AbstractThe present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and o...... hiện toàn bộ
Forest roads are the base infrastructure foundation of forestry operations. These roads entail a complex engineering effort because they can cause substantial environmental damage to forests and include a high-cost construction. This study was carried out in four sample sites of Giresun, Trabzon(2) and Artvin Forest Directorate, which is in the Black Sea region of Turkey. The areas have both steep...... hiện toàn bộ

Colored effluents are one of the important environment pollution sources since they contain unused dye compounds which are toxic and less-biodegradable. In this work removal of Acid Red 14 and Acid Red 18 azo dyes was investigated by acidic treated pumice stone as an efficient adsorbent at various experimental conditions. Removal of dye increased with increase in contact time and initial dye conce...... hiện toàn bộ

Heavy metal concentrations and magnetic susceptibility of sediment samples were analyzed as indicators of urban and industrial contamination in Anzali wetland in Gilan, Iran. The aim was to investigate the suitability of magnetic properties measurements for indicating heavy metal pollution. The concentration of six heavy metals (Ni, Cr, Cd, Zn, Fe, and Pb) was determined in different depths of fou...... hiện toàn bộ
This is an investigation concerned with studying the possible adaptive response of four different unicellular algae, Anabaena PCC 7120, Oscillatoria angustissima, Scendesmus obliquus and Chlorella vulgaris, to the toxin of Microcystis aeruginosa (Kützing). The effects of four different concentrations, 25, 50, 100 and 200 μg mL-1 of microcystins crude extract of M. aeruginosa, on both intra and ext...... hiện toàn bộ
Nghiên cứu này đã điều tra và so sánh khả năng loại bỏ arsenic, As (V) của đá nhẹ phủ nhôm và zeolit. Kính hiển vi điện tử quét (SEM), Phân tích tia X (XRD) và Quang phổ phát xạ tia X (XRF) đã được thực hiện để xác định tính chất của vật liệu hấp phụ. Nhiều thông số bao gồm liều lượng vật liệu hấp phụ, pH, thời gian tiếp xúc và nồng độ As(V) ban đầu đã được nghiên cứu. pH tối ưu đạt được cho cả ha...... hiện toàn bộ
