}, eissn = {2717-0519}, doi = {10.22034/CAJESTI.2020.01.03}, abstract = {The Today, synthetic products such as industrial waste, pesticides, batteries, paints, and industrial or domestic sludge widely applied, as well as and manufacturing can adversely result in heavy metal contamination of urban and agricultural soils.

Among the rivers of Iran, the Haraz River, with a length of about 180 km in Mazandaran province, is one of the most important and most popular among them, which is one of the common activities in those cold-water fish farms. These farms, through the discharge of their effluent, may lead to environmental pollution and threaten the continuation of aquatic life in the river. Therefore, the purpose of this project was to study large communities of macrobenthic inoculants to evaluate the impact of contaminants on the biological conditions of this ecosystem in the months of October, November, December and in two Niyak areas (including 3 stations N1, N2, and N3 ) And Gazanak (including 3 stations G1, G2, and G3). The frequency of benthos samples from Baetide sp. (40.31%), Caenidae sp. (17.37%), Plecoptera sp. (9.04%), Hydropcyche sp. (16.03%), Chironomidae (13.80%) and Tubifex (3.45%) were counted. In order to investigate the relationships between quantitative traits, the Pearson correlation coefficient, the analysis was performed using SAS software version 4.9, and mean comparison using Duncan's multiple range test. The error level for all attributes was considered 0.05. The results show an increase in the relative pollution of station 1 (Niyak) towards station 6 (Gazanak), which can be said at station G2, the highest percentage of pollution and the lowest rate of pollution at station N1. Based on the Pearson correlation coefficient, Benthos of the Chironomidae and Tubifex family which indicate water pollution, according to the measurements of all water qualitative factors such as BOD, COD, DO, EC, Temp, pH, nitrate, phosphate, carbonate, ammonium, TDS, and chlorine in the research records, with all the factors except to DO, the direct relationship and other benthoses that are usually indicators of freshwater, are related to all factors, except DO.

Results demonstrate the inhabitants have not accessed to proper sanitation facilities in most of the rural settlements.

The objective was to establish the presence of Contaminants of Concern (COC), determine, quantify and model spilled volumeIEEE Transactions on Components, Packaging, and Manufacturing Technology and ascertain potential health risks associated with the spill incident. The COC included Total Petroleum Hydrocarbons (TPH), Polyaromatic Hydrocarbons (PAH), and BTEX compounds. Groundwater was sampled in the vicinity of the spill incidents and further away into the surrounding communities. Groundwater assessment showed that TPH ranges from 9.04 to 20,600 µg/L with a mean value of 2526.90 ± 6392.40 µg/L. Apart from four boreholes, all others had TPH values exceeding the DPR target value of 50 µg/L. PAH was recorded only at three boreholes, with values: 0.13, 1.07, and 0.25 µg/L, respectively. Meanwhile, BTEX compounds had concentration (5910 µg/L) that exceeded the Directorate of Petroleum Resources (DPR) target value of 0.8 µg/L over 7000 times. The BW-3 is most deteriorated in water quality. These contaminated borehole-sampling locations are positioned at the vicinity of the tank farm, at higher hydraulic heads and hence, might not pose much health risk to the surrounding communities. Groundwater movement in the area is towards the Bonny River in the southwestern part of the area. This study, therefore recommends remedial actions be taken immediately to prevent health risks in the tank farm area. }, keywords = {borehole,Contaminant,Groundwater,Hydrocarbon,Spillage,Tank farm}, url = {http://www.cas-press.com/article_97281.html}, eprint = {http://www.cas-press.com/article_97281_6306c2a5f3493adca1685911621cea93.pdf} }
